Another case of rubber rot... I haven't had it happen to me (except rubber
feet, etc... most recently on a Sun type 5 keyboard... half the left
turned to goo... the one thing I've found that acclerates this (and damages
some plastics too), is certain vinyl? cabling... this type 5 probably had a
keyboard cable wrapped and in contact with it's foot. I've had some plastic
on computer cases/etc similarly damaged by prolonged contact with cables.
If you are only looking to read... find a newer drive.... I use a Wantek
525Meg QIC drive... it reads DC6150 tapes... and I'm pretty sure DC600
I have a bunch of QIC drives around... I'm going to have to start examining
the rubber rollers.....
I can imagine the old 45 meg ? drive for my Sun-2 is probably toast...
