There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer later in the year.

Re: Memotech Interfaces
This was my plan, some of the interfaces have obviously been modified post manufacturer.
Re: Memotech Interfaces
like 1024Mak says some picture to help identify would be of great assitance, myself i can only confirm that the MT09-xx is indeed a 16K dynamic memory pack.

what's that Smell.... smells like fresh flux and solder fumes...
Re: Memotech Interfaces
MT06-03 is the Hi-res pack, MT07-02 the Centronics, MT09-02 the 16k rampack.
Pity You haven't got MT11-02 the Z80 assembler pack, the most useful of the lot.

EDIT MT11-02 is also the part no for the Memotext word processor, but as the board is identical except for the omission of a chip here and there it's understandable.

Re: Memotech Interfaces
Peter has the memotech manuals on his pages. Maybe that might help to identify the modules:

Re: Memotech Interfaces
Thanks that fills in the MT06 gap for me. Its in pretty poor state and prevents the zeddy booting so I think it needs some TLC!Moggy wrote:MT06-03 is the Hi-res pack, MT07-02 the Centronics, MT09-02 the 16k rampack.

Re: Memotech Interfaces
I finally got a chance to photograph and upload the pics for these interfaces.

Re: Memotech Interfaces
Very nice ... What a haul! Do you think the seller had some connection with memotech or was he simply a fanboy or perhaps authorised service agent or somesuch?
