Does the elbox a1200 keyboard adapter allow multiple simultaneous keystrokes?

Yes, I had some problems with pc-key 1200 and a4000T keyboard. Arrow keys didn't work simultaneous, so it made some games more difficult... and for example shift-ramiga-s combination didn't work.. then the whole adapter broke down and I had to buy new one. Bought Lyra instead and it works like a charm. Only downside is that had to buy PC keyboard for it.

ctrl-c and most that kind of combinations worked fine here. It was only some certain combinations which didn't... can't remember if I ever needed any other combination which wouldn't worked besides those I mentioned

Like that ramiga-s worked in ced (search forward), but shift-ramiga-s didn't work (search for...).
