When did double-shot keytops disappear?

by cclist＠sydex.com

I was looking at a not-very-old HP keyboard today and noticed that the lettering on the keys is wearing away after only a few years of use. Another corner quietly cut, I suppose. Used to be that keytops were double-shot molded, with the lettering all but indestructible. Is this a practice that's gone forever, or is there still a vendor who makes keyboards the old way?

=== Miniscribe disk drive infos ===

by tpeters＠mixcom.com

Oh my heavens, I don't think I am any sort of expert, but will try to help. Do you have a document for the controller card? If not, I will try to find my copy. Yes, most RLL drives can be formatted to lower capacity and used on a MFM controller, but some aren't reliable when used that way. I don't know which are. What happens when you start the formatter in debug? Does it attempt the format and light up the drive or fail immediately? Do you have any other old PC or XT machines you can try this in? 1701 is a generic hard disk failure code, but it could imply that the bios is set incorrectly and just doesn't recognize the drive. Shouldn't stop you from formatting it, but then again, perhaps you don't need to, maybe you need to fix something else that is wrong. A cabling issue perhaps. The reason I ask about another PC is that I seem to recall the PS2 needing a diskette to configure it, whereas an XT or clone wouldn't. -T At 01:45 PM 12/21/2005 +0100, you wrote: >Good morning Tom, > >I've just read a topic on the cctalk mailing list in which you seem to be >en expert in old MFM/RLL disk drives. > >I get many troubles in trying to place a WD disk controller with a >miniscribe 8438 disc.

GPL or BSD: What license do you prefer for the MSCP SCSI project?

I would say use whatever license suits you the best. If you aren't concerned about someone building a closed source product out of it, BSD is fine. If you do have some concerns, LGPL is a good comprimise. It allows people to link it with non-GPL code without allowing them to close the source. If you want it, and any product linked with it to be made open source, the GPL is the way to go. There are plenty of shades in between. Were I the developer in question, I would probably go with LGPL for a driver or library and full GPL for a program. I've seen too much open source work go into closed source products to use BSD license on my code anymore. But YMMV. Choose what's best for you. Eric

Need BIOS setup utility

by doc＠mdrconsult.com

I'm foozling with a portable 386 system that keeps coming up with an "Incorrect Setting In BIOS" error. I've replaced the battery and tried the several DOS-based CMOS utilities from Simtel, but the error persists. Part of the problem is that this is a Taiwanese clone and the motherboard bears *no* manufacturer or model info. The only badging at all is on the front, which says "LCD 386". It looks like a fairly standard motherboard, has a Seagate ST-251 and a NewTronics DSDD 5.25" floppy drive, 8-bit EGA (I think) graphics card with an internal connector to a 640x240 mono LCD. The keyboard seems to be a regular AT type, clips on the front of the case over the LCD. Dimensions are about 12" tall, 17-18" wide, and 9" front-to-back. I've also never seen a system come up with BIOS messages from two companies: Phoenix 80386 ROM BIOS Version 3.06 Copyright (c) 1985,86 Phoenix Technologies Ltd All Rights Reserved CHIPS AND TECHNOLOGIES AT/386 SYSTEM SOFT SETUP VERSION 1.12 BANK 0 - 1024K NON INTERLEAVED 256k DRAM'S, 0 WAIT STATE MEMORY BANK 1 - 1024K NON INTERLEAVED 256k DRAM'S, 0 WAIT STATE MEMORY BANK 2 - DISABLED BANK 3 - DISABLED AT BUS CLOCK SOURCE - CLK2/2 I can't find any useful info on Google about the C&T "System Soft Setup". My questions are, should I be trying to find a Phoenix setup utility or a C&T util? Am I correct in thinking that's a disk-based utility, rather than NVRAM? In other words, should I be hitting Ctrl+Alt+Ins or something at boot? (Already tried that and all the usual suspects, no love.) Any help or information would be appreciated. Doc

Contextual reference for mainframes/supercomputers?

by legalize＠xmission.com

OK, there are lots of sites that put things like mini and microcomputers into their historical context with photos, hardware and software descriptions, etc. What is considered the best reference for mainframe like machines? For instance, anyone want to bid on a Gould Concept/32? <http://www.dovebid.com/assets/display.asp?ItemID=tbd155271> Opening bid is $1.00, sale ends 12/30/06 from Boeing in St. Louis, MO. Well, sounds *dirt* cheap to me, but I know f*ck all about Gould computers other than the University of Utah bought one at one point in the 90s. (I don't even know if they still have it.) Suggestions anyone? Comments on "DoveBid" are also welcome; I only found out about them today. -- "The Direct3D Graphics Pipeline"-- code samples, sample chapter, FAQ: <http://www.xmission.com/~legalize/book/> Pilgrimage: Utah's annual demoparty <http://pilgrimage.scene.org>

IBM Thermal Conduction Module and 3084 chip offered

by innfoclassics＠gmail.com

I thought I would mention it to the list before posting it on ebay. I need to go to the dentist in January. I am going to part with my last IBM Mainframe 3084 chip. It is still encased in its original Thermal Conduction Module.Chip looks similar to this. http://www-03.ibm.com/ibm/history/exhibits/vintage/vintage_4506VV3121.html The IBM 3084 mainframe is this: http://www-03.ibm.com/ibm/history/exhibits/mainframe/mainframe_PP3084.html As a collectable I think the Thermal Conduction Module is much rarer than the 4" chip. IBM classifies it as one of their most important developments. The chips were saved or scrapped for their very high gold content. The thermal modules were copper based with aluminum plungers and quickly sent to scrap. http://www-03.ibm.com/ibm/history/exhibits/vintage/vintage_4506VV2137.html Here is some information on the development of the Thermal Conduction Module. http://www-03.ibm.com/ibm/history/exhibits/mainframe/mainframe_intro3.html This is a thermal Conduction Module that has never been opened. From reading it is filled with helium so I have decided not to crack it unless I absolutely have to for pictures. It came from a IBM 3084 we scrapped in 1993 or 94. The chip inside is similar to one I sold on ebay last month, pictures in the ebay listing would be similar to the chip inside this module. http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&item=8727630848 Asking $1200 domestic shipping included. Always open to offers. Paxton -- Paxton Hoag Astoria, OR USA

Early 3.5" Floppy Drives (3.x on DEC Rainbow)
