If you want to be notified the moment that the LisaFPGA boards go on sale, fill out this form! Keep in mind that it'll probably still be a few weeks from now though. https://forms.gle/i4vdADcm5yNm8XUk7

The presentation I gave on this project at VCF is on YouTube now if anyone is interested in watching it!

Some bad news. JLC finished manufacturing the v3 boards on the 18th as expected, but it's been several days and they still haven't shipped. Normally they ship the day after manufacturing is done, but not this time, presumably because of the large size of the order. It's so late at this point...

Yep, that's absolutely right! The 75MHz number refers to the Lisa dot clock, not the CPU clock. The stock Lisa has a 20MHz dot clock and divides that by 4 to create a 5MHz CPU clock, so my 75MHz dot clock gives an 18.75MHz CPU clock, for a 3.75x speed increase. Sorry if I didn't make that clear...

Don't worry! Whatever happens (unless I were to die or something, but that's pretty unlikely), they will ABSOLUTELY be available for sale online. The only thing that's up in the air is whether or not they'll be here in time for VCF, but if not, then they'll just all go up for sale when I get...

I've heard a lot of good things about Joe from a lot of people, so I'm leaning pretty strongly towards going with him! I think I'll FINALLY find the time to respond to him today... Yeah, I saw that thread about the SE/30 Reloaded. Luckily, this is far from my first time dealing with JLCPCB and...

Good idea, I'll make an account on hacker news and start answering some questions. And wow Joe, you're actually the second person who's approached me about potentially being a reseller! I don't have a problem with that at all (in fact, that would be great), but there's just so much happening...

Wow, this is a lot of demand! Maybe the 100-board order that I was considering isn't so far-fetched after all...

Thank you!

Got it. As I mentioned, it'll all depend on demand, but I'll try to stay under your $150 figure if I can!

Yeah sorry, I probably should've put the questions closer to the end! I'm notorious for talking waaayyy too much in my posts sometimes... To answer @stepleton's question about the price, I really can't say yet because it depends greatly on how many I end up ordering, which of course depends on...

Over the past 8 months or so, I've been working on implementing a fully-functional Lisa inside an FPGA, and I'm happy to announce that I'm just about done with the project! I've designed a custom board that contains the FPGA and all of the Lisa connectors and interfaces that you need in order...

Thanks for all of the suggestions guys! If we're not able to find the original font from Apple's CAD package, I'll definitely look into the Fontographer thing. I hadn't considered recreating the font using the original text as a template, so thanks for giving me that idea if all else fails!

Hi guys! I asked this same question on LisaList2 yesterday, but I figured I'd post it here too in case anybody can help. I've been working on replicas of a bunch of Lisa PCBs lately and so far I've been able to get everything really accurate to the originals, with the exception of one thing...

All of the PSU voltages seem to be fine.
