I'm glad that between my brother and I, all of this stuff arrived intact! Hopefully the 9121 can be resurrected and brought back into service so you can make use of all of that software you've mentioned. As for the plasma displays, they're incredibly versatile, but the protocol to talk to them is more than a little odd. You mentioned pinball displays, but these are roughly double the resolution of a pinball DMD. The driver board that my Dad built to drive the displays was pretty basic and more or less bit-banged the outputs to put text on the screen, among other things.

The plotter would be awesome for a battleship game

That 6-pen plotter brings back memories. My high school drafting class used one to plot our assignments and I loved watching the drawings unfold on the paper, particularly for me, since I spent time ensuring sections were color-coded to make visualizing the parts easier. Exciting Stuff!

Just a little less than 35 minutes of vintage HP equipment? I'm all in!

Your enthusiasm is contagious, fun to watch

Your joy and happiness are infectious when you get something either working or to work on. I very much appreciate these videos. Have a great day!

That plotter should be able to plot 11x17 paper, which would make sense as 11x17 is mostly used for engineering drawings, as a D size sheet scales down nicely on it. Would be cool to make drawing in AutoCAD and being able to print them out in 11x17.

Plotters are awesome. Worked with an A0 one during apprenticeship for structural and civil engineering at the end of the 90s. So cool seeing it whizz around, moving paper up and down, with sub-millimetre precision.

I worked for an HP reseller in the 80's. I used the 7475A plotter to draw maps for games like Zork using HP Drawing gallery. I forgot about the special interfaces on the HP 86A. The 9121 was the first time I used a 3.5" disk. It did not have an autoshutter for the disk. You had to manauly slide the cover on the disk. There was no spring. The newer disks had a catch if you slid the cover on a newer disk.

Mesmerizing watching that beautiful plotter.

I am here for this content. But I'm thinking, have I just watched the geekiest unboxing on the internet. I live your enthusiasm. Love it. X

plotting sideways on an 8 1/2x11 sheet probably means it can also plot on an 11x17 one. back when i was doing that sort of thing for a living, we worked primarily on 11x17 sheets; a plotter that could do that would have been nice.

Yes, I've used these kinds of plotters. They can print on long paper

Wow, what a nostalgia trip to my childhood watching that HP plotter, they use to had one of these at my mom job in Venezuela in the 80s when I was just a child, it was mesmerizing watching that thing grab the color pens and dance along the paper and do all these finely detailed bar and pie charts.

Shelby slowing down time just after the intro! 😂

I just got a Smith Corona 380 XL. It's perfect except for one broken clip but I get to fix that so I'm super happy! Thanks for the videos!!

This just hit me in a special way -- Maybe I need to finally undertake the revival of my HP 87 set? Dual floppy 5.25". One Bering box with 5 MB hard disk & an 8" floppy. One letter size (A) plotter. One B size plotter. Serial port module. [One of the two plotters is serial, the other one HP-IB]. The problems are multiple. The 87 has no doubt leaky or outright blown capacitors. The hard disk did not boot the last time I tried (before the '87 capacitor problem). And plotter pens were rejected for whatever reason. Moreover, they of course are dry by now. But so fond memories...

That opening slow motion spin was breath taking

An alternative to your version of 5x5 is one where the winn condition still only requires 3, even in a grid of 5. It makes it like multiple simultaneous overlapping games and makes cornering territory even more important. That works even with bigger numbers too, but gets more Go-like as you get bigger.

The HP7475A' geneva wheel sprocket that moves the pen carousel, if original, WILL shatter into small pieces. There's a replacement 3d printed model on thingverse - order-it 3d printed from ASA plastic with 100% infill. You will need to use some small files to enlarge the hub hole as the one in the 3d model is a bit too small.

An excellent haul! I do love vintage HP gear - I blame CuriousMarc! ;) I agree completely about shipping CRTs face down. As long as there is some padding to protect the face the chances of survival are much greater.

gosh, the plotter is just so much fun! I would love to see you feature it in future programs and videos.

That Plotter is a thing of beauty!

0:38 slow mo turning was perfect

real ones remember when this channel was called AkBKukU.

playing tic tac toe in a plotter is the nerdiest and coolest thing I've ever seen, winning must feel a thousand times more satisfying lol

the slow motion turn in the beginning is so good lol

I could rhapsodize about my HP-86A endlessly. Forty years ago I learned how to program on it, first the BASIC, then the native Assembly (very different), and finally 8080 Assembly (I got the add-on Z80 module). Though it spends most of its time tucked away these days, I had it out about a year ago and not only did the hardware still work, but all the games and what not I wrote were still readable on the floppies (5.25"). I only have the dot matrix printer; never got hold of a plotter. A few years later when I was writing HP laser drivers for my company, I realized that the that old dot matrix printer used a primitive form of PCL. Ah. You never forget your first love.

I took drafting in high school, and we did the drawings and a drafting table with pencils and rulers the following semester; I no longer needed the credit for the course; they had replaced the tables with Atari STs and CAD software, and I missed it by 1 year. 😁

You could make Connect Four by programming it to add each X/O to the bottom-most free space in each column.

Great video, be nice to see you doing videos down the line into HP PA RISC and their Unix.

It’s amazing! The key colors and documentation are all reminiscent of what was used for my HP-41CV calculator.

That plotter can take B size (11x17in) paper.

Love seeing the plotter actually work! As a kid I wanted one so bad but didn't have enough money. :)

People old enough to remember unpacking new CRT monitors will remember that they were usually packed screen down... 😅 I remember.

I've had two CRTs shipped to me. One was in the original box and etc. So it was very well supported and survived the trip without any issue. The other was... just stuck in a box and got to me entirely destroyed. (Tube itself was fine, but the plastic housing was shattered to bits. Real shame because it's quite a nice monitor too)

On the keycap stems. Try printing them, or rather, have them printed, in an ABS-like resin. I'd offer to do it, but my 3d printer sucks.

Besides hearing a leak song in my head. That monitor is a NEC monitor with HP name on it. I had one with an Apple II plus. Very sharp monitor.

i haven't the foggiest idea what the hell is going on in most of these videos, and yet, here I am chomping at the bit to see what next has arrived!

We had the same plotter in our office back in 1987/88. It‘s not meant for plotting sideways but for the DIN A3 format - which is about 11 x 17“, like @andykillsu says. Fun little machine, I remember it was pretty loud hammering on the paper and the rattling turret.

Fun stuff! I took am diving into an HP computer restoration. It's a prototype laptop that has a Compaq BIOS screen (from right after HP bought out Compaq). Finding drivers has been a bit of a nightmare. I had to manually edit the inf file for the wireless card (802.11b compliant), and am struggling to find Windows XP drivers for the video chip. It's a Pentium 4-M laptop, so Windows XP should be right at home.

I MAY have the HP 13272A floppy drive which the same as the more common 9130A (for HP 86A); but it came with an interface for connecting to HP terminals (I don’t have cables). 13272A floppy had a 40-pin card edge connector (as I remember), used standard TM-100 5.25 inside, but controller card may have been different.

ohhh unboxing cool stuff !!!

Man, pen plotters are so cool..

There is a plotter related to the 7475A called the ColorPro which has no carousel motor- it actually uses the paper feed motor to turn the pen carousel. It also has fixed paper size.

4d naughts and crosses on a plotter would be really cool

I bought a 21" Sun Microsystems CRT on eBay back in the day (one of my first purchases) but it literally arrived in pieces and I never got to use it. 😢

Yeah, all monitors were shipped around originally - it really wasn't an issue. I don't remember if they shipped them screen side down, or in the regular orientation though - I think I seem to recall they were shipped screen side down. Also, all tube monitors are old now, so the plastic is a lot more brittle than it was originally. I doubt packages are handled much differently than they were before - to the shipping monkeys, they're just boxes - they get tossed around and drop kicked, fall off conveyor belts, driven over by trucks, and who knows what along the journey. I've shipped quite a few LCD monitors in the last few years, and never had an issue. It really depends on the packaging. Extra cardboard, bubble wrap, and much sturdier boxes (compared to crappy HD or Lowes boxes like in this video, or crappy u-haul boxes that a lot of people like to use ) are your friends. Even some fruit and vegetable boxes you can get for free at the grocery store are sturdier than the "box store" boxes :)

What a lovely machine! About as compact as it could be then

Not an HP fan as such, but I'm still looking for a keyboard (I used one such on 7000 series workstations) of the rubber/eraser-feel like keytop type. They felt bad when I first started using them, but after a while you wouldn't want to switch them for anything. The softness of the keys made for some very high friction so they wiggled around when you moved your fingertips a little. I have a similar keyboard but the keytops are hard smooth plastic (unless they have morphed as a function of time?) and it is a standard PS/2 connector/protocol.

So the Connells were singing about an HP plotter? The more you know.

was fun seeing that plotter do its thing surprisingly fast and accurate for something that old, i remmember dot matrix printers being painfully slow.

Curious Mark featured something called EBTKS (everything but the kitchen sink). Not sure if it is compatible but you may wan't to look in to it.

Anymore plotters and you will end up like Steve at Mac84 with a basement built out of Laser Writers, well in your case it will be plotters haha 😅

I've had two CRTs shipped to me, but only one actually survived. The first one was shipped in normal orientation and was just fine because it was well wrapped in bubble wrap and foam packing. I guess 12" tubes are more resilient. The second was shipped tube down, buuuut unfortunately the packing was just packing peanuts. No bubble wrap, no foam, nothing to keep it from shifting in transit as the packing peanuts are squished. I pulled it out of box and heard the distinct tinkling sound of broken glass inside the case. The neck was snapped cleanly off. Sadly that monitor was a genuine IBM 14" VGA model that would've gone perfectly with my PS/2 machines. I actually only paid $1 Aussie dollary doo for it, but $70 shipping, which still would've been an amazing deal if it arrived intact. I did eventually get an identical model with an intact tube but dead electronics, but there were issues that I found during reassembly, and I haven't had the guts to try powering it on.

I think you mean GPIB - general purpose instrument bus. And a lot of newer equipment did away with GPIB now - now it's LXI over USB or Ethernet primarily. Same idea though, a general purpose command language that's interoperable across multiple manufacturers, but on a more modern physical layer.

That's some really cool stuff! I'd love to find an HP 150 touchscreen computer, I had one growing up that I got at an estate sale for $10 or $15. I ended up selling it in a rummage sale when I was 18 which I very much regret, especially since it was in really good cosmetic condition, the only issue was that none of the discs worked any more. So if anybody knows where I might find one for a reasonable price let me know!

Never having dealt with HP gear of any sort, how bad is trying to keep all the four- and five-digit model/product numbers straight?

Connect 4 and battle ship are the only games that come to mind for modifications of this program

And here I was hoping it would be something that would run Domain/OS, oh well. :) EDIT: Only twice I've risked buying a CRT and getting it shipped. The first was a C= 1902 which arrived whole buy pure luck since it was shipped almost w/o any packaging, the second was a really cheap VT320 that was really rough. Unsure if the plastic snaps were broken when it shipped but they were when it arrived, however it lives to this day.

In general, however much padding and boxing you think you should have, double it at least. If you ever ship a CRT, it's face down with a ton of padding in a box (twice as much as you think you need), which that box should be inside a larger box with at least 2" of padding between the two boxes. It's gonna cost a fortune, but most of the time, if you do it any other way, it WILL NOT SURVIVE.

A lot of it comes down to the boxes. The boxes from HD / Lowes / u-haul that a lot of amateur people use are absolute flimsy garbage. You need to find thicker boxes that are much stronger for larger / heavier items.

Were those key stems fully cured in a UV curing oven after printing? "As SLA uses resin and not molten thermoplastics, the effect of material shrinkage and warping is much less severe than in filament-based printing techniques. However, that doesn’t mean SLA isn’t without its own deformation issues. The photopolymer will shrink during the UV curing process, and results in wrapped edge, deformation and bad dimensional precision. "Although the resin is cured by exposure to the laser, it does not become fully cured in that brief instant. The material will only reach full strength once it is placed in a UV curing oven during post-processing.

Didn't know UV resin did that, but I think it may depend on the resin.

@oliverer3

It shrinks while curing typically. So if it's left somewhere that is exposed to UV like near a window it will quickly go brittle and sometimes warp. Some resins are just very weak in general though.
