Thanks to Google and the MSX FAQ (great work, manuel !) , I have a part of the answer :
MIRC: IR receiver/sender
Created by Byte Wizards
So now the difficult part is the year and who is hidden behind 'Byte Wizards' ....
mars2000you is in the right direction, although he still hasn't got the correct answer on what MIRC stands for...
is this a "MIRC"?
Mouse Interface Remote Controller ??
afaik that thing is called ReMouse, not MIRC...
hmm, didn't see manuel already explained what MIRC stands for...
sounds like it's hint-time...
Unos hintos coming up 
Ok... the blur was quite revealing... we now know we're talking about
MCCA's Infrared Remote Control
is that a 1995 I spot?
And... is Alwin Henseler one of the people involved? (Oh no, he was in Enschede, right?)
MIRC explanation, correct
1995, correct
and for the person(s) involved... TBW was one of the person's nicks.
TBW -> A. H.
The other is P. O.
Pascal Oldenzeel?
