Address decoding & some simple sequential logic

Yes you need the proper Atmel one which was hard to find and not cheap at around £100 IIRC.

Grr. Come the revolution, custom programmer designers will be first up against the wall.

Yep.. Atmel would be a lot better if they would release the programming sequences and whatnot.. Currently I don't think there are any clones because of it

I would have thought if they were easier to program more people would buy them, but maybe Atmel just want to sell lots of programmers who knows....

I'm a fan of the ATF150x series, it's a shame they recently discontinued the PLCC variant but QFP's are still made.

I have no idea how well it works but there is this open source Little ATF Programmer:
https://github.com/roscopeco/ATF150x-Programming-Board
https://github.com/roscopeco/atfprog-tools
https://store.rosco-m68k.com/products/l ... programmer

I bought one from his store but haven't had a chance to test it yet.
It was mostly as a show of support since I've already got the ATDH1150USB programmer.

Thanks all.

I thought I'd give this WinCUPL a try as both the 16V8 and 1500 series seem to use it so I started installing an XP virtual machine yesterday.

Even that's a pain! It's been stuck on 39 minutes remaining for about 20 hours

I've got WinCUPL just running natively under Windows 10 x64 no problem. You must have found an absolutely ancient version that it needs XP.

Oh!

Microchip dev tools front page says Win XP on it (https://www.microchip.com/en-us/develop ... ol/wincupl) and I saw a demo that showed there were missing features when trying to run on later versions.

I was going to have to build a VM for it anyway, so figured as XP was probably the ideal VM candidate anyway I'd go with it.

Turns out there's some incompatiblity between Virtualbox, the XP I have and the machine I was trying to run it on, though.

I run it in win7. Not sure anything was missing

I'm also running it under Windows 10 x64. v5.30.4

I’ve been running WinCUPL on my Mac in a Windows VM for years, it works with Windows 10 or 12.
Keep in mind, if you run into issues it’s not because of the underlying OS, it’s just because the software is totally crap, full of bugs and very strange behaviours. With patience you usually end up with a proper file to program your PLD….

One of the biggest problems with WinCUPL is you have to be careful not to copy paste code from the Internet because it often contains hidden characters which will crash WinCUPL without any sort of obvious reason... Aside from the occasional general crash, I cannot say I have ever really had any problems with it..
