In the very early 80's my wife's PhD theses was written in Scripsit on a TRS80 model 1 (with expansion box).
The expensive bits were the floppy disks! 84kB (I seem to remember) a time - which subsequently got updated to double density through a US-sourced "doubler" board that had a different controller on it....
Relocating the RAM (on bigger, 64kb chips that weren't available when the machine was on the market) to the keyboard greatly improved reliability as like others of the era, your whole document was in memory!
Scripsit got hacked to make it do all sorts of things that more modern printers could support - like addressing individual pins which we used to print Greek letters!
After the thesis, it got used to produce - both analysing the data and writing up - what has become quite a seminal paper in its field that's still findable on the Web as a scanned image of the (new printer ribbon!) dot matrix printout produced by the TRS. Someone even wanted a copy of the (compiled Basic) program I used for the analysis which made me rather chuffed..
One of the things that set the TRS80 apart was the fact it had a decent Cherry keyboard - that taught me to touch-type although the keyboard unit needed a wrist rest as it was thick...
Happy memories - I think its still in the loft!
