D'oh! Backup issue solved

by ajp166＠bellatlantic.net

In this the obvious is the words... painfully aware. I have the Adaptec, you get it with their SCSI cards. Not the same as backup though as its controller specific, or it seems to. Tried it once to go from SCSI to IDE and it barfed. Plextor has a tool for this that comes with their CDrw. Obvious limit is you have to have CDW to create and CDr to read and the ~650mb limit of cdroms. Also used is good old 6120 tape (IOMEGA), ok, but so so reliability. There is the OnStream tapes and their tools, not bad but W9x and NT4/sp4 are it's minimia, 30gb! Best for low end SOHO, it works well in both the parallel port and scsi version. The *nix dd tool is a universal screwwrenchdriverhammer! ;) There is DriveImage but the one time I needed it to work it made an impressive mess of the partition table. It seems to want the target partitions to be exactly like the source partition and formatting <bad if you want to go from fat16 to fat32 or NTFS>. Xcopy(32) <dos, win3.x, W9x, NT> does the job ok for any disk/directory at the file level but cannot do the disk low level stuff needed to replicate <clone> a configured system. DOS backup/restore aka hackup and destroy... need i say more. Later DOS MSBACKUP was far better and incompatable format with win9x backup both of which are unintelligible to NT backup. Why VMS backup is better. I can take an image copy of any disk so long as its smaller than the target volume and replicate all of the structures and files. For example a copy of VMS5.4-3 on RD54 (MFM 160mb) to a CMD interfaced RZ56 (680mb scsi). and have a fully useful bootable disk that was not truncated. Or I can do that through an intermediate set of TK50 tapes. This was handy as I needed to install VMS once and I could copy it to N-many systems exactly as created. Maybe this works as there are a common set of standards. This is clearly lacking in the PC realm(non *nix based).

Ni-MH pack topology [semi-OT, I know, sorry...]

by yoda＠isr.ist.utl.pt

I was wondering whether anyone here could help me on this one: I have a battery pack of a mobile phone I'd like to replace for a set of AA Ni-Cad batteries (reason: cheaper!). The mobile phone even has the necessary mechanical/electrical pieces necessary for the mobile to work with 4 AA batteries. The question is a couple of extra small terminals the pack provides. I dismantled the pack and I found out that one of them was connected to the pack (-) terminal, and the other one was connected to a weird component, which is connected to the (-) terminal. My question is: *what* weird component is that? Some clues: It looks like a common 1N4148 diode: glass capsule, two small copper-color cylinders, and something really small in between. However, it is not a (common) diode! However, I suspected it were a zenner pair (in series, symmetric polarity), and therefore I tryed to measure the zenner voltage by connecting the component in series with a 1K resistor, to a variable voltage power supply. In fact, varying the voltage does not affect the voltage drop across the component, remaining at 9.1V. At this time I was pretty sure it was a zenner pair, maybe for protection or something like that. However, the mobile does not charge the batteries (and does not recognize their presence) if this component is removed! The mobile charger has about 7V (open circuit), so I was expecting the supposedly zenner pair to be "open". What I did was to measure the extra pin voltage: without the component it measures about 2.5V, *with* the component it drops to about 1.2V. So the component cannot be a zenner pair. And this was the time I had the idea to post this message... Thanks for any help/clues/(flames?) given!

Ni-MH pack topology [semi-OT, I know, sorry...]

by yoda＠isr.ist.utl.pt

Thanks for the replies! It cannnot obviously be a plain fuse, since it is not short-circuited (assuming it's still ok). I guess the most plausible idea is that it is just some kind of thermal-dependant component. Maybe a NTC or PTC. Still, how could I replace this component? I should characterize it electrically.

VCF Requests i.e. liquid and solid fuel (O.T.) White Castle Belly Bombers

by mmcfadden＠cmh.edu

Regarding White Castle Burgers While living in St. Louis in the late 70's there was an article about the origin of the White Castle burger. Square burgers with holes to allow them to cook rapidly, normally cooked with onions. Easily consumed by the dozen since they were about 3" squares. Originally only available in St. Louis, there were a bunch of White Castle fans/fanatics in Arizona who would order a refrigerated tractor trailer full every year and would have a huge bash to consume them. Now they are more widely available. Best with massive quantities of beer after the bars close. Rumored also to stop any chemically induced munchies. Any printout that was generated while you were eating them smelled of onions and grease. Mike Burger biter

FREE: 2 TI Silent 700 terminals (Austin, TX)

by mrbill＠mrbill.net

I've got two TI Silent 700 terminals with cover / carry cases (one model 765 with the bubble RAM expansion, one standard 745) free here in Austin, TX. I'm getting my ham radio license soon, so some of this stuff has to go to make room for a table full of equipment... If anyone is interested, let me know. I *might* be persuaded to ship these if I cant find local takers.

D'oh! Backup issue solved

>Novaback, Cheyenne, various versions of Arcada/now-Seagate-Backup or Backup >exec, and a few others as well, work OK on small devices but I've yet to see >one of them even work with a single 8mm tape (10-15 GB capacity), let alone I'm using replica on a HP T20, tehats good enough for my needs. Then again I don't have 100gb of disk unless I total ALL the clients together. I think it's a case of storage out srtipping the 32bit cpus and storage that was only 25gb a year ago and now it's 75gb. I havent a clue how those guys with their terabyte fields of disks (a table full) do it. Allison

Ni-MH pack topology [semi-OT, I know, sorry...]

It's a self resetting fuse like device also there are ICs of the three or even two legged types to monitor battery temperature.
