Do have a look at Mikes program you won't be disappointed. It's called PL2260. Congrats for doing your own though, way above my understanding.

Cheers for that. I did see a French based site with some windows stuff for the IO22 but it seemed a bit out of date so i decided to have a crack myself(i did not come across the site you mentioned that would have saved me some time). TBH i actually enjoyed the challenge of coding my own(which i have not yet completed but the loading, saving and transferring of files part of the program works which is all i need for now and will finish the rest when time allows) A quick screenshot of the 2 versions i was working on(1. Simple and 2 more in-depth). Both where in the very early stage of development and will probably look far different when complete. 1. 2.

Hello All As a new memeber here Is this the place i say Hi, As cant find any Introductions Forum page Any way if so Hello to you all

Superb ron love the rugs

I assume this is the Data I/O 22? If so did you know a guy called Mike DiBattista has written a Windows program to talk to all the Data I/O programmers and very good it is too. I use it all the time with my 29B. It's a free download from the groups.io forum DataioEPROM but you'll need to sign up first. Hope that's useful.

Oh, Happy Memories of 50 years ago😁

Funny you should mention that! I used to have this one.

Very interesting items. In the right environment, they will look great.

Love that! Very nice to hear about the comprehensive documentation and in exactly the right hands. I got lucky with second hand modern kit that can handle oldskool jobs like 2708

Cool. I have often looked at buying one, but it seems like a quantum leap, since I have no clue about them

The manual is quite large but very informative they even include the schematics. The only minus s lack of modern software available so I had to code my own so I can transfer files to and from the programmer(the protocols are also included the manual).

Ooh nice. I hope it has instructions...

I just go for a full old school programmer for an old scroll job(I also use this for programming mars mechs).

My god i remember my parents having one of these at home in the 70s but it was purely electro-mechanical, bloody 48v relays and cam switches galore, I remember the noises it made and loved that 70s pub smell you got every time you opened the back door.🤣 (Edit, just remembered it was actually called Housey Housey).

Fine as they are just going to be used in front of machines in my man cave.

😅😅 very nice Ron, how has that gone down with the Mrs?

I had thought about building one of those. Never got round to it though...

Didn't realise there were 4 supply voltages needed. Not many pins left on the chip with that lot connected 😆 I'd think twice before putting a rom in something I'd knocked up... Especially if it was the last one known & no backups existing... Then there is the software side and multiple manufacturers of 2708 Looks like 2708 have got expensive to come by

Wow. That's a lot of £s for an adaptor. I did build an Arduino shield version, which initially read eproms ok, but when I tried to burn some, they literally burned 😳. I'm guessing that I got something wrong.... An easy to build programmer for 2704 / 2708 / TMS2716 / MCM68764 / MCM68766 EPROMs – Matt's Tech Pages https://share.google/y1qxj95mkDGOs1Bk1

No worries. 2708 are an oddball to burn & most modern programmers won't do them... And the ones that do need an extra board. Bloomin hec that's doubled in price https://uk.dataman.com/products/module-2708?srsltid=AfmBOooYeXc0uQvN1mGMw2gPi9a6AWTNEYT25lHaGEIACYTqJlNvPFXW Plus need the programmer like a Dataman Pro40 to plug it in to too... Sure @superbankknows what he's doing & got the kit though 👍

Thanks Louie. Many thanks for the offer. Very much appreciated 🙂 Superbank has kindly offered to do this for me. If he has any problems, I would love to take up your kind offer... Cheers, Pete

ROMs are about as it's emulated https://www.desertislandfruits.com/forum/index.php?/files/file/1246-nudge-double-up/ that's the had bit covered I've got the right kit to burn SRU roms and perhaps have some good spare 2708 too. Looks like I ripped a set 😁 https://www.fruitemu.co.uk/ib/topic/19629-sru-unknown-rom-set/#comment-305933

Working !! The new board arrived and when I took the old board out I realised one of the new chips was only connected one side !!! Put them in correctly and all working and know sec fault too !

Hi , ive just done what you said but its still not made any difference
