Continuing with the Duel CPU theme... Z80B / 65C816
Z-RAM Ultra 3 for the Apple IIc by Applied Engineering, 1Meg RAM, Z80 CPU, Clock (I have removed the battery).
Its a bit of a bonus when you get three functions on one card to fit inside the very compact design of the IIc
Optional 65C816 16-Bit CPU plugs right into this card without any changes, giving you a 16 bit processor.
This is one of the Z-RAM Series of three cards, Ultra-1, Ultra-2, Ultra-3, the later having all three features,
an Ultra-1 was a RAM upgrade only. Ultra-3 has a High speed Z80b for CP/M
(from an old brochure)
Z-RAM Ultra-3 with 512K RAM $549
Z-RAM Ultra-3 with 1 Meg RAM $849
Optional 65C816 CPU $79
"Make Apple Works run 20-30 times faster"
Five year warranty !
i'm going to assume this card has 512K ? RAM populated, and if all the empty sockets where populated it will have 1 Meg of RAM.
The plan here is to roll without the battery, top up the RAM and install a 65C816 16bit CPU and fit it to
one of my Apple IIc's, that will be one grunty little Apple II that has a carry handle
and is as small as some laptops and not to heavy
It wont keep the real time but I don't
want to open it one day and find acid damage, I don't run batteries in my Apple GS's either,
there just is no real need
