By and large including the 8008 and VAX I've programmed and designed with all. The key thing is I have working examples of all but the 8008. Drat, I forgot the NEC unique 4 bitters the uCOM4 and ucom75 series designed them into and programmed them as well. <What's a 3001, BTW? 3001 is an intel bit slice (2 bits per). Allison

C64 3 1/2" drive

by cgregory＠lrbcg.com

The highly sought after Commodore 1581 (3 1/2") drive is worth anywhere from $50. - $80. depending upon condition (power supply included). Post a message as to it's availability in comp.sys.cbm, and you'll have all kinds of offers.

The Wang patent relates to videotex terminals, exactly the stuff that British Telecom developed in the 1970s and pushed hard (as PRESTEL) in the early 80s. Prestel was organised a little like an ISP, with various "IP"s (information providers) renting space in which they creating "frames" of text and (chunky) graphics which were accessible by modem. IPs could sublet space, too, so individuals could rent just a single frame if they wanted. In 1982 PRESTEL launched a service called Micronet800, which used thousands of pages on PRESTEL servers to store microcomputer related news, software, etc, and started selling software to enable home micros to dial up and display/load/save these pages. Actually, stuff for micros had been around on PRESTEL before that, but spring 1982 was when it took off. I got my software and modem that summer. Most of the modems were simple devices built in to an acoustic coupler, fondly known as agnostic complicators. PRESTEL itself didn't make use of file extensions, but obviously some of the micro systesm that accessed it did. CP/M has always based certain actions on file types and extensions, for example. It did use menus of links, and the links between frames, could be quite arbitrary (and tangled!) just like the web. There was even a command to go back one or more frames, and there were "response" frames and a mail system and ... -- Pete Peter Turnbull Dept. of Computer Science University of York

As far as commonality of old machines goes, most airports have old machines. Public libraries do as well. The boston public library just replaced some Vaxen with Alpha machines. I couldn't get them to tell me what they did with the old stuff. In general, I would say that the amount of old machines is greater than a given reasonable estimate (ie there's always one more).
