Hi Joe
'Not many 1702's made. They are truely rare. 1702A's were
by the milions. 1702B's were not made by Intel that had
already stopped producing them by then. I think AMD was
one of the manufactures of 1702B's. I have one someplace.
I don't have a 1702 but I do have a 1602 that uses the
same algorythm as the 1702 does. I can program 1702's
with my sim4-01 setup but I'd need to change the code
a little to match. There is a hardware switch as well.

Hi
I'm sure you mean 1702A or 1702B. The 1702 used
a different programming algorithm!
I wasn't aware of that. I just checked the programmer and the plugin in
it says 1702A. IIRC the EPROMs that I was using were 1702As. I don't recall
ever seeing any 1702Bs. I've probably seen 1702s but I can't say for certain.

Hi Serge,
I was probably the one that asked the question! As you already know from
our direct E-mails I have a Prolog programmer and the plug-in for
programming the 1702s. I've been able to use it to copy 1702 EPROMs but I
haven't been able to read or alter the EPROM contents once they're in the
programmer's buffer therefore I haven't been able to alter the programming
in the 1702s. I don't know if I was doing something wrong or if the
programmer has a problem. Like you I was looking for a manual for the Model
900. I have the manual for the 980 but it doesn't help with this problem.

Hi,
Sorry to bother you, but I just saw a question you asked on classiccmp.org
about programming a 1702 on a Prolog M900 machine.
Did you ever get an answer or figured out how to make it work ?
Cheers,
Serge Roube
