HP (etc) Logic Analyzer connection to 6502 making up a "permanent" adapter

[davidshoe]

I have an Agilent 1692A and want to make up a bit more robust / permanent connection to go from the pod 1 / 2 cables to a DIP clip for the 6502.  I have it all connected now with the fly wire pods and while I could leave the two fly wire pods always connected they take up a lot of space over the board and are prone to getting caught.

Was wondering if anyone had suggestions on how best to go from the 36 pin .100 connector at the end of the ribbon cable to a dip clip for connection.

One way is to just (hot) glue an IDC connector to your PCB, and solder 0.2mm "enameled" wires between the IDC connector and your measurement points.

Someone on the forum here built this cool 6502 DIP probe adapter. You would need an E5378A Samtec probe adapter to use it.

Ohh, I like that.  I do have a couple of those adapters.

Thanks.

I recently designed a compact 6502 / 65C02 adapter board to connect 6502 systems to HP analyzers that use 40-pin pods. The board has all the terminator R-R//C networks required and uses only two pods (I've seen one out there that requires 3). With 2 pods you only have 17x2 = 34 channels which is not enough to cover every line on the 65C02 so to get this I provided jumpers that let you choose which CPU pins you want to monitor outside the absolute essentials (ADDR, DATA) which are hard wired. To use the adapter board, you pull the 6502 from the main board you want to probe and plug the 6502 into the adapter board which then plugs back into the main board. Obviously this assume there'e a socket on the main board, if not, go get a 40 pin DIP clamp and patiently attach probe leads. I'm finalizing the design and doing some testing to ensure compatibility with the inverse assembler after which I might make a short run of these adapters. If anyone is interested in one, please reach out.
