I have a system (secondhand) That started life as a sort of data entry unit to let folks using timesharing systems save money by doing their data entry offline and then "dumping" it to the service.
Basically a glorified *line* editor. Wrote the lines to disk, one line per (128 byte) sector. 639 lines per disk.
Has two serial ports. One for a terminal, one for a modem.
It dates back 1977 when the first single chip floppy controllers came out.
It has an 8080 CPU, 8k of ROM and 8k of RAM. A friend used one as a BBS of sorts for years. With *one* k of RAM. :-)
