Canon BJ-250 problems

by aliensrcooluk＠yahoo.co.uk

I have been having problems with the printer named in the subject line. It was working fine the other day and stopped halfway through printing something. I changed the ink cartridge, but it still doesn't work. It just beeps a few times after being switched on, with the0green light flashing. Any ideas?

ancient marine electronics

by bthomas＠brothom.nl

I got this stuff at an auction for 12 euro. It's an Z80 based measuring device and a depth sounder transducer. You can see the pictures here: Although the Z80 based device is on-topic, I am particularly interrested to find out how to use the depth sounder. It has only 2 wires, so I assume it is some sort of element that is both an actuator and a sensor? Has anyone any info on this stuff? The transducer is a lowrance electronics TTH 1192-8.

Old C Code Headaches

by wlewisiii＠gmail.com

So in a fit of insanity, I have a VM running NetBSD 1.6.2 (the earliest I can get to run for me under Virtual Box) that I'm trying to build the old Franz Lisp (from the 4.2BSD days) on. There was a port done by Jeff Dalton back in 1994 to i386 NetBSD .9 so there is a working executable but to get the libraries up to date requires a build. That is exposing a bunch of early '80's code that isn't working too well. Stuff like: lispval Ndumplisp() { register struct exec *workp; register lispval argptr, temp; register char *fname; extern int reborn; struct exec work, old; extern int dmpmode,usehole; extern char etext[], *curhbeg; int descrip, des2, ax,mode; extern int holesize; char tbuf[BUFSIZ]; long count, lseek(); pageseql(); pagsiz = Igtpgsz(); pagrnd = pagsiz - 1; #ifdef __NetBSD__ { /* Round the break up to a multiple of a page size */ int excess; excess = (long)sbrk(0) & pagrnd; if (excess > 0) sbrk(pagsiz - excess); } #endif /* dump mode is kept in decimal (which looks like octal in dmpmode) and is changeable via (sstatus dumpmode n) where n is 413 or 410 base 10 */ if(dmpmode == 413) mode = 0413; else if(dmpmode == 407) mode = 0407; else mode = 0410; workp = &work; workp->a_magic = mode; (and so on for much longer) Those structures aren't right & the workp-> pointers all give major complaints in GCC (dereferencing pointer to incomplete type) and it bombs out. My C is even rustier than I thought so it's driving me nuts trying to remember what's wrong. What I'm hoping is that someone can point me at is a good online reference or tool to old K&R C that I can hopefully restore my memories of what is going wrong in this and the other issues I'm sure will pop up.

Perhaps deep enough to be Multibus II or VXI, but the interface logic doesn't look right. In all likelihood, though, it's their own thing. I've certainly made the mistake of picking up some odd bit thinking it might be VME only to find it was custom. DIN 41612 connectors got used in all sorts of things, particularly where reliability was a concern. KJ

If that's a direct response, then all I can do is avoid eye contact, back slowly away and repeat "there's still no one, before or after support was dropped, for all the years that anyone could, who's taken on the job of keeping it in the tree, and that's the only reason it doesn't exist". I'm sure you'll find reason to dispute that, but I don't see taking the time to puzzle out the entrails of your inevitable reply for actual meaning. > > P.S. - While I get it's your standard dismissive > > line, > > It certainly isn't; I'd not treat you in that manner.

It is hard to keep track, but this is pretty clearly the one for people who you think don't understand embedded systems.

And, admittedly, I've not trotted out my experience to bludgeon anyone who disagrees with me. So, how could you possibly not lecture me like a schoolboy. So...point taken. KJ

FMS computer

by bthomas＠brothom.nl

Hi, http://www.flickr.com/photos/bertsfotos/8959539296/ This is an "FMS-5/88" computer. It looks like a VME-bus type of card, but is completely Intel based with an 8088 and 8087. Does anyone know whether FMS is a similar to VME-bus? I had never heard of FMS before. It think its brand is "grossenbacher elektronik", a Swiss company I think. Regards, Bert

[cctalk] Old UNIX Systems

by barythrin＠gmail.com

I haven't been in the semiconducter industry since the late 90s, nor was I involved with any design education but from what I saw the problems were size as you said and replacing equipment that can work on that new size transistor. Heat generated by the smaller footprint creates new problems. The metals used also can only be reliable to a certain extent with size, price, and heat. To be honest I'm pretty happy not needing to think on that scale. Last thing I read about was some sort of stacked design (although that was already the case so I'm not really sure the new aspect other than adding insulation in between layers which is also old technology). The comment on projecting displays, microsoft will likely start to publically support the already working xbox gesture thing (can't remember product name this minute) with windows. Its already had a driver created I think unofficially but I'm sure if they port it to pc it'll boost sales for both systems.
