Memotext & word processing in general

[mrtinb]

Hang on! This is a MT07-02 Memotech Centronics Interface!

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.

CRAP I have confused this topic with another my apologies!!

MemoTEXT pics to follow.

TRY AGAIN!!

EPROMS 2716/2732

[mrtinb]

It seems there is:

• two EPROMs and
• one PROM

[1024MAK]

IC1 PAL14L4-2CN Programmable Logic chip
IC2 82S123N 32 x 8 bit (256 bit) PROM
IC3 2716 EPROM (2K bytes)
IC4 2732 EPROM (4K bytes)
IC5 74LS00 Quad 2-input NAND gates

Looking at the board, I’m guessing that the 34 Way pin header is a parallel (Centronics like) port.

Yes, but the OCTAL TRANSPARENT LATCH WITH 3-STATE OUTPUTS… is made to send datas to printer, not retrieve datas !

That’s what I meant

Seems like the PAL can be read as well. http://primrosebank.net/computers/mtx/p ... _build.htm

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.
