| Radius SE Accelerator 16 ROM dumps |
Posted by: rsolberg on 2019-07-17 17:23:12
This post probably could have gone into Compact Macs or Peripherals, but programming EPROMs seems more hacky. I have a lovely Radius SE Accelerator (16MHz 68020 and 68881) in my SE FDHD and it's got ROM v 1.8 with a date of 1987. It works mostly okay, but I suspect the Radius ROM isn't totally compatible with System 6 or the SE FDHD's ROM. So far, any version of the Radius software I've tried fails. Older software seems to balk at System 6 and refuse to run, newer software tends to just crash spectacularly on load. Does anybody have or know where I can find the 3.0 ROM dumps for this card?

Do you have the init installed? I one of these, I wonder if there's a way to download the roms without opening the machine,

The inits I've tried definitely break things badly. I suspect that the ROMs are inaccessible via software as the Radius documentation indicates you need to send the accelerator to them or replace the PROMs to upgrade.

Are you sure there is a ROM 3.0 for the Radius Accelerator 16 for the SE? I can’t remember my source for this (sorry) but my strong recollection is that the Plus and SE accelerators had different ROMs, and only the Plus accelerator ROMs ever got up to version 3.0.

I think the Readme file from this floppy image may list all the version numbers. I can’t access it right now or I would check for you. http://macintoshgarden.org/apps/radiusware-1990-displays-41-accelerator-29-radiusmath-15

Found my reference. See link below. Per whenever this was published at least, the latest version of the Accelerator 16 SE ROM was 2.1 (still never than what you have) which should work with systems up to 7.1. It sounds like older ROMs were known not to be System 7 compatible at all.
ROM version 3.0 was for the Plus accelerator only, I had one until recently and can confirm it worked great with System 6.0.8 and 7.0.1.

Doh! Yup, ROM 2.1 is what I'm after. I misread the readme before my original post.

Hello!
I would need the 3.0 rom file for Macintosh Plus. Does anyone have one? It would be very important because mine is bad🙁 |
