Hi Jules and all
I suppose my Acorn System One is probably my smallest
system - two Eurocards,
Sharp PC 1500.
Used it while studying. Had all my formulas in there, from integration
to hex conversion.
"Tricked it out" by adding a 32K ram on a PCB in the place of the normal
16K memory module.
I have the manuals to program the thing in assembler so it definitely
counts as a computer not a programmable calculator (I do regard the
smaller Sharp jobbies as glorified calculators even if they have
BASIC and a full mini-keyboard.
