However, with the Atari 400 and 800 and the Exidy
sorceror, the BASIC ROM
module was, IIRC, included with the
machine in the standard configuration (i.e. if you bought an off-the-shelf
boxed version of one of those, you
got a BASIC module). Is that really any different from having the ROMs
to the main PCB?
My Sorcerer came with the BASIC cartridge supplied as standard as did the
one a colleague got. I also recall that this was the standard offering.
