Yes, they look very much like the Centronics I/F in this album https://secure.flickr.com/photos/x0r4/a ... 402381338/
Edit: Looking at these pictures there seem to be both a MT07-01 and MT07-02 Centronics I/F.

Re: Memotext & word processing in general
Seems like the PAL can be read as well. http://primrosebank.net/computers/mtx/p ... _build.htm
Re: Memotext & word processing in general
HALT!
No need to read the EPROMs.
Fred Nachbaur has an article in SyncWare News Vol. 2 Num. 2 Page 6-8.
This article describes how to read out Memotext to tape, and load it in RAM at 8k.
It even decribes how to add extra commands like QIT to quit the program.
