Actually, the 167xx doesn't always need a special adapter. There's a good thread on HP/Agilent disassemblers here:
In post #3 in that thread there's an example of using a 16702B logic analyzer to probe a 6802 processor using flying lead probes directly to the processor pins (no adapter). The thing being probed was a Tek 2465.
On the 2445A/2465A and 2465B/2465B, Tek uses bank-switched memory, making it even more fun to untangle the code. The 2465 does not have bank switching. (Maybe IDA handles bank switching?) If someone wants to head down the disassembly path, here's some info on how the banks are handled, specifically for a 2465A, but I think the B series is the same:
I've done some disassembly of the code along with real-time tracing to figure out how some things work. It's time consuming and some of the code seems a bit hack-y as it was ported from one platform to the next.
