They dropped the product and are no longer supporting or developing it. Too bad; it was helpful to have LAT to access LAT-based terminal servers. It doesn't seem to work with Win2K/XP. -- Eric Dittman dittman(a)dittman.net Check out the DEC Enthusiasts Club at http://www.dittman.net/

I actually had a track bug through there a few years ago... Megan

Rich, Check the website www.aecsales.com, They have the exact parts you need by the original manufacturer. When at the parts search page be sure to check the box for "restrict search to items with exact prefix". They have been very helpful finding obsolete parts for me. Don

Park heads when moving Kaypro 10?

by Robert_Feldman＠jdedwards.com

I seem to remember that self-parking heads generally were not available on the 10MB drives of Kaypro 10 vintage, so I did a little Googling and came up with the following (http://www.atarimagazines.com/creative/v9n12/8_The_Kaypro_10_more_than_.php ) from CREATIVE COMPUTING VOL. 9, NO. 12 / DECEMBER 1983: "A very important command is included in the Kaypro 10 system software. SAFETY moves the read/write heads on the hard disk to the safe landing zone on the disk. This must be done before turning the power off or the surface of the hard disk may be damaged. The SAFETY command is invoked from the command mode in CP/M."

IIRC, it is built into the operating system and when the HD LED goes out, the heads have been parked. - don > TIA -- > > Glen > 0/0

PDP-8/L troubleshooting (was Re: New acquisition, and question)

by mbg＠TheWorld.com

Okay, I've seen a picture of a PDP-8/L and the switches are correct. But someone went and replaced the front panel on it so it is dark lettering on a white background, with no company logo... Darn... Megan

Unfortunately, I never had access to DECnet/Ultrix... that was done in a different group. I don't think it was ever updated for later versions of Ultrix. It may still just run, though. I think the last version of it was V4.2. I'm not sure what the legal issues are about Lat, though... I think it is owned (or is it only marketed) by Meridian, ltd.
