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...

I've been using my Greaseweazel to read 720k and 1.44mb IBM floppies and Amiga 880k floppies successfully, but 800k Mac floppies seem to be failing. Obviously they're GCR which normally causes problems, but if I understand the docs correctly, the flux image is read at sufficient rate you can...

I discovered something interesting while I was looking at the software for the Magellan 040 from this post: https://68kmla.org/bb/index.php?threads/na-2021-ebay-finds-thread.37524/page-179#post-556420 A fair amount of older software was incompatible with the 040's caches. Traditionally this was...

It seems my Quadra 700 is missing it's 4-pin cable for HD power. Does anyone know the pinout? From a picture online I think it's (numbered from bottom left viewed from the cable end): 1 - 12v 2 - Ground 3 - Ground 4 - 5v Which helpfully mirrors the pinout of the other end. Can anyone confirm...

I haven't seen a lot of Mac-on-Amiga topics on here, which is a shame. I've been restoring a 500 and had to give it the ShapeShifter treatment. If you're not familiar, ShapeShifter is the predecessor of both SheepShaver and Basilisk II. Unlike the latter, it's a hardware emulator but not a CPU...

I find I keep running into this problem...when installing network peripherals on 8.1 somehow OpenTransport gets damaged and stops working. Applications report various errors, like "cannot open resolver", claiming too many network connections are open, or just outright failing. AppleTalk works...

So, it's been benchmarked here before that the AsanteFAST 10/100 Ethernet card...just isn't too fast. Unsurprisingly older OT just can't push very quick anyway, and so the returns are really diminished...

I'm trying to understand some parts of the eMac hardware layout, but I don't have one on hand. Does anyone have dumps from any of TattleTech, the LSPCI application, or the Open Firmware device tree? Preferably from the OS 9-compatible eMacs.

No affiliation, just happened to notice this on Tindie today and haven't seen any discussion on here: https://www.tindie.com/products/ymkdevices/synchr030s/ Wild product. Seems like it has a PDS passthrough, so I'm not sure how they tested with accelerator cards. I kinda wonder if this works...

Various FAQs and READMEs from SuperMac indicate the 3.0 firmware for most of their cards (Thunders, many Spectrums) supports dynamic (rebootless) resolution switching. Which is really handy! But that's been curious to me, because it's never worked...Monitors always says a reboot is required, or...

As is inevitable, I have another failing Mac mini optical drive. In this case, a SuperDrive (Matshita UJ-845-C), so pour one out for one of the nicer ones. I'm looking for replacements, but before I'm lame and replace it with an identical drive, I was wondering what alternatives exist. Maybe...

Surprisingly, I didn't see this anywhere searching around the internet even though all the ingredients are there, but maybe I missed it. If you're dual-booting your New World Mac between OS 9 and OS X, you can easily set the machine to enter the boot picker on startup so you don't have to hold...

Looking at StdCLib, I have trouble making heads or tails of how things worked in practice, the list of caveats seems large. A few snippets: It gets weirder, prior to 7.6 it seems the system itself provided no StdCLib updates, meaning you always had what was in ROM which seems like it may vary...

I've been using the Sonnet 8.5 enabler to run 8.5 on my Power PC upgraded Quadra, and it seems to run well enough. So I figured I'd give 8.6 a try, but after running the upgrade installer and rebooting the machine just dies with an "illegal instruction" on boot. Quickly, and even with no...

The SuperMac cards (particularly I've looked at Thunders) appear they may support HDTV output from references in the ROMs and various documentation. Unfortunately, I haven't seen any manuals for the Thunder series. Does anyone know if it's possible to activate HDTV modes, and what triggers the...

I'm continuing my old disc spelunking (can you tell?) and found another oddity on the 1992 Nordic support disc: http://macintoshgarden.org/apps/apple-nordic-support-cd-1992 This might be old news, but I wasn't aware there's an official (unofficial) extension to add HD20 support back to machines...

I've long wondered, why doesn't a ROM-in-RAM utility for the Quadras exist? It was common for 030 and 040 accelerators, and the 68k AV machines had it natively (enabled with a PRAM switch, which AV Turbo ROM can flip for you). (I know you're thinking -- is it because performance changes are...

Hey folks, I got a little distracted from regular ROM mods by some interesting quirks of the Radius Rocket. I ended up writing...a lot, so the full post is on my personal site, but I'll summarize things here: https://eharmon.net/retro/radius/rom_extraction/ TL;DR: The Rocket's Macintosh ROMs...

A companion to my RocketWare thread, but separating out RocketShare cause it's a whole different beast: RocketWare 2.0 or Betas? I've finally got a Rocket in my Wombat system to play with, and while probing around I've generated some questions: Does anyone have the RocketShare manuals? I can't...

The RocketWare 1.3.2 readme makes the following note: Some of this was added to the 1.5 release, however it's readme notes: Which makes me wonder if there's any 2.0 betas floating around out there with some more features.
