Help wanted with an Open VMS installation

by r.lasbury＠ntlworld.com

The show device command displays the ethernet connection followed by the CDROM as.. BOOTDEV=DKA500 ADDR=A/5/0 DEVTYPE=RODISK NUMBYTES=681.88MB RM/FX=RM WP=WP DEVNAM=CD-ROM REV=1.1C and it shows the hard disk as... BOOTDEV=DKA100 ADDR=A/1/0 DEVTYPE=DISK NUMBYTES=1.00GB RM/FX=Fx WP= DEVNAM=RZ57 REV=5000 I have actually tried 5 different hard disks: 3 seagate models and 2 original DEC RZ57 drives, but they all end with the same error message while installing!!! I have proved the 3 seagate disks on a scsi card on a PC and the 2 DEC drives work OK on a DEC 5000 machine booting up a copy of Ultrix, so I am pretty sure the problem is not actually with the disk drives. _____ << ella for Spam Control >> has removed 1854 Spam messages and set aside 242 Newsletters for me You can use it too - and it's FREE! www.ellaforspam.com

M7891-DC 2a fuse on +12? fixed!

I think I'll replace it with a nice axial lead tantalum. What you described is the classic symptom of an aged electrolytic that needs reformed. In an electrolytic capacitor, the aluminium foil forms one electrode (the anode), the electrolyte (gel) is the other (cathode), and the oxide layer on the foil is the dielectric (insulator). Unless the capacitor is charged, the oxide dissolves into the electrolyte over time, and no longer insulates. The cure is to pass a small current to reform the oxide layer, and gradually build this up until the capacitor can withstand its normal working voltage without much leakage current. Cylindrical caps in a metal can are more commonly aluminium rather than tantalum; tantalum caps are more commonly made as beads of sintered tantalum. The principle is the same, though: large surface area in a small space, with a metal anode, oxide layer as dielectric, and electrolyte as cathode. -- Pete Peter Turnbull Network Manager University of York

Restoring old floppies to usable state

If you have such with the correct >drive type then this program will exhaustively test and repair the surface >of any drive you care to test. I have a newer version of spinrite, and am VERY VERY VERY disappointed in it. I used it to check some hard disks that I thought were bad, it told me I was right, and I had it map out the bad sectors. The disks still failed to format. Others that is has fixed (and enabled them to format) failed shortly after with bad sectors. And of course, SpinRite only seems to do something if the drive itself is already accessible to DOS. If the drive isn't coming up (from as little as a non DOS compliant partition such as a Linux partition), then SpinRite will claim it can't read the drive at all. So basically, I've found that it doesn't seem to do much beyond that of Scandisk. VERY disappointing indeed considering GRC's reputation. -chris <http://www.mythtech.net>

This just in - Commodore B128 low profile computer (NOT 128D)

by chrisc＠addpower.com

The computer itself is kinda nice. It had a MOS 6509 processor in it, which was the beginnings of Commodore's memory management experiments. Some models also had the same video and sound chips as the Commodore 64. I'd really like one of these myself. :) steven <tosteve(a)yahoo.com> To: cctalk(a)classiccmp.org Sent by: cc: cctech-bounces@clas Subject: This just in - Commodore B128 low profile computer (NOT siccmp.org 128D) 02/05/2004 01:35 AM Please respond to "General Discussion: On-Topic Posts Only" Don't know much about it yet, but it sure is pretty! Seems to work fine. It came out the same time as the C-64, supposed to replace the PET and be their business computer, but didn't sell well, I guess. __________________________________ Do you Yahoo!?

RX8E printset?

by aek＠spies.com

"Diagrams for an Implementation on a TC08 Backplance" I guess TC08s are common enough in Europe that you can strip 'em to build floppy controllers.

Help wanted with an Open VMS installation

by r.lasbury＠ntlworld.com

Yes I am trying to use the hobbyist version of 7.3-1 however I obtained that version after I failed to get 6.2 to boot with exactly the same error. I thought maybe the later version would work !!!

Forced eBay ID Change?

by healyzh＠aracnet.com

Anyone else have their eBay ID forcefully changed recently? I've had an account for over 6 years and I predate the rules against using an email address. Looks like the b******* have decided to forcefully change all of us using email addresses for our ID's so as to better control the flow of information to us. Zane -- -- | Zane H.
