Microbaud MLDL anyone .. ?

[ThomasF]

Hi,

Years ago (many) I bought a MLDL box, developed M-Code etc for the 41 and even modified it by adding more memory to it.

I recently found the box amongst my other old 41 stuff, but I can't get it to work anymore.

The PCB itself is marked "(c) Microbaud Developments Machine Language Interface '82 HP-41", and on the backside it says "(c) 1982 Microbaud Developments", "ML I VER. A" and "Made in Aust", and if I remember correctly I bought it directly from Australia back then.


This MLDL is probably very close to the original by Lynn Wilkins, so I might be able to reverse-engineer the PCB - but is there anyone out there who might have a copy of the schematics for this version of MLDL?
Googeling has not given me any clues about the card (apart from a similar question on this forum back in 2004 with no responses), but any scans of some schematichs might help!

Best regards,
Thomas
