Re: Line Driver Question

I collect classic computers and want to archive a lot of my original

available for classic computers to transfer to modern PCs via RS-232.
Since it's impractical for me to get the classic PC next to my primary
desktop PC, I suppose I can try a line driver/receiver adapter and a
run of spare telephone wire or CAT5 (about 45ft in this case) to get
them connected between my workbench and computer desk. That way, if I
don't finish the transfers all in one night, I can just roll up the
wire between sessions. I won't upset my better half by leaving classic
PCs connected up in the den for days.

Open up those computers, and they'll likely have one or more MC1488s and
MC1489s. The only reason they wouldn't is if they are really old, say
forty or more years old, or recent enough that the function was integrated
into a larger IC, or it used one of the RS-232 line drivers and receivers
that came much later but never had the penetration of the 1488 and the 1489.

Wherever there's RS-232, there will be a line driver and receiver of some
sort.
