I can't say I have done it, but an alternative to
using (and finding)
TTL->ECL chips would be to use standard voltage comparators.
I left this as an
option in case I couldn't get the TTL->ECL converters.
This would have the added advantage of placing a far
smaller load on
the signal lines being tested.
I placed some 74HCT bus driver chips in front of
the standard TTL inputs
of the TTL->ECL converters to get higher input impedance. My main
interrest for geting this LA to work was to debug self made
microcontroler toys. So I could live with the fact that the pods are
slower then the LA.
