Yup. Finally found working driver.
Only after 8? days, some reverse-engineering + "cheking it's guts up with other models of same era" ))
(i really lost count for time, ain't i...heh.)
Driver .EXE name is PenTablet_533-2.
By the default settings it works perfectly - no lost connection from pen to tablet,
pressure sensitivity working as it should be, mapping woking too,
Windows Ink (that is a little buggy, but helps sometimes)....
What should i say? Was it worth it?
For it's price - 'round 10-12$ on "russian craiglist" in "slightly used" condition...
It worth every penny. Cause you'll get a good piece of 'ware to work with.
And have fun reanimating it for modern software if it older than 14 years, definitely )))
But really... i'm glad i got it working again.
I suppose, now it's time for me to teach myself to draw in trad. again.... after some time. )
