  1. 2017.05.12 Hyperion 512K RAM+ card
  2. 2017.05.02 Daughter board started work as COLECOVISION but,

Dear friends,


This is final testing board of the 512K RAM card for APPLE II series,






It is fully compatible  Saturn 128K RAM card and even 512KB it have with battery backup so, all data isn't volatile.

And it has integrated No Slot Clock real time clock for APPLE II.

You can use replace old 16KB memory card.

Also You can use it as 4 RAM DISKs with battery backup.



For APPLE ][ / ][+

; If you install it on SLOT#0, You can at least use it as you have +16KB memory card but it is saturn 128KB.

No Slot Clock doesn't work if you put it on SLOT#0.

No Slot Clock emulation need a slot signal and the slot#0 doen'st have it.

But, If you want modify it it is possible.. Please ask me anyway you need a dummy card..


For APPLE //e

You can use it as you have a Saturn 128KB and Real time clock(No Slot Clock ).


* Memory capacity is 4 times 128KB of Saturn hence you can switch present bank with one POKE command.

WIth this command, you can have 4 RAM non volatile DISK with internal battery backup and external battery also provide.


Too complicated?, just use it as the Saturn 128K RAM card and the real time clock 


Thank you

Ian kim

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

Ian Kim
