doragasuPeople doing <a href="https://mastodon.sdf.org/tags/Electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Electronics</a> here, I am still searching for a substitute for the LCMXO256C <a href="https://mastodon.sdf.org/tags/CPLD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CPLD</a>. Up to 2019, you could buy these below 2€ a piece on Digikey. They have 256 cells and 78 IO pins, making them quite interesting for that price range. During the pandemic their price raised wildly and now they are 10€ a piece, so I have been searching for a cheaper alternative without success. Any recommendations?

Dirk WoutersDas EasyGate1541 jetzt auch für die 1541-II Das EasyGate1541 war bisher nur für die “alte” 1541 erhältlich. Die spätere 1541-II bekam von Commodore ein anderes Gate-Array, das noch mehr Funktionalitäten integriert hat. Es war an der Zeit, dass eine Alternative geschaffen wurde.<a href="https://mastodon.social/tags/1541II" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#1541II</a> #1571 <a href="https://mastodon.social/tags/Array" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Array</a> <a href="https://mastodon.social/tags/commodore" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#commodore</a> <a href="https://mastodon.social/tags/CPLD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CPLD</a> <a href="https://mastodon.social/tags/EasyGate1541" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EasyGate1541</a> <a href="https://mastodon.social/tags/EasyGate1541II" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#EasyGate1541II</a> <a href="https://mastodon.social/tags/Ersatz" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Ersatz</a> <a href="https://mastodon.social/tags/Festplatte" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Festplatte</a> <a href="https://mastodon.social/tags/Gate" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Gate</a> <a href="https://mastodon.social/tags/Laufwerk" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Laufwerk</a> <a href="https://mastodon.social/tags/Xilinx" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Xilinx</a><a href="https://dirkwouters.de/easygate1541-ii/" rel="nofollow noopener noreferrer" translate="no" target="_blank">https://dirkwouters.de/easygate1541-ii/</a>

Phil M0OFXWow, the Xilinx/AMD CPLD discontinuation is an absolute bloodbath. Does that leave us with the Microchip ATF1500 series being the only 5V-tolerant FPGA/CPLD on the market? That's not great for retrocomputing, I've found the tools for that chip to be pretty awful (WinCUPL, seemingly no higher-level HDL support).<a href="https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/5783/XCN23009.pdf" rel="nofollow noopener noreferrer" target="_blank">https://mm.digikey.com/Volume0/opasdata/d220001/medias/docus/5783/XCN23009.pdf</a><a href="https://digipres.club/tags/Electronics" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Electronics</a> <a href="https://digipres.club/tags/Retrocomputing" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#Retrocomputing</a> <a href="https://digipres.club/tags/FPGA" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#FPGA</a> <a href="https://digipres.club/tags/CPLD" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#CPLD</a>

Brian SwetlandLooking at the ATF15xx 5v CPLDs and was going to just have some of <a href="https://mastodon.social/@whitequark" class="u-url mention" rel="nofollow noopener noreferrer" target="_blank">@whitequark</a> 's EVBs fabbed, but nobody has TQFP parts in stock right now.The magic of open hardware meant that I could just grab the design files, fire up KiCAD, throw together a footprint, adjust the symbol for the PLCC variant, and widen and reroute the board to make room for the larger footprint. Having a nice, clean original design to work from was an enormous time saver. Yay.<a href="https://github.com/whitequark/ATF15xx-EVB" rel="nofollow noopener noreferrer" target="_blank">https://github.com/whitequark/ATF15xx-EVB</a><a href="https://chaos.social/tags/projects" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#projects</a> <a href="https://chaos.social/tags/cpld" class="mention hashtag" rel="nofollow noopener noreferrer" target="_blank">#cpld</a>
