I do actually :-) But maybe because I am old enough. Actually Turo
Pascal was a great system by that time, for many years I refused to
switch to C as it generated much smaller code than MSC, Think C or
even Turbo C. I think the only real alternative was Watcom but my
memories may tricking me.

Wow, that's great news (multiplatform MPLAB and C16 as well)! Thanks for that!

It would be so great seeing MPSIM on Linux as I just love the stimuli
capabilities it gives. BTW: This device simulation goes as far as
spice simulation as well? I guess that is not a public product either?
Thanks,
