Subject: ? CP/M-80 on PC-clone

My CP/M-80 system is dying.  The cost to repair is about the same as the
cost to me to buy a new PC-clone.  I want to preserve my investment in
CP/M-80 software (compilers, tools, word processors, spreadsheets) which
would have a high replacement cost.  What is the best way to either add
hardware, or add software to a PC-clone that would allow me to run my
old software?

I can see three basic choices.  (1) Get a clone, or near clone, that
supports CP/M-80 directly.  The Heath Z100, and maybe the Seequa
Chameleon might be in this class.  (2) Get an add-on board for the
PC-clone.  The old Baby Blue CPU, and the QCS Big Blue card had that
intention, but I don't know if either are still available, or supported.
Maybe buying one used would be possible.  (3) Get some emulation
software.  That sounds like it might be painfully slow.

I am very short of arms and legs to spare keeping my systems up and
running.  Hybrid solutions, like an S100 system with hardware for both
MS-DOS and CP/M might be an acceptable variation on (1).  Any good used
H/Z-100's out there?
