Datanumerics DL8A is here! Have a peek @ ... - test-drb@ccmp.vtda.org

Well the bottom line is... I'm not an electronics guy.
The option I will be following is getting the 1702A EPROMS copied and

    a) backed up to several media formats
    b) duplicated to new 1702As.

...
 I supose the solution is for him to build a 1702 reader
(which is a lot
simpler than the programmer!) and to read the EPROMs himself. 
...
 The ultimate solution would be for somebody to program
a 'spare' 1702
with a known byte sequence, and use that to test the homebrew reader. A
lot of work, though. 

No, this isn't a solution.  I'm a software guy - I'll re-engineer the 8080A
code if and when necessary, but there's no way I'm going to build hardware
for this thing.  I just want to copy some EPROMS... not delve into clever
engineering to make them redundant!  By the way, I have found several 8080A
disasemblers for MSDOS.  THere are quite a few websites around carrying such
goodies.

...
  Or the one that's
X-rayed with a sufficient dose to damage the chips, or the one that's
lost, or whatever. 

Is the X-Raying a valid problem?  Will X-Rays further damage already fragile
EPROMS?  As I said, I may have found myself four 1702A EPROMS, the only
problem here is getting the code from A to B.  Maybe the ideal solution
would be for me to borrow a 1702 reader and do the job over here.  That way,
the irreplacible EPROMs don't travel at all.
