Message from: Uncle Roger &lt;sinasohn(a)crl.com&gt; drives, as well as lab stuff. I'm pretty sure I've got an IEEE-488 interface for the VIC-20 around somewhere. < Yep. Commodore used it on the full PET/CBM line for disk drives, printers, and whatever else you wanted to attach. That was one reason PETs were fairly popular in labs in those days-- easy to plug in test equipment. Gil Parrish 107765.1161(a)compuserve.com
