Any cirrus logic gd542x isa/vlb project around?

Beut, I've got a feeling I've got a salvageable CL chip on an otherwise screwed up NEC powermate motherboard.
Unicorn herding operations are proceeding, but all the totes of hens teeth and barrels of rocking horse poop give them plenty of hiding spots.

Super cool
Found a ISA CL-5434 Video card project on PCBWay

Came across this little Project

Right to repair is fundamental. You own it, you're allowed to fix it.

I have a number of open source vintage computer projects.
These include CPU drop-in replacement boards for the 6502, 6509, Z80, 8088, 68000, 8051, and a few other random projects.

Please add the Picovox project to this list.
It is a device built on top of Raspberry Pi Pico 2 capable of simulating not only Covox, but many more sound devices intended for the LPT port. As of now there is at least partial support for Covox, FTL sound adapter, Stereo-on-1, Disney Sound Source and OPL2LPT, with support for at least CMSLPT and TNDLPT planned.
[..]
Since this device is basically Pico 2 connected to the LPT port, we may add support for more features. Support for (emulating) Digispeech DS311 and DS301 devices, MP3 playback by sending raw data over the LPT port, and even some non-audio features such as printer emulation with saving PDFs.
It's in early stages and no sources or designs have been published yet, but @jansakos has stated that he intends to do so, once some of the basic features have been implemented.
There used to be a project called RTVGA, an 8-bit ISA VGA card built with RTG3105iEH.
The source (presumably KiCad) was in this repository: https://github.com/spark2k06/hardware/ (now gone).
Mentioned in these threads: Re: Arrived ISA 8 bit RTVGA boards and Re: RTVGA 8 bits on PC/104 socket and converter to ISA with MonochromeVGA.
Anyone has archived the source?
