I received an email from plebourgeois at me.com who said he's in
Mandeville, Lousiana and has an Osborne available with
accessories/manauls to a good home for the cost of shipping. He said
he'll throw it away if he does not find a home for it soon.
That's all I know, do not reply to me or this list, send the guy an
email directly.

They didn't do two different console PCBs, did they? It must be just cabling
routing? I couldn't find any manual/drawings for the BA11-K version, so I
can't tell for sure..

That approach worked really well for Dave B and I on the QSIC. IIRC, we
bounced around the uengine design concepts for a couple of days, and then
once we decided to go, he had the hardware working in a day or so. It's in
Verilog, so perfect for an FPGA devel board; I think it's in his Github
repository:
https://github.com/dabridgham/QSIC
If you go this route, I have that config-file driven uassembler written in
portable C (compiles on 3 different systems that I know of) which uses only
standard I/O library which you can use for the ucode; it should handle most
any uengine design, unless it has something really wierd.

That's for the -11/40 - very different machine, one couldn't use the same
technique on the /45; the /40 is prepared to accept additional ucode on
additional CPU boards, that's how the EIA works:
http://gunkies.org/wiki/KE11-E_Extended_Instruction_Set
And it's custom boards, the design for which is no longer extant (pity, as
I'd love to play with one myself).
Finally, I have this vague memory that they had to put a few minor mods on
some of the existing CPU boards (details also lost), although my memory may
be misleading me on that.

> From: Kyle Owen
> So the same technique would work on the 11/35, then?
Yes, the /35 and /40 are completely identical, except for the number
painted on the inlay on the front console.
(Well, the /35 was often sold in a BA11-K box, and the /40 in a BA11-F, but
that's just physical configuration, and is just a 'usually' - there are
/35's in BA11-F's [for sure], and probably /40's in BA11-K's.)

I?m looking for a circa 1974 copy of RSX-11D distribution and the COBOL compiler that was shipped as an add-on product.
I?ve looked through trailing-edge but maybe I am missing the obvious, anyone have any ideas or has a copy?
thanks
Not affiliated with seller, etc.
Intel 386 CPU. Remember when we bought them and thought they were so fast!
Well..maybe someone has that obscure application that needs them.

Hello folks,
This weekend I picked up a VT52 DECscope terminal from a fellow collector. It's in fantastic shape, apart from being a little dirty and missing the number "6" keycap from the number pad.
This is a real long shot, but if you have a permanently broken VT52 terminal you're keeping for parts, could you please let me know? I'd like to buy a "6" key and make this one complete.

So I have discovered that the manual and prints for the MM11-F core memory are
not online; it turns out I have a manual/prints set, and at some point will
get them scanned and over to Al.
My question is: is there anyone who has an immediate need for these things?
If so, I will make the scan higher priority, otherwise it'll be a round tuit
number.

[apologies for lack of context, been away from cctalk a long time and insufficient recall of how this cctalk thing works... yet somehow still remember IAS on an 11/70 from the 1980s]
Pick an RSX layered product and lots of fundamental stuff would probably be compatible between 11M, 11D, and IAS (and/or 11M+). Find the RSX version and see if IAS is mentioned as supported in the SPD or other documentation. It often was, and even if it wasn't, lots of non-priv stuff would just work.
More IAS background from someone (not me) who was there in the IAS development team in DEC Reading:
https://www.john-a-harper.com/ias.html
"This page is dedicated to the best of the many PDP-11 operating systems - IAS
I couldn't find anything else on the Web about IAS? but it deserves better than to fall completely into obscurity.
DEC's approach to operating systems for the PDP-11 was anything but disciplined. New ones got invented every time some engineer or marketing person blinked. In the early days, there was a real-time kernel called RSX-11A, designed for memory-resident applications in what we now call embedded processors. Features got added to this rapidly - code bloat is nothing new. By the time it got to RSX-11D it had a complete disk-based file system, a program development environment, and support for every peripheral in the Small Computer Handbook (and there were plenty of them - peripherals on the PDP-11 obeyed the same strategic imperatives as operating systems - see above). At this time, a bright young engineer called Dave Cutler decided that enough was enough, and set out to create a small system that would do the same, which he called RSX-11M. We all know what happened to him - and he no longer even has the excuse of youthful excess.
