I wrapped up my work on the Raspberry Pi version. It turned out very nice, and I devised a simple way to add a lighted power button to the front that I really like. It's just a clear keyboard switch with an LED attached, and a 3d printed button that allows the light to shine through...

I'd also add that you definitely should remove that battery. If it hasn't leaked yet, it might be good and dried out, but why take a chance to keep system time and your mouse speed settings! Every SE/30 I've worked on has had cap leakage under the caps. Most of them also had traces damaged...

I agree. I generally value my own labor at zero because it’s a hobby I enjoy. I buy caps in bulk to keep costs down. The $1000 for a nicely restored Q700 is not insane. I’ve generally sold within the community, trying to sell as close to cost as possible ( recapped analog and logic board...

For a more extreme example, here's one of Mr Goldman's sales: a Quadra 840AV for over $3k... Having to pay $700 multiple times to make people think that's a reasonable price would wipe out the profits from actually finally selling one for close to that.

I've got a side project where I am tracking sold prices on eBay and using it to provide an, albeit somewhat high estimate on going prices for vintage computers. And I've noticed there's some sellers on eBay that seem to have astronomically high sold prices on their eBay listings. These are...

Right now the plan was to just use a standard Pi. I've found the Pi 3b to be too sluggish for the LisaEm emulator, so I yanked a Pi4 out of an Arcade I built to see how it fares. I also have a Pi5, but it's so sensitive to powering it with anything but a dedicated, specific power supply, I...

Made some progress on the LisaEm emulator on Linux/ARM (Pi). I got it working now, although it is painfully slow on a Pi 3b. I'm going to borrow a Pi 4 from another project and see if it can perform acceptably. I'm trying to avoid the Pi5 because it is very picky with its power requirements and...

OK, making some progress at getting LisaEm running on a Pi. Seems like on Linux/ARM, chars are unsigned, which was causing the CPU to hang at 100% and cause the boot to fail and segfault. I've been able to successfully get the ROM to fully load and show an image on my Pi! Now I need to get...

OK, I have the case all set up for a Raspberry Pi and an iPad LCD. So yesterday I moved on to what I thought was the easy part, getting the emulators set up. Sadly, it seems the state of LisaEm on Raspbian is not good. As in, it doesn't work and it doesn't appear anyone is trying to get it to...

Honestly, I was able to get the image shifted very easily (and by I, I mean Claude was able to make the change easily) and even the on screen menu that comes up when long pressing the ESFloppy center button. The thing that took me quite a bit of wrestling was saving the location to persistent...

Got a pretty cool email this morning. Apparently this design on Thingiverse was put as the first featured design on the main Thingiverse landing page! Not bad for a design that probably has a possible audience of less than 50 people (not sure how many LisaFPGAs total have been sold, but It's a...

Yeah, I was pleasantly surprised with the quality. It was ~$50 USD from Aliexpress with a controller board (that I subsequently killed in my efforts to power it from a single 5v USB-C trigger board. So my setup also has a new generic $20 LCD controller added to it.

Released the current version on Github: https://github.com/wottle/lisa-mini for those who might be crazy enough to build their own.

I like it better with the logos. Gives it a bit more character. Might see if I can get the apple logo in color. Unfortunately my printer only does 4 colors. And I've already spent way too much money on this project!

OK, got a replacement LCD controller and this one seems much better. I did, however, change how I was powering everything . I now have it set up with a 12v DVC jack as input, split into two buck converters to drop the voltage to 5v. One to power the LisaFPGA and one to power the new LCD...

Started trying to chip away at the USB support, and have something to test, but for some reason I can no longer connect to the LisaFPGA over the USB-C port to push software changes to it. It sill powers up and seems to run fine from the port, but when connected with a USB-C data cable, neither...

I'm hoping to keep it cheaper and people can use a sufficiently rated 12v power supply. I think the 5v controller board that came with my 11.6" LCD is garbage, so I have an alternative controller board coming that is 12v. My plan is to splice the 12v input with one line directly going to the...

You could try grabbing my fork of Alex's repo and installing the version I have that allows you to run 1024x768. The image isn't quite as good as the 1080p output, letterboxed, because the scaling isn't perfect so I had to use dithering, but it would at least get you an image on the Eyoyo...
