I ran down a rabbit hole looking at dumb terminals tonight, and unlocked a memory from 1993 or so.

I guess my main PC was down, I think I had taken something apart and gone to sleep and my girlfriend at the time wanted to dial in to probably Rutgers' Quartz BBS so she plugged everything back in and powered it up. Unfortunately she plugged the 50 pin tape drive into the 50 pin scsi controller and blew out the controller.

Someone had given me a terminal for some reason, an ADM-1A. Since I couldn't live without Internet, I plugged my Intel 14.4k modem into the terminal and could dial up BBSs and the Internet. I had this octagon shaped table in my kitchen where the screws came out of the top when I leaned on it, so I just set the terminal on the table's stand for the perfect workstation. I remember being shocked that there was a termcap entry for this 'obscure' brand terminal I had never heard of.

Anyway, eventually I got a new scsi card. A friend of mine broke something on his Amiga 2000, so I passed the terminal and a Supra 14.4k modem on to him. I didn't have a spare cable, so he wound up taking off one of his guitar strings, cutting it up into small pieces, and painstakingly wiring all 25 pins together. (He got annoyed when I told him he only needed like 6.)

He eventually fixed his Amiga, and gave the terminal to another Quartz user. She used it for a while, I think. Dunno where it went after that. Kind of the terminal version of Sisterhood of the Travelling Pants.

Printed myself a 68xx #reference guide and put it in a binder. It'll be nice having a paper reference while I'm working on the Time Machine #Pinball #disassembly effort.

I've really been enjoying having a color #printer of my very own, and I'm especially happy about the fact that I haven't even put a visible dent in the ink tank fill indicators from the first fillup. The #EcoTank was pricey, but not having to be skimpy on ink usage is worth it.

I make & sell dummy battery things since needing one in the lab myself. I conceived the little assembly of 3D printing and wire that lets you do in-situ current measurement or power injection in the tiny space where coin cells live.

Hobbyists, #makers, labs, #retrogaming and #retrocomputing nerds found them and send me orders which I grudgingly fill for a tiny fraction of minimum wage. The version shown here lets you relocate the battery outside a hard-to-access cabinet for easy changes.

Goodie number 3: yet another bus mouse I didn't need but it was cheap so I got it anyway.
Sadly, it does not contain the bus mouse ISA card. But my olivetti M24 has a bus mouse port built into its keyboard (with a different pinout, so I'll need to use an adapter).
I have a hunch this will work without changes on my PC-98, I bought this mainly to test that theory for my blog post since the logitech C7 is relatively affordable as long as you don't get the translucent version.
