I have a number of M105 and M7821 boards available. $15/ea (ie $30 for the pair) + shipping. If anyone's interested. -- TTFN - Guy

sexy PDP-11/44 panel (was: Re: Original 11/74 front panel)

by henk.gooijen＠oce.com

That would certainly be a good approach, but also definitely not the easiest. Writing the required code in "pseudo language", then code in 8085 assembler and burn in EPROM is just one step, but you need some 50-60 I/O lines to control the lights and read the switches. That's additional hardware ... but I have not [yet] looked at the diagram of the 11/70 console. Perhaps you can modify it slightly and add multiplexers to get the I/O line count down. Also, but this depends a bit on the console you want to hang on the /44, you cannot simply connect the (data) LEDs to that UNIBUS DATA lines, because depending the knobs (on a /45 or /70) you must display something different. OTOH, a good question would be "to what extend must the attached panel be operational? Fully or partially?" If you select the /35 (aka /40) or even easier the /20 or /10 console you can safe yourself a lot of work. Or go one step further and add the /34 or /60 console on the /44. Not *that*, I would certainly *not* start on. Indeed, not going to attempt any of this, not even in the far future! But I would love to read the workz of others in this area! - Henk. ________________________________ Van: cctalk-bounces at classiccmp.org namens Tony Duell Verzonden: ma 13-02-2006 16:52 Aan: cctalk at classiccmp.org Onderwerp: Re: sexy PDP-11/44 panel (was: Re: Original 11/74 front panel) > > Without thinking much about it, I'd say that mounting any > real blinkenlight console on a 11/44 is *not* trivial! > Of course, grabbing UNIBUS address- and data-lines and wiring > that to the lights is trivial, but to get all panel functions > (LOAD ADDR, DEP, EXAM, etc). working on an 11/44 is more work. I wondered about wiring the panel to the 8085 console processor, and re-writing that firmware to take commands from the panel switches, not >from the serial port. But it's not something I am likely to work on any time soon... -tony This message and attachment(s) are intended solely for the use of the addressee and may contain information that is privileged, confidential or otherwise exempt from disclosure under applicable law.

Tandy Xenix disk images

I have created new disks. I was interpreting the DS/SS index hole incorrectly on the first try. Still trying to create ImageDisk images also. Doing these next, probably by Wednesday. Kelly

sexy PDP-11/44 panel (was: Re: Original 11/74 front panel)

by henk.gooijen＠oce.com

Very true, Pierre. It is a matter willingness to travel several hundreds of kilometers just to get something, but in the first instance it's of course a matter of luck. The years that the real old stuff was thrown out are gone. An 11/34 can be found with some patience, but the machines with many lights and switches are indeed becoming a "rare find". Edward and I travelled from The Netherlands to Italy to get two (!) 11/70's ... already some four years ago! We did not pay $1000 for the machines, but we both paid $400 for the truck rental. Almost the same, as in the end, your wallet is just as empty :-( - Henk. ________________________________ Van: cctalk-bounces at classiccmp.org namens Pierre Gebhardt Verzonden: ma 13-02-2006 18:26 Aan: General Discussion: On-Topic and Off-Topic Posts Onderwerp: Re: sexy PDP-11/44 panel (was: Re: Original 11/74 front panel) > I guess there are more people on the list who have a boring > PDP-11/44 with a dull panel, that would like to make the /44 > more sexy with an 'appropriate' panel. The "upgrade" is, > of course, done in such a way that it can be undone ... > I (we) do not have a /74 panel :-( Well Henk, at least, you HAVE PDPs with a "lights and switches" console. Please think of those (I'm part of them!) who are eager to get one. 11/24 or 11/73s are nice, but unfortunately not the same. Today, it's almost impossible to get one...if you don't consider the possibility of buying one for a 1000$. THAT'S definitely the case for students like me. ... 11/74s are really cool!

Add-on boards for VT-100 backplane

by Useddec＠aol.com

The VT103 had a Q-bus backplane. The VT105 and VT125, and several compatible, were all add ons. The VT101, 02, 31, and 32 were just different boards in the same unit. There was also the PDT11/130, and a few others. Paul
