TRS-80 Fragmentation

I see that the actual fragmentation is about how each and everyone got in touch with computers, personal or mainframe or whatever! Me, I was in junior high and usually understood everything in the math class by the first 15 minutes, after which I would become restless (bored) and the teacher would send me several buildings away to inquire about the room temperature of the computer room, which hosted an HP3000 system with several terminals (that included primitive graphics capabilities via serial connection!). It was 1978, and I learned BASIC right there. Afterwards, it was Apple II and their Franklin clones as a freshman, running UCSD Pascal... in 1982. Later it was the Z80 card in the same computers, running CPM, but just for the sake of using the Z80 assembler tools. And we were using also the said Apple II to impersonate card readers that would send jobs to the IBM 4381, as a sophomore... My dad bought me an HP71B calculator in 1984, and that really was when my numerical math skills progressed. I still do that for a living. And the height of my BS years... getting to run MATLAB in an IBM-AT with a math co-processor. Later, as a teacher, getting my first BITNET email account in 1987, learning XENIX, wiring phonenet for the Mac network at the university, then as a grad student (1989) using VAX machines at UW-Madison, but also Apollo machines, Sun 4/50 machines, and HP-300 machines... and in1990, I telnet-ed to UCSD to run jobs in a Cray at UCSD... whoa, such memories...
