I am Looking for a LM4250H 8 Pin DIP or A real good substitute. I found
a Data Sheet but having trouble locating any Parts.
I am hoping someone has one in their Parts Box
Bob,
I bought some a while back from UnicornElectronics.com.
They are really cheap parts and it fixed my home brew S-100 bus terminator
with no problems.
Apparently those op-amps get worn out over time and just die occasionally, I
guess.
At least replacing the one on mine worked.
Thanks and good luck!
Andrew
Thanks I must have missed them; I just rechecked and they are listed on page 12 of my
Catalog.
I am adding a Terminator circuit to a Board I had made up for my BYTE-8 S-100 box
Thanks

Gifford Computer Systems Multiuser Concurrent DOS User's Manual
(includes a pile of 8" diskettes)
=================================================================
6 assorted S-100 motherboards
=================================================================
A "pile" of 14 assorted S100 cards that have never been used by me and
are untested. I picked them up (used) for future use, but never got
around to firing them up. Their condition is unknown,
and I'd like to sell them as one batch. They've been sitting in my
warehouse for 15 years, and are pretty dusty.
=================================================================
Does anyone Know what happened to the S-100 Boards and Manuals.
