Most computers used a speaker instead of a mechanical bell, but the ASR33 teletype has one, as does the Burroughs B80. <grin> Yeah... I dunno - I need a little more information to go on. A description would be nice. A picture even better. :) -Ian

Open source, stand alone, ASCII terminal project, UPDATE

by tiggerlasv＠aim.com

I see from the SpareTimeGizmos website that they are contemplating adding an ethernet port, with telnet capabilities. . . It seems to me that if you're going to the trouble of emulating a VT220, a DEC terminal, then you should at least add support for LAT. ;-) T

No drives... Floppy controller clearly untested... No boot or other floppy disks... The only verification of "works" is that the lights changed when the seller played with the switches.

Ah, that's a good idea, though. I'll check my fiche tank. John

Looking for MS11-M tech manual

by quapla＠xs4all.nl

Hi John, I looked in our company technical archive, and for this memory card it does seem to look like there has not been a technical manual. We have them for the other MS11 ones, but not for this one.

Does anyone have a copy of the (DEC) MS11-M tech manual, EK-MS11M-TM? Manx has pointers for the user guide and print set, but not the tech manual. I need more information than is present in those two documents. I'd be happy to scan the manual, if someone has it and can't scan. Or a scan would be great. Thanks, John

While I must admit that I don't understand the point of having a separate DTE and DCE, if companies had just followed the specs, it wouldn't have been a problem anyway. All DTEs male, and all DCEs female. Female to female cable, always crossed (same with male to male, not that I'd expect many to hook a DCS to a DCS, but anyway), and male to female cables always straight. How easy it would have been. And modem signaling are just signalling between a DTE and DCE, for various situations. But they could have defined just everything as DTEs, and made modems and similar stuff really invisible, like cable extensions instead. Maybe that would have made it easier for companies to get it right.

Promotional posters from the Honeywell "animals" ad campaign

by wmaddox＠pacbell.net

An eBay seller is selling what appear to be vintage promotional posters featuring the animal sculptures made out of computer parts that Honeywell commissioned for a long-running ad campaign. There are 17 different ones, with multiple copies (but not many) of each. http://shop.ebay.com/merchant/psobosik?_nkw=computer+poster --Bill

looking for SGI Indy Presenter cable

by spectre＠floodgap.com

Looking for a video cable for an SGI Indy Presenter Panel. My investigation indicates that a 68-pin SCSI cable might actually fit this but I'm not sure if it's wired straight-thru. Anyone have one they would part with, or would be willing to check the pins for me, please let me know off list. Thank you kindly :) -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Mmmm, Windows user.
