Can anyone help? There is a program "md5sum" that comes with GNU textutils. It will run on most Unix or Unix-like systems. I suspect that with a fair amount of effort it could be made to run on RT11, compiled with DECUS C, but I haven't really looked at that.. When you run mda5sum on a file it produces a 32-hex-digit "message digest". This should match the one that you downloaded from the original source. carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu

I happen to know (from the guy who > runs the place) that the local scrapyard is overrun with these ;) Just remember that all of the NeXT printers are getting on in age, and most of them have one or more of the fatal symptoms: Input roller has dried out so paper doesn't go in. Output gear has stripped so paper doesn't come out. There are other interesting problems that some printers have, such as the "door open" sensing switch insisting that the door is not closed. I don't know how many printers you would have to merge to get one that worked. Randy Rencsok's web site has lots of good documentation on disassembling NeXT printers. < http://www.channelu.com/NeXT/Black > carl -- carl lowenstein marine physical lab u.c. san diego clowenstein(a)ucsd.edu

PRO/Venix

by mbg＠TheWorld.com

In case anyone is interested, I was organizing some of my collection today and came across a set of Pro/Venix documentation in original DEC/Professional boxes and the V2.0 release of Pro/Venix (with the developers toolkit). I'm hoping the disks (RX50s) are still readable... If they are, I'll try to make image copies and get them to the PUPS archive... any place else I should consider?

AIM-65 displays

I scanned the pages directly to PDF (using Acrobar Writer) but I never got around to taking those scans and OCRing them to a text file (it was on the RSN list).

NeXT (Almost-up-and-running-now) Laser Printer

CX and SX engines sometimes have problems with crap collecting on the corona wires...especially the transfer corona underneath the paper path. Look for a trough about 0.5" wide with a hair-thin wire running through the middle of it, possibly shielded with a sparse wrapping of a plastic thread that looks like fishing line. Clean this VERY carefully by rubbing an alcohol-saturated cotton swap back and forth over it. That might help a bit. If not, it may be the drum precharge corona wire, which is inside the toner cartridge. There should be a little green plastic tool with a strangely-shaped felt tip stuck into a clip inside the printer. Stick this into the transfer corona wire access slot on the toner cartridge and run it back and forth. It's self-aligning due to the shape of the green plastic tool and grooves in the toner cartridge...there's only one place and direction in which it'll fit correctly. (sorry for the lack of detail here, this is difficult to describe textually) Give that a shot and see how things clean up. If that doesn't help, contact me and I'll see if I can dig up anything else from my dusty memories Canon CX and SX print engine repair training back in 1987. -Dave -- Dave McGuire "Mmmm. Big."
