If you go to Seagate's website (www.seagate.com) you can find pages for conner drives... it'll have graphics which show the positions of jumpers.

The RZ23 (there are two different ones) are either 105 or 120mb SCSI drives. The group of three(6pins, arranged 2x3) are the address. Check the various vax archives for more specs. Allison

It's generally in RAM but as noted there are plenty with bom based kernals and OSs. Allison

<u have a GRiD Compass with bubble memory, you get an OS <that acts like it's in ROM, but bubbles are writable. Lessee here. My supercrate s100 has CPM/BIOS/Monitor in rom. takes about 3sec to selfcheck and boot. I have an s100 crate with a 2mb write once romdisk of my design. I also have a z80 system with an two intel BPK72 bubble memories on. Each one give 128kb of space. All easily predate the GRID. Allison

Would it be possible to have a control chip and a OS chip? You've got the control chip, which contains address information on the OS chip, as well as other EXTREMELY basic ssytem info. Then you've got the OS chip, which contains the OS. Because of the control chip, it could be as large as you wanted it. I've also heard of a "Windows 98 on a chip" system, with 75MBPS through put. Sounds like the first decent way to load Windows... Ciao, Tim D. Hotze PS-Did any computers have GUI's built in?

No, PDF is more-or-less PostScript. However, *some* PDF documents actually include scanned images, which of course are usually bitmaps because the creator didn't OCR them. Both PostScript and PDF files can contain text, vector graphics, and bitmap graphics. -- Pete Peter Turnbull Dept. of Computer Science University of York

Acorn's RISC PC has the OS (RISC OS 3.7) in ROM, about 4MB IIRC. The original Archimedes range (1987) had RISC OS 2.0 in ROM (512K, IIRC). Usually they're mask ROMs or OTPROMs. The OS is structured as a series of about 80 relocatable modules, so if an upgrade is required, you load the relevant replacement module into RAM, and the kernel changes the links that point to it. Of course, changing the kernel module itself is a little more tricky, but it can be done -- the first RISC OS 2 upgrades had instructions on how to boot the system from a disk to load a new "utility module". -- Pete Peter Turnbull Dept. of Computer Science University of York

Bob. MSX. Robots. AI. Home automation. >The Z8000. The iAPX432. Parallel processing. Voice recognition. Pen-based computers, although not a BOOMING success, have had a limited success. Their gaining momentum, too. Robots? Once again, go into a factory. You'll see them at work. BTW, how rare are Androbots? Wireless networks? I've seen a fwe. But I'd like more tech behind them. Bob? He was way cool. Then he died out. Too bad. AI is very much in a state of recession, as early depressions in the 80's took all the hype out of it. I say that we saw the last of current AI's with Deep Blue last year. They'll come back, but not until 64-bit is standard. Voice recognitions much the same as AI, but with a little more life, as it actually has some practical applications that are already partially-functional. >What did I miss?
