    Love to see you caring about all these animals!
    LA50: the printer of "my dreams". My father worked for DEC in the 80s/90s as technician and printed all his reports at the evening at the home office on such a device. I often felt asleep with the sound of the needles, two doors away from the office. A noise, I will never forget and never hated. It more gave me the feeling "there is anybody taking care about you".

      The LA50 is such a nice, tight little printer, it was a joy to get it up and going again. And the sound of that dot matrix print head is something I haven't heard in a long while as well. I'm glad I could get some feelings of nostalgia going with this little video!

    The second I saw that, my fingers instantly went into muscle memory to operate the thing, remove lid and change paper,, reassemble and hit the go button. I used and serviced these a LOT in the 80s. Fun fact, it's the same mech as used by the Apple printer that matched the Lisa, made by C.Itoh as the 8510.

      Man, i was going to reference and old 9 pin printer that used a typewriter ribbon and had a cast aluminum housing. I want to say it was an Okidata, but i am not sure. But those things will probably still be printing when the cockroaches inherit the earth. And on the original ribbon, it will just be printing faintly.
      Heck, i remember repairing "paper tiger" printers back in the 1980's, those things were beasts too. As long as you didn't mind replacing the occasional darlington pair transistor.

    I had this setup in 1985 in business school. I remember a magazine review article saying "If you prefer all your equipment to be from one vendor you are in luck because the only driver that Lotus 123 provides for a Dec Rainbow is for a DEC LA50 printer". See, it's a FEATURE!!!.
    Oh and the next time you have the cover off the rainbow, notice that you can rotate the square logo panel next to the power switch for when you stand the computer on end in "tower" configuration. Some engineer must have been really proud of that.
    I also drilled a little hole in the filler panel for the second drive bay so that the hard disk's activity light could be seen. Real hacker stuff there.

    When I worked as a printer repair tech. I was told never to use wet lubricant on the print head bar. You'll get dust from the paper and the ribbon settle on the print head bars. This will gum up the bronze bearings on the print head sled.and cause the print head to seize.

    This is like seeing an old friend. Long ago I had picked up three of these, bought from a fellow who had got a whole palate of them at an auction in Albuquerque. They are Japanese in origin, made by C.Itoh company. Same basic unit as the C.Itoh Prowriter. In fact, many of the parts interchange. I had bought one as a parts unit for the Prowriter. Main difference was the Prowriter has a Centronics interface, the LA50 is serial. The firmware is different as well. The LA50 was so versatile, made cables that allowed it to tap into any serial data stream and print whatever was coming down the line when toggled on.

  • @mikefochtman7164
    @mikefochtman7164 11 หลายเดือนก่อน +10

    Been years, but I think the 'COM' port on the printer was so it could be tied to a modem (which is why maybe it was set for 2400 bps). That port would have pinout for DTE ('Data Terminal Equipment') instead of DCE ('Data Communication Equipment'). Early days, DTE/DCE was widely considered the 'proper' way to wire. Later we just ended up throwing a 'null modem' between things when you needed to rewire.

    • @ChristopherHailey
      @ChristopherHailey 11 หลายเดือนก่อน +1

      That's exactly why the different genders on the plugs, they used to do that to show what was wired for DTE or DCE. DEC terminals allowed you to print the screen or log the screen output to the printer or the host system could control the terminal to direct printouts to the printer without needing a second line to the host (you had to finish the print before using the terminal again)

    Ah, dot matrix printers. Growing up, we had an Imagewriter II attached to our Apple ][c+. Noisy little thing, but nowhere near as ear piercingly loud as the high speed wide carriage daisy wheel we had attached to an IBM XT. The Imagewriter II was noisy, but you could still be in the room with it running. The daisy wheel, that one you'd start the job, leave the room and close the door! LOL

    I have an LA75 sheet feeder attachment. Those seem to be extremely rare. I’ve never seen a sheet feeder attachment for the LA50. I do remember some students in college feeding single sheets one at a time to print college papers off the PDP 11/70 mainframe using a program called Runoff. We would use a regular text editor like EDIT or TECO and incorporate the dot “.” commands for formatting information. On the Rainbow (much later) there were some more advanced word processing programs. Our Rainbow at a place I worked had a DEC Daisy Wheel Printer attached for letter quality output. The LA75 had several print speeds with the fastest being bare dot matrix and the slower being called near letter quality. There were some escape codes that would work on the LA50 to do the same thing.

  • @jasonknight1085
    @jasonknight1085 11 หลายเดือนก่อน +2

    1200 7n1 most likely means it was connected to an older mainframe. Realistically for most computers prior to about 1984 anything over 1200 baud was a pipe-dream the hardware couldn't actually handle. Likewise the 7 bit with no parity gave a slight (1/9th) speed boost. One also has to remember a lot of older devices only had six bit character spaces, thus requiring either an interchange box to turn it into 7 bit ascii (most of which could NOT handle anything past 1200 baud either)
    I remember replacing a LA50 at a jobsite in the late '80's with a daisy wheel because they were wasting an entire 5150PC as a middle-man just to turn DEC sixbit into ASCII (praise be the XLAT instruction?) and the older daisy wheen supported that native.
    Realistically in most cases the parity bit was only needed if you were in a noisy environment, or you were pushing the baud rate past either device or the wire's capabilities. The moment we hit 2400 baud and faster as commonplace that parity bit basically became a "must have" until cable and hardware caught up.. though also a lot of older serial devices couldn't even spare the computational power to calculate a parity bit. There's a reason 8n1 prior to about '83 really wasn't a thing, but afterwards ended up becoming the norm.
    I even had that issue at home with a Roland plotter (I got from a dumpster dive), where I had a choice of 300 baud at 7E1 or 600 baud at 8n1 trying to get it to talk to my Coco with its funky four pin DIN serial.
    But all this dicking around with baud rate, parity, and stop bits makes it pretty clear why for printers Centronics parallel ended up the winner. Well, unless you needed to run the cable a couple hundred feet.

    Back around 1980, I updated by small legal office into the new age of personal computing. Being pre-laser printer, we printed on dot-matrix printers like this one. I had a small one, name forgotten, for personal use, but the "big gun" was made by NEC. It was large, fast, and robust beyond any expectation. It also screamed when it printed. It was so loud that we put it and its computer in a separate, sound insulated room. Even then, its noise was intrusive through most of the office.

The NEC 5500 (memory could be faulting me) had a lot of issues with bad duel op-amp chips, otherwise it was a pretty good printer. Later Okidata was the king, and we sold a lot of those.

    Lithium grease is the standard lube for printhead rails, so you guessed right! You can recondition the roller by 'scrubbing' it with a rag & acetone (nail polish remover or laquer thinner work fine). IMPORTANT! You need to take out the roller to work on it, because acetone will ruin plastic parts! I have reconditioned rollers in situ when it's been impractical to remove them, but you have to be extremely careful.

    I worked a lot with these printers in the early 1990s. By then I always had a box of adapters for printers and terminals with 9 and 25 pins as the cabling itself was with done with RJ-45 like cables.

    The printer looks just like an Apple Dot Matrix Printer (aka the DMP; "Dot Matrix Printer" was literally the name of the printer, not just a generic description), which itself was a rebadged C.Itoh 8510. The DMP (and, I believe, the 8510) was a parallel printer.
    Apple later released the original ImageWriter, which had a different exterior but the innards were still the same or at least substantially similar, although the ImageWriter was a serial printer. Even later Apple produced the ImageWriter II, which had a completely different form factor and an updated mechanism.
    Other than perhaps a few Apple-specific control codes (e.g., the color codes for the IWII), I believe they all used compatible control codes.

    That clear plastic over the dip switches takes me right back to being a 5 year old as the MX-80 printer looked like that inside! I knew those were the forbidden adjustments, but only that.

    The Ready Switch is because this printers were normally controlled by a spooler in a multi user envoironment. While you do some work on the printer like changing the colour tape or the paper, you make shure no job is executed, and the spooler stores the jobs until you are ready and press ready 🙂

    Dec and Apple used same printer "engine" from C. Itoh. LA50 & ImageWriter with later work with other PC's C. Itoh 8510 drivers. LA75 & ImageWriter II. HP and Apple used same thing with first 2 versions LaserJet & LaserWriter. All with different cases and logic boards running them with many mechanical parts could interchange between brands.

      Yeah, that might be why the low baud rate set on the printer. I remember doing that back in the 1980's when I couldn't get the manual for some micro-mini (8 users on 64K of ram!) - just used the simplest RS232 and slowed everything down so the printer never overflowed... it really wasn't noticeably slower and they ran like that for years.

      Of *course* it uses the same ribbon, Apple's printer mechanisms of the era were all made by C. Itoh, just like this "DEC" is a rebadged unit with a different sticker, the same as the original Apple DMP (with different ROMs for the Apple character set, etc.) The ImageWriter was also made by C. Itoh, and then the Imagewriter II used a C. Itoh mechanism inside a chassis built by Apple.
