The PET was one of the biggest sellers in the 1979 / 1980 period,
when computers were aimed at both the home and business market.
This was a revised model of the first machine, with new keyboard launched in 1977.and was used for
education, hobbyists, and some business users. The first machines
had either 4K of RAM, or 8K, but even this was very limiting
so several third-party memory expansion boards were available to take
the memory up to 32K. It has a built in system ROM (6K) and BASIC (8K),
and with additional memory could run 6502 assemblers and even compilers
The screen could display upper and lower case letters, and a large range
of graphics symbols, a large library of software was produced for the
The 2001 model was found to be slow in updating its display, until
someone discovered a way of speeding up the graphics routines with a
POKE to memory. This was fine, but on later machines the graphics
hardware was improved and the same POKE caused the screen to go blank
and was known as 'the killer POKE'.The keyboard of this model came in for some criticism for its chiclet
style keys, that resembled chewing gum of the same name, also the keys
had a tendency to rub off.
