OT? Scrapping electrionics (was Lot of PDP-11/84 on ebay in Boston)

The older boards (80's or earlier) should be worth much >more. I hate the thought of scrapping, but my basement was full of old systems that I couldn't give away. So I've been trying to find an inexpensive means of doing so. Either New Jersey is special or I'm asking the wrong people. Most places CHARGE to take populated circut boards here. These are PII and PIII motherboards without CPU. Some even require special universal waste forms, fees and tracking be used. The highest quote I've gotten is paying $0.70 per pound (down 0.05). The lowest that has quoted so far charges $5.00 per pound for motherboards and $10 per monitor. I'd love to find someone paying $1.50 per pound. I've tried all my google-fu and can't find anyone. Here is the site with the highest rate so far: www.rockawayrecycling.com Kelly

The default background for xdm should be settable in its resources via its app-defaults file. But...does DECwindows use something other than ordinary xdm by default? Do SHOW PROCESS and find out; I don't recall. > There is also an error in the log above reading a font, is the font supposed > to be on the X server or downloaded from the client? Standard X fonts reside on the server. I say "standard X fonts" because there's a trend in current X development to do font handling on the client side. That won't be happening here, though. > After I got the colour logo, I then logged in and got some other errors in > the log too: > > 3 > OpenFont: decw$cursor > 3 < C:\Program > Files\Hummingbird\Connectivity\11.00\Exceed\Font\misc\deccurs.wff > > Warning: Access refused on ChangeHosts request based on security setting in > Xconfig. > > Warning: Access refused on ChangeHosts request based on security setting in > Xconfig. > Connection read error at 144525 > > Not sure what ChangeHosts means and what the implications are. I'm not sure what that is either; I've never seen a message like that. I'm betting it's Exceed-specific. > Anyway I have some colour now and it looks more like I would like it.

M68000 ASM to machine code table

by aliensrcooluk＠yahoo.co.uk

Hi, I am attempting to create an assembler to machine code table, something along the lines of: move.l a3,$12345678 -> $23 $CB $12 $34 $56 $78 Has anyone already done this? I don't mind whether the machine code is referenced in hexadecimal, octal or binary. I just need this to help me out with something - I have tried some disassemblers, but since they often (always?) turn data/text into ASM instructions and create false jumps etc. I am attempting to do it by hand. But before I can do that, I of course need the machine code references to start with! Failing that I will just have to create it myself - I have started, but having realised the number of possibilities for just the move.l instruction I feel that this could be another long project.... Regards, Andrew B aliensrcooluk at yahoo.co.uk

I'm sorry for how terrible this will sound, but I don't know how else to say it...Where X is concerned, I know my stuff as well, and it really doesn't sound like your friend does. I mean no disrespect either to you or to him by that statement. I have an X11 window directly to the right of the window I'm typing this message in, it's showing colors, and it's being displayed here from another system on the network. I run like this all day, every day. I'm not running Exceed, but a different (current technology) X server, but the concepts and protocol are the same. > I suspect the SHM thing could be why it works on a real workstation, Nope. SHM (more properly "MIT-SHM") is only used for images. (XImage objects in particular, and sometimes pixmaps) Background colors or drawn objects don't use SHM. It's used where image transfer speed is important, like video and animations. > or perhaps it is some DEC-specific thing? Nope. I've run color X terminals (which is essentially what you're doing with Exceed) from DEC X implementations, and they work fine. This is where it call came from, after all: DEC was a member of MIT's Project Athena, where X originated. I've never seen anything DEC specific there with the exception of DDX (device-dependent) code and their window manager. The former is almost by definition vendor-specific, and the latter is too, but perhaps less so depending on your point of view. Some background: An X client program (which includes your login window, it's an X client too) initiates a connection to the X server and does a few things, including optionally making a call to XGetVisualInfo() to get the list of "visuals" that the server supports. A "visual" is basically a target display type that specifies the color depth of the display, and might be something like "monochrome", "8-bit greyscale", "8-bit pseudocolor", "true color", etc. Most X servers support many different visuals simultaneously. The X client then selects the visual it wants to use. (a note for the pedantic: yes, I've skipped many Xlib calls and details here for brevity) It's possible that Exceed does not have any color visuals that the login window X client supports or wants to select. Note that I typed "OPTIONALLY makes a call to XGetVisualInfo()" above. It's possible for an X client to just use the "default" visual, and that is server-specific, and usually configurable. On most X servers, the default visual (actually visual "class") is set on the command line when the server is started. I have no idea of how to set the default visual for Exceed. We can drill down a bit further if you'll log into the machine via Exceed, and run "xdpyinfo" and look at the output. Pay attention to the visual names and IDs that it reports as being available. Are there any color visuals present? Also, look at the default visual ID for the first "screen" entry. See if that visual ID is that of a color visual. If it isn't, but if there are in fact color visuals present, it's possible that the login window X client was written to only use the default visual, which may not be a color visual under Exceed, but might be a color visual on the workstation. It's also possible that the login window X client is configurable via its app-defaults file. We can check on that if you strike out with the visuals described above. -Dave -- Dave McGuire Port Charlotte, FL

ANN: liblpfk (IBM LPFK driver library), tumble-0.33-philpem1

by philpem＠philpem.me.uk

Hi guys, A few of you might remember the IBM LPFK bulk-order a couple of years back, and the ensuing chaos of figuring out the control protocol (which was eventually resolved when Michael Brutman found some old IBM protocol docs which covered the LPFK). I figure I've been sitting on the code for long enough: it's time to make a proper release! Anyone who wants to have a play with this is welcome to do so: the code is on my website, under "Code :: liblpfk", or if you'd prefer a direct link: http://www.philpem.me.uk/code/liblpfk/ I've also uploaded my fork of Eric Smith's "tumble" utility, a TIFF-to-PDF converter. I found a couple of bugs (which haven't been fixed seven months later) and figured it was a shame not to share the patches. After all, it is open-source :) URL for that is http://www.philpem.me.uk/code/ -- click "Tumble". At some point I'll give this a separate page instead of just linking to the version-control repository, and may well document the control file format (which IIRC isn't documented at the moment). Somewhat offtopic, but I've also released a driver for one of the Brother P-touch label printers. I needed labels for my spare parts boxes and really didn't feel like making them with a Dymo gun when I had a perfectly good stock database (which is next on the 'stuff to release' list) which I could use as a data source for said labels. Work smarter not harder and all that ;) These were written for Linux, but should work decently well on BSD too. Forget running them on Windows unless you want to port the serial-line (liblpfk) and/or usb-lp (libptouch) stuff across... I didn't (this be a Linux-only ship, yarrr!) Comments, criticism and so on should be sent to the address below. Sensible patches are, as always, gratefully received 8^) FYI: I'm working on getting a copyright release from university for the DiscFerret software. At the moment half the Department of Computer Science is on holiday so this is proving somewhat difficult... PCB design is still ongoing, though a lack of funds means it might be a while before I get prototype PCBs made. I'm hoping to release the firmware, microcode and decoder engine under the GPL or LGPL, and the hardware access library will most likely be distributed under a "BSD-with-attribution" type license (I forget, is that 3-clause or 4-clause?). Either way, it'll be GPL-compatible (for obvious reasons!) and commercial-use-allowed. Thanks, -- Phil. philpem at philpem.me.uk http://www.philpem.me.uk/
