Prototype board based on EPM7064S (same as ATF1504) get lots of use; many designs can easily solved with 64-macrocell CPLD. I'm on my 4th batch of ProtoRC3 (10 boards per batch).

Fingers crossed that my ATF1508 Dev Board is going to work OK (Rev 1 works with some snafus). If it does, I'm probably going to be done with that design unless I decide to go with the TQFP-100 version. Anyway, I can see the need of creating a 1504 version specifically for glue type logic. Something that could be mounted on a breadboard. However, I could always use my 1508 version and just keep the designs small (or use one of the PLCC-44 to DIP44 adapters) on a breadboard. What are your thoughts? Any interest in something like that or do you guys use them in a different way? Thanks |

I personally created a couple ATF1508 dev boards that actually worked. The first one had a stupid mistake where I got the JTAG header backwards...lol. But it still worked when I added it to the back of the board. The second one worked as well. However, I put my CPLD activities on-hold because I was tired of using Windows in a virtual machine just so I could use WinCUPL. I found a P4 laptop for $10 or so a while back so I might load it up just for WinCUPL. But I have a confession....I'm contemplating using a Raspberry Pi Pico for some glue logic. Mainly because I have some. |

For breadboard use, I recently ordered one from the gerbers provided by user banedon here viewtopic.php?f=10&t=5055 |

I've been holding off using a micro-controller on my build because I just don't feel they fit the "spirit" of the retro designs I like. But I'm starting to get over that obsession. I'm interested in playing around with the PIO's of the Pico for various things. And at $4 each, it's hard to beat. The downsides being 3.3V and only 26 GPIO. But that's not the end of the world for me. |
