Bringing up the MIT-V6+ under an emulator (so they could be run) would be a _lot_ less work, since I'm already intimately familiar with it, and I already have vanilla V6 running under an emulator (which I could use to produce a MIT-V6+ kernel that would boot under the emulator - the existing kernel images wouldn't, they use disk controllers that the emulators don't support). > I'm still looking for (NCP) ARPAnet code for v6! That's there too - that's being discussed on the TUHS list. See the archives. Noel

Interested in just the BASIC, or in the whole package? For those who are interested in running any of this stuff on a UNIX of some sort (as opposed to, say, taking the BASIC source and editing it to run under some DEC OS, using the pre-existing MACRO-11 on such a system), there are dependency issues one is going to have to deal with. That's because the MACRO-11 is written in MACRO-11, and the BCPL compiler (which one needs to compiler the linker) is in BCPL. So before either one can be assembled/compiled... one needs a working assembler/compiler (as the case may be), along with a linker. Can you say 'dependency loop'...? :-) I _do_ have working binaries (I think) for the MACRO-11, BCPL compiler, and linker.. but they may or may not run under vanilla V6 (they ran on the much-modified MIT-V6+, which is kind of an early PWB with a lot of MIT additions). Let me try them and see if they run under vanilla V6 (which I have running under Ersatz-11), and if so, then I can hand out the whole package. That all will take a couple of days to deal with. Noel

Compaq 9000 Series Rack

by cctalk＠ibm51xx.net

Hello All, So maybe not quite classic but I believe in the vintage time frame - does anyone, ideally in the greater LA but even SoCal area, have a line on an Opal White 22U Compaq 9000 Series Rack? This is the half height rack not the full height 42U which seems to be everywhere (you can see pictures of a similar unit here: http://www.vcfed.org/forum/showthread.php?55953-Compaq-22U-Rack-9122). I don't have enough space for a full height one and the half height fits the bill nicely. TIA and sorry for interrupting the DEC talk! -Ali

RT-11 Basic source available

by jnc＠mercury.lcs.mit.edu

Hi, I don't know if this is of any use/interest at all, but I have retrieved an old/early copy of RT-11 Basic (V01-05 18-JUL-73, DEC-11-LBACA-A-LA1) modified to run under V6 Unix, if anyone has any use for such a thing. I also have a DEC MACRO-11 which runs under V6 Unix, which generates .rel files; there is a 'bind' (written in BCPL) which is a linker which reads .rel files. (There is a BCPL compiler, written in BCPL, to compile it.) Then there are two command 'relld' and 'ldrel' to convert back and forth from .rel to a.out. Noel

SONY NWS-1250 PSU

by plamenspam＠afterpeople.com

I recently obtained Sony portable model - NWS-1250 from Japan. There is a bottom label "AC 100V", however the PSU has 100-120V and 220-240V label. The exact PSU model is Sony 1-413-548-11. Is it safe to plug it in 220V AC or to wait the arrival of step-down transformer ? The other problem is that the disk has been wiped. Does anyone have NEWS-OS CISC version media ? Best regards, Plamen

What's the rarest or most unusual computer-related item do you own?

Doug! We would like a scan of your dad's certificate! We have an ongoing collection on this computer at SMECC 1955 Honeywell computer business was originated from the Datamatic Corporation, founded in Newton MA, as a joint-venture by Raytheon and Honeywell, to produce large-scale computer systems. Raytheon sells its 40% interest to Honeywell in 1957.. 1957 Installation of the first Datamatic D-1000 to Blue Cross/Blue Shield of Michigan. Honeywell Datamatic 1000 uses 3 inch wide tape we have a 3 inch very very heavy reel and the 30 something track tape drive head.... could this someday be the start of the ultimate DIY tape drive build and tape recover? see more on this computer here... and we have modules for this tube computer we need to photo and more stuff to scan and add. http://www.smecc.org/honeywell_datamatic_1000.htm In a message dated 1/29/2017 1:27:26 A.M.

Thanks Guy! Mystery solved! I will put this note in with the memory stick.. Ed# _www.smecc.org_ (http://www.smecc.org) In a message dated 1/28/2017 6:00:46 P.M. US Mountain Standard Time, ggs at shiresoft.com writes: At one time IBM was the largest manufacturer of memory and consumed *all* of it internally (e.g. for IBM products). At the time all of IBM?s ICs were in the ?aluminum? cans unless they needed more exotic cooling. In the PS/2 days, we ended up using some IBM produced memory because we could get a better internal transfer price than buying out in the market because the various IBM fabs had a bit of excess capacity and wanted it used.

by COURYHOUSE＠aol.com

The talk of PS2 memory brought something back to me I have in a drawer here... ps2 memory - with weird square silver IBM Circuit packaged memory on the stick. What is the story on this? was IBM making it's own memory chips or just repackaging them into their silver square packaging? Now I will have to dig these things out. Thank Ed# _www.smecc.org_ (http://www.smecc.org)

Looking to read past EOT on DDS/DLT/LTO

As it happens, they (partitions vs. set marks) are different concepts. A DDS-1, -2, -3, -4 can be either a single unpartitioned tape *or* it can have precisely/exactly/only two partitions. (I didn't check newer DDS standards) Completely separately from any discussion of partitions: a tape basically consists of entries of type "Data" (user data) and "Separator Marks". The standards (e.g., ECMA-139 / ECMA-150 / ECMA-170 for DDS-1, ECMA-198 for DDS-2, ECMA-236 for DDS-3, and ECMA-288 for DDS-4) specify: "In this ECMA Standard, there are two types of Separator Marks which are referred to as Separator 1 and Separator 2. Some other standards, e.g. those which define an interface between a tape drive and a host computer, use the terms "file mark" and "set mark" to denote Separator Marks. It is recommended that Separator 1 be equated to file mark and Separator 2 be equated to set mark. ("file mark", of course, is also referred to as an EOF (End Of File)) I knew DDS-* drives were insanely complicated, but after reading parts of the standards, I now realize I was grossly underestimating just how insanely complicated they are! SDLT-1 supports "set mark" (and they're called that, not "Separator Mark 2" :), but not partitions. DLT-1 and Ultrium-1 support neither "set mark" (nor multiple kinds of separators) nor partitions. Stan (ECMA = European Computer Manufacturers Association) ISO/IEC 17462 = ECMA-288
