Sinclair ZX80 / ZX81 / Z88 Forums

I have got a load of Memotech Interfaces from someones shed outside of their nice cases.

Here are my gueses as to what they are, anyone fill in the blanks or correct?

MT05-XX 32K Ram
MT06-XX Unknown
MT07-XX Centronics
MT08-XX RS232
MT09-XX 16K Ram
MT10-XX Keyboard Buffer

Can you take some good close up pictures please

Mark

This was my plan, some of the interfaces have obviously been modified post manufacturer.

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.

regards Andy

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.

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

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!

I finally got a chance to photograph and upload the pics for these interfaces.

Enjoy!

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?
