 Ok, I've got another RAINBOW 100 question.  I'm in a situation
 where I REALLY need to be able to use two comm ports.  I have
 the "regular" comm port functioning ok (although that was 
 a feat in itself), but need a second.  Does anyone know if you
 can READ the PRINTER port?  What documentation I have indicates
 it is output only, but has anyone tried using it for input?

 Secondly, I know there are some CPM files on Compuserve.  Does
 anyone know if there are any sites accessible thru internet
 (other than perhaps SIMTEL20) that has additional files?

 Thirdly, is anyone familiar enough with the memory cards in
 the RAINBOW to know - were all the memory cards basically the
 same, just with different chips, or were they fundamentally
 different?  What I have in mind is that since we have 16 of 
 the things, maybe I could pull a card out of one machine an
 put it in another to increase the memory size.  Or alternately,
 maybe I could replace the chips on the board with larger
 capacity memory chips?

 Thanks for any advice.  I've ALMOST got the system working 
 (will post my experiences when finished....).
