Interest check - Extender boards for TM500-series modules
« on: November 18, 2018, 02:03:31 am »
I've acquired quite a few Tektronix TM-500 modules, most of which don't work. Repairing them is incredibly difficult because they have to be slotted into the power supply rack in order to be powered on. I've looked for extenders and they're all either very expensive or no longer available.

What I've thought of is a design using using two separate boards, one that gets connected to the module, the other gets connected to the inside of the power supply. They'd be connected with a ribbon cable of some kind.

Would anyone be interested in this sort of thing? What would you be willing to pay for it? Would you prefer to purchase as a kit (components and boards all provided, just needs to be soldered) if it was cheaper than a fully assembled board? Note that a kit would involve soldering multiple 58-pin connectors.

You don't need to make those. You can get a pre-made extender cable for cheap. I've used then to repair many TM-500 modules. They are listed on Ebay as JAMMA extender cables, for troubleshooting video game boards, but they use the same connector. The only thing is you need to cut the trace between p1/p2 and p3/p4 on both sides, their boards require that configuration but it's a bad thing for these Tektronix chassis.  :)

I told my friends I could teach them to be funny, but they all just laughed at me.

You mean something like this?   I sell kits for $20 each plus shipping.

They use two 40-pin IDE cables to connect the boards.   Kits include two boards, cables, connectors, LED.

I'm interested in one of those extenders.  Where do I get it?

Thanks
