The last entry that lists anything at all for 1977+ only goes as far as 1980. If there a URL that lists more of that period in the wayback machine, I've somehow managed to miss it. Antonio

Dec Rainbow

by trestivo＠concentric.net

Mike, If you need a working vr201 for your rainbow let me know. I have quite a few of them and will sell you one for $25. Add $5 if you also need the cable. (you pay shipping from florida or pick it up). I have working Decmate III's as well and I think I may have the hard drives that go in the rainbow along with the dual floppy unit. I also have some original rainbow software. You can email me at trestivo(a)tarinc.com. Regards, thom

Keyboard key labels

by ian_primus＠yahoo.com

Ever notice that on modern keyboards, the letters on the keys are not in the middle of the key? They are off to the left. This is something that has always kind of annoyed me. I like the way the older keyboards were made, like on the VT100 terminal. Not only did they have real switches and a great feel, but the letters were right there in the middle of the key, where they should be. Not only that, but the labels on these old keyboards actually went all the way through the key - it was made of two different colors of plastic. This way, the letters wouldn't wear off. It's obvious why they changed the key switches - to make the keyboard cheaper. That and some people are weird and don't like the wonderful sounds that the older keyboards made. (I hate quiet keyboards...) But why were the letters moved? Was this cheaper or easier? Or did Apple suddenly do it and then everyone else followed suit? <grin> Does anyone know what computer started using this style of keycap labeling? Just curious. Ian Primus ian_primus(a)yahoo.com

Old Tech - Sort of

by cmcnabb＠4mcnabb.net

Well, my Pentium II motherboard bit the dust the other day (Thank You American Electric Power!), so I went to the local computer parts store in search of a new one. Being somewhat of a vacuum tube fan, I settled on the AOpen AX4B-533TUBE board. Yes, this one has a vacuum tube. It uses a dual triode (Sovtek 6922) as the audio amplifier. The board also sports a 1.5Ghz Pentium 4 and DDR SDRAM, along with the usual bells and whistles such as LAN, Serial, Parallel, etc. The audio out of the board sounds great, as long as you make sure you have the right impedance speakers/headphones plugged in. My normal 8 ohm headphones were badly overdriven, but plugging the computer into my guitar amp (sounds weird, don't it?) delivered that nice, wide vacuum tube tonality that normal sound cards just can't deliver. I really gotta hand it to the guys at AOpen for delivering a wonderful mix of new and old tech. I do, however, really need to install a window in my case so I can bask in the warm glow of the vacuum tube. -- Christopher L McNabb Operating Systems Analyst Email: cmcnabb(a)4mcnabb.net Virginia Tech ICBM: 37.1356N 80.4272N GMRS: WPSR255 ARS: N2UX Grid Sq: EM97SD

Poquet PC

by lgwalker＠mts.net

Nice. Virtually identical to the Sharp PC 3100, but the Sharp had proprietory 10pin RS232, 20pin Parallel, and fdd sockets. It ran an 80C88 at 10mhz as opposed to the Poquets' 16mhz. Only type 1 PCcard slots as opposed to the Poquets' type I/II. Uses 4 x1.5v cells. Based on the specs I think the Poquet wins out. But a later machine. These guys have the PC 3000. About the same price. http://www.notebooksplus.com/pc3000.htm This guy has done some amazing things with the 2MB PC3100. http://www.geocities.com/SouthBeach/Strand/3387/pc3story.html Lawrence > Back in the mid-90's I kept a Poqet PC in my bag or desk to use as an > ad hoc console terminal for data center gear.

Poqet PC

by classiccmp＠crash.com

I've muddied the waters a bit... The link I included was for the later Fujitsu Poqet PC Plus. Fujitsi bought out the original company before or while the second generation product was being offered. CA Digital is giving specs for the Plus model, which is what I believe they're selling. Gee, I wonder if this is covered on one of the timelines people have been discussing... The original Poqet PC has _no_ backlight, uses 2 std AA cells, and MS-DOS 3.3 in ROM. Not sure how much memory is in there, ISTR at least 512K and maybe more. There's a small ramdisk on D: for AUTOEXEC/CONFIG.SYS, and the DOS ROM is C:. The two PCMCIA slots at A:/B: are nice, especially with the 2MB SRAM cards - however I appear to have forgotten to refresh the lithium backup batteries in mine :^} Fred's right, the original Poqet brings pretty much the whole XT bus out to a connector on the back. I like the idea of hooking this up to a backplane... B^P Somewhere I have the docs from when I bought the thing, but it may be years before they surface again. --S.

OS disks for HP150A

I think I may have a museum interested but I would rather donate it as a fully working system.

Modern replica/implementation of a dumb terminal?

No, it is a Hornet chip, but it has an 80C186 in it. Running MSD.exe will show this information. See http://www.daniel-hertrich.de/200lx/block.pdf for a block diagram of the chip, with the 80C186 clearly indicated.

Optical paper tape readers

by kapteynr＠cboe.com

I have a optical paper tape reader called a "TPR-1" connected to my Altair. We bought it as a kit. It has a pretty blue box that matches the computer. It uses a standardized part that has phototransistors spaced correctly to read paper tape. The sprocket hole also has a phototransistor that is used as the clock. This is how we always loaded Altair Basic. I saw the manual a few days ago. I'll see if I can scan it. -Rob -----Original Message----- From: cctalk-admin(a)classiccmp.org [mailto:cctalk-admin@classiccmp.org]On Behalf Of Andy Holt Sent: Wednesday, November 27, 2002 1:34 AM To: cctalk(a)classiccmp.org Subject: RE: Optical paper tape readers Another problem with building a paper tape reader is to ensure that the light source is constant - in particular that it does not vary with mains frequency!

HP 2784B Paper Tape Reader on ebay

by glenslick＠hotmail.com

Speaking of HP 1000 diags, I recently acquired a set of HP 1000 diags on six DC100A tapes, along with a few inches of docs in a couple of binders. I would list the part numbers on the tapes but I don't have them in front of me right now. Each tape contains the configurator file and then several module level diagnostic files. Unfortunately the tapes are 20+ years old and the oxide layer has lifted off in a few spots and I haven't been able to read them successfully. Does anyone the full set of HP 1000 diagnostic files that they would be willing to share? I do have one diag file on paper tape. That was why I was interested in acquiring a reader. >From: "Jay West" <jwest(a)classiccmp.org> >Reply-To: cctalk(a)classiccmp.org >To: <cctalk(a)classiccmp.org> >Subject: Re: HP 2784B Paper Tape Reader on ebay >Date: Tue, 26 Nov 2002 16:49:13 -0600 > >The 2748B paper tape reader is a very nice unit.

One way would be to get some Perspex (Lexan/Plexiglass) rod and make some short light pipes, and fan them out to get the spread you need. Or make some kind of 9-partition screen out of thin sheet metal, narrow at the top and wider at the bottom where the detectors are. The detectors don't have to be right up against the tape, so long as you don't get light from one bit affecting the detector for adjacent ones. -- Pete Peter Turnbull Network Manager University of York

Modern replica/implementation of a dumb terminal?

by classiccmp＠crash.com

Back in the mid-90's I kept a Poqet PC in my bag or desk to use as an ad hoc console terminal for data center gear. Wasn't as convenient as the then current HP palmtops, but a heck of a lot cheaper and an easier keyboard if the HPs were a tad small for you. MS-DOS in ROM supported Kermit nicely for ANSI terminal emulation. California Digital (not the newbies that bought VA Linux' hardware operation) still has them, though perhaps a bit (ahem) overpriced: http://www.cadigital.com/poqetpc.htm --S.

Optical paper tape readers

by dwightk.elvey＠amd.com

Hi I have an old Intel tape reader ( I think it was made by REMEX ). It was a parallel output. I took me about 20 minutes to make an adapter to plug into the bi-directional printer port on my laptop( it took me longer to buy the cable since I went to Fry's to buy it). I took me another hour or so to look up the info on the parallel port to write a simple reader to take input from the printer port to a file. I started without schematics or docs on the reader, just knowing that it was parallel. One should be able to find the output strobe and data lines with a logic probe ( although I used an oscilloscope ).
