FYI... John Draper was arrested and convicted in Pennsylvania in '77 or '78 for "possession of a device capable of defrauding the telephone company of its rightful tarrifs". I met him on his journey back to the left coast after he got out. The device in question? The Apple (autodialing) Modem, which he was developing for Woz. Why? Well, Woz doesn't like to do too much in hardware; he always like to minimize the logic design and use software to do the job (a great philosphy for controllers, a louosy one for general purpose computers). So rather than design the hardware to have fixed-frequency tones, the software could determine the tones to be used. Of course, that meant you could select the ESS interswitch "MF" tones instead of DTMF. Today, virtually every modem with a Rockwell chipset has this feature. Has Rockwell been locked up? Unlikely... -dq -Douglas Hurst Quebbeman (DougQ at ixsnayamspayIgLou.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

I imagine you'd be carted off to the funny farm :-) I assume you were not serious but just in case ... Your path to the Qbus widgets would be: LSB->XMI->BI->UNIBUS->QBUS which I suspect is a tad tortuous even for the normally well designed DEC stuff. Bus adapters generally only work well one bus down. Beyond that you start to hit timing issues and other such trivia such as locking. As an aside, surely with a little bit of thought you could get TURBOchannel and PCI involved in there? How hard can it be? Antonio

CP/M and Imsai

by caprio＠dcms.com

I'm new to this news group and the S-100 world so my appologies in advance for what may be stupid or common knowledge questions. I purchased an Imsai 8080 and would like to run some version of CP/M. Should I stick with Imsai's IMDOS, which we know works? If CP/M is doable What version would be the best choice? Does CP/M need some sort of BIOS like the PC? If so where do I get the BIOS source in order to burn an EPROM? Any help, pointers, URL's, etc wouldbe greatly appreciated. Thanks.

As stated by 2600 Enterprises in its >post-hearing brief: "Jon Johansen testified that . . >. he wrote the program for Windows rather than for >Linux in order to test it properly because Linux did >not then support the UDF file system used on DVDs." Um... can you explain then, if this is what the lawsuit was about, WHY it was deemed illegal to post or link to, copies of the SOURCE CODE for the DeCSS algorithm. After all THAT is what 2600 was arguing. They didn't disagree that an executable could be used to pirate a DVD. Nor did they flat out disagree that distributing it might not be such a hot idea... what they were fighting for, was the RIGHT to post and say anything you damn well please. If you stop people from posting source code, even if that source code when used serves no purpose other than to commit a crime... you are STILL crushing free speech. There should be no law to stop it... much as their should be no law stopping me from explaining in detail, if I so choose, how to commit murder and get away with it. There is no practical application for executing the knowledge of how to commit and get away with murder, but that doesn't mean that one should be stopped from sharing that knowledge. The moment someone puts the knowledge into use for illegal purposes... THAT is when the law should step up and prosecute someone. But since there are already laws in place that appear to cover the actual illegal activities... then things like the DMCA should just be repealed... they are redundant in places of stopping actual crime, and they cause things that should not be crimes, to now be listed as such. What amazes me is... it has been deemed in a court of law, that it is free speech and ok to publish detailed instructions on how to build an atomic bomb. But it is illegal to post instructions on how to play a DVD that I bought, on a computer that I bought, using an OS that I bought. You can't go around assuming that everyone, when given the chance, will be a criminal. Gee... NJ did that, and now they are 160 million in debt with their EZ-Pass system... why? Because they figured that they would be able to pay for the system from tickets issued to toll jumpers... but funny thing is, they have now found out the hard way, that 99% of the population of NJ is honest... and now the state is stuck with the bill to pay. -chris <http://www.mythtech.net>

New Finds today and HELP needed on Apple card

by jrkeys＠concentric.net

Today was busy at doing a auction most of the morning and stopping at several thrift stores all afternoon. Below are some of my finds and a strange card. 1. Mac Performa 630CD (was $5.99) 2. Mac Performa 6110CD (was $7) 3. View-Master InteractiveVision console in the box it was used unit missing the VHS tape that comes with it. (was $18) 4. Laser 50 personal computer (was $2.92) 5. AT&T Globulyst 378TPC tower model 3348-4372 (was $8) 6. Two hp front cartridges (22706C and 22706M). (was 80 cent) 7. Where in Time is Carmen San Diego cartridge by Konami for the Nintendo NES in a box with a desk encyclopedia. (was 79 cent) 8. Six different CD's for the Panasonic 3 DO system. Looked all over store and asked the clerks if they had the game console. No Luck finding it there. (these were .99 to $1.99 each) 9. Several old monitors for $1 each. 10. Now this the card: It says in caps MOTOROLA M68HC05PGMR. One of the chips has a homemade label on it that says METER.MIK CKSUM BF73. There are 2 switches on one is a ON/OFF and the other looks like a reset switch. There is a number in bold white of 3189.Three wires are coming >from one side and they are purple, blue, and black in color. It looks like some kind of EPROM burner to me? Anyone have info on this card? (was $1.99)

I should have been more specific... the screws to which I am referring are those commonly provided for securing the cards in their slots. And they shed metal not only from the screw but from the rear of the chassis they thread into. In fact, everytime you insert one of these, it has a 50% chance of rethreading the hole. Look at them carefully... they have a noticable taper. That's *one* way to encourage them to stay put. -dq

Any chance of a photo? heh, believe it or not, there are two different, unreleated things called "top hats" in some Primes... In my 2455, at the top, underneath the removable top skin, is a small +/- 12VDC power supply, called the "top hat PSU". But the 750 wouldn't have had those... in the link below, they are the three small rectangular vertically arranged; my 2455's boards run vertical in the cage: http://members.iglou.com/dougq/p2455/ICS&Cipher.html OTOH, in the 750, the boards went in horizontally, so you'd have seen the top hats left-to-right (at least that's how they were in the P400 and the P650).

Steve- You're one of several listers with whom it appears I have read-only contact with. My replies never seem to get through. If your PSU is a TLA10113-001, no, I don't need it; OTOH, if it's a 7778, then I *might* be interested, they are apparantly rather rare now. They put out the +/- 16VDC used by the older memory cards. There will come a day when someone will need one, and no more will be found. Can you at least check the numbers on it for me, so I can make an intelligent decision? Ok, then at least an *informed* decision... ;) -dq

Speaking of machined parts versus something else... Anyone notice how commodity PCs have screws that have clearly been *cast* onstead of *turned/Machined*? Everytime you thread one into a hole, you generate a nice supply of metal shavings. Not good. To get back on topic, when did this trend start? The IBM PC, PC/XT, and PC/AT used machined/turned fasteners. Lots of classic non-consumer hardware used various "captive mechanisms" instead of plain old screws and bolts. And how about sharp edges inside a chassis? Older hardware tends to have spent a little time in the hands of a whitesmith, who added lots of finishing detail like smooth edges that don't cut. -dq

ZX81 and 6116

They've been piling up in a box and today I finally got to them. Here's what I found: All of the 1K boards had two 2114s and no jumper installed. All but one of the 2K boards had a single 2016 and L2 was installed. One 2K board had a 6116 and L2 was installed. The board was operational and appeared unmodified. I replaced a socketed 2016 on a working board with the 6116 pulled from the above-mentioned board, and the board still worked. So I think it's safe to say that L2 is required for a single-RAM-chip board, and that a 6116 is a drop-in replacement for a 2016. Never did see a 4118. Perhaps the use of it would change things, jumper-wise. Glen 0/0

Never seen one, but if I had, I would own one by now. As for a more common system (more common than the Intergraph, not the Amiga), a UnixPC with 1 meg of ram, and maybe 60MB of disk will give you access to a really decent subset of available Unix (and possibly MS-DOS) software. It will also have a decent development environment, given the installation of a dev kit. On the other hand, the Atari ST plays quite a few more games. :) Chris Christopher Smith, Perl Developer Amdocs - Champaign, IL /usr/bin/perl -e ' print((~"\x95\xc4\xe3"^"Just Another Perl Hacker.")."\x08!\n"); '
