There's a few IBM 3164 terminals down at Purdue University Salvage and Surplus that are about to be thrown out. If anyone wants one, let me know, and I'll ship them for $5 + packing stuff + shipping. Respond soon, they'll probably be gone in a day or two. Pat -- "The Microsoft/IBM FORTRAN was adequate for teaching FORTRAN 77. But the performance was AMAZING!

Hi I see the rest seem to have a similar opinion of this manufactures drives. I got mine from experience. Dwight >From: "Jim Arnott" <jrasite(a)eoni.com> > >High explosives work well too.

What symptoms are exhibited by >an improperly terminated drive? Hi This can vary, from not working at all to the occational bad read or bad write of a sector. Some times it shows up as a data dependent problem. The disk formats fine but can't write all 1's or all 0's. In both of my cases, it would occationally damaged data on a write that would show up as a non-recoverable CRC error. Although it is recommended that the termination be on the last drive on the cable. I've never found it an issue when the two end drives cable connectors are only 2 to 3 inches apart. I have been known to put the termination, where ever it is handy, while trouble shooting( such as swapping drive ). I also alway tape the terminator to the drive that I remove it from. I don't know if I or someone in the future will need that terminator. If it is right there, I know it is the right one. Dwight

Swapping boards on ST225 drives / Philips P3800 help

I've seen it twice now that I have a machine that has a flaky disk and I open it up and see a terminator on both drives. Removing one brings back normal operation. One of the machines was a KayPro and the other was my Olivetti M20. I suspect that these were that way from the beginning since both normally ship as dual drive machines.

Origin of "half-inched" - OT

by xds_sigma7＠hotmail.com

Honestly, I would've expected you Brits to say "nicked", but yeah.. FYI further synonyms (american) would be jacked, ganked, swiped, etc. Will J _________________________________________________________________ Choose an Internet access plan right for you -- try MSN! http://resourcecenter.msn.com/access/plans/default.asp
