I'm trying to find information and/or a controller card for the Plus Passport. Plus (Plus Development Corporation) is the same company that made the Hardcard. The Passport is a removeable drive chassis. You install the chassis into your PC and then the hard drive modules slide into it and connect to a connector on the back end. You boot the computer, do your work, then when you're done for the day you slide the hard drive out and take it with you. I've got the chassis but need the interface card and/or any drivers that it may have required. Has anyone ever heard of one of these things, or used one, or have what I need?

They would be the same if one only connected the points of the three phase. The problem is one often ties 120V stuff between on of the legs and the neutral center of the Y. If one has three balanced 120V, everything is OK. If not, one will have all the voltage drop and bang! Dwight

Gordon Bell's Computer Structures: Readings and Examples book is online!

by esharpe＠cox.net

was going through some books to add to the reference library here at the museum and ran across a most excellent book Computer Structures: Readings and Examples by Gordon Bell..... has the inside facts on many early system and even the 9100A HP calc. also to my surprise I found it online at the below listed url. http://www.research.microsoft.com/~gbell/Computer_Structures__Readings_and_… If you have plesnty of disc space you may want to archive it in case this link ever goes away.... Happy reading! Thanks Ed Sharpe archivist for SMECC Please check our web site at http://www.smecc.org to see other engineering fields, communications and computation stuff we buy, and by all means when in Arizona drop in and see us. address: coury house / smecc 5802 w palmaire ave glendale az 85301

Apparently one order is more common than the other, and we use the "uncommon" one, but I can't remember which is which. -- Pete Peter Turnbull Network Manager University of York

O(ff)T? or O(n)T? 22DISK on a PC

The problem of having DOS and Windows coexist. It might be OK with XP, which certainly coexists happily with earlier versions of Windows; I don't know if that extends to DOS but I'm sure I'd find out quite quickly if I tried it :-) If I do I'll let the list know in case it helps anyone else who needs an environment for retro software/hardware. > Currently I triple-boot the desktop PC between Linux, Windows 2k and DOS > 6.22 - but I'm using SCSI disks, so Linux and Windows co-exist on the > larger drive and DOS has a seperate drive all to itself.

Yes, it's called a DPDT switch ;-) Or you can just use a boot floppy. > As an aside, I'm curious as to what (if any) equivalents to 22disk there > are for Linux.

I've not seen anything and in fact last time I looked at Linux's support for non-PC formats, notably anything that started it's sector numbering at zero as %deity intended, it was sadly lacking (but that was quite a while ago) > I have no idea what sort of control the kernel headers allow you over > the floppy controller(s) though.

I'd use teledisk for disk images, as people seem to use that much more often. -- Pete Peter Turnbull Network Manager University of York

Lodging for VCF East 2.0

by vcf＠siconic.com

I've arranged lodging for VCF East. I've got a room block reserved at the Marriott Burlington. $69 a night if you pay in advance (no cancellation/refund) or $79 a night if you just reserve in advance. It's a pretty good deal, considering this is a 3-* facility with internet access in each room (I don't know if there's an extra charge for that, but probably). It's also within walking distance of Sun's campus. More information is here: http://www.vintage.org/2004/east/lodging.php I'm sure there are other cheapie hotels in the area but you'll have to find them yourself. A good place to start is to go to Yahoo! maps, put "Network Drive" in "Burlington, MA" into the search box, and then click on the links to find local hotels. -- Sellam Ismail Vintage Computer Festival ------------------------------------------------------------------------------ International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]

O(ff)T? or O(n)T? 22DISK on a PC

by pete＠dunnington.u-net.com

I've put off asking about this in view of the discussion about what's on/off topic, but I need some help from Those Who Know These Things. My specific requirement is to put together a PC to run 22DISK, my DOS-only PAL/PROM programmer software, and the like. It will run DOS 6.22 in a FAT16 partition (and probably WinXP in another partition because I will not permit more than one PC in my workshop, but that part is definitely off topic so I mention it no further). I want it to be able to support single-density floppies, and eventually 8" drives too. Available "ingredients" are an Intel SE440BX motherboard (if it matters) with a P2 400 and stupid Intel/Phoenix BIOS, a Teac FD-55GFR 5.25" floppy drive, choice of any number of 3.5" floppy drives, the usual other bits that go to make a PC, and a few harddisk/floppy controllers, including a Western Digital WD1006V-MM2 F002, and a Western Digital WDAT-240. I have a couple of older no-name ISA floppy cards but I suspect they won't support HD floppies (though I wonder if they'd support 8" DD? Same speed...) and I probably have other 5.25" drives somewhere. I picked those controllers, by the way, because they have 37C65 FDCs and the magic second (9.6MHz) crystals and are reputed to do SD correctly. A problem is the braindamaged BIOS/mobo, which only handles one floppy. Yes, really; not content with bastardising the interface to enable cables-with-a-twist, they've removed all drive selects but one. No pins, no PCB tracks, or in the words of the manual, "no connection". However, if I disable the onboard FDC in the BIOS, I can persuade the machine to see the FDC on a WD1006V-MM2. Only it won't boot; it gets so far and then hangs. It almost looks as if disabling the FDC in the BIOS actually disables support for an FDC at the primary address, and MS-DOS can't complete the boot. Do I need to do something with CONFIG.SYS? Maybe it would be better to leave the onboard FDC alone, and use the WD controller as a secondary? I guess I do need DRIVER.SYS for that, yes? I have a similar problem with the HD controller. I want to use two IDE channels, but I can't disable the HDC on a WD card; I can only change the address between primary and secondary - and I can't even do that on the WDAT-240, unless someone here knows something I don't. But I can't get the PC to work properly with the IDE controller on the WDAT-240; if I leave the onboard controller enabled, they fight, and if I disable the onboard controller in the BIOS, it seems to stop the WD controller working properly. Any suggestions? -- Pete Peter Turnbull Network Manager University of York
