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.

No, I didn't find a Cromemco. I did find, in a box of stuff that I thought was all Fortune 32:16 stuff, a loose-leaf binder with 200-300 pages of Cromemco documentation. It says on the flyleaf: This manual was produced on a Cromemco model 3355 printer Using the Cromemco Word Processing System, There is: Cromemco Fortran IV Instruction Manual - copyright 1977, 1979 Part 1 Fortran Reference Manual Part 2 Fortran User's Manual Cromemco Macro Assembler Manual Cromemco Macro Assembler Manual Addendum - dated January 1980 It's single-sided printing (not great quality), at a quick glance it seems to be all there, and it's in excellent condition.

(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.

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.

I should have read one more message! > > - don I never am as clear in some of my posts as I'd like... The kind of screws I'm lamenting are cast, and cast poorly... I assume everyone knows what casting flash is... these screws have casting flash... when you thread them through, the sheet metal eats at the flash, and you get metal bits from that, and at the same time, the part of the flash that doesn't come off quickly reams the sheet metal to death. *Buy* quality screws? There is an advertisement showing here in the U.S. Midwest for an office supply firm. The scene is set in a "typical" office... some shirts are having a meeting, when another shirt comes in and asks if "can we use the pen"? THE pen. The only pen in the office. When I need a screw for a PC, I typically have to find a PC >from which to remove a screw. Everything ends up with half the screws it was designed to use. Now, we just bought 25 Dells that don't use very many screws. Where oh where will I get a screw when I need one? -dq

I think he's possible spreading himself a bit too thinly, but then I resemble that remark sufficiently that I'll not be criticizing anyone for it. I've had a few hobby-related things go so far south before that it left me in a seriously deep funk for, well, years. But forgiveness can be liberating, and the good things that have been happening that last few months to the last year more than make up for it. Sometimes, you just gotta take the long view... -dq -Douglas Hurst Quebbeman (DougQ at ixnayamspayIgLou.com) [Call me "Doug"] Surgically excise the pig-latin from my e-mail address in order to reply "The large print giveth, and the small print taketh away." -Tom Waits

Headstart Explorer

by jbstuart＠gulftel.com

Hi Mr. Clausen, I have been seeking help on my Headstart Explorer XT computer made by Vendex. I cannot seem to restore it after formating the 40 MB hard disk, Automagic. I have all the original disks that came with it when I bought it new in 1990. The Master Disk says to put it in the A drive and then turn on the computer. I have done this several times and it does not seem to work. I have the other disks, DOS System Disk #1, Programs Disk #2, and Disk 3. I would appreciate any assistance you may give me. Thanks, John

Yeah, there is the old 7400 series arithmetic unit... But in my experience, most pre-micro computer equipment used fusible-link ROMs for truth-tables; a transitional item, the Processor Tech SOL's keyboard, is a good example of this. -dq

It would probably be a worth while upgrade, BUT it would also require a backplane and memory upgrade, and as I recall he doesn't have a budget for this. As for the price I don't remember, but I know they've come down in price (I got mine as part of a trade). Zane

SCSI options for PDP 11/23

by tom＠sba.miami.edu

After my recent RX02 problems, I've decided I'd like to add a SCSI controller in my 11/23, and keep my programs on a hard disk. What Q-bus controllers will work with RT-11? What's the minimum version of RT-11 that I can get by with? Can I use any disk, or does it have to be something in particular? Thanks, Tom
