Old BYTE magazine GPIB to centronics printer interface

[Bob S.]

Hello. Does anyone know were I can find the old BYTE magazine GPIB to
centronics printer interface article. (circa 1979 +/- 4 years)

Regards, Bob S.

The GPIB state machine is exceedingly complex. If you need all of it,
go buy the chip. The good news is that many applications need almost
NONE of it implemented. If all you want is to be the controller in
charge, you just need to address the device and handshake the data.

If that will do, email me and I'll send you some basic code written for
a PIC processor that implements RS-232 to GPIB. Should be easily
adaptable to centronics.

If you want to use the printer port on a PC I can email you this:

This archive contains files that describe how to convert an inexpensive
parallel printer adapter on a PC to interface with GPIB (or
HPIB/IEEE-488)equipment.

Don't know where I got it, so can't give you a link.

If you don't need to use the national instruments code, you can buy
older non-compatible gpib cards for cheap.

And if you want to use an old printer from the GPIB it is simple. This
wont work with newer
printers with data going both ways.

You take the handshake lines from the printer and connect them to the
GPIB handshake lines.
You use inverters on the eight data lines from the GPIB and send the
data to the printer.

I did this years ago and it worked fine. You can't have any other device
on the GPIB buss
as this interface takes any data and prints it. Sorry but I don't have
the pin connection
data available

Good luck
