Repackaging the SIMM ROM types in DIPs is no doubt achievable but you need a lot of motivation to try it. Trag knows about repackaging soldered ROMs as SIMMs from his work on the I…

software patching cannot handle everything. If it could, the 512K could boot directly from an HD20. Click to expand... No it couldn't... it would have to boot from a floppy to …

... I'm surprised though you've not been able to find the cache cards - seemingly a leisurely trip in local hard rubbish would reveal a slew of 486 and Pentium 1 machines with the …

Very nice. As for the WGS 95 card...I'm fairly sure that you actually need A/UX in order for it to work. It'll run with 7.01 or 7.1 installed...but I don't think it'll actually …

Do you know what shadows lurk in the hearts of men? You've been tagged by Equill. You are going down.

... It also came with a Workgroup Server 95 card which apparently doesn't work (hope not), but the cache slots are all filled (512K?). No idea on RAM, HD or WGS95 status yet until …

A smaller fan makes a Q950 a much better neighbour. As long as you don't stuff it full of Nubus cards and drives, it works fine with a smaller fan and without the wind tunnel produ…

Why do you think the PDS card does not work? It is made for A/UX only and while it will boot in OS 7.01 (wont work but the machine will boot), newer mac OS versions tend to hang/cr…

Very nice! :O Sounds like a good score....I'd quite happily pay $56 for such a beast.

Hi all, picked up a Mac on eBay I've never seen in the flesh before: a Quadra 950, lovely condition and should come up well with a strip down and blast with my air compressor. Co…

lord knows by that time they had gotten enough ROMs wrong the first time around Click to expand... Did they? The architecture was designed to support software patching. Clic…

The IIx has been called a SE/30 stuck in a mac II case. Click to expand... Hm, where did the screen go? Have you noticed how a Mac II case is exactly like the bottom half of t…

Why on Earth they would have soldered the ROMs in place on any machine is beyond me Click to expand... It's cheaper lord knows by that time they had gotten enough ROMs w…

I think that there is some confusion here....Note the four socketed DIPs next to the SIMM sockets. We can assume that the IIx layout is similar, because the ROMs were sold as an of…

I think that there is some confusion here. The early Mac models have ROMs that are in a DIP package. Examples: 128K/512K, 512Ke/Plus, SE and SE FD/HD. Later Macs (SE/30 and IIfx) …

you also need System 6.0.2 or higher lest the Macintosh II still mistake the high-density drive as an 800kB mechanism. Click to expand... Yes I read that and was surprised cons…

Yeah, as a part of the Mac II FDHD upgrade you do need IIx ROMs. I don't think the SWIM controller will fully function without it, as the Mac II ROMs most likely don't have the rig…

I'm not really concerned, I won't be using OSX with it much at all. Thanks for the info though, kind of a shame to think OSX makes so many invisible files.

Also formatting floppies in OS X is a bit hit-and-miss. It won't do the part where it goes back and eliminates bad blocks. You also don't get the 100% same full capacity for some…

I believe the SE/30, and IIx ROMs are identical. Since the Mac II can be upgraded to FDHD, does that also upgrade it to the IIx ROM? I know the SE/30 can use a IIfx and IIsi ROM.…
