Hey, I bought a IIgs Rom 01, about 2 months back now. It was sold as working, and indeed it is, in that I have booted some Infocom games on it, and it did not crash. But I also already own a IIe and IIc, so I wanted the IIgs for GSOS and the GS specific games. It came with a memory expansion card, unpopulated, so the machine had 512kb of ram. I tried to boot the image of GSOS 6.2.2 from my floppy emu, but it simply did not work. The loading screen appears, but the progress bar went nowhere.
So I ordered 30 ram chips from China (local sources only had 1-3 chips and for £4 each.. !) and about 6 weeks later they arrived. I then populated the Ram expansion card, and I had quite a lot of issues getting it to work with 512kb+ on board. Adding 8 chips and setting the jumper to 512kb was fine. But whenever I set it to 1mb and installed the chips it would error. Last night I downloaded the Reactive Micro MegaMemTester and gave it a whirl, and although I could not tell exactly which chips were at fault, it was erroring when adding 1mb. Anyway I swapped chips around and... eventually it showed good. So I left it for 2 hours in a test loop and it never found an issue. So, I now have 1.25mb of RAM, enough to load GSOS yeah!
So I plugged in the FloppyEmu, selected the drive image, and again, it wont boot. It shows the boot screen, and the progress bar, which never fills and after about 30 seconds it makes a beep like its seeking the floppy and thats it. No good. So I got ahold of GSPort, and I used the SAME drive image on it, in its hard disk slot, and it boots into GSOS. So, it appears the image is fine, and it loads OK in an emulator. But in my real IIgs, nada.I have to say, Im frustrated. Two months in as an owner, and its no different to me than a IIe or IIc, I cant really make use of the IIgs specific OS or games. So, some questions...
1. What exactly do you need to get GSOS to run on a IIgs, do you need a specific ROM, a certain amount of memory?
2. If I DO have the required ROM and memory, why does GSOS still not boot? I have read that mem errors can cause this, but the test indicates the ram expansion is good, so?
As an aside, when I ordered the ram chips, I also ordered a GGLabs RAMGS 4MB card. And that is due to arrive in the next few days. If I plug that in, and STILL cannot boot into GSOS, then I will have to assume there is something deeper wrong with my IIgs.
Any help most appreciated ;)
