Did you install the AirTalk extension? At least, I’m assuming that installing an extension is a prerequisite for AirTalk showing up in the Chooser (just like there are extensions for different Chooser printer drivers and AppleTalk).
A number of folks here have recommended a plastic solvent called Weld On 2354. If you use the search function you’ll find other threads discussing it. That might be your best bet, but I don’t have any personal experience with it.
Does anyone have a copy of the LC Developer Note? I found the LC II one, but it points to the LC one for a lot of details since their architectures are so similar. So far my Google-fu hasn’t turned up anything.
It looks like it has 32, 256k x 1-Bit DRAMs, which would make it a 1 MB SIMM. What’s unclear to me is how the 32 DRAMs are muxed into a 30-pin SIMM, which only has 8 data bits. Maybe those other two chips do some sort of chip select decoding based on address? Not sure. Either way, I think you’d...
SCSI buses need to be terminated at both ends. Since the SE/30 only has one bus that’s shared between the internal connector and the external connector, you should always leave the internal drive terminated. When you connect an external drive, that drive should be terminated as well. If you have...
There’s this list at TinkerDifferent. I have an M1212 I need to recap, but haven’t tried yet, so can’t vouch for it.
That cable is probably a Mac serial (Mini-DIN 8) to PC serial (DB-25). The only 25 pin port on the back of the Plus is a SCSI port, which is not electrically compatible with a serial port. I’d unplug it right away and not try to use that cable for this purpose. Hopefully nothing was damaged.
I could be wrong, but I believe that the Z100P2 is actually a PC parallel port drive - the Mac SCSI version is the Z100S2, which has the SCSI ID and termination switches. I’d disconnect the Zip drive immediately - hopefully the SCSI chip on the Mac hasn’t gotten damaged.
