There is 74bct all over this ISA card I'm trapping pulses on.
The particular chip is on a ribbon driving three other cards as well. It
is about 25cm long. That ISA bus has an isa mounted Industrial PC and 6
Cards (Ind pc, nic, InterV3, Controller, & 3 x driver). Two ribbons are
fed to each driver card (The controller instructing the drivers, or
reading back) Other ribbons feed off thither and yon. This Controller
card is the centre of the universe here, and everything talks to it.
It's a pain in the face but the system is actually worth having - it
does function test, ASA, netgen, and is programmable.
I'd give you the url except diagnosys seem to have taken down it's
successor (Pinpoint 2) from their website to hawk their new FaultFinder
range. They seem to have Rolls Royce and Lada versions of that, but I'm
not bothered learning the difference.
Any clearer?
