@@curiouscomputer sorry, man. No offense meant. I said it mostly because I'm an old fart. Anyway, wonderful video. Thank you for your amazing work, man.
Low budget indie films have a budget for renting cool props? News to me. (Seriously though, its higher budget titles that have luxury for indulging in cureos like this for the abandoned government project scene where a dormant ai is biding its time)
Being a volunteer at a computer museum, and knowing people who personally have leased out computers as props. This is a BAD BAD BADDDDD idea. Because you know the first thing that will happen? The director will be like "this is the wrong color" Then the computer ends up spray painted poorly. Then its "we want this on the screen" OK time to bust the CRT out and put an LCD in to get what they want on camera. Just to be CGI'd over later... lol. Both of these things have happened. ONLY lease out equipment you think of as scrap. Its the only safe way to ensure you don't end up with scrap back...
Oldest HP minicomputer I interacted with was much later, the 9k series. For whatever reason, building furniture was a thing plenty of computer manufacturers really were keen on back then. Wang had all kinds of expensive desk compute combos up and down the market.
We had some obsolete-as-new Finnish domestic computers in our computer lab in our equivalent of high school, but they were flip-top furniture and re-used as desks for 16MHz IBM PS/2 386SX machines. If one didn't know or suspect, they looked like normal desks.
"This is actually the boot drive and I should really archive it" 💀 But the little laugh you let out after is so relatable lmao Happy to have been recommended your channel, great watch, looking forward to more content!
Thank you for saving this amazing machine!! Many collectors would give their left foot to have something like this at home. Good job on the restoration, too bad the cataract cant be fixed.
This video gives passionate garage tinkering with friends vibes and I'm so here for it! Also, did HP really gold plate ALL the traces of those mask-less cards??? wow
As someone who just started collecting elder computers these past five years, my goal is to slowly start collecting and taking care of even these ancient machines. I loved the video! Hope to see more!
Congratulations, you have a great computer. And thanks for the video, very interesting and educational for those of us who love this type of computer but we have never had access to one. Greetings from Barcelona
Those same desk mini computers were also most likely commonly used in the 1970s and early 1980s in railway control centres so they were very likely in use originally in the Museum/Melbourne Central rail control centre in Melbourne Australia when the underground station first opened in 1981! :)
It is such a beautiful machine; it deserves to be loved, and luckily it has found a new home where it will get the attention it needs. Congratulations, Mutz!
Great video !!! Back in the 80's I had a colleague supporting them full time. I still remember the keyboards were inductive, using small ferrite nuclei passing through pcb printed inductors, and the key codes were programmed into a 2716 EPROM. Good old times !!!
That monitor takes me back. My parents used to work at the HP plant sites in Northern California, and in many of the service areas still had old 70s minicomputers and dumb terminals in use.
I worked for HP's Disk Memory Division during that era. I worked on drives with storage ranging from 60 megabytes to 400 megabytes. Some weighted as much as 340 lbs and sold for $38000. Manufactured as many as 900 units a month for each of 4 product lines.
@@curiouscomputer Unless I wasn't listenin correctly as I was tidying up. The dude using the sound board was your dad no? Family or not, this relaxed behaviour was nice to see in a tech vid.
When I graduated college in 1981… I happened to know Z80 code from my personal Z80 computer. So I got the job to fix bugs in the HP 2622D terminal which was used for the multi-users that connected to this computer. Later I wrote the disk driver for the seagate 5MB disc drive (and yes disc is with a “c” and not a “k” back then :-). This was all over HPIB. Later I pushed to modernize the HPIB protocol that HP used (which was proprietary version of GPIB) to not think of disk drives as head, track sector and think of the disk as sectors from 1 to whatever. That came to play when my next driver was to incorporate a new tape drive to the system. The ergonomics of the HP-250 you have were amazing! People loved to work on that machine. Later HP simplified the system and got rid of the desk. Which I personally hated. If you can find a 5MB platter drive or a 5MB Seagate drive with interface your system will benefit. Oh and those boards were all gold plate. Lastly the processor was using a process called silicon on sapphire a process that was pioneered at HP and built in their labs on Arques in Sunnyvale, CA… A campus that I worked at. I love that you shared your discovery of this computer. We would often use a pencil eraser to clean the contacts on the edge connector…. I’m looking forward to watching your journey in discovery of this machine.
It's even heavier than an old Sony Trinitron. You could probably surprise a young person by telling them there were TVs that weighed over 300 pounds. (Bing tells me that's over 136 kilograms which I didn't know since I'm an American.)
Long ago I had a HP250 like yours, except I had a 15 megabyte hard disk instead of multiple floppy drive. I loved the keyboard, never found one as good.
Fascinating, a lot of of visible gold present also, but who would scrap that treasure, someone that worked on this is probably still alive, I hope they see it. Great video, ty
It's astonishing what people throw away, what a lucky find! A very cool looking design, interesting that they made the computer be an actual desk. Making consumer tech into furniture was very common last century with console TVs, radiograms, gramophones, and the ubiquitous Singer sewing machine, I didn't know that extended to commercial equipment. I'm surprised the tambour door over the floppy drives has remained intact. I imagine the desk shape might have proved a headache for some people when trying to fit it into an existing space, or wanting to remodel. I wonder why that aspect ratio was chosen for the monitor? It's very wide and low, sort of like the view of a page you'd get on a typewriter.
Just stumbled upon your channel. Really enjoy the content. Nice overview of this machine. Look forward to future videos on removing the cataract on that screen
Oh my God, my first computer station as a young person was an HP station almost identical, oh do I remember 8 bit days the 8088s and 8086s... That is such an awesome retro project!
My stepdad had one of these. We literally just used it as a desk for the "family" 486 computer for a while. I was told not to touch the HP b/c everyone thought it was a fire hazard for some reason. But I remember when I was 9 I woke up at 2am and figured out how to turn it on with a butter knife. Tried punching in some no-graphics Atari games from a magazine one of my friends had. Good times. It still makes me sick that it just disappeared one day while I was at school because I couldn't let anyone know my secret.
Love vintage HP computers and gigantic “mini” computers, owned/own several (Apollo DN460, Altos ACS8000, SGI 4D/780GT, California Computer S100 thing) but always thought a vintage desk-computer would be just cool to have. Never found one but I do have two desks with integrated rack mounting for servers so….almost.
Growing up and using computers like the C64 and like an IBM XT, I thought I had quite a bit of experience with old computers, but I had absolutely no idea that computers like this one existed, or that floppy disks got that big. The biggest I had seen were the old 5 1/4. For you to have so much knowledge about this machine is amazing. I can't imagine it's all that useful by modern standards. But it's still very cool, the amount of work they put into it with the sliding panels and drawers to access the system is something you don't often see. This definitely belongs in a collection somewhere. Though it's funny the title says minicomputer when it's pretty large, though I suppose compared to computers at the time it was rather small. I mean it's not taking up a whole room.
I had an older friend when I was an HS student who was one of those techy geniuses. He spent most of his time in the mainframe basement of the local university and had a set of 12? 8? I dunno, with the corners bent up. He'd go out into a field after sunset (wasn't a big fan of daylight) and toss them like boomerangs. I can't remember the capacity, probably embarrassing by today's standards.
I'm rocking my next LAN party with an integrated recording studio DAW from 2000. But on all original hardware. I just had to add, the irony, a sound card. (and it does not run Flatout 2 well at all. 2fps and it renders a black screen with HUD. Only when there is a crash you can see it's rendering the entire world. At least Quake 3 works great)
man, looking a restoration of some of the coolest piece of computing that i've ever seen and hearing general brainrot is not something i tought i would do today
Thanks for the video! As much as I'm into vintage hw and OSes, I know next to nothing about HP minicomputers (I know mostly about DEC & IBM). You got yourself a new subscriber; now where was that Apollo 9000/750 video? 😉
It's nicely preserved. I genuinley think if HP saw this they would want it in a museum. I bet they even still have the missing documentation archived somewhere to go with it.
Many of the later production 250s have a hard disk, the same one used in the abortive HP 300 "Amigo" workstation. The 250 shares a lot in common with the 300 even though they were designed by two separate teams, including its processor, display with softkeys and the console keyboard. The CPU is a hybrid module containing three chips produced using NMOS silicon-on-sapphire technology. It is based on the architecture of the HP 2100 minicomputer and was first introduced with the HP 9825 calculator. The design dates all the way back to 1973 and it was one of the first CPUs to be made in NMOS technology when most companies were still using PMOS. It can operate up to 10MHz, and later versions of the processor had an address extension unit giving it 32-bit memory addressing- that's up to a 4GB address space.
Back in the day, I used to program HP250/300/350 in Business BASIC - one of the best programming experiences ever until Visual Basic arrived on the scene.
at your age i would have keep the desk heater as a overgrown terminal for my servers. now much older i would swap the screen for a tablet and convert the keyboard to bluetooth/usb. either way great find!
Another really interesting HP machine, I like the design with the different boards. The CRT needs some restoration. The Discord conversation is a bit irritating btw...
I hope you understand how rare this is and that it was a only tiny chance you'd encounter it. Cherish it and don't mess too much with it, it might be very difficult to fix. Even though it's probably not super valuable in terms of money yet, it will be within a couple of decades.
I am extremely aware how rare this computer is. It is one if not the most valuable piece of hardware i have in my collection. even if it breaks once, i will do everything in my power to try to fix it. Since my youtube channel got a lot of traction in the last days, some people who originally worked on those machines reached out to me offering their help.
