Yes, modern PCs only have USB now.
For the home experimenter it is like most things these days,
"Improvements for the worst."
I have read somewhere on the net that in trying to convert USB to parallel
the BASIC emulator doesn't work.
So for me, it was best to buy an old, cheap laptop with parallel built in,
providing it's bi lateral of course.
I suppose I could have gone serial but I like to see
all those 8 DATA bits dancing merrily away.
So easy for me when testing, to see which one might be missing.
Thanks for the link, anyway, Steve.
