I got bit by the Gas-Powered RC Truck bug so I decided its time to get rid of some parts that I'll probably never use. Darned siblings with their cool toys! Anyway, everything is working, as near as I can tell, and 'or-best-offer'. I won't ship the LaserWriter, but everything else I'll ship at the buyer's expense. I'm located in Bloomington, IN 47408. If you have any questions, feel free to email me.

Now OT: Speaker boxes... [was:: I hate Radio Shack]

My head has two speaker jacks, so I can have it see 2 8 ohm speakers, or wire in a homemade adapter so it will see a 2 ohm load. I've been thinking about wiring in some DPDT switches, so I can flip each side between 2 & 4 ohms. Depending on how much you travel with those speakers, here's how I would set up the boxes... - 15" in a ported box, all by itself. It'll be heavy. Nice boom for the bottom end. - 4 x 12" in a sealed box. Good tight response, but still has the bottom. This could be used by itself quite nicely. - 8" (or two) in a sealed box with a good horn tweeter. This would go best used with the 15" cabinet, and an appropriate crossover. Maybe your amp has one built in*. It will also be good for practicing by yourself. Nice & tight response, and great if you play some funk style too. * My Peavey does have a built-in adjustable crossover, but it's pre-amp level. I then have to amp each side after that. One would get looped back into the Peavey, and the other to a second power amp... And hopefully you know the make and model numbers for those woofers. That will be required if you want to build the best boxes possible for them. I picked up the 2 speaker design books from Radio Shack to help with the box design. Blaupunkt also has a basic DOS program to help with box design too. The RS books had some decent rough size info for speakers, so I assumed some average-low specs for my 12s went I calculated the box size. I know the box is a little small for them. you can kinda hear it. But I don't have the test equipment needed to find the real specs for these drivers, yet :) I'm working on a spreadsheet that has all of the formulas built in, to help design different boxes. I'm not sure if I have it finished yet or not, though... -- --- David A Woyciesjes --- C & IS Support Specialist --- Yale University Press --- (203) 432-0953 --- ICQ # - 905818 Mac OS X 10.1 - Darwin Kernel Version 5 Running since 01/22/2002 without a crash

OT - DDS-2 drive errors on Microvax 3100, VMS 7.3

by bob_lafleur＠technologist.com

It seems like we get a lot of VMS questions here, which probably doesn't really fall directly under the list rules. I'm guilty of it too. But there's so much knowledge here, it's hard not to ask. If anyone can point me in the direction of an active VMS mailing list, I'll ask my VMS questions there instead. And if there's not one, I'd consider setting one up if there happens to be any mailing list software that works with Exchange Server 2000. ----- I've got my ARCHIVE Python (model 4326) DDS-2 drive connected to my MV3100. It is connected to that machine only (I don't have it dual-connected, as discussed in another message thread) and it's on my 2nd SCSI controller chain. When I first boot the system, the first restore I do from tape I get this message: $ backup mkb100:rob/save *.* %MOUNT-I-MOUNTED, ROB mounted on _BOB$MKB100: %BACKUP-E-READERRS, excessive error rate reading MKB100:[000000]ROB.; -SYSTEM-F-CTRLERR, fatal controller error %BACKUP-I-OPERSPEC %BACKUP-I-OPERASSIST, operator assistance has been requested I then get "fatal controller error" messages whenever I try to access the drive, until I turn it off and back on. After the above erorr, the device shows 102 errors in SHOW DEVICE. Once the drive is turned off and back on, it works fine from then on, with no problems. If I boot the system, then turn the drive off, and back on, I *still* get this message for the first restore I do. Then I turn the drive off and back on, and all is OK. If the first operation I do after booting is a backup TO tape, it goes fine with no problems. But then when I try to do a restore from tape, I still get the above error. I've updated the drive's firmware to what I believe to be the latest (28388-XXX V5.AQ). Right now I have the drive in an external enclosure to test it. I was going to mount it internally in the MV3100, but if I have to power the drive down to make it work, then internal mounting is not possible. Could it be a SCSI termination problem? The drive works flawlessly on my PC. Thanks, - Bob

IMSAI News?

by r.stek＠snet.net

Bob Shannon - Could you expand on your comments about non-s-100? According to the website, it has a 10 slot S-100 MB, and "The IMSAI SERIES TWO utilizes the powerhouse Zilog Z8S180 microprocessor and provides a complete system on an IEEE-696 compatible S-100 board" I am somewhat interested in the machine, but not if there is NO chance of using some of my other S-100 boards in it.

UCSD P System (was: Why is it that ...

This is NOT the UCSD p-System filer, it's one belonging to a derived version of it that Apple briefly used on the Apple II. To give you a little context, this was version II of the p-System (the Roman numerals denoted architecture versions). The one released by SofTech Microsystems, on the IBM and the Sage and many others, was version IV, and it was a major overhaul. (Status of segments regularised, almost no limit on the number of segments in a system, all units swappable, dynamic linking, instruction set even more compact than before, procedural parameters, conformant arrays, semaphores, processes, etc. etc.) Including using 80 columns on the screens! (Actually you could change that in SYSTEM.CONFIG if you needed to, as seems clearly to have been done with this example). The filer used full names in its menus when it had the screen width to do so. Which was most or all of the time after those very early screens, unless, as I say, you did something to SYSTEM.CONFIG . As for making DOS look good, it made it look dreadful. I still remember the pain of migrating to Turbo Pascal, which was the BEST that DOS had to offer. Tiny file names, NO file typing (file extensions are NOT file types), terribly slow floppies, file volumes WITHOUT NAMES (which continues to this day), every program needing all its code linked into it statically, hence several copies of the same code on the same floppy -- etc etc. (DOS's only advantages: more flexible number of entries in a directory, and borrowing a poor man's version of directory trees from UNIX. The p-System only allowed 77 entries in a directory -- that was from a time when the DEC PDP-11 was popular -- and had only 1 level of "subdirectory", which was an actual subvolume file, of fixed size. And DOS was to acquire networking, whereas work on the p-System seems to have suspended before that could happen.) Oh, and the p-System had powerful wildcards, including use for mass name changes. DOS's wildcards were always weaker, and buggy. And I really did like being able to compile on a 68000 machine and run the compiled code on an 8086. Much faster turnaround time. (I once did a project where we were supposed to use the then-Microsoft Pascal on XT's for compiling -- all in native code of course. We stayed in UCSD Pascal and compiled within the p-System because it was FASTER!) > > >You may remember what those letters stand for, but I don't. > > ... > > > > For those not wanting to chase the link, it says: > > > > Filer: G, S, N, L, R, C, T, D, Q [1.1] > > > > Don't you remember?

PET and Magic Sac+

by foo＠siconic.com

I found two interesting items today. One is a PET 2001-8. It has the regular keyboard. Inside was an "expandaram" board that added additional RAM and some peripheral slots for the PET. The cards plugged in looked a lot like Apple ][ cards in their form factor but I assume this is some proprietary bus. Anyone have info on this? Also, found a little module that apparently plugs somewhere into an Atari ST. It's called the Magic Sac+ and on it it says "Turns your Atari into a Mac". Anyone ever use one of these? Where on the ST would this plug in to? Or is it for the Mega ST perhaps?

"Windows V1.0"

It's not much help, but the first Z248 that we recieved had MS-DOS 3.x and Windows 1.0x floppies included with it. I've never seen a copy of Windows 2.x, however, oddly enough I recently found a shrinkwrapped copy of Windows 1.0 in the trash! On a vaguely interesting Windows 1.x note, the PC version of the game "Balance of Power" included just enough of Windows 1.x to run the game! It was the only use I ever had for Windows 1.x :^) Zane
