[net.micro.atari] ATARI 400 memory expansion

jej@bunker.UUCP (John E. Jagodnik) (07/12/84)

My brother-in-law bought an ATARI 400 (against my advice) and now
has discovered that it has too little memory!  While ATARI claims
it is not expandable, several independent vendors offer 40K RAM
expanders.

Does anyone have experience with these?  If so, are they any good,
and can the ATARI BASIC interpretter access them (since that is all
he can program in!)?
