Looking for a VT52 keycap

by web＠loomcom.com

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. -Seth -- Seth Morabito web at loomcom.com

MM11-F manual/drawings

by jnc＠mercury.lcs.mit.edu

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. Noel

DEC RSX-11D and its COBOL compiler?

by johnwallace4＠yahoo.co.uk

[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. (continues...)" Hth.

Eudora email client source code released

by len＠shustek.com

For the last five years I've been working with Qualcomm and others to allow the Computer History Museum to release the source code of what was, in my opinion, the finest email client ever written: Eudora. It's finally done! http://www.computerhistory.org/atchm/the-eudora-email-client-source-code/

Linux Journal - the early years

by decguy＠songdog.eskimo.com

Is Linux "classic" enough? If you think not, please ignore this email I started with Linux kernel version 0.12 (not a typo), which I believe was the first version that was self-hosting. I subscribed to Linux Journal from its beginning. Is there any collector value or interest in old issues of Linux Journal? I have a continuous run for "several" years, beginning with the very first issue. Anyone interested? As many as you want could be yours for the cost of shipping (USPS Media Mail).

IBM 5140 - schematics?

by anders.k.nelson＠gmail.com

Hey all, I have an IBM 5140 portable with a printer but I'd really like to use it as a terminal among other things. Any chance there's documentation available for that Centronics connector or another internal header with RS232 or whatever? =] -- -- Anders Nelson +1 (517) 775-6129 www.erogear.com

Weird Lear-Siegler ADM-3A board

> From: Eric Smith > The NS455 has firmware in masked ROM ... The NS405 has the masked ROM > disabled Ah, thanks muchly! Do you know of _any_ documentation extant for the 455? I couldn't find anything.. > I've been searching for the NS405 manual (not the datasheet) for a very > long time. The data sheet seems pretty complete - are you sure there ever was a manual? Noel

Next 'stack' of computers to go, IBM p7's - not classics this time

by pete＠petelancashire.com

This time not so 'classic' My last job was maintaining IBM p7's and eventually p8's. One thing I started was putting together a home setup. But like all the other projects the gear has become redundant to me. The 'stack' consists of 2 each IBM p720's, a CR6 HMC, and a KVM drawer. The p720 do NOT have any hard drives or carriers, but both are available via Ebay. The carrier was used in more than one model, and in the past I've bought carriers with small disks for < $20 each, then found larger disks of various brands. And the rails are missing from the p720's. Google "ibm p720" I can't remember how much RAM, number of CPUs etc but one p720 was 'loaded'. If interested let me know and If anyone knows a good AIX list please let me know I'll try to get a few photo's this weekend. The 'stack' is located in Portland, Oregon. NO PACKING OR SHIPPING, must be local pickup. -pete

Weird Lear-Siegler ADM-3A board

by jnc＠mercury.lcs.mit.edu

> From: Jon Elson > Steve Ciarcia ... made a board using the NS405 called the Term-Mite. I decided I'd do an article about the Term-Mite for the CHWiki; I found Ciarcia's long article about the Term-Mite (in his book, which Google books has); it talks throughout the article about the NS455 - but it also says "[t]he Term-Mite actually uses a NS405 chip which is a specialized version of the generic NS455". So I went to look up the 405 and 455, to see what the difference was between the 405 and the 455. I found a data sheet for a 405, but not one for the 455. Does anyone know where I can find info about the 455 (or, better, yet, know what the difference is between the two - that would save me some leg-work). Thanks (I hope :-)! Noel
