Skill, ingenuity, persistence, eloquence. And you must have some cash to afford these cool toys. The perfect tech KZbinr?

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!

Well done! Must have been satisfying to type in the test code using that keyboard.

Beyond satisfying! I've been held back from seriously using this computer because of it's faulty keys. I have quite a few plans for it so now I get to put them into action!

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!
@TechTangents
@TechTangents 6 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?
@TechTangents
@TechTangents 6 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.

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?
@TechTangents
@TechTangents 6 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.

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.

Yup, retrobrite. He also has guides for them on kzbin.info/www/bejne/jIaap4uDmt-Klas and kzbin.info/www/bejne/p4u8k5aeq7iIers

Ave O Yes, thats it! It would return the computer close to its original appearance. I plan on doing that in my old olivetti. I think it could even potentially make a interesting video subject for Akbkuku.
@TechTangents
@TechTangents 6 жыл бұрын
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.

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.
@TechTangents
@TechTangents 6 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.

Hey, I have an HP85, which has a built in monitor, tape drive, and printer. Whenever I run a basic program, the results are printed out by the printer instead of being displayed on the screen. Any idea on how to switch this?

KarjamP Blind? Not at all. Humans tend to watch and remember more letters and word than numbers. Thats why we use dns, instead directly ip. Also i dont really watch the numbers, and o think that one was out of his standard, i think he in the past added 1 to the episode number, and then put in the title "part 2" or something like that.

It is one number off, so they are all too similar. I'm not sure how you read, but I skim over the title before watching, so people like me will think they are the same title

Are you still going to make a follow up video on the computer itself? I cut my sysadmin teeth on an HP 9000/I70 (Love PA-RISC). Ever since I have been fascinated with old HP. They are definitely not the same company anymore.

All this work with the switches and numpad keycaps are still covered in doritos dew spots. Not wanting to damage it with retrobright is fine, but come on, soap bath could not possibly do any damage to them.

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?
@TechTangents
@TechTangents 6 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.

The contacts for the keys are permanently put in the black plastic and then soldered to the PCB. You an only unlatch the original key stems from the back.
