I recently found an Apple //c that was given to me by somebody a while ago and I've been trying to check it out. I opened it up for a cleaning and lo and behold I find it has a fully populated AE Z-Ram Ultra III(1 MB) installed. Interesting! Now, back in the day I had owned an Apple //e and a //GS(amongst others) but I had sold all my software when I sold those systems, but searching through the storage shed I found copies of a ton of my old Apple software. So I pop in DOS 3.3 and the //c boots right up. It also passes it's built in system check which I guess means the 128K RAM is good? I try a few old games and everything seems to work OK!
But then I tried some ProDOS based disks and not so good. Most of them seem to load, they show the ProDOS version and what not, but end with "INSERT SYSTEM DISK AND RESTART -ERR 01" or sometimes "...-ERR 02" and I have no idea what that means. Could this be related to the Z-RAM card causing problems? I don't have nor do I know where to get copies of the software for the Z-Ram card which I believe included a ram testing utility but I do know that when I boot a copy of Locksmith 6.0 and I did a FastRamCopy it showed the additional 1024K of aux RAM. I think this may be related to a problem with ADTPro where it will download to the //c just fine but it will not run, it just hangs.
Anyways, I thought about removing the Z-Ram card since I probably won't be needing it, and I'm sure the on-board battery is toast. I guess these Z-Ram boards are still desired by some people so I could sell it I suppose but I'm afraid I'll boink something up getting it out and then nothing will work. Also, I had a few CP/M programs on disk and those would not boot either and the Z-Ram has a Z-80 on board I think so there's that too.
Sorry for the rambling, but if anyone has any ideas or maybe somewhere I could get copies of the AE software utilities for the Z-Ram Ultra 3 it would be most appreciated!
