Looks like Pierre Cornier (@pcornier) has been working on a Tatung Einstein TC-01 core!

Excellent. A very MSX-like machine.
I have two machines here, they're monsters, and dwarf many 80s computers.

Was wondering what Pierco was up to, had been quiet for awhile, didn't expect this one - had thought he was working on Epoch Cassette Vision.

Pierre started uploading code to git a few days ago and is already working on the floppy disk drive.
Like the CoCo / Dragon, it will be a great core. Pierre does an incredible job.

At this moment the core synthesizes and starts the machine, it is exciting and I really want to see it work when it is finished.

It seems to me that of the holy grails, only the Grundy NewBrain remains to be implemented, with this Tatung Einstein TC01 core a fantastic collection of cores closes. We already have almost all of them in FPGA !!!

Pierre has updated the Tatung Einstein core with many improvements, although at the moment it's WIP and it starts and reads discs. Closer and closer. Very good news.

The Tatung Einstein TC-01 core have been officially released by Pierre.
It's wonderful as I expected.
Thanks very much for the core.

Thanks, only read about the Tatung so far, I am looking forward trying the core out (there is a version of Elite on this computer if I recall correct).

Thank you for this core. I tried a few disk games. They work very well. :)

You're right. JetSetWilly, Manic Miner, Highway Encounter, Oh Mummy, Chuckie Egg are native Einstein TC-01 versions. And Now Elite works fine with keyboard.

There are a lot o XBasic programs, even BBC Basic programs, Xtal, CP/M ... lot of fun !

Been wanting an Einstein for some Years and now it has arrived. Had one for a while in the 80's before passing it on to my brother-in-law.
Thank you Pierre and all who contributed

Thanks for this core! I have to try Lazy Jones!
Update: Sound is buggy but the game is playable.

Thank you @Pierco !

Hi @ron,
Have you already tried the Einstein Version 256 ? On my side I've this screen while the version TC01 works fine.
Could it be because I'm using the VGA out ?

It looks like a scandoubler problem. I think the new VDP chip for the 256 is directly connected to the scandoubler. I will look at it later.

Thanks @Pierco, been waiting a long time for an Einstein emulator as I could never figure out how to work the MAME offering.
Not sure if this will be helpful but the 256 Games Pack demo program doesn't seem to display correctly.

Edit: Think it's related to @Kathleen's observation ;)

Watching a real hardware stream tonight, Lazy Jones was played and the music was fine (it's static noise on the MiSTer core). I figured out how to get it emulated under MAME and the music on that, with the same disk image, is fine. Is this a known problem with the audio in the core?
Just about every other game he played matched the MiSTer core perfectly, even the ones that wouldn't load, so this a a damned close core, I'd just like to point out anything that might be missed :)

Might there be a couple of fixes for this Core at some point?
