E&S things

First, a question. I've got a pair of E&S digitizer tablets, twiddle boxes, and keyboards. The tablets are supposedly RS-232 and use an 8pin minidin. Is that the same type as Macs and Sun IPCs use? If not, does anyone know a pinout? The twiddle boxes and keyboards use 'RJ45' 8-pin modular connectors. Does anyone have the pinout for those, and know if they're just RS-232 or ...? I have a single box that will take a few peripherals plugged into it (kb, mouse, digitizer, twiddle box, other things I don't have), and connect to the E&S PS/390 I'm guessing. Anyone have a pinout for the 'uplink' connector on that? I think the connector is a DB25F, so it might just be plain RS-232 (which is my hope). Next: I've got some stuff I got that I have no use for. First offer for $10 + box + shipping gets each item. (Covers what I paid for them) Item 1: E&S PS/390 'scope' monitor cables. 9-track 10" magtape that is the VAX host software for interfacing with the PS-390s. A pair of 5.25" floppy disks that are copies of the software that runs on the PS-390s. If you're intersted, I can see what the label exactly reads Item 2: Manual: PS 390 Advanced Programming (marked AP) Manual: PS 390 Reference Material (RM) Manual: PS 390 Graphics Tutorial (GT) Manual: PS 390 Introduction and Support (IS) Manual: PS 390 Tools and Techniques (TT) All the manuals are in binders and are thick and heavy.
