Of these computers, the CPT is the least known (to
me). I can find only one
mention of it on the Web and that guy didn't even have a boot disk for it.
At least I have some 8" disks (don't know if it works yet, still got to do
the preliminary check-out before applying power). One of the floppies says
"Tandon CPT" on it (hand-written) and a sticker somewhere suggests it was
built in Ireland. I'd appreciate some more info on it.
Hardly anything on the net about this chunky IBM Display Writer either, its
not even on the Comprehensive Computer Catalog as far as I can see ...
I'm not an expert on CPT, but I did have one of their dedicated word
processors for a while. (It may have used a Z-80, I forget. It had 3.5"
drives.) Do you know if your model was designed as a general-purpose
computer or as a turnkey word processor?
As for the DisplayWriter, the situation is pretty similar. I think you need
IBM's software to get it to work. I don't know how much reverse engineering
has been done (thus, how easy it is to run other programs).
