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.
RD51? RD52?
RD52. Quantum 540 full-ht.
I am debating
whether it's worth the effort to go
back and find it or is it not too difficult to replace.
The RD50 is a real Seagate ST-506, the RD51 is an ST-412 and the RD52
is one of several 30MB MFM drives including a Quantum 540. How hard it
is to replace is up to the scarcity of MFM drives in your area.
It has 4cards in the cage and the 2 daughter
boards.
Mine has a full boat: a double-card video card set, two CTI bus RAM cards,
a floppy controller and a hard disk controller. I'd give handle numbers,
but they are not here with me.
Those daughter cards can be upgraded from 128K to 512K
by replacing the
4164 DRAMs with 41256s and adding W1 and W2. Not sure if you pull both
cards and install one upgrade or if you can install two 512K cards; haven't
tried it yet.

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.
