이안은 뭐하니?

Hi, Everyone,

My selling products are mostly in the eBay but, the price isn't the same as my sales price in here.

Because eBay taking service fee, If you want to order direct you can get discounts as I advertised.

If you want to Buy it, Please ask the stock status even if not on eBay. 

(Some item have limited small quantity)

Thanks you.

Dear Friends,

If you have difficulty to use Smartport HDD on your APPLE IIGS,

Please try it after Unload D1: or 'Your card' of SLOT6 on IIGS control panel.

If some image file in D1 for autoboot, some cases failed to detect Smart devices.

I'm working on it.

* Tested *

My connector got faulty not the firmware.

Anyway, you can use the latest firmware.

Thank you.

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

Hi friends,

It is a ZAXXON game with mockingboard 4c support.

You can only find here in my blog and cause I did crack it to make it run on APPLE IIc.

Enjoy it :)

Dear Friends,

I added video switching function for MSX card.

It looks better for one monitor user.

Anyway, User still can use dual monitor for APPLE II and MSX card.

Dear customers,

I updated firmware for SD Smart Drive.

New version is V1.18R and fixed some minor bugs and enhanced to detect Smart device on APPLE IIGS.

Please download it and update for your Smart Drive.

Version 1.18S

SDSmart.ROM

How to update

History of V1.18S

-'No file' error message shows the reason.

-Smartport detection method changed for APPLE IIGS.

Before some of cases, failed to detected on IIGS. 

It was happened when power ON FDD boot and Smartport drive status requests.

It doesn't affect on IIc and not works good.

History of V1.18R

- Enhanced the SD Smart Drive detection on APPLE IIGS.

- Locked FDD file showing on the Terminal when Loading it.

History of V1.18Q

- RAM test method changed and it doesn't destroy present data in buffer.

- Serial recovery changed for better recovery to 115200bps.

Dear friends,

I put two movies which are showing the MSX card running on APPLE IIe.

First movie is showing the switching between APPLE to MSX by command and even running together.

This mode provide data interchange between APPLE to MSX card.

It is shareing the SLOT0 of MSX memory with APPLE IIe main memory.

And MSX card can access even APPLE II device.

On the beginning movie, You may find It is using HDD for program loading on MSX card.

It can R/W access on the SD DISK][ Emulator card (HDD mode).

When MSX card access APPLE II memory, The APPLE Speed lower to avoid memory access conflict and

about 1/3 Mhz is the running speed of APPLE IIe in that time.

MSX card works around 2Mhz for synconise with the APPLE II BUS.

Anyway watch it.

If you install the DISK II Emulator on your APPLE IIGS, 

You have to adjust slot configuration to 'your card'.

This is the best manual for APPLE IIGS users.

If you need to slot setup on your IIGS, 

Please refer the below and the given links for more information about APPLE IIGS.

Thanks

		Do not press 3 unless you are operating your Apple IIGS in a country where the standard signal frequency for monitors Is 50 hertz. If you choose the wrong hertz setting. the Image on your monitor will roll or be out of alignment. To restore the standard U.S. settings, press Option-Control-Reset. Then press 2.

Dear friends,

The Mockingboard 4c is only the soundcard that you can find for your APPLE IIc.

Now, the Frech touch team has started to support MB 4c on their great music.

Please download the Pure noise or just get this NIB image file.

Thanks for the great work on mockingboard.

Z80 MSX is Z80 CPU board and have devices as the MSX computer.

It can run under the APPLE IIe but, it isn't just running one computer with shared Power supply of APPLE IIe.

It isn't just one isolated system running above the APPLE IIe. It is running inthe APPLE IIe with shared memory and running together with APPLE IIe.

The both of CPUs could run at the same time.

The structure looks like as under.

As you've seen, MSX hold all area of APPLE IIe so, all of APPLE IIe memory could use.

It means that even I/O could access by Z80.

Z80 MSX board have two major modes.

Single running mode

Single mode, runs only one CPU and the other one is waiting unless give ticket to run.

Mode 1;  Z80 running 2Mhz but can access all of APPLE II Memory area

Mode 2;  Z80 running 3.58Mhz and not access APPLE II memory area

* In fact, Z80 has 512KB own memory and using APPLE IIe memory as extra one. So, when It running on the APPLE IIe memory, It can't run more than 2Mhz so, Z80 only runs 2Mhz on APPLE IIe memory.

But, if it runs on it's own RAM, it could run full speed of MSX (3.58Mhz). 

It automatically change the clocks.

Dual running Mode

Always working both of CPUs but CPU speed isn't fixed.

Mode 1; Z80 runs 2Mhz when it runs on APPLE IIe RAM and 65C02 runs about 1/3 Mhz.

Mode 2; Z80 runs 3.58Mhz when it runs on it's own RAM and 65C02 runs full speed 1Mhz.

* Dual mode always 65C02 is running.

The 65C02 runs with variable speed. When Z80 access APPLE IIe memory, 65C02 runs only around 30% but, 65C02 speed is variable not fixed, 

If Z80 didn't access APPLE IIe Memorh BUS, 65C02 could have more clocks to run. 

When Z80 using own memory, 65C02 is free to use all of bandwidth of BUS so could run 100% of speed.

So the 65C02 speed is vary 30% to 100%.

With this feature, You can use Z80 CPU as the co-processor vice versa.

While the Z80 is running, 65C02 still have clocks and no need to wait for Z80 done.

If you don't want share APPLE IIe memory, you can consider to put Z80 codes into Z80 RAM area to make it run faster. Anyway, It required proper code to switching Z80 memory and APPLE IIe memory.

Z80 MSX card can use all of APPLE IIe resources

In fact, the time critical equipment can't use properly. such as Floppy DISK Z80 may lose the data from DISK.

To use DISK, should switching or Should allow to RUN 100% of 65C02.

Z80 could approach all area of APPLE IIe, I mapped it to SLOT#0 of MSX.

Even could access graphics mode, Low and High Res. modes and APPLE IIe speaker can toggle by Z80.

Andmore other peripheral device could access but not interrupt device.

You can select starting mode between Single running mode or Dual running mode for your purpose.

Even after RUN, if the memory condition is fine to change the mode, you can switch to another mode too.

Z80 make 65C02 to run or wait. vice versa.

I want to use this feature to access APPLE IIe HDD for Z80 MSX.

Also I want to use the Z80 MSX card as a Arcade board to display sprites or play songs.

Of cause,  add some code for Z80 it would easier to use complex command such as draw circle or any on Back ground.

I just provide the potential possibility for user who love Z80 MSX and 65C02 APPLE II.

I would be happy if someone could make interesting game or tricky programming with DSP and PSG.

Just wait for some more weeks to to complete the design.

Thank you

Now Z80 MSX card runs on 3.58Mhz as well.

But, I would like to test if it could run above the 3.58Mhz.

Now, I've tested it the 7Mhz, It is exactly 2 time clock of the MSX1.

WOW,

It's running.

The ticks just 42 now, (Original MSX takes 88)

But, It failed running GAME ROM.

I guess VDP failed to run on the 7Mhz.

So, I slight slow down it to 5Mhz.

It runs and took 60ticks but lessthan 88 ticsk.

Tested Game ROM too,

It works but, failing some sprite display.

I think that it is really fail to run VDP.

I want to make 4Mhz but, can't do it with APPLE II clock.

Someday will test with 4Mhz.

Maybe 4Mhz will run fine.

I'm testing 3.58Mhz MSX running mode but, even slight faster would be better than just normal as the MSX1.

Thanks

Hi everyone,

Z80 card speed didn't reach to 3.58Mhz original MSX.

The Z80 MSX card runs as based on the architecture of the Softcard and it runs 2.045Mhz.

This speed limit is due to the APPLE II BUS speed and Z80 internal structure.

But, I tryied to break the limitation of 2Mhz.

Anyway this is one small BASIC program to determine the system speed.

(Low numbers is faster. (60hz tick) )

It took 88 ticks.

My Z80 MSX card runs as below

(I'm calling it 2Mhz)

Looks very slow?

In fact, while running games, I didn't feel slow as the number says.

Most of games doesn't use loop timer, and they are used 60hz VDP interrupts.

So, It almost same speed on many of games.

And now, I want to make it faster. But, How?

Z80 card have a 512KB SRAM and decide to run the Z80 when it doesn't use APPLE II BUS but using only SRAM.

I tryied several times and finally got the result.

Let's run same BASIC to check speed.

Hmm.. Just little faster..  (I calling it 2Mhz+)

What's wrong?

In fact, BIOS+BASIC is in the SLOT0 and this area is APPLE IIe location.

And it couldn't run faster in the BUS area.

So, Now, I upload the BIOS+BASIC into the SLOT3(SRAM area) and switch it to use only SRAM by Z80.

Ok!! GOOD. 

It is the same ticks spend as the S/W emulator.

I manually Switch the PAGE of BIOS+BASIC configuration.

And it works can switch to 3.58Mhz from 2Mhz+.

But, failed to switch 3.58Mhz to 2Mhz+ on basic prompt.

I guess that it is due to switching timing while running the memroy.

So, move to Safer location and switch the PAGE0&1.

This small program would help to switch the PAGE configuration of MSX.

The Data is Z80 codes and direct control the SLOT memory configuration.

A0 means Lower nibble is 32KB Slot# and (00 00  00 00 (BIN)) is SLOT#0.

Before I set it AA(10 10 10 10) to use SLOT#3.

And you can see the ticks changed to 146(2Mhz+) from 88(3.58Mhz)

I'm considering to move the BIOS+BASIC to SRAM area not on APPLE II Memory area.

It would be better performance.

Anyway I have a bug(Bus conflict) when I used Multi running. So, I disable to run Z80 and 6502 at the same time.

It should work much better but, the BUS conflict bring something wrong.

I'm trying to solve this technical issue.

Anyway, It runs 3.58Mhz Z80.

Thanks

I've tested more MSX game ROMs.

Alll are working with good sound.

Bosconian

Runs little slow.

A few of games are not working properly cause of Z80 CPU running slower than original MSX speed.

This Z80 CPU card runs 2.045Mhz  so, if games used a S/W loop delay, it would be a slower than Original Game speed. But, Many of games hard to feel the slowness. Maybe interrupt driven used for delay on the games. 

This is good approach and helpful even less or faster CPU system.

And now, I'm tuning it to make better.

Keep watch it How much could I approach for the MSX computer.

Thanks

I've tested below ROM file.

It works fine.

Mostly my favorite games.

I didn't test all games, just some what I liked.

Not all of games works but, many of games could run on the My Z80 card.

This card isn't for running games but, for MSX enjoy.

Hence, I will start for Keyboard emulation for MSX BASIC and other purpose.

Thanks

It start to run MSX Game as the attachment.

Having trouble to watch the video?

Please try here.

Left monitor is for MSX system, Right one is for APPLE IIe.

Now It need two monitors but, I will combine the Video signal hence only need one monitor.

I used SD DISK HDD mode to load MSX BIOS and GAME ROM data into the Z80 Board.

And easy to load ROMBIOS of MSX and Image file of GAME ROM.

The Z80 board have 512KB Internal RAM and Main BIOS RAM area shared with APPLE II main memory.

Other Memory area can remap to 1000H-4FFFH for APPLE II access.

So the results bring easy handling by APPLE II.

It also act as the Softcard. (The Last movie parts) and working properly.

This is a Joypad for MSX Game.

But, I'm considering if it possible to use APPLE II keyboard to Joypad emulation.

Anyway, I will keep going to complete it for me.

Thank you very much.

Z80 card run the MSX BASIC.

But, Still I have to do some more to support SLOT concept of MSX system.

And Keyboard and PSG(Sound chip).

I'm working for the SLOT memory but, It is hard to do now. cause there is no easy memory space for MSX.

Hence I decide to add one SRAM for MSX system.

It  become complex than I expected cause the SLOT memory space really required to run GAME of MSX.

And the SLOT memories having overlapped address on each SLOTs.

So, I'm having difficulties of this.

Anyway I will try to implement this SLOT for my Z80 Card and want to see the running MSX in my APPLE //e.

Thanks

I set the TMS9918 with VRAM and configure the IO Address.

The RAM using of APPLE II one not other one.

I did load the image ROM file by PRODOS and works as below

This board doesn't have RAM so, the ROM image is on the APPLE II RAM.

It is hybrid structure unlike other H/W emulation one.

Even hardware emulation, it can't say hardware emulation cause it has same logic design of the SC3000 and TMS9918 for Video.

Seeing is believing.

Watch it :)

The Z80 run 2Mhz but, it looks not slow running game.

It doesn't have any joystick nor keyboard so, I can't play but, I could see everything without delay.

Anyway, I will move this board for the MSX1 computer.

Someday, I could show running the MSX1 system on my APPLE //e.

Also Tested CPM 3.0 works!

With several Logic update on CPLD, I got finally working softcard.

I tested it and work as 1Mhz and 2Mhz.

My target is 7Mhz Z80 card. it would be very interesting steps.

The softcard used DMA and RDY and Z80 Wait for it's purpose of CPU.

Thanks MS for the idea of Z80 working on 6502 based Computer.

Now, I'm starting to put TMS9918 VDP and trying to make it work.

I hope to show some of working screen soon.

Thanks
