StuffIt Expander 3.5 seems more appropriate on a SE/30, and it works on up to System 7.6 Macintoshrepository Note the StuffIt file format changed with version 4

Since your HD is dead, you should replace it with a ZuluSCSI or a BlueSCSI Device. Install a bootable drive image on your SD card, plug it into your device and your all set.

That’s going to be a problem. The only fix I know of is to remove the bad SIMM slot and replace it with one that has a metal retention tab. This is a difficult repair and requires desoldering equipment.

I noticed those SIMM slots have plastic retention tabs. I’ve seen these become unreliable on other computers after many years. The slots no longer provide enough force to keep the contacts in the slot in contact with the SIMMs. The thickness of the PCB used to make the SIMM seems to be a factor...

Could you state what version of the ‘recent’ MacOS you were using?

I can burn the install CD set (3) for OSX 10.3 if you need it, and send it with the screen. This will get you up and running. The optimum OS for this machine is the last version of OSX 10.4.x, but that’s a DVD and I have no way to burn a DVD.

He borrowed the 74LS174 from another board, because this chip had failed on the board he was working on. The pizza box mod sounds interesting.

Yesterday on Adrian’s Digital Basement YouTube channel, he demonstrated how to upgrade the memory on a Mac Classic without using the RAM expansion board and memory modules. Adrian said this upgrade has never been done before, and involved removing two chips from the logic board, installing some...

I have this computer with a bad logic board, but good screen. Let me investigate how to remove the screen. If I remove it, you can have it for shipping.

I think the primary reason there were so few Mac demos was lower priced color Macs were not introduced until 1992 (LC II at $1240 list) and even these lower cost color Macs were 2.5 to 3.5 times the cost of an Atari ST, PC XT clone and Amiga. The Atari ST and IBM XT clones were available by mid...

Are you sure it’s not a feature? FYI ZuluSCSI features an option to emulate SCSI hard drives sounds.

Looks like the case is OK. You might want to install a Raspberry Pi 4, and download and install PiMega 4. This is an excellent Amiga emulator that runs faster than any real Amiga, and it also includes a fully working Shapeshifter (Mac emulator). You’ll need to buy a licensed Amiga 1200 Kickstart...

That is a lot of parts being discontinued at once. I see they are accepting orders thru June 29, 2024 with deliveries thru December 28, 2024. My guess is there are a lot of AI chips that AMD has announced and they want to start building, but there is little available space at their Fabs so they...
