I know, not really repair, but this newsgroup has at least as good suggestions as the others and I'll cross-post to sci.electronics.misc.
I need to either build or acquire an up/down counter with LED display that is at least 5 digits, 7 preferred. Count speed is 10 MHz max.
I found the Maxim ICM7217
which seems easy enough to use - 2 of these and a bunch of 7 segment LED displays. But I'm open to other suggestions.
Even if someone had a complete unit scrapped out they'd be willing to sell cheap! :)
Thanks.
