Specification as above but with the addition of an "internal"
65C102 4Mhz,
64k Co-Processor.
I have no details of this machine yet, but pictures of the interior
show a
"cut-down" specification. ie. no UHF modulator, Serial, Analogue,Cassette
port, no disc drive/Tube/1Mhz bus/user port. Only a Printer port
on the
underside. Also no Battery backed CMOS and fewer ROM sockets.
Master 512
The Master 512 has Identical specification to the standard Master
128
but with the addition of an "internal" 512k IBM 80186 Co-Processor.
This board runs DR-DOS ver 2.1 and comes supplied with the GEM
suite of programs by Digital Research.
Master Scientific
It is debateable as to whether this machine was "actually" released.
It is present in Acorn advertising at the time but whether the
Co-Processor
was actually an "internal" version I cannot say. The External
Scientific
was housed in a BBC Micro Co-Processor case, like the 6502.
It contained a 32016 Processor with upto 1Mb of RAM and ran the
PANOS operating system. It was mainly an academic tool.
