Commodore PET 4016

[snuci]

Here's another one of my favourite computers because it was similar the first computer (and keyboard) I laid hands on, the Commodore PET 4032. The Commodore PET was released in 1980 and is known as one of the "Holy Trinity" of computers (the other two were the Apple II and TRS-80 Model 1). This model "4016" meant that it had 40 columns of text and 16k of memory. The first computer I used in school was a PET 4032 with 32k of memory and that was pretty sweet back then. I have one of those in my collection too.

This keyboard in each is the same and has Mitsumi key switches with a hand wired caps lock.

Here are some pics:

Ah, so all the keys use adapters. I didn't realise.

The adapter look like they could fit on Topre switches, any chance you could try that, snuci?
