Yeah, that's one of the things I had to give up by not having drivers on every pin. But it does mean this is faster (if it wasn't running on a 6502 or an Arduino Uno at least) and cheaper. Maybe bidirectional registers would solve it, but they'd also need over current protection ... some 74'XX's burn in half when they fail XD

Sounds cool about the pinball machines! I don't have any assembled units to sell you, but you skipped over why you want to skip the soldering? I'd like to hear more.

Also not great to open a drawer full of mercury dust when you get it in the mail.

Both software and hardware. $9.

​@@AndersNielsenAAGreat, thanks. If future versions could also support 1.8 to 3.3 volts, that would be great, as it would make the device suitable for programming serial EEPROMs and microcontrollers. This would significantly expand the range of potential applications.

Thanks for watching :)

Thank you! :)

Thank you!

Yes!

@@AndersNielsenAA great thanks.

In the video I also use a ZIF in a normal socket :)

@@AndersNielsenAA I'm going blind, so all I saw was a very fuzzy board drifting across the screen, over and over so I didn't finish it. I used to have a Fordham EP20? programmer on my bench, and we had numerous older progtammers fpr older chops like early PALs. I used them in a production and factory support situation. I also had to clear factor test data from the Dallas 3K=8 batterey backed RAM I loved it when the Capstore memory was devekoped, because tey were not only shipped blankm byut there was no battery to fail. It was two memory chis, a gapaciror and a comparitor. On powerup the EERoM was read into the Static RAM. On powerdown, it was written back to the EEROM Im sure your oard wil interest hobyists, but I quit watching wjen you said to put a better product in the closet. I worked in Broadcast and Telemetry equipmen manufacturing. Programming had to be performed on name brand equipment, and maintained in our Merology lab. I even used the so called programmers for cable TV boxes and security dialers that pulsed a DIP resistor pack to open sselected resistors. I have over 100 pieces of lab grade test equipment in my home shop, after retirement. I won't say anything bad about your design, because I couldn't make out any details.

The main cost cutting measure for the programmer is *mostly* relying on the JEDEC standard layout. That means it can supply some of the voltages needed but you’d need an adapter or jumper signals to a breadboard. And write a programming profile.. Aren’t the 82S’s all (otp) PROMs? Do you have a bag of those? I’d love to get my hands on some :) Firestarter has a database with all supposedly supported ROMs - not all tested for obvious reasons :)

Thanks 😊

I’ve released a video on doing half of it - it’s possible to add the transistors to the configuration jumpers as well

It’s on the literal first page after you tell you’re from the only country in the world requiring companies from other countries to register for VAT. You can probably find older revisions on eBay.co.uk - I’m unsure if “Tim’s Retro” is going to order a batch of Rev2s as well.

Maybe there’s a way - I’ll take a look

It’s a bit out of scope. It would take an active adapter board with an additional address latch.

@@AndersNielsenAA Or its possible to program 40pins with an adapter where you can set the high addresses manually and program in chunks.

Funny you should point out software - because that’s where the TL866 is the worst. It’s got a binary blob firmware that can’t be modified and relies on reverse engineering to get minipro running. This programmer with the firestarter firmware on the other hand is as easy to use as minipro and even programs a w27c512 faster with slower hardware :) I guess you just haven’t checked out Firestarter 🔥

​@@AndersNielsenAAand it's open source :)

I claim it has a PROPPER software, at least 600+ PROMs are currently supported. The collective effort of the Open Source community is adding more PROMs and features all the time.

A python script is not software. Command line is not software. GUI with libraries is proper software.

@@fadate7292 In that case the TL866II has no software for Linux, MacOS, Android, and all Unix's :) Firestarter will run on your phone.

You’ll want to go with the Firestarter firmware - you can check out my video “Open $9 ROM Burner just got even better and easier to use!” .. it’s basically two commands :) Or just come around the clubhouse and ask anything! :)

Here a group of university students were hospitalized after close contact with a sterilizer. Mild symptoms. I’m not speaking from experience but I’ve heard you can get permanent eye damage because it doesn’t hurt to stare at it for too long - so you definitely want it covered up in case a child finds it in 20 years. Happy to hear it’s hard to do accidentally if you already know not to stare at it :)

Yes - but it takes a cut and a bodge wire :) They’re more rare so I haven’t had a chance to try myself :)

I’m happy you like it

And New, and Favorite, and Here :) I assume you're referring to the title capitalization?

@ oh it was a much worse, indirect and niche joke because I’m not funny. Good video!

@@Warlock_UK Thank you. I'll learn to get jokes eventually :)

I don't think people will be building or buying this if they already have a T58 - and you're first to mention a need for more plastic. Nobody wants to cover up the blinky lights :) There are quite a few Arduino Uno cases that would work for the bottom half though. And I guess I could design a 3D printable case for it - but nobody's suggested it.

You are a consumer unlike us... You want shiny boxes, we do not care and a project just has to work. Tinkering is so much fun imho...

@@sjococoa case is part of a system that prevents you from destroying it with ESD and makes it more convenient to use. It’s not the only part of ESD design, but it’s a piece of it!

probably brexit is a cause

Yeah, it's a Brexit thing. HMRC requires all companies selling in the UK to sign up for UK VAT (at no minimum quantity), and that liability is a bit much for a small thing like mine. I also got a few very contradictory letters from them - and both kinda saying I *must* sign up for UK VAT but at the same time my revenue is too small to do so. Fun times. You will however find the Relatively Universal ROM Programmer Rev 0 on ebay.co.uk - Tim of Tim's Retro is still selling them afaik. Don't know if he'll order a batch of Rev 2's for UK customers as well. Other than that there's direct from JLC with the coupons n such.

@@AndersNielsenAA Thanks Anders, I will follow up on those options.

Straight from ROM to Core Memory :D

Thank you! :)

Exactly!

Thank you for the amazing work! Wouldn't be half as useful without it - so keep it up too! :D

Could use a better acronym but I'm not sure that one will be appropriate :)

"FUCKUP"! I love it!!

Maybe not that gathering specifically :)

Huh?

@@AndersNielsenAA you only talk about it. you did not actually do it. i click on this new video from a creator that I didn't know about. I thought I was going to see this done, and in action just by the title. i feel that I was mislead, that's why I commented the way I did. i did learn something new though. I didn't know motherboard manufacturers at that time did that to floppy controllers. I am intrigue by the disk image program that talks directly to the drive though. that could be a good video.

@@AndersNielsenAA reading the other comments. it does seem like you do some low level things though, which is cool. i didn't know you can use other controllers as gpio pins, I do wander a little bit on how you do that though...

Thanks for the feedback - I do try not to bait. This time I had to spend a little bit too long on the “why” before getting to the discussion on “how”. The good news is I got a bunch of good feedback and I think I’ll demo several ways of bit twiddling when I get back to this - and not just the usual “throw a Pico at it” :)

Exactly! But I do consider using a USB GPIO thing (even an FTDI dongle would do) or the parallel port cheating - I’d really like to explore the cheap and hacky solutions :)

👍

Better see how fast I can whip up an FDC then :D

GitHub link in the description :)

Thanks for the vote! 8-)

Thanks for watching!

Have a look at my newer videos or google the 65uino - it's just a PCB version of the same project. The project page on hackaday.io is a good place to start :)

Thanks - it was fun! :)

Also have to admit I still have a key with issues - one of the spring holders broke in half so I’ll have to take it apart another time too. Super fragile.

Rev 0 and 1 - all boards out there so far.
