|the enterprise was the last of the sinclair programmables.
the build quality was poor, like all the other machines. it had click
buttons like the cambridge style and the on off switch was dodgy. it did,
however, have 80 steps of program memory in which quite a lot could be
achieved. it came with a rather comprehensive library of programs. it took
a pp3, 9v battery like all the others and the program was lost when
it came out a bit too late and most of the programs were derivatives of
the older cambridge programmable which was smaller and had less memory.
function accuracy had been improved for this model. the other sinclair
machines were notoriously inaccurate for even simple operations.
