Yes, they are.  If you look in the archives, for programming 101+808, they
show/explain the basics of trying to read a prom.  Also, search Delcoedit.
If you want to spend $15 at syty, there is Promgramming 98 which is a
fully disassembled 128K prom.  If you hunt in the archives, with in the
last several weeks I posted how to run the syty program in a 730.  That 
is a 2 bar MAP program, but will work in a distributor'd MAP gm application
using a 1227730 ecm.  Rather than just saying 90 MAP TPI, it would be
alot more meaningful to say what ecm, at least to me.
