MTX512 | 4000-05 | 64 | 64 |
This is an MTX512 with 64kBytes of RAM This computer also has a hand written label next to the original Memotech label. The second label has the number 17095 and the date 25-10-84. I think that perhaps this machine may have been returned for repair and given a new serial number? |

"bounce" which I will replace. The original serial number is accompanied by an additional red label serial number,10555 (3/9/84), presumably added after repair / replacement. |

The 80 Column board has a non-original serial number label, marked as "Retest 40085". The keyboard in this machine needs a good dose of looking at - it is very bouncy to the point of being unusable. |

Either a MTX500 was installed in an MTX512 case, or a 32kByte memory expansion board had been removed after it left the factory. I have upgraded the installed RAM to 64K. |
