Easy: 820/6/17 MFM (seen them very often when it was around in past
but now most of them have died off fast.)

That's CDC.

Yup. Don't be too bothered if it's bad. S0S failure is the loose
rack gear held down by 2 female hex screws to slider table that heads
rack mounts to without any locking provisions. Too common! I seen
these 5 out of 10 ratio. I think that's in 34xx series. I think 30xx
series is voice rotary type, 5.25" HH.

Correct. All of zeniths in 1xx and 2xx series are passive slot type
with cards in it. Well made and very compatiable.
Had fixed few and very trouble-free for years, that helped my friend
to go through unvirsity with a turbo 8088 XT desktop w/ 20MB in it
after I replaced a socket on mem card! I don't know if my friend
still have it. I love those CFC containing stuff to wash out cards.
They came out like new. CFC now banned which I agree.

The Z148 is low cost version of 2 nonstandard boards slimline machine
w/ 5.25" HH bays side to side. 2 slots via optional daughterboard
plugged into i/o board. Very common item, I saw about 5 in last 2
months. All parts (chips) can be used to repair the 1xx
series passive bus desktops.
