After all that effort in getting it to you..... Not surprised ;-)  

I never found the additional Z80 pod I used to have but there are still a
few places left to look

I have a 1611A with 6502, however, have very little use for it, as i have
many other test tools. It was donated to me, but I never turned it on lol.
