If you want, I can text Adrian and see if he can send me the profile!

Quote from: ried on January 19, 2026, 10:48:37 PMInteresting. Those settings should be universal for all Lisas that don't have the screen mod installed. Can you describe the hardware you're using and how it's failing?

Lisa 2/10 no screen modifications H rom.

The only way I was ever able to get it to work was to use a connection directly to the chip. A few weeks later, the chip went bad on me so I abandoned using that method. I couldn't get a nice clean way to get the video out of the back anyway.

I've seen several others state that they couldn't get their 2/10 to work with the RGB to HDMI either.

Sadly, I tried those quite a while back and they did not work either.

QuoteCan you give me any guidance or even some pictures on how to connect the cabling? I'm nervous about frying it since I read the cable is not keyed...

You are wise to be cautious as one sometimes runs across strangely incorrect combinations, eg. Lisa 1 internal chassis cabling with a 2/10 motherboard (which means the 26 pin internal connectors are mismatched and connecting to them can result in damage).

If you have a 2/10 motherboard (so no back panel parallel port, ignoring expansion cards), then in the drive cage area there should be one 26 pin cable and one 20 pin cable.

If you have two 26 pin cables in the drive cage area, then you should have a Lisa 1 aka 2/5 motherboard with 3 DB25 connectors along the bottom (two serial ports, one parallel).

QuoteI did manage to get Lisa OS installed via my Floppy Emu. Interestingly, when I go to Preferences > Connect Devices > Expansion Slot 2 > 2 Port Card > Lower Connector, it already has "ProFile" listed for that Parallel port. It's almost as though the Lisa can 'see' the device but can't mount it (if that terminology fits here)...

If it appears in the "Startup From" menu, then Lisa recognizes it is there... the CPU ROM actively looks for expansion cards and if it finds one, it gets the icon for it from the card's own ROM.

The Preferences in LOS are not so smart: the default installation always shows a 2 port card in slot 2, but this is because it was pre-configured to expect that, not because it looked and found it... ie. it pre-dates "plug-and-play".

The correct settings are available in this thread: https://lisalist2.com/index.php/topic,454.0.html

The Lisa profile that comes with RGBtoHDMI was made by the creator using lisa specs not with an actual lisa.

It doesn't work with my Lisa as well as many people's including when Adrian tried it on his show.

He got a new better profile and said it would be included and updates to the video adapter, but I haven't seen any updates posted.

I think Alex's suggestion to use the internal Widget connector is your next logical choice. You'll find the correct cable connections shown in this post: https://lisalist2.com/index.php/topic,556.msg3998.html#msg3998

Your SD card uses Master Boot Record and is formatted MS-DOS (FAT32), correct?

Hi again. Yep, just double-checked: the main SD card I've been trying to use is indeed FAT32 formatted using MBR.
