Pre TT? Lots of stuff and sockets on main board. Maybe development of STe?

Hmm, no cartridge port but a new one in front, a console development board with four joy port? 2 sockets for oscillators? It also says "ST PLUS" on the ROMs.

May be a Atari Transputer ATW800 Board, a Mega ST with four Link ports and SCSI ?

This is a pretty good photograph of the ATW internals, with the Mega board clearly shown: http://www.classiccmp.org/dunfield/atw8 ... w800i2.jpg

That's not what this is, except maybe in prototype form.

No need for a megabus on the ATW

There is a Mega ST Bus with J600 over the CPU. I can not find a Videochip. There is a 913 DMA. The Board has no SCSI. So that is not a ATW800 DaughterBoard. The Roms have writing ST Plus on the Sticker ...

For those of you who didn't already see it on Facebook: Based on the material I have, I hypothesized that this is a STE prototype. (STE was initially called STPLUS, like on the ROMs in the photo.) Curt Vendel has confirmed this.
