Weird...I dunno about the RM03, but I ran an RM02 on a Dataram Qbus SMD controller (I don't recall the model number) many years ago in an 11/73. It worked fine. I thought the only big difference between the RM02 and the RM03 was the spindle speed, though. -Dave -- Dave McGuire "I thought it would go quickly, St. Petersburg, FL that rubberized bottom..." -Sridhar

Ultrix root password

by broth＠heathers.stdio.com

I snagged a PDP11/53 and Two MicroVAX II's today at the salvage yard. $5 a piece. Doesn't happen very often but feels good when it does. The MV's have Ultrix on them and boot fine BUT..... Is there an easy way to bust the root password for Ultrix on the console? Thanks, Brian.

> I'd heard being able to read 7-Track's was a lost art. The problem is finding a drive with a 7 track head. The stuff has been out of production for 30 years and people stopped making 7 track head stacks a LONG time ago. I've been looking for one for a couple of years now. Heck, I'd be happy just to find a 7 track head stack.. I'm still kicking myself for missing the 7-track TU10 that was on eBay a couple years ago.

I brought in my squeeze-to-wrap wirewrap tool, and showed her how to use it. This pleased her quite a bit (not to mention her supervisor).

This all depends on which model Poqet you have. The information on Brian's site applies to the first two models, the "Classic" (PQ-0164) and the "Prime" (PQ-0181). The last model, the "Plus", _can_ use SanDisk Flash cards up to at least 110MB. See http://www.olagrande.net/~webguy/service/poqet.html#Useful.

(I think) > > > Some SRAM that will operate at (is the low voltage 3 or > 1.5 on those?) > > > the lower voltage would probably be good too. > This is old... I'm pretty sure the PCMCIA is 5V only. Again from the FAQ: What kind of PCMCIA cards can I use in my Poqet PC? The PCMCIA slots in the Poqet PC actually predate the PCMCIA specification. The slots are generally compatible with Revision 1.0 of the PCMCIA spec. The Poqet's PCMCIA slots have a Type I (2.5 mm) thickness. Generally, the only thing that can be put into the Poqet PC are SRAM cards, which can be formatted on the Poqet PC for use as RAM disks. The Poqet PC does not read the Card Information Structure (CIS) on SRAM cards to determine the proper format, but instead uses a uses a "pseudo-floppy" format. Generally cards formatted on a Poqet PC can be read by other computers, but cards formatted on other computers may have to be reformatted before being used on the Poqet PC. To work in the Poqet PC, SRAM cards must be PCMCIA Revision 1.0 compatible and must be able to operate at 3 volts. As far as memory cards are concerned, however, there isn't much difference between PCMCIA 2.0 and 1.0, so Rev. 2.0 memory cards should work fine. The 3 volt requirement arises because, as the alkaline batteries in the Poqet PC die, the system voltage can dip down to the 3 volt level. If your PCMCIA cards operate only at 5 volts, then you could lose data as your batteries die. One thing to remember is that all SRAM cards will retain data at 3 volts. To work in the Poqet PC, the SRAM cards must operate (read and write data) at 3 volts. ----- 3 volts, definitely. > IBM has things like the "MicroDrive", but modern PCMCIA disks tend > to specifically be "CompactFlash Type III" - you can get CF->PCMCIA > adapters cheap, but you'll probably have to alter them mechanically > to provide clearance for the HDA of a MicroDrive.

It's not magical, just cool. You can also True, but Linux didn't like my laptop much last I tried, nor did NetBSD. Right now it's running Eth's "PC Native Oberon," and is perfectly happy, but I don't think Oberon will drive its PCMCIA slots, and I don't have much breathing room on that system anyway, even though the full install of Oberon is probably smaller than that of DOS on the same system. > pick up a PCM "Swap Box" for typically under $50 that puts a single > Type-II/dual Type-I PCMCIA socket in your ISA-equipped desktop.
