TRS-80 "Eight Meg Disk System" questions... - test-drb@ccmp.vtda.org

  1. The proper host interface board (this is the card
that goes in the 
 Model II/16/etc. cardcage) The 8meg controller had large red heat sinks under the
TTL chips.

 possible to 
 substitute a hard drive controller for a 5mb TRS-80 hard 
 drive for #2 --  I don't think the newer card will work in the older units.
