Beware of Chris W Tucker ( Low End Mac mailing list seller)

by aek＠bitsavers.org

Chris W Tucker jetrigger at gmail.com never shipped two powerbooks (about $500 worth) I'd complain on the LEM feedback list, but it doesn't work and they won't accept any comments on the main mailing list lemswap at googlegroups.com

Slightly OT: Sun Ultra 5 Keyboard

If no keyboard is connected the machine defaults to serial console on the first serial port. (IIRC this is the DB25 one.) 9600 8n1. Before investing money in a keyboard and mouse you should check if the machine lives at all via the serial console. -- tsch??, Jochen Homepage: http://www.unixag-kl.fh-kl.de/~jkunz/

RTEM might be something else than RTEM-11, which was a software product for RSX. Just google for RTEM-11, and you'll find some references for it. However, I wonder about RTEM for VAX. It's certainly possible, but I can't find any other reference to it, and DEC's old SPDs, especially those with software version compatiblity matrixes, are usually pretty good as a way of finding out what software existed. As for PDP-11 compatibility in VAXen, yes, the 86x0 machines have that. Those were the last, however. For all other VAXen running VMS, if you wanted to run RSX software, you needed a PDP-11 emulator product for VMS, which was available, in addition to the RSX additions for VMS, which was also a separate product. That thing was supported up until fairly recently, though. But again, that's for RSX stuff... Johnny

Moto 88k on ISA card (was Re: 68K ISA project)

by classiccmp＠crash.com

> Were there any ISA boards released with the Motorola 88000-series CPU on them? But of course! Opus Systems, like Definicon, put a couple of different CPUs on full-length ISA cards that would be added to or bundled with PCs to create a lower cost workstation in the latter half of the 80s. Opus delivered products using the Nat Semi 32000 family, later developed the Personal Mainframe Series 8000 using an 88k chipset, and eventually did it again with SPARC. We had one of these 88k boards in a Compaq DeskPro on a researcher's desk in 1991 and he was quite pleased with it. If one of these 32k or 88k systems/boards should need a new home, feel free to give me a shout. ;^) /Los links!!/ - All of the following shortened links go to Google Books.

ACE xx2247 key

by spedraja＠ono.com

Hello. I sent this request initially to PDP8-Lovers list, but I send the same request here in the confidence of some help. I am cleaning one PDP8E box with some boards inside. Previously to do some cleaning of the internal boards, I tried to fire up the computer yesterday. In appeareance nothing is wrong no strange smells, no burns, no clouds, no boom!, etc...) But... I don't have the front key :-) One ACE xx2247 is needed. I don't have one available, and is impossible for me to get one in my country (Spain). I would be grateful is someone could provide me one, or even a couple. Contact me off list if you want to discuss details. Regards Sergio

Can > anyone comment on these questions? As far as I know, RTEM-11 will not run under VMS. It was a product for RSX-11M (only). Long since retired now, and I don't have any details on it. However, I seem to remember that when you do an -11M SYSGEN, you still get a question for some RTEM-11 support to be included in the system. As expected, it will trap RT11 EMTs, but exactly what it will do for specific EMTs, and in which cases it might differ from RT11, I have no idea. It's probably also not compatible with any "recent" changes to RT11, just so that you know... Johnny

RTEM-11

by jhfinedp3k＠compsys.to

I have fixed some of the bugs in a program which runs under RT-11 (obviously using the PDP-11 instruction set - since actual DEC PDP-11 hardware can be replaced by either other compatible hardware on an emulator such as SIMH or E11). The bugs were causing problems when the program was run under VBGEXE, especially when the program was run as a system job. The requirements for the changes and additions to the RT-11 code have been determined. However, the same program is expected to run under RSTS/E (using SWITCH RT11), TSX-Plus (which is fully compatible) and RTEM-11. It is this last expectation for which I have been unable to find any documentation, let alone any ability to test the program. Does anyone who is reading this know where there might be documentation available concerning how RTEM-11 handles RT-11 EMT requests? In addition, does anyone know of any systems currently running which support RTEM-11 features which allow RT-11 programs to run in that environment? My assumption is that VMS on a VAX supported RTEM-11 at some point, but perhaps (if I am correct) the RTEM-11 support was not continued with more recent versions of VMS on the VAX and most definitely VMS on the Alpha. Can anyone comment on these questions? Jerome Fine
