I built some SCSI2SD V3 boards way back in 2014. I've just been using old firmware from 2014 without any issues, but I noticed that at some point SCSI2SD added the capability to emulate 4 devices at a time, including CD drives. Very cool! I upgraded to the latest firmware (4.8.04 as of today)...

Hey everyone, I've been experimenting with designing an LC PDS card that has a ROM SIMM socket on it in order to use the right half of the UI in Apple's Flasher app in my LC 475. Just for the fun of it! This has been an entertaining foray into programmable logic and is exactly what I needed for...

I recently tried to use mine after several years of it sitting around, and realized it didn't work anymore. No lights would come on when it was plugged in. It acted like it was completely dead. Thought I'd share my fix in case it helps someone else. I opened it up -- very brittle plastics, by...

I've been tinkering a lot with ROM SIMMs and Quadras lately. As a quick summary, most Quadras (maybe all of them?) seem to have been designed to work with a ROM SIMM. They generally have soldered ROMs and in most cases, especially on newer Quadras, the socket isn't populated. @Performa450...

Title says it all... Longtime members may remember when I did the same thing with the G3 Blue and White over 10 years ago (wow, has it really been that long?). A reader of my blog contacted me and asked if I could figure out how to do the same thing with a G3 iMac (Slot Loading), a.k.a...

A kind person gave me a Duo 210 along with a non-working (we think) Newer Technology Ethernet MicroDock a while ago. The Duo works great. I'd like to figure out if the MicroDock can be repaired. The ADB port on it works fine, but I can't seem to get the ethernet to work. I installed the driver...

I may be crazy, but I really wanted a Macintosh TV so I bought one on eBay. Paid more than I probably should have, but nowhere near the $600 range of the ones currently for sale. I guess it's kind of my new project machine. It has the black keyboard, black mouse, original credit card remote...

OK, so now I'm thinking of my next big startup sound hack and I want it to be a New World Mac. I have several New World G3/G4 Macs, but the Yosemite G3 seems like a nice candidate due to its logic board being so easy to access. It's the first brand-new Mac I ever bought. I still have the...

I've been playing with various ROM hacking stuff on the II series Macs, and I found this on eBay and couldn't resist snatching it up. It's a really weird shape! Googling for the part number 820-0482-A seems to find a few results implying it's a 64-pin ROM SIMM belonging to a Quadra 840av...

[mod mode] Introduction: by jt/Trash/Trash80to . . . whatever! dougg3 has made the most incredible introductory post to date, period! It's quite the saga of creative hackery and collaborative effort by the 68kMLA Technical Unit's Boffins and a lot of cheerleading by the rest of us in the...
