Hyperion 512K RAM+ card (V1.22)
It is compatible with the Saturn 128K memory card and the No Slot Clock.
I developed it for my APPLE ][+, Cause I needed a16K language card for 64KB full memory.
The structure of Saturn 128K memory card, It is compatible with 16K Language card and It is very good for APPLE ][ and ][+ which has only 48KB RAM and need to add +16KB andmore it support +128KB total memory.
As you know, Saturn memory card has own memory address so user could put program and run with switchable banks.
Hyperion 512K RAM+ card is fully compatible with the Saturn 128K and NSC clock.
And added memory space side is 512KB, it works as 4 sets of Saturn 128KB.
It has a non-volatile memory 512KB to keep data even APPLE II power off.
It is useful for pseudo disk and user could switch 4 disks by simple ']POKE 'command.
Due to no APPLE II has real-time clock, this card work as has a No slot clock.
*It needs slot signal and need a slot so it should be called as 'Yes Slot Card' not No Slot Clock :)
*No Slot Clock function doesn't work in Slot#0 but, Saturn 128K works Slot#0
If you want to use an general Saturn card on APPLE //e, Saturn card less useful.
But, Clock would be more useful on APPLE //e or APPLE ][+.
