Weren’t they running off of a Commodore 64 or TRS80? (If you know, you know.)
Nope, they upgraded to the Tandy 1000EX with a whopping 256kb of RAM, 5 1/4 floppy and dot matrix printer (this is actually what I got for Christmas the summer of 1987). TRS80 is what I wrote my first program on in the summer of 1986.
