This image doesn't have ROM images and user need to mergy files on HDV but, not hard to make it.

And there are source code of the launcer.

It tested and works!

 

Thanks ballmerpeak,

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 customers and friends,
 
This version of firmware  fixed some bugs on FDD mode.
Please update your SD DISK][plus with this firmware.
 
What's changed in this firmware is,
 
1) Fixed an error what some images could not start up well at once during FDD booting.
 
2) NODSK??.NIB that automatically creates when formatting without selecting a disk and  now this temporary file automatically inserted during Power ON Boot. 
If I have multiple temporary files, I had a little difficulties to find which was that.

But now, It is more convenient for FDD work for copying a real DISKETTE to image file.

3) Write FDD and then rebooting soon, It desn't updated the image file.
Now it fixed and correctly update the FDD(*.NIB) image file.


Please refer to the link below for how to update the firmware.

Dear friends and customers,


I glad to annouce this information about the mockingboard for APPLE //c+ is completed.

This board could be installed over the CPU socket same and speaker volume also works as followd the volume control slide.

It was fully tested on APPLE //c+ and works great but, on 4Mhz, It generate higher tone and faster sound. For proper sound, you have to set on normal speed on APPLE //c+.

 

I ordered PCB for commercial boards and parts. it would take around 2 weeks and then I could start to ship to you.

 

** Pre-Order will be closed on 28th March **

 

 

Included items;

 

1) MB4c+ board 
2) Two speakers
3) Volume control wire

*It doesn't include 3.5mm AUX cable.

**MB4C+ is compatible with APPLE //c & APPLE //c+

 

Price; $125

(Preorder closed)

For pre-orders, I will ship it for free but only for below countries.

 

* Shipping Issues *

Thesedays, I'm having difficulties to ship world wide.
In this time, I can ship only those countries for free of charge.


--Free shipping countries--
USA
GERMANY
UNITED KINGDOM
LUXEMBOURG
ITALY
RUSSIAN FEDERATION
MALAYSIA
VIETNAM
CHINA
THAILAND
CANADA
PHILIPPINES
HONG KONG(CHINA)
BHUTAN
SANMARINO
ALBANIA

 

For other countries, I have to check if it could be shipped by EMS or UPS and costs would be higher so,  it wouldn't be a free shipping and need additional costs.

For this, Please let me know by email with your address to check the shipping costs.

 

Thanks a lot

Ian Kim

For long time, I used this PS2 Keyboard adapter for my APPLE //e and there was no inconvenices.


And  Yesterday, I obtain a MINI keyboard adapter.
It is quite simple and looks good for small table for testing.


It worked with this PS2 adapter but, I found a issue.

PS2 Keybaord adapter was developed for full sized keyboard and there is 10keys pad is on right side.
And adapter always the Num lock ON. it was OK with it. 
but for this mini keyboard is using this 10keys are overlayed over the alphabet area. It became a problem here.
I can't key-in properly cause the num lock always ON and it send numbers insted alphabet..

 

'PS2 Keyboard Adapter didn't be designed to OFF the Num lock.'

I started to update firmware to handle Num Lock and now, I can OFF and ON.
And It can save as Power Default.
So, now It can ON or OFF Num lock when Power ON.

And Bonus function, Also Caps Lock also can save for Power ON default.

Unfortunatelly, This firmware coudn't be updated by remote so, only future ordered items would be apply this function. sorry for this.

If user could send the board to me, I could update firmware for free but, shipping costs is the matter.

Thanks
Ian Kim

Dear customers and friends,

 

About three weeks ago I suddenly had terrible pain on my back.
First day, I had pain but, I could standup and can do limitted move but, the second day, I even can't standup..
What happend on my body.
I lied on the bed whole days and night.
I don't want to go to hospital just lied on bed.. maybe I'm idiot.
My wife asked to go hospital by the emergency emblance.
But, I think it doens't needed.. I just need to rest.
I searched internet and I guess it is a type of Disk proble on my backbone..
I want rest..
During long months I couldn't have proper rest. almost of everyday I spent time only for developing on new products.
When I hang on some point, I can't go ahead for other things.
Maybe it is my style.

It took about a week to walk again with rely on the walking stick.
Still had pain on my back and right leg.
Now passed three weeks and I could walk without the walking stick.
I can't run but, can walk..
My age is now above 50 and I'm not young anymore.. My body doens't good as before.
Now, I started to consider to keep my health.

My develpment wan't easy. because all products before to develop, it required the understanding about the functions. I didn't make any things just copy from old device. Copy from old one and sell it, it could be much easier but, can't have knowledge from developer and this device doesn't make me feel as I developed, It is just one of copyed device andmore can't put unique fun functions.

From this week, I could move much better. I must not carry any heavy things but, I can do soldering for my customers and could go to post office to ship the good for my customers.

Sorry for delays on orders, I hardly soldered for orders but I feel much better now.

 

Thanks for your support and keep healthy.

Best Regards;
Ian Kim

Dear customers and friends,

 

Today, the A2 OverDrive card works well with the CFFA3000.

I spent a lot of time trying to solve this problem,

As I expected, there was a slight difference in the SYNC timing with the board.


Now, it works well and I have to test the compatibility between APPLE II models,

 

WAV Player currently works only on SD DISKII Plus.


If I have enough time, I could program a WAV player for CFFA 3000.


WAV Player is a simple ASM code, and source code will be released for purchasers and game developers to use.

A2 OverDrive card will be released at a good price for APPLE II enthusiasts and it could help your APPLE II computer runs faster and more fun to use.

 

Thanks for your waiting.

Regards;

Ian Kim

    A2 OverDrive card is revised for compatibility.
    I ordered newer PCB for testing.
    It could be a final testing version.
    If it works nice I could prepare commercial version.
    Thanks for your waiting.

It was long years have passed since I develope the MB4c.
First time, I really want to have Mockingboard for my APPLE IIc and finally could have Mockingboard for //c computer.
it was really happy experianced and It was enough for me.
And revised some version for perfect compatibility as now.
But, the Mockingboard doesn't work on APPLE //c+.
Physically and logically it doesn't support APPLE //c+.
I received some of email who want to have Mockingboard for his APPLE //c+ and finally I promised to finished it.
Infact, When I develped the MB4c, I also tried to make it run on APPLE //c+ but failed.
APPLE //c+ has own cache for faster run and it working different with  APPLE //c.
Some of friends want a Mockingboard with a memory board.
But, It woudn't be easy due to low space.

Anyway, This is a beginning for APPLE //c+ so let me to complete the Mockingboard for C+ first and consider next step on next version.

Thanks;
Ian Kim

    Mockingboard is working and I'm waiting for next testing PCB.



Dear customers,

 

SD DISK II Plus firmware upgraded to V2.73E

1) This version support another HDD access mode (Named as a Superblock) and it is a preparation for A2 OverDrive WAV Player. APPLE can read up to 512MB by ASM driver calling.

Anyway, Prodos can't recognize it, and only 32MB is the biggest capacity on each Drive.

 

2) PO FDD selected and Power ON boot failed to load it and fixed now

It happed when *.PO files selected and power OFF --> ON, but, didn't show it to load.

It fixed now

 

3) Cache access timing optimized, For more speed on Cache, I added some NOP internally on program code and I removed one of NOP my last revised Board would work but, some of earlier announced SD DISK II Plus may have a problem, Please verify it if you having some error on HDD mode. If it brings issues, I will add it as before.

 

Please download the firmware and update it for better performance on your SD DISK II Plus.

SDBIOS.ROM
0.11MB

How to update;

 

Please refer to this nice slide show (Thanks Mr. Johnson Lam)

Thanks a lot

Dear Friends and Customers,

 

 

I glad to announce these new features,

A2 OverDrive card can play 22Khz Stereo WAV files.

It has a 7bits INPUT with an AUX socket.

 

Now, sound much clearer and became HIFI sound as the attached video.

I'm very happy with it cause I can listen to nice quality music on APPLE II.

Even making the good sound, still have CPU resources and DISK bandwidth for more.

I hope to make a Music video player but, didn't understand how to convert video and sound for APPLE II system.

 

Anyway, Have a time to watch this Introduction with Music.

Stereo WAV Playing

◆ Accelerator / 2020. 11. 8. 16:29

Dear Friends and Customers,

 

Accelerator card name change to 'A2 OverDrive'

And built a revised PCB,  Add an AUX port with one more 8bits Digital output.

 

It can play Stereo 16Khz 8bits Way music as under.

 

I also tested to a minimized sound buffer.

Tested 12KB->8KB->4KB all size of buffer working without problem.

 

16Khz Sampling music is good to my ear.

Thank you for watching it.
