 Scored !!
I went back to the dump today and found the missing cover-plate but no HD.
 BUT there was another 350 complete with face-plate, HD, and cables. It had
a handwritten tape "last used in Dec.xx/99" The RX50s on one had a label
pasted over a previous one dated 22jun1992. possibly reconditioned ?
 The previous owners were an international Gas corp. Since this is in the
middle of nowhere, that explains why they wound up here. Likely hooked up
to headquarters.

The cards are labeled 000401, 002004, 001002, 000034. The same on both
machines.

 What's W1 and W2 ?

 There's no KBds. but IIRC from postings here it can use the lk201's that I
have with my Rainbows. I also have VR201 and VR241 monitors which I
believe will work. I have some blank 5 1/4 DEC floppies and from discussions
here I can use a 'bow to format more for them.

 I have a DECMATE manual that had system disks but also a demo disk
which would work with my r'bow. I wonder if it might also work with the 350.

 With Tony D's strictures in mind I'll move cautiously before trying to fire
them up.
