Bought new (1983) |
My original Memotech "MTX512" computer. It has 32k of RAM
on board and a 32k memory expansion card soldered to
the internal edge connector. |

|
Bought new (1984) |
My original FDX. Originally supplied with 2 x
5.25" QumeTrack 142 floppy drives (Memotech
Type 03) , I have
replaced them with 2 x 3.5" Sony MPF920
drives (Memotech Type 07) and have
replaced
the PSU with an ATX type.. |
 |
| |
| Additions
from more recent times |
| The three items purchased off ebay
in 2009 all came from an ex-lecturer at
Hartlepool
College of Further Education (HCFE). He "liberated"
this equipment, with a load of other stuff, when the
college stopped using them for teaching. So, we
know of at least one place where the MTX computer
made a successful bid to beat the BBC Micro's
dominance in the education market! This is
the HCFE label attached to the case next to the
Memotech serial number. |
 |
|
HCFE has itself now been replaced - a new campus was
opened in 2011. I would guess that the MTX equipment
was cleared out in preparation for the move.
Logos from the 1980s, 1990s and the present day are shown here. |

MTX512
Has now been
upgraded to 64KB on board |
18997 |
ebay uk
(2009) |
Purported to be an MTX512 that was used to run
the FDX bought with it. It only had 32k of RAM
installed - it was an MTX500. Has
had horrible HCFE
markings on the top. |
 |
| Not perfect, but it looks a lot better now.
Cleaned off the red marks, but there is still a
slight sheen where the writing was. |

FDX bought to replace my broken one, was
supposed to run with the "MTX512" I bought with it,
it was sick for a while, but has now been repaired -

REMEMOTECH |

Bought new
(2012) |
I bought an Altera DE1 and loaded Andy Key's
remarkable REMEMOTECH on it. Andy made me a nice
label like the one in the photo too! |
 |
| MTX512 |
15189 |
ebay uk
(2012) |
Bought to replace the pseudo MTX512 to run the
second FDX system. In pretty good condition, but with a
slight blemish on the keyboard label. |
 |
|
MTX Memory Card |
n/a |
Andy Key
(2012) |
After having
botched a memory upgrade to my
MTX500, Andy generously gave me one of his "home brew" MTX
Memory Cards. You can see the 512K memory chip in
the photo. |
 |
|
REMEMOrizer |
2 |
Andy Key
(2012) |
Another great modern day add-on from Andy Key
that I just had to have! So much so, that I got
Serial Number 2 :-)
My MTX has a noisy clock signal, so Andy made a
fix for this in the code - the red dot on the GODIL
shows that it has been upgrade to software
Version 2. |
 |
| MTX500 |
17815 |
ebay uk
(2013) |
Bought to get the MTX 80 column card (below).
It has 64k of RAM installed - i.e., it was actually an MTX512.
Very "bouncy" keyboard. |
 |
MTX 80 Column Card
The 80C card has a "Retest" label and is
identified as "40085" but this is not the original
serial number. |
None
|
ebay uk
(2013) |
Installed in the "MTX500", has a really ugly
hardware hack on the video output connector (on the
top right of the card). |
 |
| The purpose of this hack is not known. Peter,
thinks that it could be a very simple mixer that
adds the RGB and SYNC signals, but why would you? |
 |
| This example is soldered to the MTX internal edge
connector, making its removal somewhat problematic! |
 |
| The modified endplate showing how the RGB
monitor socket has been relocated to make room for
the video bodge job. |
 |
| SDX
Controller |
24985 |
ebay de
(2013) |
An example of the first version of the SDX
floppy disk controller. The controller did not
have the stand-alone floppy drive that would have
been supplied with it which also provided additional
5VDC to the controller. |
 |
| Rear view showing the FDD ribbon cable
connection and the 5VDC input supplied by the PSU of
the original Memotech floppy disk drive. |

Video Wall Hardware A range of modules badged "Cameron
Video Systems" and "Memotech" |
|
ebay uk
(2013) |
I didn't think that I'd ever get my hands on
Video Wall hardware, so when this came up on ebay I had to go for
it - and won! This photo is from the ebay listing,
a better set of photos can be found on
my Video Wall photos
page. |
 |
|

(2013) |
An added bonus thrown in after the seller of the
Video Wall (above) found it after posting the advert on ebay! |
 |
|
Games ROM Board (GROM) See
below for an example with the
Demo ROM installed. |
|
(2013) |
Jim Wills sent me two of these after Memofest
2013. I hoped to use these boards to set up a Memotech
Node Ring, but failed miserably. |
 |
|
It turns out that these boards are assembled
for internal mounting and thus not compatible with
the Node ROM. For the explanation, see their
description on my MTX
Options page. |
 |

REMEMOrizer |
15 |
Andy Key
(2013) |
The edge connectors that Andy needs to build
REMEMOrizer are obsolete and as there was some
uncertainty on the continuing availability of
REMEMOrizer, I decided to get a second one while
they were still available!
Excellent salesmanship by Andy, the connectors
are readily available at the moment :-) |

Private
sale
(2013) |
Bought this one from Diarmid after he'd found
the website and given us lots of missing software
and cover scans. |
 |
| The computer separated from the SDX disk
controller and drive. As you can see, cosmetically,
it is in very good condition |
 |
| Unfortunately, the internals were not quite so
pristine. You may be able to make out the corrosion
around the VDP & VRAM. |
 |
| The main computer board, there was a fault on
the VDP output that took a
bit of work to fix. See
this page
for details. |
 |
| The internals after replacing the VDP & VRAMs
and cleaning up the computer board - hopefully, you
can see the difference? |
 |
| Solder side of the computer board PCB, showing
the link wires, in this case red, to enable the 256k
of system RAM. |
 |
| The 80 Column card. This one has not been
soldered to the motherboard edge connector. It
does not have the RS232 ICs fitted and does not have
the external power socket fitted. |
 |

SDX Controller -
"new" |
32074 |
Private
sale
(2013) |
The "new" style SDX controller with integral
3.5" drive. To incorporate the drive, the profile of
this SDX is much "squarer" than the MTX and original
SDX controller. |

Gillian MacKenzie
(2013) |
This machine is in immaculate condition, with
original outer and inner boxes & polys. The
keyboard is particularly impressive - maybe even as good
as it was when new! |
 |
| The internals are also pristine - certainly the
best preserved MTX motherboard that I have. |
 |
HiSoft Pascal ROM
MTX Version 1.2 |
15021 |
Private
sale
(2013) |
Bought a Pascal ROM board
from Peter when he was thinking of getting rid of
his MTX - he decided to keep the MTX512 and sell me
the ROM board - great! |
 |
| The ROM board has two 2764 (8k) ROMs fitted for
Pascal, leaving two spare slots. Solder side of
the board. |
 |
| MTX Screen output from the Pascal board, after
typing "ROM 2" <ret> All I need now is to learn
Pascal ! |

MAGROM |
None |
Martin Allcorn (2013)
Production
PCB
(2014) |
During development of his
MAGROM
games ROM, Martin generously donated a Version 3a
prototype board to me ! The display is from a beta
test version of the Menu, with 38 available games. |
 |
| Component side of the development board, with
all of the components, apart from the ROM, mounted
on this side. |
 |
| Solder side of the board, showing the ROM and
Martin's neat soldering work. |
 |
| My "production" version of MAGROM. It is a
little bigger than Martin's prototypes, but the PCB
was designed so that it can be installed externally
or internally.
This required a horizontal form factor with the
components located at the back of the board, in the
deepest part of the MTX case. |
 |
|
MTX Speculator |
None |
Martin Allcorn (2013) |
Courtesy of Martin, at long last, I now have a
Memotech Speculator, complete with original program
tape. |

dead FDX. |

Andy H. & Dennis W. (2014) |
Another
generous donation, previously owned by a colleague
of Andy & Dennis.
No leads
or manuals, but both are in excellent condition. The
MTX works fine but the FDX PSU blew a capacitor
about 30 seconds after I turned it on. Not a great
surprise and
easily fixed.

Came with no PSU, fully working, but the keyboard is
very rough - likely due to lack of use. |

Self
(2015) |
My "production" version of CFX.
With a
similar form-factor as
MAGROM,
allowing either internal or external mounting. |

Video Wall Hardware A complete 4x4 Video Wall
system |
|
ebay uk
(2015) |
This system was advertised on ebay UK in September
2015. I managed to do a deal with the seller and
picked it up from Birmingham.
The system was
installed in a flight case, so I assume that it was
originally used for mobile events.
Detailed photos are
available on a dedicated page. |

Generously donated by Vic. Fully
working (though 1 "noisy" key-switch needed to be
replaced). |
 |
|
This one is very clean inside and out, the photos
don't really do it justice. It came with its
original box and polys, as well as a dust cover that
was likely used to keep in clean when it wasn't in
use. |

have one in the collection.
