no more Keyboard System?

[riccardo]

Hi,
I neeed some top dividers for my old PS 3300s.
I found that a substitute for the original MM5824 are the Keyboard System
KS455 mini modules.
I sent an order via fax and also tried to contact them via e-mail, but I
had no answers.
Is there anybody who knows what happened to them?
And I would also like to know if there's another way to find a replacement
for the MM5824 (or better the original stuff).
Thanks
ciao
