Today we're gonna take a look at a 1991 Macintosh Classic and see what goodies lie on its dying SCSI Hard Drive! [Social Media] ● Twitter - / frokfrdk ● Instagram - / frokfrdk ● Discord Server - / discord
The ports from left to right are ADB, Floppy, SCSI and two serial (these can be used for printers/modems/networking Macs together. I think there is a missing cover on the rear - those look like the holes for screen adjustment (usually a plastic tool is used for adjustments). This Mac can support up to 4Mb RAM which will allow it to run anything up to System 7.5.5.
The interrupt switch triggers a high priority CPU interrupt which halts code execution. It's used for debugging programs. I'm pretty sure it also launches the debugger if it's installed.
I have on, but the FUCKING FLOPPY DRIVE is killing me! I recapped the motherboard ,maxed out the RAM, and replaced the fan. I have a Wombat USB-ADB adapter, two BlueSCSI adapter, and a Floppy EMU. I also have a Mac SE FDHD. The floppy drives it came with are busted. One worked, and I accidentally broke a head cable on the other while I was disassembling the unit. I forgot to disconnect the cables.
This is the export version of the Mac Classic, which was sold in various places in Europe as well as in AU, and so needed to mention compliance with German, Swedish and Finnish regulations. All CRTs produce X-rays because of how they work (smashing electrons into something with enough energy will create X-rays as braking radiation). This is also why CRTs are so heavy; the glass is leaded to keep the X-rays in.
The ports are labelled; why did you point at the ports labelled with the floppy and SCSI icons and claim that one was a printer port, especially when one of the serial ports was labelled with a printer?
