Z80 / Z84C Swap (Doh!)

[drlegendre .]

Any sense of what PC models / controllers are capable of this task? Despite
my recent comments to the contrary, I just recalled that I do, in fact,
have a few old and (iirc) working PCs around here.

Here's what I think I have available. Please - anyone who might know - tell
me if one will fit the bill? All have at least 1 - 5.25" drive.

1) Compaq Portable III (286 @ 12 MHz?)
2) Tandy 1000 EX (XT clone, I think)
3) IBM 5155 luggable (PC or XT?)
4) Another portable XT clone, with an IR remote keyboard and a tip-out LCD
screen. Can't recall the brand, same size as a Compaq Portable II/III

Heck, there might be more. In fact there's also a 5120 and a 5145 but those
are both big lugs and would need a proper setup and sufficient real-estate
on already corwded work tables. How did I forget I had all this stuff?!
