[net.micro.ti] cheap expansion?

wrightb@stolaf.UUCP (Bonnie Wright) (08/12/84)

        I have a TI99/4a with Extended Basic and a tape recorder, I would like
to expand it to include a 32k ram expansion and a RS-232C interface - very
cheaply. So does anyone have schematics or instructions for building either of
these?

        Thanks in advance!
