IIGS ROM 01 or ROM 03?

I have both a ROM 01 and a ROM 03 IIGS. Which one should I use?

Probably the ROM 3. More onboard memory means that you will have more memory overall. The updated ROM should mean that less of the Toolbox is in RAM too, which is handy.

I think some suggest using ROM 1 machines for games. IIRC, a ROM 1 machine also allows you to put the SCSI card into slot 1 and configure slot 7 for appletalk. Which was useful for some long forgotton reason.

ROM 3 has 1MB built in. I guess it depends on if you are going to run GS/OS from a HD or just want to play games from floppy.

ROM 3 for GS/OS, ROM 1 for floppy based games.

I think I'll go with the ROM 03 for my IIGS setup. I want to get GS/OS running off an HD someday. My ROM 01 has a 1 MB RAM card. I can put that in the ROM 03 and get 2 MB. Then I just need a SCSI card and I'm set.

The SCSI card will be the hard one to find (cheap).

You might want a bigger RAM card for a ram drive.

ROM03 machines have less background noise coming from the speaker. It's most noticeable from within GSOS, where the processor and video hardware stay pretty busy.
