Anyone use One Rom ?

Formerly called Software Defined Retro ROM (SDRR).

Hello adalbert,

Here is a new one to the list:
"...
I wanted to share a PC/XT motherboard I designed, based on the IBM 5160 and influenced by the many Taiwanese turbo clones of the era. I called it the DubaiXTClone.

The main differences from a standard XT design: 8MHz turbo with runtime speed switching, static RAM (no refresh), reduced IC count, 4-layer PCB, and real-time bus activity LEDs driven by otherwise unused gate outputs.

Fully open hardware under CERN-OHL-W v2 — schematics, PCB and PAL source code all included.

Tested with JUKO 2.31, Turbo BIOS 3.1 and others. SVGA Trident, 3COM, RTC, Floppy, and XTIDE all confirmed working in turbo mode.

As a side note, it also runs LMChat (https://github.com/spencer-uk/LMChat), a chat client that connects the board to a local LLM via LMStudio.ai application - ELKS and MS-DOS, both are supported.

Happy to answer any questions.

Thanks for the link @rasz_pl.

It has been brought up in other threads on Vogons, but suggesting this to be added here as well:

I just ordered one of these, it looks awesome in terms of modernizing an older laptop. Especially the network bridge piece of it.

Cool, this seems to be "must build" for my HP 200LX. I tried 2 old PCMCIA eth. cards, even able to load drivers and exchange few packets all attempts with mTCP failed, maybe due too excessive current load. Even better this adapter can combine network and storage and others. As this palmtop has only one slot and very limited internal storage so it's crucial. Going to check for PCB data to put some order in JLC...

Has anyone downloaded the files that were here?

it's gone now.

Here are the files I got from the repo back then (excluding the sisyphus-pci-backups folder as they are mostly unnecessary duplicates).

I did order a few PCBs and all necessary parts around early 2025, but I haven't really assembled a unit yet, as I'm still looking for a suitable 3D-printable bracket for this card's layout.

Without a good bracket I won't be able to actually put it into a case after assembly... even the brackets I could find online for the ES1868-ISA8 project did not fit that card and I had to manually drill more holes to adapt to its jack layout.

EDIT: There was a "low-cost" version of the card meant for half-height use cases. I'm only just made aware of this repo's disappearance.

EDIT 2: Turned out I did have the data about the "low-cost" version in my cloned local copy, the "LC" branch. Uploading it as well in case anyone's interested.

Thanks very much!

I looked closer but it seems not be opensource/openHW now:
$50 refundable deposit.
$160 expected final price.
Shipping in ~30-90 Days

You said its opensource, where are the files?
The repository will be made public prior to shipments. Many portions of the code are already publicly available via other products that there has been collaboration with.
