Results in selecting 2758 (note menu selection has side effect of
resetting all toggles) and calculating the checksum.
Advanced Example
C>pgmx filename [mz,ts,u,tn,@20000-2FFFF
Results in selecting 27256, split mode, doing a blank check, program-
ming the eprom with hex data residing between the 20 bit addresses
of 20000 and 2FFFF inclusive, and calculating it’s checksum.
This particular file is big. Don’t be afraid that PGMX has hung up. It has
to check the load addresses of every record in the file, and it would
take a minute before it reached records at load address 20000, unless
the file was created with an “exotic” compiler in such a manner that
segment records with apparently random addresses are placed at
apparently random locations every few records in the file. No joke
intended.
The boundaries specified cover a 64k range, but the eprom is only 32k.
The reason for this is that in the split mode, the 2 eproms are considered
as one eprom of twice the size. However, if an error message is issued
during programming in the split mode, the address given by the error
message is the physical address in the single eprom.
