Rob and I have been discussing 9830s lately (and
thanks to Rob I have
one to work on here) and we realised, somewhat to our surprise, that
Good luck :-). I am currently helping a guy in ythe Netherlands with his
9830. So far we've found a defective 74H106 on the mmory addres PCB that
was causign the memroy control state machine to go crazy, and the na
defective 7400 that was causing the memory contorller to run all; the
time, I am now waiting for his next set of results...
So just how widespread or prevalent were 9830s in
schools - did
anyone else here encounter the 9830 in highschool (or gradeschool)?
Not i nthe UK. Over here schools rarely had computers bnfore the RML380Z
or the BBC micro.
However, in the mid 1970s my father met somebody at Salford University.
I ws shown soemthing that was described as a 'calculator'. Now, I was
young at the time and don't rememebr it too well, but I am pretty sure it
was an HP9830. It might ahve been a 9821 (but that's much rarer), it
might have been a Wang wit hthr tiem drive in the same sort of place,
but on balance I think it wasa 9830. And I have rough evidence that they
were not unocmmon in other UK _universities_ at the time.
