new hamfest additions

good size hamfest in greensboro, nc and here is what i picked up. epson hx20 complete with plastic carrying case. where can i get the tiny cassette tapes for it and it also has a expansion unit added on the left. what does that do? no ac adaptor to test yet. the guy also had a commodore sx64, but too expensive. also picked up a ps2 model 60 that worked fine once i ran reconfig on it. an interesting find is a complete ti99/4a system still sealed in its box along with the expansion unit and optional floppy drive, all for $15. the 3 boxes were never opened until i did it. it's the beige model rebadged by CDC for schools here in raleigh. i also got ~50 disk based school software titles for it as well. all of it's worthless of course, but interesting to find something well over 10 years old and never saw the light of day until now. david
