공지사항

최근에 올라온 글

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.

** 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!

Used clock integrated chip as below.

To activate the clock, I needed modify present board cause need some more control line for it.

Here is the board with clock chip.


To use this clock chip, it isn't easy with general way, finally my trick works to make it run.


Here is the working screen.

As you can see, it works as the No Slot Clock.


User can change time, and date as the same as the No Slot Clock.

But, Now it became Yes Slot Clock. :D


Work as two blocks 128KB.

Still fully compatible as the Saturn 128K. with first block.

And the other three 128KB blocks also ready to use.


I just add Battery holder for data backup for general SRAM(No clock function) chip.



Thanks;

Ian Kim

This card is one of memory card for APPLE II.

It is compatible with the Saturn 128K and more memory can access with new features.




Testing on APPLE //e


Tested on APPLE ][+ and Card in Slot#0

It detected as 128KB RAM card.



RAM Testing by Saturn utility.

No error, perfect!


As the above pictures,

It tested on APPLE //e and APPLE ][+. I don't know who will use it on APPLE IIgs :-)

Works good as the Saturn 128K..

To use the rest space, user have to send POKE command. it's easy to do it.

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..  :)
