The main modification visible externally is the numeric keypad. This was added from parts of a second computer, and the story is kind of interesting: two MZ-80Ks were stolen from the company that owned them. After the insurance company had paid for them, they were recovered by the police, but the thieves had already broken one up for parts.
Since both the complete machine and the parts now belonged to the insurance company, which had no use for them, they were sold for far below the normal price (remember this was in the early ’80s, when even a simple computer like this cost a small fortune). That allowed my father to buy the complete machine and spares from the other, including a keyboard. From that, he made a numeric keypad, sawed an opening for it in the case, and added it to the machine. The inserts in the keys are simply pieces of coloured paper with dry transfer numbers and symbols on them.
The Sparkfun keypad pcb's have a weird mounting hole pattern, probably based around the 2x2 silicone button pad. Due to the design & dimensions of the Machinecollective.org enclosure (based on the design of our protomodules) you'll have to reduce the size of the keypad pcb. Some of the options are cutting, filing, grinding or biting, make sure you don't hurt yourself.. ;-)
