http://www.phoronix.com/scan.php?page=articleitem=plugable_multiseat_kicknum=1 This is a USB device which can plug into a normal PC running Linux (Fedora 17 is mentioned). You then connect a DisplayLink monitor, USB keyboard and mouse to the device. And you have a multi-user system on a single PC. Not a server PC with other PCs connected as clients, but just one single PC. Reminds me of what could be done with MP/M-80 (the multiuser version of CP/M-80), except back then it was a serial (RS-232?) connected keyboard/display. Or, maybe, an S/360 with a 2260(?) or 3272(?).

Doesn't really say __how__ it works internally. The author simply says that, on Fedora 17, it is truly plug and play. He plugged it into a PC running Fedora and he immediately saw a GDM login screen. He said performance was generally good, except for some HD video from YouTube. This is a Kickstart project, which means it isn't ready yet. From the Kickstart page, it implies this is an all hardware solution using ASICs. http://www.kickstarter.com/projects/1666707630/plugable-thin-client-the-50-computer -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.

Or, maybe, an S/360 with a 2260(?) or 3272(?). cp67 (ran on 360/67) delivered to the univ. jan1968 had support for 2741 (selectric typewriter with computer/rs-232 interface) and 1052 (sort of like 360 1052-7 operators console with rs-232 interface) terminals. the univ. had ascii/tty terminals ... so I added tty/ascii terminal support. the 2741/1052 support did games with switching terminal controller SAD command ... associated terminal specific line-scanner with each port/line ... so I added tty/ascii support in similar manner. I had wanted to have single dial-up number (hunt group) for all dial-up terminals ... but ibm terminal controller had taken short-cut ... while it was possible to change line-scanner, the line-speed was hard-wired for each port/line ... 27411052 operated at same line-speed, but tty/ascii was different speed. this somewhat was motivation for univ. to start clone controller project, reverse engineered 360 channel interface and build channel interface board for Interdata/3 programmed to emulate ibm terminal controller (but also supporting dynamic line-speed). Interdata then takes the implementation and markets as clone controller; Perken-Elmer then buys Interdata and continues to market under their own brand (30 yrs later ran across one in large east coast datacenter handling large percentage of point-of-sale dial-up terminals in the US). There is some write-up blaming four of us for (some part of) IBM clone controller business. past posts mentioning clone controller http://www.garlic.com/~lynn/subtopic.html#360pcm This claims a major motivation for the Future System effort was clone controller business. There is also some implication that major design criteria for SNA was tight integration between NCPVTAM ... a continuation of the FS goals: http://www.ecole.org/Crisis_and_change_1995_1.htm And then Ferguson Morris book, Computer Wars: The Post-IBM World, Time Books, 1993, mention that distraction of Future System and killing off work on 370 products ... and then after Future System imploded and delays in getting 370 efforts restarted, allowed clone processors to gain market foothold. before there was ms/dos there was seattle computer, http://en.wikipedia.org/wiki/MS-DOS before seattle computer there was cp/m, http://en.wikipedia.org/wiki/Seattle_Computer_Products before there was cp/m there was cp67/cms http://en.wikipedia.org/wiki/CP/M kildall worked on cp67/cms at npg (gone 404, but lives on at the wayback machine) http://web.archive.org/web/20071011100440/http://www.khet.net/gmc/docs/museum/en_cpmName.html npg http://en.wikipedia.org/wiki/Naval_Postgraduate_School cp67/cms http://en.wikipedia.org/wiki/CP/CMS there is also folklore that person that did mp/m-80 had done a lot of work on cp67/cms -- virtualization experience starting Jan1968, online at home since Mar1970 -- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN

And just recently I have learned about Wayland, which is to be alternative to X, because X is too complicated (which doesn't mean Wayland stays simple over long time). Actually, I would consider using some cheap netbooted laptop(s), because I don't have to care about Windows drivers :-). And to run X-server with non-demanding 2D apps, I think 64MB of ram is much more than sufficient (nowadays, it will be a bit hard to find machine with this low mem).

Re: The old is new again - Not IBM related, but I hope interesting
John, I didn't think anyone remembered MP/M-80, let alone what it did! Back in the 80's, I put together MP/M-80 machines and wrote application software for them. We benchmarked our 7-8 user systems and ran better than any DEC multi user system. We were even the first Iomega customer and designed a board to allow their 8 cartridge to work as a high capacity (10M) storage device. Ah, the old days. How fun was that? My, we've come a long, long way in 25 years.
