non-existence of printer collectors...proven wrong

So let's say they're just not for the faint of heart ;) I for one have to plead guilty of printer packratting, having piled up an assortment of impact matrix and laser printers mainly (I'm less fond of inkjets because they always clog up if you don't use them regularly). So let's see what's around here: Pin impact: Commodore MPS-802 (first printer in household) NEC Pinwriter P2200 (printer of our first PC) NEC Pinwriter P6+ NEC Pinwriter CP7 (four-zone ribbon color printer) Epson LQ100 (neat little dot matrix unit, even used sometimes) Epson LQ-570+ Epson LX-400 Epson TM-267IIB (serial receipt printer) Oki Microline 591 Star J120 Inkjet: Canon BJ-10sx Canon BJ-20 Canon BJC-85 Canon BJC4100 HP DeskJet 660C (first color printer of my dad) HP DeskJet 1200C HP DeskJet 1600C(M), 3x (professional inkjets with drier lamp) Epson Stylus COLOR (nonstandard appearance for an inkjet) Lexmark Color Jetprinter 1000 (modern exterior) Lexmark X1160 (USB Scanner/printer combi) Laser: Citizen Overture 106 Apple LaserWriter II NTX Apple LaserWriter Pro 630 Epson EPL-5000 Epson EPL-7100 HP LaserJet Series II Siemens PT10 (rebadged HP LaserJet II) HP LaserJet IIISi HP LaserJet 4L (unusually flat laser) HP LaserJet 4 brother HL-1260e (the only one regularly in use; same engine as LJ4) HP LaserJet 4Si (honkin' big cube) HP LaserJet 5L HP LaserJet 6L HP LaserJet 2100M Kyocera F-1200 Thermal transfer Okidata unit with c/y/m/k transfer strips chained in a ribbon cassette two Mitsubishi still image printers (CP100E, CP250E?) with TTL, VGA, RGB and composite video inputs in addition to parallel ...and probably some more buried somewhere that I don't yet have in my inventory. People keep telling me I have to cut down on such stuff (as well as commodity PCs) but whenever I start to think about which to throw out, I get to think about each one's unique features and what I would say if somebody asked me tomorrow if I had a printer for that-and-that specific location and application. One of my yet unfulfilled dreams is a daisywheel printing terminal (Diablo 1620 or similar). Enough of a confession?

At least looking back and when you will be doing short printouts on a classic computer. When you had to listen to it all day not so good. Way back in college they had a 9-1/2 DEC line printer drum/band on an old PDP-11. That would be about the right size to make a nice addition to my collection. Never have seen one like that since then and don't know what the model was. Whenever I find a DECwriter II (or unlikely I) within a reasonable drive I will add one of them to my collection. Do have a DEC dasywheel, a couple of dot matrix PC printers, and an ASR-33

Zenith Data Systems Terminals at U of Washington auction 2/2/08

Hacking away on Pascal programs on H-19 terminals in the H-19 editor at two-thirty in the morning in the ACC...the vending machine that dispensed rhino piss they claimed was tea. Oh, those were the days. H-19 was the first screen editor I ever used, though I never did get used to the "colour" command system they introduced in later years. Bah, the old system worked fine, why did they hafta go and change it? -Bobby

I propose to make the journey in 1973...

by pichotjm＠free.fr

I had the opportunity to conduct a series of photographs when I participated in the fair 'Le Bourget' in 1973. You will see about 200 original pictures of displays, keyboards, computer terminals, cameras, radar displays, screen shots of weather, tactical, electric power plant, road traffic, and 8 american or soviet satellites. The visit is here: http://pichotjm.free.fr/Techno73/Techno73US.html The root address http://pichotjm.free.fr will lead you in early computers... (1954 to 1975) Enjoy! JMP

I brought this topic up as a thread on vintage-computer.com/vcforums. I keep one printer per system type in operational condition, and use them for comprehensive testing of systems. Same goes for modems. I think that the Diablo printer is worthy of collecting (I have an Commdore-branded OEM model CBM 8300P, which is quite rare I believe). A nice IBM Proprinter is worth holding onto. Boxed printers are easy to store, I prefer printers in their original boxes, otherwise I am less likely to keep them. Bill D

The pickup roller is $1.00. They have replacement parts for all sorts of laserwriters and have presence on many sides of the pond. Good folks - just a very satisfied customer... CRC

I tend to like the better printers even if you do have to put some $ into upkeep. I made that decision after cursing out a cheap printer that would have "issues" often.

The only printers I accept in the >house are Postscript because anything can talk to them. Me I have a HP 4L, Epson LQ5000 for the parallel interface printers that speak basic ASCII as well as other protocals. I may have a MX80 as well. For the serial interface printing camp a pair of LA100RO. Not all of my systems speak postscript, they all speak ASCII. Allison

Proper spacebar repair on XT 83-key?

by trixter＠oldskool.org

The spacebar died on the last working 83-key XT keyboard I had (I have three, and ALL have non-functioning spacebars), so I decided to finally choose one to take apart and try to clean with compressed air, etc. All of the keys came off okay; I put the plastic parts *only* in the dishwasher (mild soap, warm water, nothing harsh) and cleaned the rest by hand by shooting compressed air into every buckling spring hole. But when it came time to put the spacebar back on, I noticed that both ends of the spacebar have two little "hooks" that are supposed to hook onto two little prongs of metal underneath the top of the assembly. These provide necessary support, as the spacebar will bend if pressed at the edges instead of going straight down. Only problem is, I can't seem to get these re-hooked! The only way I can see getting the spacebar back on, barring some trick I don't know about, is to take the metal back off the assembly and try to re-hook it from underneath. But I'm terrified that, if I try to take the back off, 83 buckling spring assemblies are going to fly every which way from the unit and I'll be left with a worthless hunk of junk. It also doesn't look like it was meant to be taken off anyway, as one of the metal tabs on mine seems intentionally bend downward to prevent this. For those who need pictures, I've taken some snapshots of the problem and put them here: ftp://ftp.oldskool.org/pub/misc/keyb/ Any advice is appreciated -- either that, or a source for more 83-key XT keyboards... -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Help our electronic games project: http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/ A child borne of the home computer wars: http://trixter.wordpress.com/
