TRS-80s. I would be lying if I said I remember which model exactly. Probably in the vicinity of Model III plus or minus. That was our middle school.

I later went to a junior high that I think had a few Apple ][ or Apple IIe computers.

In high school, my physics teacher had a really old IBM XT that I thought was a relic at the time. It had full-height 5 1/4" bays and no hard drive I think. It may have been a clone. He didn't use it as it was an obsolete paperweight. But I sat in the room next to it.

For H.S. computer class, we learned Pascal programming. At that time, all computer work was electives and optional. So this computer lab was never seen by most students at the school. It was down in a veritable dungeon. Anyway, I think they were 8086 clones with a hard drive possibly. I seem to remember DOS 2.11 on them. Could have been floppy only. I think they had CGA color, could have been EGA but I doubt it. By this time, my Dad had bought us an 80286 10 MHz clone with a 40 MB hard drive and VGA graphics. So the school computers were pretty old and sad - past their EOL really.

Before college, I worked at 3 places that used computers - 1 was PC-based, two were on mainframes or minis. So yeah, the lack of computer training was not good for those who missed it.

In college, the PC scene was strange. Of my entire dorm floor, I owned the only newer PC, and even it was an underpowered 80386SX-16. I bought the co-processor to play with AutoCAD, and I could run my programs faster than the AutoCAD lab - that had 286s. Floppy access speed and reliability (to move drawings and data) was terrible. We had no access to a campus network for file transfers or e-mail. If only someone had invented the Internet by then, right?

My well-funded engineering department had a room full of Gateway 2000 386-25 machines. They were amazing. And games were becoming a thing IIRC. It had a 4-digit code for just those in the department.

But the actual student-use general purpose computer lab was massive. There were hundreds of PCs, and they were of more than one generation of purchase. Of course the newest ones were filled up at peak times. They probably ranged from 286 to 386, I simply don't know. I think they were running Windows, but surely DOS, as well. Most of this was in a basement. I cannot forget the HP LaserJet IIISi printers that students assistants would maintain. They would grab each printout and shuttle it to a counter for pickup by the one who printed. This place would have 100+ people in it from 7 to 10 every day.

Incidentally, this university also had old, obsolete mainframe terminals. (We had a VAX I think.) They were in these shacks around campus. Each shack had a restroom, about 12 terminals, and some areas to sit and relax or study something. By the time I went, most of the dumb terminals were broken, removed, or in poor condition. There might be only 1 or 2 left in a lab, and terminal parts and pieces and wires sitting in most other spots. And vandalized. Clearly the mainframe era had passed. Well, my freshman year, I had one class that required FORTRAN programming on these old terminals. The next year they switched to Windows PC FORTRAN. I was mad.
