Unfortunately AT&T does not sell the BLIT. They sell the 5620.
The BLIT had a 68000, the 5620 for political reasons has an AT&T custom
processor chip. (It's probably more expensive for them to build it
than to buy the 68000 from Motorola for $10.)
The ST cartridge in question makes the ST emulate a BLIT. In fact,
once a few changes have been made to the BLIT sources, it can run
the same binaries that a BLIT runs. (The changes make things like
the screen size a parameter rather than hardwired in.) All the BLITs
in the world are inside Bell Labs and a few universities.
I guess this might benefit people inside Bell but it's useless to the
rest of us, unless AT&T releases BLIT (not 5620) software to everybody.
Hmm, AT&T could probably sell the 520ST cartridge and the BLIT source code
as a package deal...
