I've been reading on "another site" about someone who's trying to update an old PicStart+ that currently has the original 17C44 installed.
Been there, done that, for half a labful of PicStarts: fortunately at that time the Microchip updation PCB was available so I bought about 10 of those and did the needful doings.
I'm not sure I'd care to recreate that little board myself but I'm sure it's doable.
Having looked at the picture on the Farnell site it looks eminently doable, dunno about any bootloader the new chip might need though.
I was mildly interested to see that the PicStart had a number of Siliconix analogue switches inside it.
I think they were DG308 quad single switches.
Which, in turn, brought back memories of writing test programs for ATE to test said analogue switches.
