LisaList2

Nice work!

Just pushed some changes to LisaEm that fix some outstanding UX bugs that have eluded me for years now. Putting Claude Max to work in my downtime.

Changes include:

- Better Profile/dc42 disk image handling in Preferences
- Switching Prefs to a modal
- streamlined preferences design
- fixed some OnQuit errors
- properly unmount disk image when selecting new profile disk image in prefs
- disallowing the same disk image file on multiple parallel ports
- Updated wxWidgets to 3.2.11 on macOS

More changes to come. These are in the master branch, currently, and require a local compile. Feedback welcomed!

Quoteunable to get a rectangular pixel PROM

There are various EPROM - PROM adapter designs that I suspect will work fine for this purpose, but I do not have experience with any... has anyone tried one?

As far as I know, John Woodall has very recently formally retired, and the business is in the process of being transferred to another Lisa enthusiast.

I don't know the timeframe or specific nature/extent of the resumption of operations, but I believe it will happen.

In the interim, I may be able to help out by suppling a small quantity of a very short list of Lisa specific items (eg. ROMs, PROMs, PFGs) to addresses in Canada... shipping to USA is currently an awkward, complicated and frequently changing complication. Inquiries should be sent via DM here or email: I can't supply any circuit boards, power supplies, floppy drives, etc., and may easily be overwhelmed by requests, so keep your expectations low.

This may be well-known but it is news to me if true. Someone on 68KMLA reports being unable to get a rectangular pixel PROM from them owing to them having "ended business".

The VintageMicros website appears to be operating as normal.

LisaFPGA Case — a 3D-printable "pizza box" for your LisaFPGA (Rev 3)

Hey everyone,

Some of you have followed my case progress over in the main LisaFPGA thread — thanks for the interest! I'm giving it its own thread here so the case chatter doesn't crowd out the board discussion.

Quick recap if you're just seeing this: my LisaFPGA had been sitting on the bench without a case since there wasn't one at launch, so I fired up Fusion and made a simple one. It's finished now, and the files are up for anyone who wants to print one.

It's a basic slab / "pizza box" style enclosure:

• Cutouts for all the ports, except the 4-pin twiggy header. **
• Lift-off lid for quick access to the switches, jumpers, and LEDs
• Vents over the FPGA for cooling, plus a grille over the speaker
• Four M3 bosses that line up with the board's mounting holes

** I have no Twiggy drives and I needed the extra plastic for strength of the case on right side, so I decided to omit the opening for header.

I printed and verified mine on a Bambu Lab X1 Carbon in PETG HF (Beige) on a smooth PEI plate. The repo has a ready-to-slice .3mf laid out for the X1C, plus separate tray and lid STLs if you're on another printer. Supports are required (already enabled in the .3mf).

Released under CC BY 4.0 — remix away. I'm no CAD wizard, so suggestions and improvements are very welcome.

And a big thanks to Alex (alexthecat123) for the LisaFPGA itself.

Below are photos of the case in use. The lid appears slightly unusual in the photo. I ran out of the beige filament halfway through printing the current design, which is why half of the lid is white. I had already used two other rolls of beige filament in an attempt to achieve the correct fit for the PCB. I plan to print another case in a solid color once I order more filament.

yes please

My case design has been updated and now fits the board perfectly. However, my printing experience took a turn for the worse. I ran out of the beige filament halfway through printing the new, resized lid, which is why half of the lid is white. I still need to polish the design a bit, but I'll publish it this weekend for anyone interested in printing their own case.

I am able to run my Lisa 1 with LOS 1.0 WITHOUT the twiggy drives attached, but the LisaFPGA hangs with the hourglass once LOS 1.0 loads.

It's hanging after the desktop icons appear and before the window menus are drawn, correct? If so, that is the same experience I have. It's trying to reset and mount the Twiggies and hanging because they're not attached.

The BMOW FEMU cannot emulate Twiggy drives. There was a proposed project with Steve Chamberlain a couple years ago to add Twiggy emulation to the FEMU. It could be done, but there was very little interest and the time and cost required was not considered justifiable.

Perhaps Alex can include Twiggy emulation in the ESFloppy?
