Joe: I am with the Alaska Chapter of the 99s and we have two of the ATC-510 simulators (desktop model). We do not have any manuals and one of them is giving us trouble. I am looking for two bits of information. 1) How can I get copies of the training and service manuals and 2) where can I have them repaired? Any help you can give me would be greatly appreciated. Thanks, Brenda

The Crossbar System That Controlled MIT Trains

Message: 26 Date: Fri, 26 Sep 2008 11:47:21 +0000 From: shumaker at att.net Subject: Re: The Crossbar System That Controlled MIT Trains To: "General Discussion: On-Topic Posts Only" <cctech at classiccmp.org> Message-ID: <092620081147.20383.48DCCBC900066D2000004F9F22243429029B0A02D29B9B0EBF9D0A050E039A089C at att.net> Content-Type: text/plain; charset="us-ascii" Is it modular enough to be shippable? Have any of the more significant model railroad clubs - especially those with a historical focus been contacted? (The one in Sacramento CA comes to mind: www.smrhs.com) s shumaker I don't remember it being modular enough for shipping by UPS. Just to give you a sense of scale... The train control system measures approximately 8'w x 6'h x 1'd. and weighs at least one or two hundred pounds. My estimates are all from memory, but I have absolutely no doubt that it would have to be shipped by truck unless it was disassembled (that would mean, sadly, cutting wires). It would fit in a big cargo van or a small U-Haul. Someone with lots of space in their basement (not already taken up by trains) and a passion both for telephone technology and trains is the best candidate. --Tim

OT? HPCC mini-conference photos

by ard＠p850ug1.demon.co.uk

The reason this is OT-ish is that HPCC is not a classic computer organisation. But at the mini-conference each year it's become something of a tradition for yours truely to dismantle some strange piece of HP computer hardware, almost always over 10 years old Anyway, there are some pictures of this year's event on http://www.voidware.com/ In case any of you care what I look like, I'm the 'high mass hobbyist' in some of the pictures. In particular in the first picture (also on the homepage IIRC) I'm the person holding up a length of paper tape. Other photos are probably of more interest. This year I dismantled an HP2748A paper tape reader. There are some pictures of the chassis and at least 2 of the PCBs. Also a picture of some of my classic HPs, including a 9830 which I used to demonstrate the reader. The laptop thing is an HP PortablePlus. You see I needed to show the program listings and program output to the audience and the HP9830 display is not ideal for this. So I stuck the 11205 serial interface module in and linked that to the PortablePlus running a terminal emulator. Now I have the somewhat rare compositie video output module for the PortablePlus, the output of that I pluggged into a borrowed, modern, video projector. -tony

stuff for free/donation/trade -> cheap

by rescue＠hawkmountain.net

I'm having some roofing work done... and a dumpster is coming in.... I'm going to use the opportunity to unload (with great reluctance). I have SS10, SS20 stuff, Mac stuff, PC stuff (some systems, some 'bases' (i.e. SS10 nds cpu, graphics, ram), lots of parts). Way too much to list. Most stuff will be free (donations or trades appreciated but not necessary). If there is anything Sun (ss1 through SS20 era), Mac (68K era with some pre G3 PPC stuff too), SGI (Indy, I2 stuff), PC (286->P3 era including CPUs, mobos, cases, power supplies, ISA cards, VLB cards, early PCI stuff, smaller drives, controllers, etc).... that people are looking for... let me know... I'd hate to throw something out that someone would want... but I'm buried in too much stuff. The dumpster may be here as soon as next weekend. Local pickup is free (with donations/trades appreciated). If I have something you want and I have to ship it, I'm going to want $5 to $10 (to cover materials/time/gas) + actual ship cost. I can't even begin to cover adequately what I have here.... if ppl don't come up with enough 'do you have any XYZZYs ?' I'll try to make a list of the stuff (but it will be far from complete). -- Curt

SCSI to IDE bridges... (and useful info for PDP-11 users)

by tiggerlasv＠aim.com

I have used the Acard AEC-7720U SCSI <> IDE bridges. Thusfar, I have tested them with a few different brands of IDE drives; a Caviar 2100, a Fujitsu MPA3026AT, and a Samsung SV04232A. I have also used various sized CF cards, hung off the appropriate adapter. During my testing, these?were attached to a PDP-11, via a number of different Q-bus SCSI?controllers: CMD CQD-200/M CMD CQD-220/M Dilog SQ706A Emulex UC07 All performed similarly, and I had no trouble?formatting and using the attached IDE disks and compact flash cards. I don't pretend to understand the internal workings of the bridge card, but it appears that the bridge auto-detects the capacity of the IDE drive, and?translates that information to the SCSI side. I don't know if there is any limitations to the size of the IDE drive used; my testing was under RSTS/E, hence I couldn't use anything over 2.1 gig. (Some older IDE drives support a 2.1-gig clip, which works well.) Your mileage may vary. If you don't need alot of storage, they do have these available on-line: http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=360087484205 That at least eliminates the additional?IDE <> CF interface, and makes for a smaller form-factor.? There are less expensive models floating around on e-bay, if you look carefully. For those with deep pockets wanting a one-piece solution to SCSI <> CF, there is also this little puppy: http://www.reactivedata.com/3-SCSIBridgeEmulators/legacy_scsi.htm As info. . . . T
