Nowadays, with wikipedia and all, one would think that people would actually check things up... :-) See http://en.wikipedia.org/wiki/Sql, under the history section... I'd say "sequel" is almost more correct than "ess kyu ell". :-) But of course everyone is free to pronounce it any way they see fit.

I may be remembering what happens when one tries to install an auto-inject floppy drive into a later model Mac which expects a manual inject drive. In which case it has nothing to do with the cable, although I have seen both red and yellow striped. Anyway, I know I was building a system out of bits and pieces and saw that behaviour from the floppy, but maybe it was auto-inject in later model Mac rather than wrong cable. I hadn't started keeping a lab notebook yet, at the time. I know I've built floppy cables for PCI PowerMacs and manual inject floppies using standard ribbon cable and crimp on IDCs (connectors, is that redundant with IDC?). Jeff Walther

so wait, how much vacuum would destroy something? I have a few things sealed in Foodsaver bags, is this enough vaccum to do damage?

Good tip. Another is that SYSGEN under VMS can also do this. Check the HELP if you are curious. Yet another is FLOAT.CMD, which comes with the DECnet distribution of RSX.

A Mac > enthusiast may know more. I don't remember all the details. I do remember that there is a cable with a yellow stripe on pin 1 and another version of the cable with a red stripe. If you install the wrong cable (can't remember whether it's red for yellow or yellow for red) the eject motor does indeed run continuously. It doesn't seem to damage the drive; I never let it run more than a few seconds. So it's easy enough to identify and correct. Jeff Walther

OT? Tek 4014 emulator (tying Xterm to ttyS0)

by philpem＠philpem.me.uk

Hi guys, I'm building some hardware that spits out debug info on a regular basis, and I figured it'd be useful to have this data graphed on-screen. Making it keep track of the last "N" samples and draw them wouldn't be hard, except adding an LCD display is out of the question (takes up too many I/O pins). On the other hand, I have a perfectly good serial port which runs at a decent rate of speed (115200 baud), and Xterm can emulate a Tektronix 4014 vector terminal. Perfect... except I can't see an easy way to tie Xterm to a serial port instead of having it run an application. There's nothing in the manpage (admittedly I haven't read it all, just grepped it for a few obvious terms) and 'apropos' isn't finding anything useful. I've been told that tip(1) on BSD will do what I want, I just can't find anything similar on Linux... Thanks, -- Phil. philpem at philpem.me.uk http://www.philpem.me.uk/

Free empty TI 960B

by richardlynch4＠tx.rr.com

If anyone is interested in an empty TI 960B chassis for the cost of shipping, please contact me offlist. Includes only the frame, motherboard and power supply - no front panel or boards. Even so, it's still big and heavy so local pickup (near Dallas Texas) will save some money. Richard Lynch

wall of sgi photos

by legalize＠xmission.com

I finally got around to taking some photos of the warehouse where my collection is stored (along with my friend's arcade game collection and a computer recycling outfit). Most of my stuff isn't really in good "show" condition right now as I'm trying to organize my friend's arcade machines and my space is temporarily filled with some of his overflow stuff to make holes so I can move machines around. At any rate, you can get a good view of my Tektronix storage tube terminals and my wall of sgi. Also, there are some photos of the Eve cabinets for Jos Dreesen. Sorry, just one side of the exterior of the cabinets for now, board photos to come later when things aren't so cramped. <http://picasaweb.google.com/legalize.slc/Warehouse#> -- "The Direct3D Graphics Pipeline" -- DirectX 9 draft available for download <http://legalizeadulthood.wordpress.com/the-direct3d-graphics-pipeline/> Legalize Adulthood! <http://legalizeadulthood.wordpress.com>
