I've had this adapter sitting on a shelf since 2004 and just found a use for it when working on a Zaccaria pinball MPU. The problem is it doesn't work and it looks like the 2650 CPU has to drive INTACK, but it ties low in the original article on pages 9 &10 of TroubleshooterV1-1983-combined-searchable.pdf (on ftp list under Fluke/9XXX/Fluke Troubleshooter Magazine).
Anyone else use this adapter or made one that works for Zac. games?
I sent you that one. I never got it to work correctly, though. I had a thread here on it back in 2017.

INTACK only matters if you're expecting INT to happen, and without the CPU actually running, there wouldn't be any use for INT.
