IEEE-488 interface and Commodore Pet

Same here, when I bought 2 model 70 IBM PS/2's with microchannel IEEE-488 cards, they cost me $50 each but I knew the seller knew nothing of the internal cards. I turned one unit around (thinking I'd get my $100 back) and it closed on auction for over $350 and the buyer was happier than a pig in poop to get it that cheap (I threw in a 2 mter cable as well). This was just over year ago. I had mine running with my HP 54210D digitizing o'scope for awhile but I think soon that machine is going to be on the auction block as well due to lack of time and interest. -> -----Original Message----- -> From: owner-classiccmp(a)classiccmp.org -> [mailto:owner-classiccmp@classiccmp.org]On Behalf Of ajp166 -> Sent: Monday, September 10, 2001 8:47 PM -> To: classiccmp(a)classiccmp.org -> Subject: Re: IEEE-488 interface and Commodore Pet -> -> -> Sorry but your wrong. -> -> Here in the USA IEEE-488/GPIB cards are considered industrial -> interfaces and command premium prices.
