[M100] M100 memory

[Ed Graffius]

Ok, Its working well and I have been poking around (but not peeking if bad 
BASIC puns are allowed).  I need another 8K
each module must be 8 k right?  is there a source for them today?  likely not 
new...but used?  NOS?  salvage?
I need to find the cassette adaptor pinout and a plug - have a solution to 
try....save files in thru the media player on THIS machine as .wav using the 
mic in jack and loading using the speaker out....a sort of 'virtual cassette'
