There were apparently several revisions and I'm not sure how many actually got burned to ROM. My GS is a ROM 01 so I don't have any reference except the ROM images on the 'net. All the images I can find appear to be the same one which is referenced as Apple part# 341-0737. One area that had several revisions was the Font Manager. If you guys want to check your real GS's or any ROM 03 images at this memory location to see if other revisions are out there: FC/AAE2: A9 00 03 83 07 4C 82 C1 lda #0300 ;Font Manager version # 3.00 for Apple part# 341-0737 sta 7,s jmp $C182 The Font Manager version in the source is 3.04 If you find any version newer than 3.00 I would be really interested in an image of the ROM for comparison.

When booting into GSOS, there is a key press combination that will show all of the revisions of the Tool sets on the text screen.  I am not sure if they show just the disk based tool sets, or also of the ones built into both ROM 01 & 03.

Maybe someone else can shed some light on that.
