>/U (do a REAL format) is faster for you than >/Q (DON'T do a real format, just write an empty directory) ?? > >Would you care to post some measured times for how much faster it is? Speed will be HIGHLY dependant on what size disk it is. A 360k disk formats with /u fairly fast, and although it is STILL quicker to do /q, it isn't a huge difference... however, when doing a 1.4 disk, it cam be the difference between over a minute and under 10 seconds. /q is basically the same as doing "del *.*", it doesn't reformat the disk at all, it just rewrites the FAT so the disk thinks it is blank, the fastest way to clear a disk is "format a: /q /u"... UNLESS there are only a few items on it, then del *.* might edge it out Also, with all this /u business... be careful when doing that on 5.25" disks in a high density drive. If you put a DD disk in, and do format /u, it will NOT warn you that it is going to attempt to format a DD disk as HD. In MS DOS, when you format on a HD 5.25 drive, it automatically tries to format HD... you need to specify the format size (or use /4) to format 360k... leaving off the /u will warn you that the format is different then what you are about to try. Unfortuantly, leaving off the /u ALSO fails to remap bad sectors, AND saves the unformat info adding a few more seconds onto the disk format. None of this warning business applies to 3.5" drives, they will detect the HD vs DD disk, and format correctly... so with those it is safe to always use /u if you want to. -chris <http://www.mythtech.net>

Odd VT100 question

by healyzh＠aracnet.com

OK, I'm thinking of doing a wierd mod on a VT100, just how much room is inside one of them? I need room for a 7 1/2" x 9" x 2 1/2" board (the 2 1/2" is thanks to the heatsink and RAM), and would also like to be able to fit in a smallish 250W PS (3 1/2" x 5 1/2" x 6"), and a 3 1/2" HD. I've got 2 or 3 VT100's, but they're so buried it's going to take a lot of work to get to them so was hoping to get an idea if there is room first. Basically I'm trying to build a PDP-10 into a VT100 by using an Intel D810EMO MicroATX board. Zane -- | Zane H.

Power connectors

by tniemann＠msn.com

Hans.... I may be wrong in my explanation to the following question you posed but I will give it a shot.....You said: I don't know any reason why the system has to be keyed, I always assumed the US development of keyed plugs was triggered by old DC systems (since in DC Eq. it is necersarry to know the orientation), but not a new addition. Strange, we dropped all orientationwhen switching to AC (with Protective Ground). Could anyone give give a reason why the system has to be keyed _IF_ a Protective Ground is included (other than define the Protective Ground pin) If you hook an scope up circuit such as a TV and hook the ground probe up to signal ground but you have the plug reversed the circuit will short out and you will blow the device you are testing. That is because you just provided a current path to frame ground for the signal which you thought was signal ground. TV repairman who have used scopes have done this more than once.

Boot Disk Needed

by Lee.Davison＠merlincommunications.com

> /u = Unconditional, it will do a real format, as opposed to > quick format > /U - unconditional, prevents checking of sectors for read errors before formatting them.

Hey there. I was wondering if someone could help me break into the privileged mode on my DECserver 700 without the password. Do I have to remove the RAM, the battery, or something? Thanks. Peace... Sridhar
