Hi Joe - Thanks for the good info.
I would like a back rom. Thanks, John K1AE

My 5370B PROM turns out to be fine (there was some operator error)
I picked up a DATA I/O 201 programmer and some NOS windowed
MOT MCM68764C to have some backups (this was probably overkill, since
I have never actually seen a failed hp counter from ROM failure)
A newly burned MCM68764C appears to work perfectly.
The programmer reports SUMCHECK 7387 for U3, 5370B Ser. No. 2438A
01154
The programmer can report in the following formats:
INTEL INTELLEC 8, INTEL MCS-86 HEX,
MOTOROLA EXCERCIS, MOTOROLA EXORMAX, and
TEKTRONIX HEX
I can read these formats to a text file using a Windows terminal
emulator to save them to a file,
however, I do not know how to make the “ROM Image”. I was hoping
to be able to say something
about the ROM version, but I do not know how to compare the files I
get to
the available 5370B ROM image? The DATA I/O 201 does not appear to
directly save the binary file.
I can supply a few replacement 5370B ROMs at cost plus shipping if
anyone needs one.
Regards,
Joe
