My system setup: RamKeeper - Fully populated Apple 1Meg ram card on the back pocket (tm) GSRam+ connected via the male-to-male connecter. My problem: I used to have 2 Meg on my GSRam+ and I set the RamKeeper to have a 1 Meg ROM disk. That left 2 meg for main memory. I got a few extra bucks and decided to upgrade my system... so I bought 3 more meg. I figured that I could have 4 meg main memory (remaining DMA compatible, eh?) and have a 2 meg ROM disk. So I plug in the chips... and my system doesn't work. That's about the best way to describe it, too. I called up AE and asked for help... they told me to send in my card and they'd take a look at it. Yeah, right... like I'm really gunna work with a 256K machine for a year while the idiots sit it on a shelf and then send it back unchanged telling me they found nothing wrong with it. Now here's the fun part - I set my ROM disk to 3 meg... and my system will boot and behave normally... except that the ROM disk checksum doesn't match. I try copying things to the ROM disk and I get weird GS/OS errors like $8000 and $8052 and such. Thinking that I might have bad chips or something, I ran the GSRam+ memory test program. No errors. In fact, the system works fine without the RamKeeper in and I just use the Ram+. So... any help from you guys? -- ===> Josef W. Wankerl, college student | "I am a Viking" -Y.

I just recently added a RamKeeper and a 2 MB Apricorn card to my system. I was getting errors $8000 and $8051 when I tried to access anything beyond the first 60% of /AEROM. Just on a hunch, I tried switching the cards around (AST RamStakPlus now on the SlotMover; Apricorn on the back side) and everything's been working great since then. Henry >===> Josef W.
