A MILLION thanks to everyone who supported me by becoming a channel member or buying kits and IC's from my webshop. Thank you! Relatively Universal ROM Programmer kits now available: www.imania.dk/samlesaet-hobbyelektronik-og-ic-er.htm UPDATE: I've been completely overwhelmed with the orders for the Relatively Universal ROM Programmer, so I've turned on "Order without stock" on the shop. First come, first served for the next batch. That effectively means pre-order for the next batch - which won't be long with the amount of support, wow. Thank you all SO MUCH for the support - it's been amazing! Stay tuned for software updates!

Great work! I love open source projects as its beneficial to the electronics development. I was just wondering if there was any reason to not include a built-in TTL to USB adapter right on the PCB

@AndersNielsenAA Ай бұрын

Good question. It's because the UART really belongs on the host board, in this case the 65uino, but the 65uino doesn't have one. All other boards I imagine that can be used for the shield should already have a UART on those pins - so that's why I only put the pins for external UART. An Arduino or STM Dev. board should be able to use the internal UART just fine, without the extra wiring :) 65uino itself will probably get a shiny new UART->USB on the next revision.

I can think of some ROMs it won't program (1702A, 2704, and other super early eproms that require multiple voltage rails and/or silly high voltages). But really impressive. The lack of ability to program 25v+ eproms in the TL866 has always been a bit of an annoyance with it. I know there's already voltage adapters out there but nice to see a completely open source solution for programming ROMs that can be done very cheaply.

@AndersNielsenAA Ай бұрын

I thought of going all the way with the +-5V boards, but instead I just decided to break out all the control lines and driver outputs. That means you can either bend up a leg of a socket with the 2704 in it and connect -5 to that, or just run the needed lines from the pin header or the socket itself. Not as plug and play, but it will work :D

This is a really cool project, great job on bringing this board up! I've seen a lot of similar programmers to this based on older designs that go for a lot on ebay. One question, would this be able to program a NOR flash chip? I have a need to program, and plans to design an adapter as it's an SMD part, so I was wondering if that's a type of ROM chip that you would expect to be compatible with this programmer. I'm a little new to programming them, but it seems like the procedure for programming is fairly standardized across parts. Thanks for sharing this design!

@AndersNielsenAA Ай бұрын

Thanks :) An 8748 not only requires 21V programming supply, it also requires an 18V pulse at the same time, and the pins in no way line up with a standard JEDEC ROM pinout, so that'll have to be a no for the 8748. I guess technically you could use two of these.. But that gets complicated fast :)

@borayurt66 Ай бұрын

Great project! Since it has the same pinout, could this be ported to an Arduino UNO too?

Thank you! For many the T48 is the better option. Link in the description. I could’ve also included a CH32V203 or something to make it standalone but the real value in the more “commercial” programmers are in the software.

How does it cope with voltages on other pins, eg some eproms need 6v on pin28 whilst programming

@AndersNielsenAA Ай бұрын

It doesn’t raise or lower VCC during programming or verification - as far as I know it’s rarely strictly necessary for a programming to stick. And if you need more reliability for those specific ROMs I believe a double programming might just accomplish that. But hard to know anything for sure with 30 year old EPROMs

Congrats! Really nice project. I do think the name is a bit problematic though. This is obviously a ROM burner for really old types of roms and not current day EEPROMS that often use voltages such as 3.3 or 1.8 V and can be very large. I'd suggest you add the word "retro" to the name so people don't waste time (and possibly money) on the wrong device.

@AndersNielsenAA Ай бұрын

Thank you and thanks for the feedback! The "relatively" in the name hopefully conveys part of that :) The thing about the really modern EEPROMs is they don't require high voltages and the packages typically mean they need an adapter anyway - so it's a simple matter to do that on a breadboard (or a much simpler PCB) instead. Basically you can make a shield for a Nucleo board that does it all for $1 a board. This board should technically work with 3v3 if you power it with 3v3 instead of 5V - though I think it's hard to find anything in DIP that can't handle 5V.

@BrainSlugs83 Ай бұрын

Would be better if it could handle up to 48-pin PROMs, that's where the cost starts to get really prohibitive.

XD I actually also very literally made a thing. "Literal" means exactly what it says without metaphor or exaggeration. For instance, if you say "It's raining cats and dogs," that's not literal because it's a figure of speech. But if you say "There are three apples on the table," that's literal because it directly states a fact. So, "literally" is used to emphasize that something is true in a strict, factual sense, without exaggeration or metaphorical interpretation. -ChatGPT XD

You can turn the board into the socket by offsetting every other pin by slightly less then half the diameter of the hole. So for pin 1 move the hole about half the diameter of the hole in toward the middle of the chip and for pin 2 move the hole about half the diameter of the hold away from the middle of the chip. Do this zip zap pattern for all of the pins. This will hold the chip in place for programming.
