Level shifting wasn't needed before because I fully implemented the VGA functionality on the V4 M4800 (as in it already outputs 5V HSYNC/VSYNC, and has 5V DDC support). Again, this was only for bring-up purposes, so I didn't care if it's not MXM compliant, since it wasn't supposed to be used 😀

On the regular M4800 I sent you, it doesn't care for HDMI HPD and EDID, as all that stuff is on the board. On the Llama edition, I routed those to the MXM connector.

Got it! I'll make the changes and reach out to you when I'm done, so we can compare schematics? 😀

Sure thing!

@Eivind I am both excited and curios about this project. Would you please care to share current status?

Cheers.

Not much news to report - haven't really had time to work on this much lately. I'd say the project is 95% done though, so I should really concentrate on getting it across the finishing line!
2025 ftw! 😀

Thanks for the info, looking forward for the finalized version. And thank you for your hard work, happy new year.

What incidentals would one need to procure once this TinyLlama 3 is ready. I have a Mister, but was looking for something more 486-ish dedicated for DOS/early-Windows and stumbled across this project. I am not family with the arduino or that chip that I am seeing at the github for the earlier TinyLlamas, but I would like to start gathering those pieces that I can while waiting... Would someone be so kind as to point me in the right direction? I'd love to see if I can get my 80's BBS back up and running!

Hello there,

If you want to get something soon and have most of your needs covered, I suggest the ITX Llama (https://github.com/eivindbohler/itxllama)
There is a discord server https://discord.gg/5Xwj6pAF for a group buy if you want to get it cheaper. If you are willing to spare more money to have one sooner, you can always take the gerber files and have it PCBA via different manufacturers.

Does anyone know how the Vortex86VGA and SM750 fare in compatibility in DOS games/resolutions? I was looking at this famous chart and didn't see them listed.
eg. Do they work with Commander Keen 4?

yes!

My experience:
-With Vortex86VGA: Doom is slow, Superfrog has tearing, Lost Vikings runs perfectly well.
-With SM750: Doom is smooth and fast (constant 35FPS, which is what Doom tops into), Superfrog is perfect, Lost Vikings has broken scroll.

For all the other games I tested (Lemmings, Prince of Persia, Another World, Lotus III, Alone if the Dark, Heimdall 2, Jill of the Jungle, and many, many more) perform the same with both VGA adapters.

What won't run is Lemmings 2 with music and sound effects, but that's because a BIOS-level bug with regards to EMS on the Vortex EX SOM.

EDIT: To run "Lemmings 2" and "Elder Scrolls: Arena" on the TinyLlama (or any other Vortex86 EX SOM platform), add this in CONFIG.SYS before the EMM386 line:

1DEVICE=C:\DOS\SMARTDRV.EXE /DOUBLE_BUFFER

This line alone fixes the compatibility problems that EMS programs exhibit on the Llama boards 😀
