What do I need to connect a HP Thinkjet printer to a Commodore 64C. The Commodore 64C has a serial port for disk drive and printer chained, if I remember correctly but the connector is not standard RS232. My kids use it and I haven't looked at it for a long time. Do I need a converter? Is it expensive? bentley!judah

Wouldn't the lasar use the standard Centronics connection?
If so, any of the readily available Xetec interfaces should
work out fine. It goes from serial to centronics. Someone
using the Okidata Lasar did have to make up a new printer
file, but it works fine, with one bug still being worked out.
Apparently setting up for use with proportional fonts is
difficult, but possible. BTW, cost of the interface is about
$30.

If the Thinkjet is an RS232 (serial), not HPIB/IEEE488, you should be able to hook it to the C64 "RS232" port, through one of the standard converters that makes the C64 port into real RS232 levels. See other discussions on the net for pointers to such converters; I made my own, and have indeed used it with a Thinkjet. Jameco in Belmont (I think), CA sells one, and I'm sure others do, too; about $35, I think.

Thinkjet is an ink jet printer, and comes in four flavors: HPIB (aka IEEE488), RS232, HPIL (proprietary HP interface) and Centronics parallel. So in my note above, I, too, misspoke! If it's a Centronics interface, you'll need one of the standard Centronics interfaces commonly available for the C64. LaserJets come with a dual (RS232-Centronics) interface (and cost many times what a c64 does!) Tom Bruhns uucp: !hplabs!hplsla!tomb

CARDCO makes (made?) a RS232 interface that connected to the SERIAL port, so it still looked like a "real" printer. Last one I saw was at Toys-<backwards>R-Us. I have no idea wath the price is, or the Model number. -- ------------------------------------------------------------------- "Familiarity breeds attempt" Dave Lowrey Amdahl Corp.

Try and find a copy of this month's Transactor. There is an article
on building your own RS232 interface. I have a friend who built one
(for about $15 worth of parts) and it works fine. Don't attempt it
if you cannot read a schematic and use a soldering iron; it isn't
hard, but it is time consuming (3 - 4 hours).
