공지사항

Dear APMSX users,

 

I tested it with the latest firmware version with APMSX.

And It little had access issue while running on Turbo mode on APMSX.

I updated the driver in APMSX.HDV so, You can download again with the given link.

 

And Below  image is a BOLD demo disk and you can use it to test MSXDOS.

bold.HDV
0.70MB

How to load the image on APMSX.

 

1) Select D1: APMSX.HDV D2:Bold.HDV  on SD DISK][ Plus

2) Boot with your APPLE II

3) Will run a game and Stop it with CTRL+Reset

4) ]RUN SD  

... You will see DISK booting.. or goto 3) again.

 

Below video is old time recorded with normal speed on APMSX.

To see this, After MSXDOS boot, You need to run 'A>DEMO ' on the given image.

Enjoy it.

 

Thanks

A2Z80카드의 메모리 맵핑 기능을 활용하여 512KB영역을 사용하는 방법입니다.

 

A2Z80 카드는 내장된 512KBAPPLE //e에서 R/W할수 있는 기능을 제공합니다.

간단하게 32KB 16KB씩메인 메모리의 주소에 맵핑시켜 사용 가능하며,

주소는 $1000~$4FFF 16KB영역, $5000~$8FFF까지 16KB씩맵핑도 가능합니다.

32KB로 맵핑하면 한번에 32KB씩 사용할 수 있습니다.

 

이를 위한 방법을 순서대로 적어봅니다.

먼저 A2Z80에게 버스를 사용하겠다고 명령을 내립니다. 메모리를 Z80도 사용하므로, 세워서 APPLE //e 전유물로 만듭니다. 물론 Z80은 동작을 정지합니다.

 

아래 표를 보시면 

 

A2Z80이 슬롯1에 있는경우 $C09A이 됩니다.

'1000'  0x08입니다.

여기에 $08을 넣으면 A2Z80카드는 APPLE 이 버스를 사용하도록 허락합니다(편의상 32KB 전부 맵핑으로 설명 합니다)

 

이때부터 APPLE //e $1000~$8FFF까지가A2Z80영역의 512KB 32KB가 연결이 됩니다.

 

그런 후 A2Z80의 메모리를 RW할수있도록 설정해 줘야 합니다.

 

이 동작은 아래 Register를 설정하므로 할수 있습니다.

간단하게 $0F를 넣어주면 됩니다.

A2Z80이 슬롯1에 있는경우는 $C099가 됩니다.

 

그런 후 원하는 512KB의 메모리 뱅크를 선택합니다.

 

$C0nB에서 설정을 하는데, $00~$0F값을 넣으므로써 설정됩니다.

 

 

A2Z80이 슬롯1에 있는경우$C09B 입니다.

 

그러면 $1000~$8FFF영역의 32KB영역의메모리의 사용 준비가 모두 끝났습니다.

바로 해당 영역의 메모리를 R/W하시면 됩니다.

 

사용이 끝난후에는 APPLE //e의 메모리 영역으로 쉽게 돌아올수있습니다.

C0n9 $00을 넣으면Z2Z80 RAM 영역이 OFF됩니다

이렇게 하면 $1000~$8FFF영역이 애플2 기본 메모리로 돌아옵니다.

 

이렇게 16개의 뱅크를 선택하여 총 512KB영역을 사용할 수 있습니다.

 

그외 참고 기능으로 

프로그램이 A2Z80메모리 영역에 있는 경우 메모리 뱅크가 바뀌면 프로그램이 없어지는 문제점이 있으므로, 이럴때는 16KB씩만 맵핑하시거나, 프로그램을A2Z80 메모리 영역에도 복사하여 두면, 문제를 해결할수 있습니다. APPLE //e 메모리에서 A2Z80메모리쪽으로 복사하기 위해서는 A2Z80 카드의메모리를 Write Only로만 켜서 Write 하시면 Read는 애플2에서 Write는 A2Z80쪽으로 기록이 됩니다.

 

VGM Player 512KB는 A2Z80카드의 512KB 메모리를 활용하여 만들었습니다.

APMSX카드도 유사한 기능이 있으므로 APMSX카드용으로도 쉽게 적용이 가능합니다.

 

 

감사합니다.

dBASE II on A2Z80Plus

◆ Z80 Card / 2021. 3. 30. 10:10

I searched dBase II on Internet and could get a dBase 2.4 and I tested on CP/M HDD image.

 

I recalled my old memory and made a simple program to add testing records.

Now it have 45752 records and works fine but, slow.

This dBase program is general one and I transfered it to FDD and copy it to the HDD of SD DISKII plus.

To transfer the program to CP/M..

 

1) Download programs for CP/M

2) Add files for APPLE II image disk by Cpmtools 2.9.

It looks some complicated but works.

cpmarchives.classiccmp.org/cpm/mirrors/www.cpm8680.com/cpmtools/index.htm

 

Cpmtools 2.9 Executables for Windows Users

 

cpmarchives.classiccmp.org

3) Transfer this FDD image to another SD DISKII Plus. (For conveniances I used two SD DISKII Plus)

4) Boot CP/M and Copy files.

PIP C:=E:*.*

 

 

Thanks

 

PS: Maximum records on dBASE II, It looks 6553x records (16bits).

If over this records, dBASE doesn't handle properly.

Anyway, This is one of example it has 65000 records and sized 3.1MB and index file sized 1.3MB. I didn't expected it could handle this size of database. :)

Here is bootable 32MB HDD image with dBASE II (in A:)

nzcm32mb.zip
2.77MB

* SD DISKII Plus need to installed on SLOT#7 and A2Z80Plus was in SLOT#4.

* And to start CP/M, need to press '2'

 

Thanks for reading.

Dear Friends and Customers,


A2Z80PLUS card is a 16MHZ Z80 card, but when using CP/M with a diskette, It looks no better advantage,

(Actually, in the past, there was already has a way to drive by HDD but, I can't make it run to loss of files and data)


For A2Z80PLUS, please see the posts in the link below.

https://quick09.tistory.com/search/a2z80

 

 

However, the value of luxury goods is revealed in the end...


The drive of HDD was restored properly by the following as link.

https://planemo.org/2020/06/18/bootable-cp-m-system-on-the-cffa3000-compact-flash-hd-for-the-apple-ii/?fbclid=IwAR2Pt4k9KS9at_sUYnmBhHIzW3EbO_1mMbqUvCNFxTAEM_oDax1md-31cg


So, I experimented/tested right away.


Insert A2Z80PLUS into slot 1,

After installing SD DISK II PLUS in slot 7, select the corresponding CP/M image and boot

First, PRODOS comes up.

To start CP/M operation


-PCPIBOOT (return)


After a while, the number selection appears. At this time, if you press '2'...


CP/M appears.


Drive is

A: B: C: D: Four are caught.

Since the FREE capacity is checked, it has enough free space as shown below.

Additionally, A clock has a driver but, I haven't been able to determine what kind it is.


From now, we can use CP/M with big spaces.


Enjoy it.

 

32MB PO images are here.

Hi, friends,

 

I've upgraded the VDP 1000plus to VDP MSX plus for A2Z80plus card.

As the naming, now it supports sound on MSX game.

Of cause, The Sega1000 and Colecovision also support as usual.

It could be a replacement of VDP 1000 plus board.

VDP MSX Plus board for A2Z80plus

This board used bigger CPLD and removed some TTL chips and put AY3-8910 for MSX sound.

The S/W show SG/MSX, This is the position for MSX.

 

I've recorded one video for your understanding.

Both games sound doesn't sync as picture, it isn't this board issue, it my  video capture device is strange..

Sorry for this.

 

also game on Colecovision mode.

 

 

You could find it on eBay some weeks later.

 

*VDP board used SRAM instead of DRAM for less heat and less soldering way.

You can find good information here.

https://hackaday.io/project/160851-tms9918-vdp-with-sram-video-memory

 

Mode selector switch still there but, user can change the mode by I/O port.

Hence, SG/MSX mode with Colecovision mode can change by the program.

But mode follows the position of switch unless change mode by I/O port.

 

Thanks

Ian Kim

A2Z80Plus is new Z80 card for APPLE II.


It compatible to PCPI Appli-card and enhanced for VDP-1000plus.

It runs as 16Mhz PCPI Appli-card andmore fast SG1000 / Colecovision game console.

and having many functions you never see even similar one with other Z80 cards.



VDP-1000plus  with joypad for SG1000 and Colecovision game play

  





Also could run MSX BASIC



I'm making manual.

Hope to like it on your APPLE II.


Thanks;

Ian Kim

Hi friends,


PCPI Z80 card is one of Z80 card for CP/M.

This PCPI Z80plus have flexibility and faster Z80 run and have extension port for more fun functions.

It works with VDP Option board which has TMS9918 VDP and Sound chip so could run SEGA and Colecovision games also could use to make own program.


http://quick09.tistory.com/1399


Function testing..


PCPI Z80 Function fully working

Turbo Speed 3.58Mhz, 4Mhz, 8Mhz, 16Mhz working.

VDP Option board working, Tested Sega Games.. other games would work... will test soon.

http://quick09.tistory.com/1400?category=552730




But, this testing verion PCB has Missing one line....

Another fixed version will make soon.


* not tested BUS control on APPLE II side..

It have to test it but, I need 6502 source code for TMS9918 and Sound chip.

If someone have simple 6502 code for TMS9918 testing.. It would be nice demo sample for it.

Anyway, the Address of TMS9918 is same as SEGA1000.

Please help for good sample codes then I could test Z80 BUS devices direct on APPLE II(6502).


Thanks for waiting!

Regards;

Ian kim

    New updated PCB ordered.
    I need a week to test it again!!
    Hope to have good final test version!!

Dear friends,


Here is my second step for Appli-card Z80 with VDP Option board.


What is VDP Option board?

http://quick09.tistory.com/1375?category=552730



It starts to support the VDP Option board with 3.58Mhz Original speed.



Both of game are bigger than 32KB and it was hard to load on Z80 Turbo7 structure.

But, New board could support it without memory conflict problem.

Even Turbo speed support but the VDP chip can't run faster speed..


So, This project just remain turbo step control.

It would support some sort of clocks 3.58Mhz 7.16Mhz and 4Mhz, 8Mhz, 16Mhz...

I want the smooth step switching and VDP support even on high clock speed..


* Loading program is very similar the case of the Z80 Turbo7 card with VDP Option board..


Thank you very much;

Ian Kim

Another PCPI Z80 card

◆ Z80 Card / 2018. 5. 24. 19:21

Dear Friends,


Another Appli-card is building now.

I'm doing firmware job and hope to make it work soon.


This board is simple design and would work with VDP Option board.

Z80 would work 3.58Mhz and 7.16Mhz but will try Maximum speed of CPU.

Please keep watch it. 

Thank you very much... :)

Dear Friends,


I'm working for Z80 board on APPLE //c.


After several things hardware bug fixed, It start to boot CP/M as under.




This board is plug on CPU socket on APPLE //c.

And working as the same as Z80 softcard.

Working stable now.


It need to change some parts to make properly.

The PCB needs change some points...


Anyway, I also will try it for APPLE //c+ and hope to make it run on //c+.

Please wait for another toy on APPLE //c.


Unfortunately, It can't exist with Mockingboard 4c.

I will consider if I could make combined one board (MB4c with Z80 board)


Some weeks later, you could see completed Z80 co-processor board for APPLE //c.


Thanks your watching;

Ian Kim

Dear friends,


I started to make another Z80 processor card for APPLE II.

I have though it since I made the Z80 Turbo7 card.

As you may know, the Z80 Turbo7 card is Z80 softcard compatible one but, when I finished it,

I received some of email, they are want another type of Z80 card, PCPI compatible one.

In fact, I didn't have interest in the PCPI Z80 card cause of I didn't have experience and no child time memory with it.

But, It looks interesting.. cause it works 4Mhz or 6Mhz even faster...

On my study of Softcard, it can't run so fast because of this designed really depend on APPLE II BUS.

But PCPI card doesn't use APPLE II Bus for memory access.

It has different design and method unlike Z80 softcard.

For some weeks study about the PCPI Z80 card, I finally understood how it works.

Now, I finished drawing PCB and ordered.

I will assemble and will test for full functioning PCPI compatible card.

Andmore, I add signal pins for VDP Option board hence finally it would work with the VDP option board so it would work 4Mhz or even faster speed.

I already experienced with TMS9918(VDP) and I'm sure to make it run with faster speed of Z80.

Target Speed of Z80 is depends on the what I could have hence I will try even 16Mhz or more...

And more good thing with this PCPI card.


* User may access the VDP Option board without Z80 co-work, 

It means, 65C02 would handle the VDP and Sound chip direct. It results could have as another Arcade board on APPLE II.


You may see another PCPI compatible card some weeks later..


* Next steps;

In fact this Z80 isn't the final goal.

I will use Z180 processor on this PCPI design and it would work as Z80 and even Z180 function could use on this board and you could expect higher speed.. Maybe 33Mhz would work with this design.

Is it good enough for your Z80 compatible PCPI card?


Please watch what I could complete..



* What is disadvantage of PCPI Z80 card;

Many of people just know advantage of the PCPI Z80 card but, 

They are not know about the weakness of PCPI card.. so, I'm explaining to let them know the truth..

You would interesting about my concern.
Softcard using APPLE II's RAM direct and syncing APPLE II Bus.

Otherwise PCPI card is isolated and using gates to receive/transmit data between 65C02 with Z80.


Softcard Z80 could use direct the APPLE II devices without service call.

Even speaker sound, it could make simply on ASM code even Basic(Just need proper address of device on APPLE II)

Keyboard direct reading or Joystick reading also possible.

Also Peripheral card and 64KB AUX memory also could access even more memory could access by it.

As we know the soft switch on APPLE II, Softcard could handle it.

One of good example is GBASIC.

It could handle the graphic mode on APPLE II. 

If you could do some more, maybe DHGR also possible..


But, PCPI card, can't do all of above or limited possible.

But faster on CP/M works.


So, Which is interesting on your hobby job.

If you are willing to use APPLE II resources, go Softcard Z80 card.

If you are willing to use CP/M enhanced hobby, go to the PCPI Z80 card.

This is my conclusion.

Please don't argue with it we are doing it for fun not for serious job with headaches :)


Enjoy it.



Thank you;

Ian Kim

I would like to inform you I've started for Z80 softcard board for APPLE //c.


It would be sit over the CPU socket on APPLE //c same method as the Mockingboard 4c

(http://quick09.tistory.com/1385)

It would work as you have Z80 softcard slot#4 and could RUN CP/M OS on your APPLE //c.

What is CP/M?  https://en.wikipedia.org/wiki/CP/M 

You could run FORTRAN 80, COBOL 80, dBase II, Turbo Pascal etc..

Mostly for study computer Languages and productivity applications not for games... 


Z80 card for APPLE //e was done as Z80 Turbo7 but, now it will go for APPLE //c.

This board is just prototype board and there are several missing..


Anyway someday, we could have Z80 co-processor board on APPLE //c.


Keep watching.

Hi, Friends,


Here is completed VDP Option board.


Board named as VDP-1000 Plus.

It can run SG-1000 Games and some COLECOVISION Games too.


This board can be put on the CP/M Turbo 7 card as under.

It look little strange but, practical design for neighbor card.


It can be installed as this.


The cable are from left; AV connector, APPLE II Video Input for Auto Switching and Joyport.


Watch some videos. 

Your APPLE II could play Sprite games with VDP-1000puls.


You can find ROM file here.

New PCB arrived.

This board optimized using the VRAM and CPLD for less space.

And added sound chip.


Video automatic switcher applied.

Joystick support for the SG-1000 and the Colecovision.

Mode selection Switch SG-1000 /COLECOVISION

Unfortunately I did some mistake and fixed as below.





The Z80 board connector relocated to right side hence it would be as below.



CP/M Turbo7 Z80 card doesn't soldering a connector so, user can solder for their purpose.


In this case, I soldered pin connector male and female for joint.

But, after connect it both, it consume another slot space and may interfere.

Even move the connector to Right on VDP board.

It still consume some space but, some of small card may be usable.


I hoped the VDP option board in slot7 cause there is no other socket on right side so free of space.

If really don't like this combine, maybe can use short IDE40ping cable could be used.


Here are some more running game on COLECOVISION mode.










Here is a Joypad for game play or input device.



This VDP&Sound option board will work under CP/M hence,

It can be also used to make game or other program under CP/M.

Hope to make good fun software under Turbo pascal or Z80 ASM.



New Option board would be prepared some weeks later.

If you have any concerns, please let me know (quick09@gmail.com) .


Thanks a lot

Added some photos. 

Of course it has sound too.

Hope you like it. :)




































I'm waiting for updated PCB.

New board included for TMS9918 , Sound chip and Joypad port.

So, I can play games. 


As you know, this is not emulator. 

It is real VDP board with sound chip.


Also It works under the CP/M 80.

So, You can even make a game under the CP/M.

I want make some game with this option board.


Thanks;

I have hard time to make it work as the COLECOIVISON game console.

After several tries with hard learning of structure.

I could run it but, some game only.I don't know the reason why it can't play the other ROM.


First, It shows start screen by ROM BIOS.


And tested with ROM data. 

I can find upte 32KB sized ROM data but, This board ccould support up to 24KB not 32KB due to APPLE II structure.

This board also works with the privous SG-1000 joypad but not the same. Anyway internally will change this convertion to play properly.




I remember this game. 

It is very old game.. maybe when I was 11 years old, I did play it but, not good player .

In that time I didn't know what does carnival means.


It looks he is using his invented wheel. :)

It's CongoBongo..


Time pilot.. It is some similar as the arcade game..Anyway It's fun to me.


Oh my poor frog..

Maybe from that time, we have to consider to build alternate ways to avoid  the road kill.




And I'm trying to run other games but, still no idea what is the problem.

It looks memory fault or NMI fail. Anyway there is no ROM.. it means, it could be overwriten by code..

It having some hard to understand the structure of COLECOVISION...


Anyway, This VDP board isn't purpose for GAME emulator.

I'm want to show what this VDP board could do. but, It is a board for GAME play too.

Please don't forget it is a daughter board of the CP/M card. :)

And enjoy some game when you are tired while you are making your own program.


Thanks

Here is the VDP Daughter for CP/M Turbo7 card.

It can be installed as the below.






After some of address decoding and some signal processing..

It is working as the SG3000 and run some game as under.







Andthen there is some techinical issue.

CP/M tubo7 looks not handle IORQ properly. so, I've updated CP/M turbo7 and added the signal on the CPLD spare pin.

After start run, it looks not stable. 

I'm checking where is the problem came from, CPU, or signal or TTL?

I'm working on it.

Keep watching.. :)



** Solved stability issue.

I fixed it and works stable now.

It keep running more two 24 hours.


I'm considering to put a Sound chip same as SG3000 and Joyport pins..

Then board buyer could play games as the SG3000.

Maybe it would make it more fun..


** Just added Sound chip.



https://youtu.be/krZJV-vf4No


https://youtu.be/IR01BK_a9O4



** Added another interesting picture.


But, don't expect too much.

It doesn't means that I made MSX computer..

The board have different structure unlike MSX and I can't run ROM of MSX.

But, you can make your own coded to make it run on MSX computer and this board too.

This is the maximum ability of this board.


If you want MSX board, please wait some more weeks to complete the board.


Thanks;

Ian Kim


** I've tested another games of SG-3000 and all works.

Some of game may not work properly. 

Please aware it.

Thank you!

I'm considering make a sub board for CP/M Turbo 7 card.


There are some types could be made.....


Sound card

-It would be a good one but, we have mocking board and it is no worthy to make..

too much similar one.

RAM card

-RAM card would be good one for Z80 but, I'm wonder that what application or software could use it.

If not MSX card, it isn't useful...

PIO card

-I personally like to play PIO.. ON/OFF LED.. looks good. 

ON relay and turn ON some of electric device would interesting..

But, it is easy for me... not interesting to me..

Video card

-Video card would be very interesting one. but, it isn't easy for driving...

Sprite card would be used to emulate some of old computer...

And it it possible to use by APPLE ][ not only Z80 board..


Video card would be a good board for CP/M Turbo7.

Ok, Go for a VDP board.

It would be a interesting project and could be used for sprite on APPLE II.

Here is draft board.


I have to order PCB for this..

Keep watching what I'm doing..  :)

It is two types of CP/M OS.


CPM 2.23 for 60KB free memory

CPM60K.nib


CPAM 60K V5.1.1

cpam51a.nib


You can test it on your CPM card.


FDD should located on Slot#6.

CPM card works on Slot#1, Slot#2, Slost#4, Slot#5, Slot#7(Tested on APPLE //e platinum)


If you have any issue please let me know.

Thanks

Dear friends,


I've build PCB for Z80 CP/M card as below.

It is softcard compatible but can run upto 7Mhz.



User switch is for Normal and Turbo 7Mhz speed switching.

It is a prototype and will make better board for commercial purpose.

It works on my IIe and IIGS with limitation.

As you can see, It provide 40pin signals for Z80 DIY purpose.


Even Z80A runs on 7Mhz but, CPU rating changed to 20Mhz version maybe stabler. 


Thanks

Ian Kim
