David, I picked up about three dozen sealed boxes this weekend, Verbatim Datalife 5.25" DSDD. How many do you need?

Get any dumb laptop with a 386 or higher plug in an external keyboard and load dos, under dos load your favorite terminal emulator. I have a Modular Systems 486/50 with 32Mb ram brick running W98 to do that. It has NIC, Parallel, serial, PS/2 Mouse, PS2 keyboard and S7 VGA in a 3"x5"x12" package and runs off a 12V at 1A wart. It was designed as a thin (diskless) client but a 2.5" 1gb disk mounts nicely. SIIG also made bricks that would do well for that also. Bottom line is there are plenty of small systems with more than enough power to do a VTxxx. If not you can get PC104 with dualcore. But really DEC did VT52 with random logic, Vt100 was 8080, Vt220 was 8051 and VT320 used two 8051s. It doesn't need a lot of CPU to do terminal other than PC display interface and keyboard is high software overhead. So there exists enough hardware out there that is smaller than the keyboard and a 15" LCD already. >BTW, from where I'm sitting the most important thing is how such a >device handles the keyboard, I need the keypad to act right when I'm >in VMS. I have yet to find a PC terminal emulation that gets the keypad near right. Some fail badly on VT52/100 emulation as well. So when the OS want a VTxxx I have a VT100/125/320/340/1200 as needed. Another area where they fail often is the DEC request "what are you" and often most terminal emulators put squiggles on the screen rather than handle the ESC correctly. Allison >Zane >-- >| Zane H.

airport x-ray machines: can they damage 8" floppies?

by legalize＠xmission.com

I'm going to VCF/nanotech thing by plane and I thought this would be a good way to bring Al some 8" floppies (PLATO system!) to archive/image, but I wondered if the airport x-ray scanner would do anything bad to them? I'd hate to damage them on my way to having them archived... -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://www.xmission.com/~legalize/book/download/index.html> Legalize Adulthood! <http://blogs.xmission.com/legalize/>

Tandy! Pocket! Mania!

by spectre＠floodgap.com

Just in time for my VCF exhibit this weekend, I've finished putting up some pictures and commentary on the Tandy Radio Shack Pocket Computer line. The site is split up into PC-1/3/8, PC-2 and PC-4/5/6/7 pages, with catalogue number listings, specifications and links. See them in person this weekend! http://www.floodgap.com/retrobits/tpm/ -- ------------------------------------ personal: http://www.cameronkaiser.com/ -- Cameron Kaiser * Floodgap Systems * www.floodgap.com * ckaiser at floodgap.com -- Proponents of other opinions will be merrily beaten to a bloody pulp. ------

Info about a Mullard Core

How sure are you about it being Burroughs? Wouldn't they be using U.S. components rather than British? I know Cadburys bought an ICT 1300 series machine around 1963/4, and its now in a museum in NZ. It was a 48 bit machine, but I think it had a much smaller store of 1200 or 2000 words and would have cost around 100,000 GBP. I have read there was an option to replace all the 'barn door' core stores with a single store of 4,000 words of 48 bits, though I've never seen one, nor the logic diagrams. I have always wondered whether it used a full binary decode (using 16384 words to provide 4000 words of usable memory) of the 14 bits rather than a BCD decode. The 1300s use lots of Mullard components. Just a small piece of a jigsaw puzzle, maybe not even the right puzzle! Roger Holmes.
