Subject: TPM and RST's

  Wqlt,
  I qm running TPM, a CP/M variant produced by Computer Design Labs of
Trenton NJ.  It is CP/M 1.4 compatible, but not 2.x compatible.  TPM
uses RST 0 area for boot, like CPM.  It also uses RST 6 and 7 for system
software.  I believe that CP/M also uses at least one of these RST's,
for DDT's run-time breakpoint.  The TPM manual states explicitely that 
RST's 1 thru 5 are available to the user.
  If you ever complete a list of what publicly available software uses
which RST's, please publish it...
  Good luck.
     -Steve
