Hi I finally set up the IIgs Rom3 machine that I bought a while ago. I've replaced the PSU with ReactiveMicro's one.
I installed CFFA3000, UthernetII and 8MB memory card and installed fresh copy of GSOS 6.0.4. But soon I noticed that I would see corruption, in the form of garbage in window icon view (attached screenshot) and icons and file type going missing in list view (or even displaying some corrupt characters in list view - not in the attached photo though).
I initially thought it was a conflict with an extension or control panel, so I installed a fresh copy of base 6.0.4 with nothing else but I am still seeing the error. I tried with 6.0.1 but still same issue. As soon as I mount a few HD images (with CFFA3000) and start opening and closing windows and copying a few files, the issue occurs.
I thought it may be a hardware issue so I removed the Uthernet II and 8MB memory card but I still saw the issue (with just CFFA3000 installed)
Then I thought it may be an issue with onboard memory or ROM, so I ran startup self test but that passed. I also ran IIgs Diagnostic v3.1 and all tests pass as well (ROM, system speed, MMU/IOU/ RAM, video patterns), except for 'serial internal test' not failing but the program crashing time to time. Not sure whether it's significant.
Any idea what may be causing this? Thank you.
