PDP-11/53 jumper doc found

by engdahl＠cle.ab.com

I guess there must have been only one copy of the 11/53 CPU board manual left in the world, and Giorgio Ungarelli had it in Switzerland. He sent me a copy, and I will eventually get this information up on my web site. It is a supplement to the MicroPDP-11/73 manual. It documents the baud rate, boot, and halt option jumpers, etc. for the older version of the KDJ11-DA, the one with only .5 meg of RAM on board, and the CPU in the center. I've got one of these boards, and a couple of the newer ones (KDJ11-SD). I'm sure that once we know what the jumpers do, we can figure out where they got moved on the newer boards. I think the reason the board won't boot when you don't have a front panel is that the boot option inputs float to "15", which is "manufaturing test loop". -- Jonathan Engdahl Rockwell Automation Principal Research Engineer 24800 Tungsten Road Advanced Technology Euclid, OH 44117 USA Euclid Labs http://users.safeaccess.com/engdahl

adding MSCP driver to 2.9BSD

by engdahl＠cle.ab.com

I took the MSCP disk driver (the ra driver) from the PRO-350 version of 2.9BSD on the PUPS archive, and added it to the regular 2.9 distribution. The new UNIX builds and runs. I created nodes in /dev, and added a line to /etc/dtab, but the driver doesn't seem to work. I have figured out that the autoconfig will not work with this driver. It reports "No autoconfig routines". Evidently, probe is not implemented in either the 2.9 or 2.11 version of the MSCP driver. So, how to I get UNIX to "attach" the ra driver? This is the first time I've tried doing a UNIX sysgen, so extra explanations might be required. The only documentation I have is what I downloaded along with the distribution. -- Jonathan Engdahl Rockwell Automation Principal Research Engineer 24800 Tungsten Road Advanced Technology Euclid, OH 44117 USA Euclid Labs http://users.safeaccess.com/engdahl

X-10 (was Re: controlling power)

Costly? A 300W dimmer module costs like nine bucks. When I add up the price of the components required to duplicate that, I have trouble figuring out where they're making a profit. They're all PIC-based, by the way...the modern dimmer modules contain 12c508 chips. > It would be an interesting job, actually, though the MCU would be largely > wasted. It's smaller than an equivalent set of CMOS logic, though. Well, the 12c508 is a *tiny* processor with a *tiny* control store... -Dave McGuire

Xerox 820

by r_beaudry＠hotmail.com

Hello all, Recently I acquired a Xerox 820, but as a single board, w/ power supply. I also received many docs (including a tech manual with Monitor listings and schematics). I know originally these were "all-in-one" computers, but many appear at ham fests in exactly the same shape as mine -- as a single board computer. Of course, hooking a terminal up to it produces nothing (even testing at different baud rates/parity/stop bits, etc), so I'm wondering: - Are there any modifications (ROM or jumpers) to "convert" this to use the serial port for a console, rather than the keyboard and video display? I couldn't find anything in my docs, but of course, I have not read them in depth yet. In return, I could offer copies of the docs, or thanks to 22NICE and my Compaticard (thanks Don!), copies of the files on the diskettes (CP/M, "Word Processor", "Diagnostics", "Training Files" and "Program Files"), or images of the disks (assuming Teledisk could do it -- I haven't tried that yet). The disks are 5.25", SSSD Thanks! Rich B.
