Hi friends,

 

I'm glad to announce this news of APMSX card.

I've updated Driver of SD DISKII plus and it boots the MSXDOS as the under.

APMSX boots the MSXDOS

Also runs very nice demo on FDD image.

If start on Turbo mode.. 

It became faster as this.

APMSX card introduction

◆ APMSX / 2019.05.22 19:06

Dear friends,

 

Please refer the attachment for APMSX card.

I just make an introduction for APMSX card and you can know what it can do.

 

After Load BIOS, it will change to MSX computer and APPLE //e still work as nothing happened.

Video output, Keyboard and Joypad are provided separately for APMSX card.

 

I'm making this board for local friends,

After finished, I will put the APMSX card on eBay.

2.33MB

Thanks a lot,

Ian Kim

 

 

** ORDER Closed **  ;( To customers, Please wait for your board. I'm making as promised. Thanks a lot)

 

If you are interested in APMSX, please give me an order(Order closed).

It would take 3 weeks from now(May 22) cause I need to make boards for the pre-orders.

It is a complicated board and I'm soldering by myself so, taking some more time.

Your order can be completed after paid it.

 

Order includes

 

1) Card only;

One APMSX card

One DB9 connector for Joystick

One 4Pin connector for Video IN

+ Two *.HDV image files, PRODOS with MSX image for testing thru Email.

+ Full user's manual of APMSX

 

2) + Joypad

1 Joypad with cable

 

* I can make 1 more board only.

Please order if you want it.

 

** To access APMSX card, it is recommended to use the HDV(32MB) file,

If no HDD emulator , You still can use it with FDD but, it would take time to load and you need to convert files for DISKETTEs.

 

All orders will ship by the registered package. it would take around 2+ weeks.

 

 

Thanks a lot.

Ian Kim

 

** If used two monitors, it can work as below 

Left is APPLE //e screen and right is MSX screen.

Both can work at the same time.

Star Sprite card

◆ APMSX / 2019.04.26 12:46

It was a very nice TMS9918 and AY3-8913 card for APPLE II.

It used TMS9918 and AY3 8912 for sound generation.

It has similar chip as the APMSX and if do match the I/O address, it also would work on APMSX.

 

 

Here are DISK images.

Really appreciated this images converting for share.

 

APMSX I/O address is following MSX I/O address hence, TMS9918 occupied at $Cn99 and $Cn99.

Sound chip sit on $CnA0 and $CnA1

I didn't try it yet but, I'm sure it could make it work on APMSX.

And Basic program looks nice, it can easily use TMS9918 and Sound by '&' command extension.

I will check how to modify it.

 

Thanks

Dear friends,

 

APMSX is completed and commercial gold plated board will be ordered.

It is a real Z80 8bits computer, it isn't software emulator nor H/W emulator.

The CPLD chips used to optimize the amounts of TTL chips.

It works with powerful DMA with APPLE II and MSX mode.

 

Here is the latest APMSX card.

Final PCB

Specifications

Name of the card;  APMSX V1.23a

MSX1 compatible;

What is MSX? please refer here https://en.wikipedia.org/wiki/MSX

Games for fun; https://www.youtube.com/results?search_query=MSX1+games

VDP; TMS9918 (NTSC)

PSG; AY3-8910

RAM; 512KB SRAM

Z80 Clock speed; 3.58Mhz, 7.16Mhz, 4Mhz, 8Mhz, 16Mhz(Overclocked)

RAM Mapper support; 256KB MAX

Mega ROM mapper support; 256KB MAX, Konami, ASCII 8K, ASCII 16K

Keyboard; 1 PS2 Keyboard port

Joystick; 1 MSX DB9 standard port

 

Compatible APPLE II

APPLE //e recommended, Full functioning.

APPLE IIGS; It has some limitation on dual working with APMSX, limited on Memory card access,  But, General running MSX games or programming doesn't have a problem on Apple IIGS.

 

How to use it

(1) Use as an MSX computer

Joystick support and Keyboard even Video output exist.

Please refer to the history of APMSX.

https://quick09.tistory.com/category/%E2%97%86%20APMSX

 

(2) Z80 Softcard compatible; CP/M 80 operation.

 

(3) APPLE II can access whole 512KB Memory area even I/O while APMSX running Games (Of course, it needs BUS DMA)

MSX IO Ports mapped on $Cn00 hence, APMSX could be used as a VDP card or Sound card similar to the Arcade board.

APPLE II can use 512KB memory area on $1000-8FFF so, can use as an extra Memory card.

 

(4) Use Z80CPU for APPLE II as Co-processor as a Graphics accelerator or sound processor.

Z80 could access APPLE II area hance can access HGR and speaker.

if 6502 give order function such as graphics, ie circle, paint or scroll then Z80 could calculate and run background for the graphics or sound. It is one idea to use Z80 area and you need programming for it.

 

Recommended APPLE II

APPLE //e + SD DISKII plus DISK emulator

32MB HDD emulation is good for APMSX with lots of ROM images.

Even one FDD can use but, not many games could put in a DISK.

APPLE IIGS works but, no full duplex way.

Not working on APPLE ][ nor ][+

 

Planned Production release

About 14days later

 

Order now

Pre-order would receive a free Joypad ($15)

Pre-order closed now.

 

All packaged would be shipped by Registered package with a tracking number and it would take two weeks once it shipped.

 

If you are not sure now, You may buy it on eBay some weeks later but, the price would higher(+10%) for eBay fee.

 

User's Manual

On Working.

 

*********************************************************************************************************This APMSX card is a real and true 8bit MSX computer and successfully connected on APPLE II.

It took a long time to develop and it was one of my dream machines.

Runs 16Mhz Z80 and there is no MSX had this speed with smooth VDP access.

And it can share APPLE II resources so, it's a peripheral for APPLE II and can share APMSX resources each other.

it isn't just a standalone isolated MSX computer. It can communicate to APPLE II on BUS level.

Hope you like this card.

Have fun with this card with your Apple II.

Other systems such as commodore or spectrum etc on APPLE II...

Hope to see someone make it for APPLE II.

 

Thank you very much;

Ian Kim
