Would like to locate someone who has used the Electronic Control
Technology Inc. (ETC) s-100 motherboards with IEEE standard boards.
I have a MB-20 motherboard and 30 Amp power supply that I have been
trying to use with Godbout boards. The boards (disk1, interfacer3,
8085/8088 cpu, and ram 17) are currently running in a TEI box. I
have checked the MB-20 for shorts, grounds and continuity and every-
thing looks great. The one big difference I noticed is the type
of bus termination used. The TEI has a termination on each bus line
while the MB-20 does'nt. I find it hard to believe the MB-20 is suf-
fering from noise. A while back I used the board in an IMSAI boxs
without any termination at all. Any ideas?
