Hi folks, I just stumbled across two RP02 and RP03 disk drives (2 RP02, 1 RP03) in probably repairable condition. We have all cables (power, "bus", "unit") needed to hook the beasts to a RP10 controller of a pdp10. Thinking of restoring and connecting them to a Unibus pdp11. The issues: - No controller - No media (RP02/03 use the same pack) - No information I currently don't even know if there's a special sector layout for pdp10, pdp11 etc. (like with RK05 drives). Or if there are any RP11 (or RP211?) controllers around. Does someone know anything? Have documentation? Have a controller? Packs? Does someone know anything about pack compatibilities? That could help a lot! The packs seem to have 10 disks and two half disks (only one surface used). I have not seen one. Any hints welcome. Best wishes, Philipp :-)

DEC RP02/RP03 issues

by mross666＠hotmail.com

corestore here.... yes I have an RP11, and an RP15. And as of a couple of weeks ago, I have an RP02 and two RP03s! Strange that they should now turn up in two different places almost at the same time. Keep me updated - I intend to get my drives working, if you decide you don't need your drives any more, talk to me first! I also have RP04s, which are almost as interesting, but have a massbus interface which makes them a lot easier to get working...

For the swedes: Free digital LP25

by pontus＠Update.UU.SE

Hi At work we have a non-working LP25 that is threatened by dumping. It wont go away soon, but at this time next year it is probably gone. I'm told it suffers a standard fault of a worn out drive wheel. If you want it, its free for pick-up. http://vt100.net/docs/tp83/full1602.jpg Cheers, Pontus.

Andromeda Systems (ebay)

by tshoppa＠wmata.com

Andromeda sold some cool Q-bus chassis with drive mountings and power supply integral. I think the one in the E-bay auction is two 3U sized cabinets either just sitting on each other or maybe screwed into each other. One cool Andromeda product that was available for a while in the mid-90's, had power supply, room for a few 5.25" and 3.5" drives (I think by default with hot-swap caddies... that may have been just added on though), and a Q-bus chassis all in a desktop small PC-clone style case. With just two cards (a Mentec CPU with 4MB memory and serial lines + an Andromeda SCSI controller + Ethernet, a tape drive, a floppy, and a couple hard drives) it was a neat, almost laptop-sized PDP-11 development environment. That came in really handy when I was traveling all the time. Tim.

Vintage Props for auction

by wmaddox＠pacbell.net

This one looks like it may have pieces of the front panels of early computer gear. Pretty dirty, but if I were in the area, I'd probably check it out and see what it is. http://www.sellauction.com/ga/EVENTS/GA073109/IMG/5069.jpg These look like they may be racks of real gear, rather than gutted-out facades, but who knows? Looks more like instrumentation than computer stuff. http://www.sellauction.com/ga/EVENTS/GA073109/IMG/5087.jpg http://www.sellauction.com/ga/EVENTS/GA073109/IMG/5088.jpg --Bill

Looking for early versions of Symbolics Genera (or other 'bolix software)

by derschjo＠mail.msu.edu

Anyone out there have versions of Genera prior to 8.1.1 they'd be willing to share? I've been playing with my 3630 and I thought it would be interesting to load older versions of Genera to play with. I'm also looking for other software to run on Symbolics machines -- I have the 8.3 distribution set from David Schmidt which includes Statice, Concordia, Joshua and DNA, as well as the S-Graphics package. Any good games? :) (Also: if anyone knows how to get a "new" ESDI disk up and running on one of these things, let me know... I'm guessing I need software I don't have to do so. I have a nice 760mb drive I'd like to put to use, but I can't find documentation on how to do anything other than a low-level format.) Thanks, Josh

Also, there are D-sub connectors on the back that look like they are for connecting terminals or other I/O. I bring this up because of a few references I dug up on the internet that link Andromeda Systems with DEC-compatible gear. My guess is that this is an LSI-11 system, but it's just a guess. --Bill

PDP11/34a resurrection help

by jplist2008＠kiwigeek.com

Greetings all; I've had an 11/34a in the basement for some time now, but haven't ever had it "working", nor have I messed with it in several years - which, of course, means I've forgotten almost everything I ever knew about them, which is almost nothing, so I'm starting from scratch, pretty much. My 11/34a used to run a Xerox laser and came with a CDC9762, the card cage looks like this: AAAAAA BBBBBB CCCCCC DDDDDD EEEEEE FFFFFF 1 M8266 -------------------------------------------| 2 M8265 -------------------------------------------| 3 FLIPCHIP 4 M9301 YJ-----| M7856---------------------------| 5 National Semiconductor Memory Board--------------| 6 G7232---------| 7 G7232---------| 8 G7232---------| 9 M9202--------| G7232---------| 10 M9202--------| X031-| 11 X020 --------------------------------------------| 12 X030 --------------------------------------------| 13 M7843 -------------------------------------------| 14 FLIPCHIP 15 FLIPCHIP 16 FLIPCHIP 17 18 19 20 21 22 23 M9302--------| AAAAAA BBBBBB CCCCCC DDDDDD EEEEEE FFFFFF (Where slots 1-9 are in the right-hand backplane when looking from the front, and 10-23 are in the left-hand 14 slot backplane, which M9202 bridges between) I've got the DL11-W set up in the same manner as the 300bps example in the 11/34 Users Manual (and the DL11-W Operators Manual), and at this time I have the three X* cards as well as the M7843 card removed as I don't believe they're required for boot. I've verified on the backplane that +5 sits at a steady +5.06VDC and -15 is at -14.86VDC. I do not possess an o-scope, so the best I can do is with my multimeter. I have two problems. The first is that I do not own a "proper" cable that goes from the DL11-W to a terminal. I own a VT240 and have crafted a cable that goes from the Berg connector on the DL11-W through a header to a DB9, which connects to a DB25/DB9 expander on the back of the VT240. Obviously I've verified the VT240 is in 300/8O1 as required. To go from the flat-ribbon to the DB9 I have what used to be the header from a CDROM drive and have soldered the RX/TX/GND lines on the DB9 direct to the pins on this header. Currently it looks like this: BERG DB9 B 5 GND F 2 RX J 3 TX I -think- this is right, but I'm not positive. If I'm doing something stupid, I'd sure love to have someone point it out. Booting the 11/34a gives me nothing on console, but... Even if my cable works the 11/34a doesn't seem to be acting like it is supposed to. From my reading of the User Manual on power on, with the front switches set to CONT and the BOOT/INIT switch toggled to INIT and then let go, I should get the RUN light to blink out and then come back on and stay on. When I power on the unit the RUN light comes on momentarily, and then goes out. When I toggle BOOT/INIT the light flicks on, and again, goes out. I'm suspecting this means that somewhere the 11/34a is halting. If my console worked, perhaps I would get something to it - although, for all I know the console does work and the 11/34a is dying prior to it spitting something out. I would love any and all input as to how I should proceed. I'm reading as much as I can, but I've got a long way to go and help would be greatly appreciated. My thanks; - JP
