| Photo of the "fabled" MTX
in a red case!
This one is an imposter though, it is a standard MTX512
with one of the red keyboard covers fitted, rather than
one of the demo machines built for the Russian bid.

| MTX512-S2 (Series 2) The extra length
on the left hand side is the optional SDX Disc unit with
in-built 3.5" floppy disk drive.
You can just see the composite video connector from
the optional 80 Column Board on the right hand end
plate. |

MTX512 Undeveloped Prototype This is an extended
length MTX, some 3 1/2" longer than the standard MTX.
I don't think that the prototype ever made it into
production.
Geoff Boyd commented "I believe this was a (very)
limited run of MTX 512s with single drive Floppy disk
Controller card and 80 Column card in the extended
enclosure."
Other than the standard MTX computer board, the
machine shown has no additional internals fitted.
The machine has no serial number and the rear panel
identification labels are missing - supporting the
theory that this was a prototype model.

| An interesting photo of an MTX500 (it
must have had at least a 32k RAM expansion board
installed) and a twin 5.25" floppy drive FDX. This items
was sold on ebay Germany in 2012. The floppy drives
are not the standard Qume type, they look to be Epson
SD-521. The motor in the SD-521 is direct drive, rather
than the belt driven Qume. |
 |
| This is the single drive FDX listed at
the same time as the MTX500 above. This is a true FDX,
single drive, model with an 80 Column board and
supplying power to the MTX, rather than the "budget"
single drive, non-CP/M version. I would have expected
the single drive to be on the left, on the twin floppy
CP/M version, the drives are "B" and "C" - "A" is mapped
to the boot drive. |
 |
| Rear view of the FDX above, showing the
power connections on the left, the monitor connections
on the right and the expansion port cut outs in the
middle. This FDX is unusual in that it has an actual IDC
for external 8" drives, rather than a blank cover on the
expansion connectors as most FDXs have. |

detailed photos of the inside and outside of different
FDX models is on the FDX

| MTX500 On the cover of "Your
Computer," June 1983
This was prior to the launch so I'm assuming that
this was an early prototype. The keyboard layout is as
per the production model, but the colours and Memotech
logo are not and the MTX logo is missing. If you look
closely, you can see what became the "BS" key is
labelled in full on this keyboard, the Function Keys are
numbered from "F0" to "F7" instead of "F1" to "F8"and
the reset keys are identified, rather than having blank
key tops as in the final version. |

The Design is now the same as the original
advertising brochure, the logos were changed again
before the machine made it into production. (See the
articles page for
