I am looking for RSTS-11 circa 1972 to install on my PDP-11/10 machine. I am more interested in a "historically correct" rather than "more useable" system. I have a PDP-11/10 with 32kw core memory and an RK05 disk drive. My goal is to load RSTS-11 on this machine. I have scoured the internet, including rsts.org and Bitsavers, but I have not come up with an installable distribution. My plan is to use Ersatz-11 or simh to prep a virtual RK05 disk. When I am happy with the setup, I will transfer the binary disk image to my real RK05. I wrote a program that allows a binary disk image to be transferred via a serial port (I will release the source once I am successful in getting the machine running). My hope is that I can find a distribution (virtual tape, virtual disk, etc.) that I can use to install my OS. I am looking to learn and understanding the process so that I can become self-sufficient. Any ideas where to begin? --barrym

Last I looked (it been a while) a SCSI adaptor such as CMD is 4-500$ and suitable SCSI drives are cheap. Allison > > >-- >| Zane H.

Eurocard cases.

by afra＠aurigae.demon.co.uk

Hi group, Over the last few months I've been working on a clone of an old british home computer (Acorn Atom), on a series of eurocards, 3 at the moment. My problem is I'm looking for an enclosure for the eurocards, I have found a couple however they are not quite big enough, I figure some of the people on here might know where I can get such a beast from. I need to be able to house the current 3 cards plus a possible 4th. Cheers. Phill. -- Phill Harvey-Smith, Programmer, Hardware hacker, and general eccentric !

V5.4 sounds about >right for the cutoff. V5 was the cutoff for DEQNA, specifically it was DEQNA is unsupported and DELQA was supported. That really ment that if you ran a DEQNA and had problems with it they would tell you get a DELQA. It'also meant the code to run DEQNA was still there and it should work but to expect no software updates for that device and that device did run at reduced performance. I don't believe the driver itse;f was deleted till later possibly V6. Also the DEQNA was prone to failure, so if the system doesn't see it it may be cause it is dead. >> I also only have 7MB of working memory (total of 9MB but 2MB >> are considered bad by VMS) so it may not work well with later >> versions for lack of memory (not sure though). V5 or later works in 6 but very poorly. It should not be hard to find working ram to increase that. It could also be the over the top connector has failed. >Are you sure that VMS sees it as bad?

Well, in that case, I'd really recommend going with the ESDI, it would definitely be authentic, plus it sounds like you have all the bits and pieces that you need. I have a Webster WQESD/04, it's one of my favorite Q-Bus boards, as it is a very nice ESDI controller. One of the reasons I like it is because you can partition a hard drive up so that it appears to be separate hard drives. Zane -- | Zane H.

The VLC is actually my favorite VAX, I love how small it is. :-) Instead of a RD54 you might want to consider a different disk interface that lets you use ESDI or SCSI disks. It could very well be a cheaper alternative to the RD54, unless you get lucky. Zane -- | Zane H.

Anyone ever see a real KE-11A? (arithmetic peripheral for the PDP-11/20)

by ethan.dicks＠gmail.com

Hi, All, With the recent discussion of old PDP-11 core, I was reading over Warren Toomey's excellent description of piecing together the most ancient version of PDP-11 UNIX known, and dreaming of the day when I get my PDP-11/20 restored. I am missing, to my knowledge so far, two critical elements to getting the v1 UNIX kernel (and v2 userland) running on real hardware - an RF-11 and a KE-11A. I was figuring I'd have to make a hardware RF-11 emulator or tweak the code in such a way that some other device could be made to work in its place. The KE-11A seems to me to be a harder thing to replace with an alternative. I've read the manual on bitsavers and know the modules it's made of, but I was hoping to find a picture somewhere just to get a visual idea of its compexity. I know the general design of a number of 1970-ish DEC items, but mostly, I've treated Unibus devices as black-boxes - Unibus goes in, Unibus comes out, and in the middle stuff happens that does things. I guess I've been fortunate in that I've never had to do component-level repair of devices of that era (as opposed to lots of experience with older and newer gear). I've done lots of pre-OMNIBUS stuff, some OMNIBUS stuff, and lots of Unibus and Qbus single-card devices. The specific place I have little experience is with Unibus whole-backplane-era devices. The few that I've used worked when I plugged them in. So I'm not ever expecting to run across a loose KE-11A in the wild, so I have to consider what it would take to make one from scratch. Fortunately, it's a peripheral, not a processor option, so it's not festooned with attachments into the CPU itself (unlike, say, a PDP-8 EAE). I have lots of experience with making and debugging Unibus peripherals (COMBOARDs, among others), so I don't find that to be an insurmountable obstacle. I'm nowhere close to starting any sort of construction - I'm just hoping to find a photograph for now. Long before I'd start any sort of KE-11A project, I'd want to find a way to power up my three-BA11-11/20 (no authentic PSUs at the moment - those were harvested before I got the machine) and get it running. I'm expecting to be using XXDP and RT-11 to confirm that it works before I move on (fortunately, it's easy to drop peripherals like an RX11 on an 11/20 so I can import test programs from floppy or papertape as I debug any problems). Any pointers (in addition to bitsavers) on the KE11A would be much appreciated. I plan to tear into the changes made in simh to see how it works from a software standpoint, but the manual does have some good descriptions already. Thanks for any assistance, -ethan
