It's sad how utterly worthless PCW had become ten years later.

Seemed like a piece of cake until it dawned upon me that the program has got
to be stored somewhere. =/

Well, the definition of a home system had probably changed a lot during those
three years. 1981 home systems were probably a lot cheaper and less involved
than a 1978 one. And with a different target group, too, I think.

Apart from the extremely short-lived Commodore 900, were there any other Z8000
based systems? It seems odd to me how a company which was a giant in the 8-bit
market didn't even make a dent in the 16/32-bit one.
