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
