1621.0. "Will it go ....BANG!" by SUBURB::PEAKES (Who is this guy anyway?) Tue Aug 23 1988 12:52

    Just another note about the dangers of pin 14 on the parallel port.
    
    I've read many horror stories in magazines about the +5v pullup
    shorting out the psu when connected to printers not requiring this
    power.(When using a standard IBM Pc parallel cable on A500)
    
    Has anyone had any experience of this? 
    
    I'm loath to use my parallel cable from my pc on my A500 with my
    roughly Epson Compatible CENTONICS GLP printer until I am sure it's
    not going to destroy the serial interface or something equally cash
    sapping.
    
    I've noticed that there has been discussion of this in previous
    topics but noone seems to have mentioned this little problem, or
    whether indeed it is a problem or not.
    
    Sorry to prolong the agony of the printer cable saga but can we
    just get this one cleared up once and for all.
    
    :-)
    Cheers,

I used a standard IBM Pc cable on my A500. My believe the +5v pullup goes
to a logic input that wants a high level. I would have preferred to drive
the signal with a true logic high but it's worked fine for 9 months now.
My printer is a Panasonic 1092i and I use the epson driver.

    Me too.  I've been using a standard IBM Pc parallel lead with my
    A500 and the Star LC10.  There has been no trouble up to now.
