Hello,
I´ve a question about the 64pin ROM SIMM which Apple used in the IIx, IIfx, IIsi, IIcx, IIci and SE/30. Are they interchangeable on these models (even if they have different ROM sizes and some of them are 32-bit clean)? There are ROM SIMMs with different part no. (eg. 341-0655A, 820-0296-B, 630-4339,...) Best (but not original) should be the Mac ROM-inator II, I know 🙂
Thank you. | Posted by: Nixontheknight on 2022-01-20 09:22:03
AFAIK, you can take a iisi rom and put it in an SE/30 to make it 32-bit clean, but I'm not sure about the other ROMs | Posted by: bibilit on 2022-01-20 10:36:50
The II fx Rom will work in the SE/30, boot sequence will be a bit longer with screen artefacts. | Posted by: volvo242gt on 2022-01-20 13:53:23
I used my old IIfx's ROM SIMM in a IIcx that I owned. With the stock ROM chips on the cx board, the machine would throw up a sad Mac error code immediately after the startup chime. The IIfx SIMM turned it into a slightly crippled (no VampireVideo) and slower IIci. Booted up without problems. | Posted by: demik on 2022-01-21 05:16:42
II FDHD, IIx, IIcx and SE/30 are the same ROM, so yes. You can also use others Mac II ROMs with some limitations as mentioned above | Posted by: macintosh2002 on 2022-01-21 06:40:00
Thanks for your feedback, I´ll try that and see how it works | | 1 |
