The information on that Wikipedia page is so far from correct, i honestly do not know where to start..
I've spent a lot of time looking into the Panther, following Press reports from rumoured ST Console/ST+/Project robin, up to point of actual Panther Project.
Not so much from Hardware point of view, but games wise.
Everything i found is here:https://assemblergames.com/threads/the- ... etc.66307/
Basically there's never been a shred of proof, in fact it's been strongly denied by key Atari Corp staff, that Cybermorph and Crescent Galaxy ever started on Panther...
Jeff Minter's test demo routines were for his planned Star Raiders-esq Panther game.
Guildo H, had been working on an RPG called The Crypt for the Konix Multisystem, it was moved to Panther instead..talk about backing wrong horses.
Scott D.Williamson had coded a simple graphics demo.
Joel Seider had coded some enviromental tools etc.
Peter Johnson was assisting in the conversion of Shadow Of The Beast to the panther.
Hand Made soft were testing the system, had a version of Elite up and running on it.
Rob Zydbel etc were working on original games.
Tiertex had planned Strider 2 for conversion to it.
Domark were NOT converting Pitfighter as had been claimed.
Whilst Guildo H, Leonard Tramiel and Jeff Minter liked the hardware, majority of folks didn't think much of it, not much more powerful than the SNES, bugged, Nightmare to code for and would of been obsolete wthin 18 months.
The thread (and others of mine) attracted some rather unwanted attention from certain JSIII posters, but i felt folks had a right to know what was really in development.
