On another note, does anyone have any plans on a case or backing board for this device? I haven't really given it much thought.

I've designed a 3D printable case based on the board's 3D model, but I haven't yet had the opportunity to test it with a real board. I'm tracking my board's delivery and expect it tomorrow. Once I have a chance to test fit and make any necessary adjustments, I'll share my case design with others.

Below are some photos of the prototype case.

Quote from: slewis1962 on Yesterday at 10:52:59 PMIt works! I tried with my DVI monitor with HDMI to DVI but it wouldn't work. I hooked it up to my boys HDMI gaming monitor long enough to verify functionality and it functions perfectly! Alex, this is the greatest piece of electronics gear since I purchased my Lisa 1 in 2002. This is awesome! I booted LOS 2.0 then MacWorks. Can't try my Twiggy drives as they somehow left out my Twiggy adapter board. I've already contacted them and hopefully will hear back next week.

I'm so glad it's working for you! Sorry about the Twiggy adapter board; it looks like they accidentally oversold by one and you're the person who bought the extra one that didn't exist. Mark will give you a refund, but Joe still has 3 in stock if you want to grab one from him: https://jcm-1.com/product/twiggy-breakout-for-lisafpga/

In addition to @coffemuse's case, some people on TinkerDifferent appear to be working on one too. I'm not great at CAD modeling, so I'm not even bothering to try myself and I'm leaving it up to the pros.

I may just wait on the adapter board until others have tested it out.
I ordered an HDMI monitor from Amazon which will be here Tuesday so I don't have to steal my boys gaming monitor. I'm looking forward to getting more time with the FPGA Lisa.

I'm not a CAD professional either, but I have enough knowledge to create boxes with holes and rounded corners (and some additional embellishments). However, after reviewing some of the design concepts they showcased on ThinkDifferent, I would consider my design to be quite "novice-level."

Hopefully he won't mind being without the gaming display until Tuesday. Lisa takes priory, right?

Exactly! Well done on the case design!

I was thinking with this new way of using the Lisa I might try programming. I've wanted to do something for years and never got around to it as I always thought my 40 year old computer was too fragile for extensive use. I used to write programs in Pascal on the Macintosh as a hobby and have programmed the 68000 in assembler so Lisa Pascal shouldn't be too hard. I just need to figure out something worth programming.
