Eh, he's probably not. I love paper and I love scanning, and I dedicate a lot of space and time to both. I can't keep everything but I keep a lot more than one man without a warehouse should. I do know now, though, that when I get that big document warehouse (climate-controlled, of course) that I fill with every manual on Earth, with room for extra-planetary docs, should they survive the shipping process, it will be called the "Silverfish Motel". -j
Re: Osborne-1 with prototype-based motherboard
On 12/29/18 6:59 PM, Brad H via cctalk wrote: And then other boards used a 3A-xx number instead of the 2A2001 number. Kind of confusing. For what it's worth, looking at a photo, my[1] machine's board looks more like "3P10083 REV A" down by the front edge of the board, unless there's some dirt or other debris making it look like a 'P' rather than an 'A'. Unfortunately I don't have a photo of the entire board, so I'm not sure what the serial number top-left is (and if the data there typically differs from the data along that front edge). IC date codes appear to be early 1982, and the case is one of the more rugged 1a ones. [1] At least I think it's mine :-) I picked up two machines from another collector a few years ago, and one of them went off to another list member, so it's possible that the photo I've got is of that one. Interestingly the main Wikipedia article for OCC says that the first machines went out in July and they sold 11,000 in the eight months after that - but the article specifically for the Osborne 1 seems to suggest that systems went out in April (but again with 11,000 sold in the eight months after). The main article mentions a 10-15% failure rate, which seems incredibly high - presumably pressure to meet demand and repair faulty systems was enormous, which could explain how a prototype / early board found its way out into the wild.

RSTS source tape
Does anyone know the OFFICIAL status of RSTS/E source? I am aware of the Mentec license, but it appears to only grant a license to the binary distribution. I believe I have source tapes to RSTS/E version 5 & 6 that I would like to release copies, but I cannot until I can get official permission. I acquired the tapes from a person who did some development on early PDP-11's. I am checking my binary versions of the RSTS tapes and if they are ok, I can release RSTS/E V5B and RSTS/E V6B. --barrym

We have a few dupes here but reserving those for someone that might help us out. Another great reference are the old joint computer conference east and west books. were or became AFIPS WOW THEY HAVE ALL THE INSERTING EARLY STUFF! We have the stuff from start to the 80s as I remember... nothing newer.. a fine gift from Honeywell / Bull HN and some from side sources... some of the later hard bound ones we have some duplicates of... need to make a list.. The early ones we may be missing an issue ? will have to make a current list. These AFIPS publications are another group that are not in full open access on the internet as far as I know.. But should be! Some I like looking at for something different are the UK data processing Mags form the 50's and 60s as there are computer and companies in there I know nothing about at all.

Not sure how to contact them, though. V5B is quite interesting, since it's the first version that was built the way all the later versions were, using the RT11 runtime system. From V4A to V5A, system generation was done using DOS-11. (In V3 and before, as far as I know, there was no Sysgen, you got your software built to order by DEC, probably at least in part using TOPS-10 based cross-assemblers.) paul

I once sent some manuals to Bitsavers, and they duly got scanned. (Thank, Al, they came out well.) I didn't get them back. I don't think I asked for that, in which case it's reasonable enough that Bitsavers didn't go to the extra expense of returning them. It might be helpful to state the policy (or choice, if any) explicitly so people know what to expect. paul

PDP-11/45 RSTS/E boot problem
Hi all, Some here may know I’ve been working on an 11/45 restoration off and on for some time now. My ’45 currently has floating point, KT11-C mem mgmt, 124 kword MS11-L, and an RK11-C with one restored RK05 drive. Last week I decided to see if I could bring up RSTS/E on the machine. I managed to sysgen a minimal V06C system that can run off a single RK05 pack under simh, but when I transfer that image to the real hardware using pdp11gui it does not seem to completely/successfully boot. The “Option:” boot loader comes up and sub-commands there seem to be working (in particular, the “HARDWARE” sub command shows correctly detected hardware and options). When booting RSTS/E, after supplying date and time, the idle pattern starts on the front panel (but just the bottom part, on the data lights). When console is in display register mode, it shows an increasing count. Console input is echo’d, but the INIT banner and subsequent prompts are never printed and the read light on the RK05 flickers continuously as if the system is trying to read the same sector over and over. Figured I’d ping here in case this is a known failure mode to folks more familiar with RSTS/E? Also posted over on the vcfed DEC forum. FWIW, the machine is passing all MAINDEC CPU, MMU, FP, KW11, and RK11 diagnostics. Cheers, —-FritzM.

I’m sure they are if you travel to Seattle.
