[time-nuts] 5370B PROM

[Joe Geller]

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
