FTGH (you come get): VAXstation 100 terminals

by cctalk＠ibm51xx.net

You snatch two - 1 for now and 1 for backup :). Plus it is in your neck of the woods or dessert to be more accurate. . -------- Original message -------- From: "Mark J. Blair via cctalk" <cctalk at classiccmp.org> Date: 3/6/17 8:18 AM (GMT-08:00) To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: FTGH (you come get): VAXstation 100 terminals Ugh, this leaves me feeling so conflicted. One or more of these rigs sounds so tempting, but both my house and my 11/730's Unibus cage are full. Do I stash one in one of my sea containers in the hope that someday find time to let it timeshare a desk in my house, and also find a place to plug it in? Or do I do the sane thing, and pretend I never saw this posting? :) -- Mark J. Blair, NF6X <nf6x at nf6x.net> http://www.nf6x.net/

UNIBUS RK611 (RK06/RK07) controller available

by jnc＠mercury.lcs.mit.edu

So I have a complete RK611 (backplane and boards, no cables, sorry). I doubt very much I'm ever going to have any RK07's to use it with, so it's available if anyone has a use for it. It seems to be in reasonably good condition, but I have no idea if it's working or not. Noel

I hate the new mail system

by jnc＠mercury.lcs.mit.edu

> From: Christian Corti > My complaint ... is, that if you reply to a message on the list, the > author of that message gets a private mail, too, as he is listed in the > Reply-To:-field. This is *wrong* and must be corrected (i.e. removed)! Good grief. Just about every email from every mailing list I'm on which I reply to, I have to manually remove additional addresses from the reply. It takes about one second. Just deal with it. Noel

PDP-11/34 rails?

by jnc＠mercury.lcs.mit.edu

(I don't think any of the 5-1/4" boxes could rotate.) The BA11-K had that incredibly heavy H765 power supply, maybe it was too heavy to safely rotate? > I'm not sure what the original part number or manufacturer was. Anyone > have this information handy? Anyway, I've seen BA11-K boxes with several different kind of mounting slides. The tall, grey-coated ones are made by Chassis Trak, a division of General Devices of Indianapolis. The 4 I looked at, all idential looking (except for handedness), all had different numbers on the CT sticker, so I don't know what the model number is! This one says '060RH'. I've also seen BA11-K's with narrower (height-wise) slides, in some sort of bright metal finish. I don't know who made those. GD is still in business; I looked on their web site and found similar slides. I didn't order any because they were kind fairly pricy. BTW, does anyone know that they grey coating is? Is it some sort of phosphate plating, or perhaps some sort of early powder coat, or what? Mine are rusty, and I'd like to blast them and get them re-coated, but I can't figure out what that coating is. Noel

Rack-mounting a TU56

by ard.p850ug1＠gmail.com

I have been given an H960 rack :-). I intend to use it for my PDP8/e system (currently piled up, not connected), which consists of the : PDP8/e processor, Full of cards, memory extension, EAE, 32KW core, boot diode matrix ROM, RK8e, RD8e, RX8e, PC8e, etc. PC04 paper tape punch/reader (acutally, I converted a PC05, but that doesn't matter here) RK05 (well, there's an RK8e in the backplane and I have a spare RK05 so I might as well use it) RX01 TU56 (single drive version, ths is not a TU55 as some have suggested!). Various PSUs and step-down transformer for the TU56 and PC04 I think I have the right slide rails for the first 4 units too... Anyway, does anyone have experience of rack-mounting a TU56? It clearly doesn't go on slide rails, it bolts directly to the rack (hinge down the front panel for access). I have the manuals from Bitsavers, they imply there is some kind of spacer block that goes under the TU56. Does anyone know what that is exactly so I can attempt to make one if it is needed. -tony

I recently acquired a HP 9825 and have a project planned that will need serial i/o. If anyone has one of these interfaces they'd care to sell, I would be interested in visiting about it. Thanks, Tom

PDP-11/34 rails?

by jnc＠mercury.lcs.mit.edu

> From: Pete Turnbull >> I'm not the sure BA11-K (10-1/2" box) mounted 11/34's could do the >> rotate thing > The two I've had .. both rotated. Ah, right you are - brain fade, late at night. I went looking in my BA11-K collection, and found a couple that do have the rotate - the part that bolts to the box has a huge 3/4 circular plate, and a metal strip that runs to the front of the box with a huge (~3") handle bar at the front, which releases it to turn. I have this bit set that the outer slides (the parts that bolt to the 19" rack) are the same for the rotating inners, and the non-rotating ones (as used on, e.g., the RK05 and the BA11-F). > I've also seen BA11-K's with narrower (height-wise) slides, in some > sort of bright metal finish. I don't know who made those. I went and had a look at some, but there is no name, or number, anywhere on them. BTW, these also rotate. Noel
