- The Macintosh Do-It-Yourself Upgrade Book I imagine these are pretty rare, apparently they made a bunch of models for B&Ws but also LCs too. Neat!

I had the same problem for awhile. Sadly I can't remember exactly how I fixed it but it involved discarding the guest disk a few times and disabling some extensions on the host. I think it's some extension conflict with the AppleTalk magic the Rocket does to bridge disks.

3.4.1 is the latest I know

I've had good luck just running the latest RadiusWare on 7+.

For some reason it never occurred to me a pico PSU can avoid the power supply connector compatibility issues between boards and cases. Obvious in hindsight, and handy!

Huh, I'm aware of third party patches that add pre-G3 support for PCI Macs, but I think it always requires hacks.

Oooh very nice! My friend has a non-turbo slab I've been wanting to fix up for them... The multiplexor detail is pretty interesting, I wonder how unique that was in 040 designs overall.

AFAIK 9.2 truly removed pre-G3 support.

I have 8.6 in a partition on my Quadra with a PowerPC card. Besides glacial boot times, it honestly doesn't run much worse than 8.1. To get it on there you have to jump through a bunch of hoops with the Sonnet Presto enabler. Not sure that was ever supported for a Iici though. I've read claims...

I've been maintaining a list of these (and others) I need to get around publishing. Here's the logic board ones I know of: 128k - https://github.com/RichCini/MacRedux Plus - MacPlus-Reloaded SE - https://github.com/kr239/Macintosh-SE-Reloaded - Logic Board - Macintosh SE Reloaded - Macintosh SE...

80MHz 040 when??

I was reading through the 68040 designer's handbook tonight and figured I'd share the reference thermals for future overclockers. Motorola's reference heat sink is a Thermalloy 2338B: https://www.farnell.com/datasheets/94193.pdf It's designed around the E-Z Mount which never really gained...

I found a Sony MPF920-1 with a June 2001 date in one of my spare PC cases. It seems popular for Greaseweazel and I can confirm that mine works wonderfully for Mac disks. So it seems even fairly late MPF920s work nicely.

It definitely seems like a much stronger attempt to make it look like they "clean room" engineered the ROM since it has totally unique assets. I think that's also triggering the bug on 4.2+ (5.0+). It seems the "Welcome to Macintosh" screen interferes with their custom splash screen and refuses...

Seems DosFox, who re-shared the ROMs, is way ahead! I found this awesome thread, I highly recommend checking it out: https://tech.lgbt/@DosFox/114053665154970955 I've seen more than a few references to Unitron boards being Plus clones, including DosFox build, which makes things even stranger...

It's interesting that every single ethernet device seems to hold its MAC in the first bytes. I guess it makes sense, no offsets to calculate, and the other alternative, storing it at the end, would interfere with the DeclROM trailer.

Some more notes from today: At least in PCE it refuses to recognize any HFS disks, meaning only 400k disks actually work (I was wrong before). It's definitely less stable than a real 512K ROM. But it does seem to support up to System 4.0/Finder 5.4 just fine. I tried many old shareware titles...

Ah thanks for the reference! Looks like it might require some source modifications as well, as I'm booting it in PCE as a 512K with 1MB memory (since the ROM looks more like an expanded 512K ROM than a Plus ROM). Roughly, that appears to be enough to get things going if anyone else wants to give...

Turns out I'm wrong. After a LOT more fiddling with PCE I got it to boot Finder 1.1, strange mouse icon and all! Why MiSTer won't boot is a....mystery.

A fair bit of information has been spilled about the Unitron 512, a Brazilian clone of the 512K (here's Low End Mac's take: https://lowendmac.com/2016/unitron-mac-512-a-contraband-mac-512k-from-brazil/). Less, however, has been mentioned about the Unitron 1024. Unlike the 512, which seems like...
