Not so much cash as patience. I only paid $100 for my entire setup for the HP86 and that is about the bottom rung of 3D Printers. I'm very calculated at when I buy things and like to wait for a great deal.

I have an old Lear Siegler ADM-3A terminal, which has the same type of Hi-Tek switches as the HP86 and TI99. It's got the sticking keys problem pretty bad as well, especially with the keys near the edges. These replacement key stems will definitely come in handy when restoring it! It's always awesome to be able to fix vintage electronics with modern technologies like 3D printing. Thanks for making another awesome video!

This has been a tremendous effort! - wow! - Your Key Stem design might also work on the Oric Atmos computer keyboards. They are Stackpole keyboards as well!
@TechTangents6 жыл бұрын
It most likely would if they are the same switch type. These should work with some of the DEC terminal keyboards as well. I may make more of a tutorial type video of installing these in one of my TI99s. I don't think either of them have any bad stems, but I'd like to make it as easy as possible for people to do this themselves.

Is that programming language a highly customized version of BASIC, or is it something else?
@TechTangents6 жыл бұрын
It's HP BASIC. Unlike a lot of the other computers at this time, it is not derived from Microsoft BASIC. It was developed from the ground up by HP. Since it is wholly owned by HP they continued to support it up until at least 2000. I have an HP programmable Multimeter released then who's manual contains programming examples in HP BASIC.
@vwestlife6 жыл бұрын
In the same vein, Texas Instruments calls the language used by their graphing calculators "TI-BASIC" even though it has almost no keywords or syntax in common with standard BASIC.

VWestlife it's the same with the Casio fx-cg20. It has a language on it that is called Casio-basic and when I got mine I thought that it was real basic. I was really disappointed when I noticed that my commands all resulted in Syntax errors

3D printing is pretty awesome! One question though: At 8:38 it seems you did not solder one pin. Is that from that special stem on the End Line key?
@TechTangents6 жыл бұрын
Yes, that isn't a real key position on my keyboard. It probably is a real key though in other regions with different layouts.
@LoLSmileyFACE6506 жыл бұрын
What was that last original key you left on there for? With the two top... stems? I’ve never seen a design like that before. Awesome restoration btw. Good thinking to allow those keys to be pulled back out like that

It's an alignment post for the End Line key since it's too long for just one stem

You could try to make the computer case and keys less yellowish, kinda "reverting" its age, if you want. I've seen 8bit guy doing that, i think he call it retrobrite, or something like that.

I had this in the description of the first video: Yes I know the case has yellowed like crazy, no I will not be retrobriting it anytime soon. The only thing I've attempted that on did not turn out well and I will not use this computer a guinea pig for that.

That's no problem. Retrobriting is something I plan on covering here eventually. Those 8bit guy videos gave me some ideas and I've got some equipment that I'm going to try and make a 100% reusable retrobriting station with. No consumable resources.
@GoldenTrumpet246 жыл бұрын
There's a idea that I wanted to do for a while but don't have a 3d printer to make it. I wanted to make a bar top arcade cabinet for the nintendo switch. Using a magnifying sheet to make the screen look larger and design a fight stick that sits on top of the joycons. And maybe create a door in the back to hold the cartridges.
@TechTangents6 жыл бұрын
I think that would be better done as a hacked dock. Use a 20" computer monitor as an HDMI display and usb joysticks that you are free to cut up and modify. Using a magnifier will have two negative effects. The brightness will be considerably reduced because the same light is stretched over a larger area. And the viewing angle will be very small to be able to see the whole display.

I'll probablly have to sell my soul to get one of these, but how much will it be to get some pre-printed key stems?
@TechTangents6 жыл бұрын
I haven't gone into the numbers too much and I still need to setup the tindie page(I've got a long-term project going right now and I haven't had my 3D printer setup in a while). After June everything should be back to normal and I'll get that finished up. As a rough estimate, I'm thinking $0.50 a key stem with a minimum of 10 + three of the install tools. Possibly some better discounts for larger quantities but I need to keep in mind that the printer take about 14hrs to print 100 of them so it is locked down for a long time.
