Well, it IS a serious matter for ME. If Jay is going to make this list hostile to people who actually run their entire business operations on Classic computers in the Classic manner (and exercise their right to use their own servers and not someone else's for sovereignty reasons), it looks like those of us *TRULY* into Classic computing need to start our own list (hosted on a Classic list server of course). der Mouse, can I count you in?

Free: HP mini cartridges

by rigdonj＠cfl.rr.com

More finds from today's trip. One HP mini-cartridge factory marked "DGL Demo Mini #2 Mini Cart, PE, FMGR 24998-13309 Rev 2040". I don't know what the software if but someone here should know. The other tape appears to be a backup. It was orginaly marked "DB1000 CRTG#5" but that has been marked out and "!BCK03 R2540" has been marked in pen. Joe

Free: Tektronix Plot 10 mag tape

by rigdonj＠cfl.rr.com

I went scrounging today and found this. I can't use it but it's too good to waste so I thought I'd see if anyone here could use it. It's on a small tape spool and is marked "4010A01 Plot 10(R) Terminal Control System Level 5.01 (C)Copyright Tektronix Inc 1988 Format IBM ASCII 1600 BPI Label: None Serial No. B074512 Record: 80 Block: 800 Option: 08".

Catweasel opinions, sources of info etc.

by curt＠atarimuseum.com

Jim, I understand where you're coming from, however the way the product was presented, it stated it could read various formats, what wasn't mentioned on the site for the product or during the purchase process is that the "product is capable of reading such formats - if someone actually writes the code" My Atari 800 could run linux - if someone ports it, could run CP/M too if someone wants to write the needed code, could read IBM disks on its disk drives - if someone writes it... All of our equipment can do a lot more then it is normally capable of --- if someone takes the time to write it. So what I'm saying is I bought the product because it stated it could do certain things which I was expecting out of the box when I bought it, just there was no fineprint saying that there were no actual s/w or drives to actually make the card work that way yet.

I think I looked there a while ago and gave up > when I saw how many PC posts there were. Actually it's alt.comp.hardware.homebuilt, and it started as a group for people interested in building or modifying hardware in the sense of using a soldering iron or perhaps VHDL, but gradually newbies started appearing and asking about PCs they had "built" in the sense of sticking their ISA cards on a new motherboard. At first they got politely asked to try elsewhere, but quite quickly, first one or two, then more, other newbies started saying "well, it was a polite question, with a simple answer, so why not just answer it?" and in quite a short space of time the please-help-me-fix-my-PC brigade outnumbered the on-topic posters by 100:1. Various solutions were tried but too late and all failed; eventually all the regulars moved elsewhere. Some started a new group called comp.arch.hobbyist; maybe not the best choice of name. It gets about one post a week. On a good week. -- Pete Peter Turnbull Network Manager University of York

Age

by alhartman＠yahoo.com

Well, I'm about to be 43, born June 21 1962 (exactly a year older than one of the other posters recently...). I first encountered Personal Computers in 1978 at a Star Trek Convention where I poured $20.00 into a .50 a game Star Trek Game hosted on a TRS-80 Model I. I asked the author for his address so I could buy a copy, but I guess he thought that a 17yo kid would never buy a $1000 computer. By January 1979, I was the proud owner of a TRS-80 Model I, Level I, 16k computer. The Manager of the store said I didn't need Level II. Turns out he was having problems moving Level I machines, and was stuck with this one.. LOL! Shortly thereafter, I upgraded to Level II and went to work for Radio Shack. I bought an expansion interface in 1980 and I think I have the singular honor of being the only person I know whose warranty was voided BEFORE I took the E/I home. Being that I worked in the store, I took it home BEFORE I had finished paying the layaway, installed the 32k of RAM I had bought mail-order, tested it... And brought the unit BACK to the store. I bought my first Floppy drive for $321.00 which was an MPI drive that ejected floppies like a toaster. We never got that drive to run... I then got a Wangtek Flippy Drive (Two sided by turning the floppy over, it had two sets of sector hole and write protect sensors) and a Percom Doubler. I worked for an LNW Dealer in NYC (Stoney Clove Computers) and coveted an LNW Model I for some time. I also worked for Lawrence S. Epstein Assoc. and sold Corvus Hard Drives for the Model I/II/III, etc... I almost bought a ZX-80 instead of the Flippy Drive at the Trenton Computer Festival in 1980... Over the years I've owned just about every American Micro Computer: Atari 400/800, Atari ST, Amiga 1000/500, Apple IIe, IIgs, IIc, Laser 128/128ex, MacPlus, Duo 230, PB 1400, Wallstreet G3, PowerComputing Power Center 132, Power 100, ZX-81 (built in an hour from the kit), TS1000, TS 1500, TS2068, ZX-Spectrum (American Prototype), Coco I, II & III, All sorts of PC Clones starting with an American XT (8mhz Turbo V20) and currently with a self-built P4 3.2ghz. I worked for Zebra Systems and Spectrum Projects and developed a lot of products for the Timex/Sinclair and Color Computer Community... At Zebra, I used and fell in love with an Imsai 8080 upgraded with a Z-80 board. I did a lot of "typesetting" with a program called "FancyFont" on CP/M using an FX-80 printer and eventually a Laserjet 500. I also co-authored the Coco Greeting Card Designer while at Zebra and worked on the SC-01 Votrax Speech Synthesiser implementation on the ZX-81/TS1000 and the TS-2068. Two of the dream computers I'd like to own is an Imsai and an LNW-80 Model II. I ran several BBS's in the mid 80's: Rainbow Magazine BBS (5 lines), Omni*Net BBS, Outpost-80 BBS, Computer Concepts BBS, Zebra Systems BBS using mostly TBBS on TRS-80's. I helped develop a fork of Connection-80 BBS in NYC called "Nybbles 80" BBS with Paul Oves and Stoney Clove Computers. I added threaded messaging, passwords, and color... I was a Novell CNE from 1989 - 1996 (I never upgraded to 4.0 and above). Today, I am a network engineer supporting MacOS X Servers... I can't imaging my life before I had computers in it... I still have my TRS-80 Model I which has been heavily modified using the TRS-80 and Other Mysteries Book by Dennis Kitsz. It has Lowercase, High Speed Mod, Alpha Joystick built in, Reset Switch, Internal speaker and Amp, Composite Video Out, better keyboard with keypad... It's not working right now, it won't recognize either of my E/I's. It was stolen twice and recovered due to all the mods. It was easily identifiable, and I got lucky to get it back twice when stolen. I just bought a Mac Mini to add to my collection, and am selling my G4 500 on eBay to fund it... I put $50 into the coupon for an AmigaONE, and may be getting one of those this year too. That's it!

Windows LFN's (HP NewWave)

by julesrichardsonuk＠yahoo.co.uk

Just found the following snippet in a 1990 document (someone's review of a GUI show which they'd attended). Just struck me as interesting in that I never knew there was an alternative to 8.3 filenames in the DOS/Windows world prior to Win95, nor have I ever heard of HP NewWave before... Apparently also included macros/activity recording, associations between data and application (e.g. double-click on a spreadsheet file and it opens in the spreadsheet app etc.), and context-sensitive help. Sounds like a winner, only I've never even heard of it... Apologies to the original author (who almost certainly isn't on this list!) for the cut & paste! (I do like that first line :-) ------- NewWave is a 'front end' to MSWindows to make them useable. It provides a Filer facility which tarts up the MS-DOS filing system to enable 30 character filenames with no obvious character set limitations (ie it'll accept a space in the filename) and a framework to interchange and combine multiple data types into one document. This framework manages dynamic links between the document and the original object which is contained in the document such that when the document is reconstructed any changes to, say the spreadsheet data, get reflected in, say, the report. Parts of foreign objects can also be imported with the same results, eg a few rows and columns of a spreadsheet can be imported to a word processed document.

picking locks

> Now that is weird. I read somewhere (or saw a survival show) that EVERYONE >should carry a center punch in their cars just in case you car gets >submerged in water. Use the center punch on you side windows to get out, >otherwise it would be impossible to open the door.... Although I can't dispute this idea, I've been curious exactly how hard it really would be to open a car door under water. You have air pressure inside the car trying to escape, and although the door would be slow, it shouldn't cease to open. But I admit, that is one of the few car accident scenarios in which I have not trained. (We don't really have deep enough water in my covered towns to be an issue... although we did have a car in a swimming pool not too long ago, but that was a first for us... a drunk guy drove down someone's driveway instead of the on ramp to the highway... when we got there, he still couldn't figure out where the highway was... and what a swimming pool was doing blocking the road.) I do laugh at those emergency tools that are now being sold for car owners (that thing that looks like a mutant hammer, it has a center punch, a seat belt cutter, and I'm not sure what else on it). With all the accidents I've seen, any that a person would have a need to use such a tool, they are either not in a position to use the tool, or not in a condition to use the tool (kind of hard to cut your seat belt if you are unconscious with the dashboard in your lap) Personally, I see those as just another sucker product. My same feeling would apply to anyone carrying a center punch specifically to break the window if you drive into water. How many times in the past HAVE you driven into water, and when you did, what was your condition at the time, and where was the location of the punch relative to you, and how long would it take you to get to it vs how much time do you have to escape. All in all, its kind of silly, because the only time you will need it, you likely won't be able to use it. (I carry one not for my benefit, but for that of others... mine is in my med kit in my trunk, so I couldn't access it for myself even if I wanted to) -chris <http://www.mythtech.net>

2.5V Lithium "AA" sized batteries: Where to find?

James Fogg wrote: > It might not make a perfect solution, but you could > take 2 nicad cells (1.25V each) of similar diameter > and a shorter length (N size?) and place them in series > in shrink tubing to make a replacement cell. Yeah - I thought about that. Don't want to go there if I don't have to, though. (I did fail to mention in my original post that it requires 2 of these little beasts, thus making a 5V supply necessary.) > Also check out the oddball batteries available for > photo equipment. There's a lot of odd voltages in > that category, though you might have to slightly > modify the cell holder (widen it a bit). Yeah - thought about that, too. It is a fairly tight fit already, so widening the battery compartment doesn't look feasible. At this point, I'm thinking that if there isn't a direct replacement for this cell, I'll just pay the bucks to get it refurbished so it can use something more conveniently available. Appreciate the suggestions though!

11/45 progress

by jwest＠classiccmp.org

Based on the docs I got from Ashley I was able to re-arrange the memory section to be sane, cards were in the wrong slots. I was also able to get the jumpers set right on the G110 card. Now when I power up I can definitely read core correctly. There's a random assortment of data in sequential locations and returning to those same locations I always get the same value. That's a plus. However, I can't store anything. Anytime I store a new value in a location, that location gets all zeros. Moving to another location I get data, and moving back - zeros. So it appears to be challenged in writing, but not reading, memory. The plot thickens :) One thing I can't be sure of that the docs from Ashley don't say for sure is how to configure a less than full section of memory. I ASSumed you start >from right to left, but in the HP core section that would be a bad assumption. Humm... But if I had that wrong, I'm suprised I'd be able to consistently read memory locations. A different G231 and G110 and H214 didn't change the problem. Jay

PDP-11/23 ODT question

by wacarder＠usit.net

Yesterday I picked up a 6 ft rack loaded with a PDP-11/23, two RL02 drives, an RX02 drive, an RL02 pack, 3 boxes of RX02 floppies, and a bunch of cables. The rack was complete with side panels and top pink/purple panel. Today I figured how to get all 400+ pounds of it out of the back of my pickup truck and into my shop with just me and my wife. I then hooked it up to a VT100 and powered it on. It comes up with an octal address (177something) followed by the @ prompt. I'm used to unibus M9312 console emulator prompts and the 11/03 prompt where you can type in a two character code for a supported device and it will attempt to boot that device (ie DL, DX, etc). I'm going to search for the 11/23 ODT info, but in the meantime if someone can give me a quickie command set so I can try to boot off the RL02 or RX02 drives, I would greatly appreciate it. Is there a command to tell it to boot from the RL02 or RX02? Thanks in advance for any help that anyone can provide! Off to Google for 11/23 and ODT commands and to check Al's bitsavers. Ashley

Hmm, I have sent this to the list earlier. Perhaps it did not make it ... The M7800-YA is the current-loop only version. > Jay wrote about a DL11: > If I exam 776500, I get a 200, > but anytime I store a value and read it back, there's all > zero's in the data register. I will dig up my notes getting characters in and out a M7800 in my 11/35 resurrection using the front panel several years ago. This is also an advice: make notes of *everything* you do on a system, no matter how trivial at this time. Changing a wire, trying some toggle in tests on the console, behaviour, measured voltages on pins, etc. If problems occur later you can go back and do all tests from your notes. That's why I can write my tests with the M7800 when I get home (in a few hours from now). - Henk, PA8PDP. These are a few of my notes. Console board: 2 versions. M7800 and M7800-YA M7800: Xtal = 4608 kHz, has 1448/1449 jumpers: A3,A4,A5,A7,A9 open: A6,A8,A10 base address = 776500 baudrate = 1200 Bd. M7800-YA: Xtal = 1152 kHz, no 1448/1449 (20mA current loop only) jumpers: A0,A7 open: A4,A5,A6,A8,A9,A10 base address = 777560 (console) baudrate = 1200 Bd. console registers: RCSR 777560 RBUF 777562 XCSR 777564 XBUF 777566 Hit the key "1" of the keyboard If RCSR contains 0200 it means that a character is received. To check this: 1) set the SR to 777560. 2) press LOAD ADDRESS --> the ADDRESS LEDs show 777560 3) press EXAM 4) the DATA LEDs show 000200 RBUF should contain 061 (ASCII "1"). To check this: 1) set the SR to 777562. 2) press LOAD ADDRESS --> the ADDRESS LEDs show 777562 3) press EXAM 4) the DATA LEDs show 000061 Load 065 in XBUF --> the screen should show a "5". Operation: 1) set the SR to 777566. 2) press LOAD ADDRESS --> the ADDRESS LEDs show 777566 3) set the SR to 000065 4) press DEP Simple test of the CPU. 1) set the SR to 777570 (the switch register address). 2) press LOAD ADDRESS --> the ADDRESS LEDs show 777570 3) set the SR to 000777 (this is BRA . branch to myself) 4) press START The ADDRESS LEDs show 777572. CONSOLE LED is off, RUN, BUS, PROC LEDs are on. When you press HALT, CONSOLE LED goes on. - Henk, PA8PDP.

It's easy to add the parts; I've done it a couple of times. AFAIR, to get the full version, it's three RS232 chips, half a dozen resistors, and a capacitor. Maybe a diode. In case it helps, here's the pinout of the Berg connector, and the connections to make an RS232 cable and a 20mA loop cable. The "interlock" may require some explanation... The seril out from the UART is connected to both the RS232 and 20mA buffers, so when it transmits, it does so on both. However, you don't want both to be connected to the UART receiver at the same time, so you have to jumper *either* the 20mA receiver *or* the RS232 receiver to the UART, and this is what the "interlock" does: Numbers are DB25 pin numbers (for the BC05C) or Mate-N-Lok pin numbers (for 7008360): Berg pin Signal BC05C 7008360 A Ground 1 Prot.Ground (blue/wht) - ground B Ground 7 Signal Ground (brwn/wht) C 25 Force Busy (red/org) D 13 Secondary CTS (org/red) E TTL serial in - interlock in - interlock in F EIA serial out 2 Transmit Data (wht/blue) H 20mA interlock - interlock out J EIA serial in 3 Receive Data (org/wht) K +20mA serial in 7 + Rec.Data (green) L 24 External clk (brwn/red) M EIA interlock - interlock out N 15 serial clk xmit (grey/grn) P 19 Secondary RTS (lbue/blk) R 17 serial clk recv (grey) S -20mA serial in 3 - Rec.Data (red) T 5 Clear To Send (grn/wht) U V EIA RTS 4 Request To Send (wht/org) W 10 -ve power (wht/grey) X 22 Ring (blk/org) Y 9 +ve power (grey/wht) Z 6 Data Set Ready (wht/grn) AA +20mA serial out 5 + Trans.Data (white) BB 8 Data Carrier Detect (wht/brwn) CC DD EIA DTR 20 Data Terminal Ready (blk/blu) EE -20mA RDR Run 3 - Reader Run (black) FF 11 202 Secondary TD (blu/red) HH JJ 12 202 Secondary RD (red/blu) KK -20mA serial out 2 - Trans.Data (black) LL 14 EIA Secondary TD (grey/red) MM 21 Signal Quality (org/blk) NN 16 EIA Secondary RD (red/brwn) PP +20mA RDR Run 6 + Reader Run (black) RR 23 Signal Rate (grn/blk) SS TT +5V DC UU ground VV ground -- Pete Peter Turnbull Network Manager University of York

Amateur electronics questions, but almost on-topic

by Saquinn624＠aol.com

I have a couple of questions that I haven't been able to find in my books. (1) there has been much discussion in this list about capacitors failing. I recently had a cap on a QIC-24 drive fail with a bit of sound and fury (axial tantalum). Is there any way to test for this other than desoldering every cap (at least every electrolytic) and testing it on a cap meter? I don't want to fry my IMSAI, but there are a lot of caps in there and it would take forever... (2) (flame risk) My Tek 555 popped and blew a fuse when I had it plugged in last. I disassembled the PS and cleaned off the dust, and I want to test it by itself, but the power-on relay won't close. Any hints, or is this like amplifiers where the tubes need a load? - Scott Quinn

2.5V Lithium "AA" sized batteries: Where to find?

An old portable radio with a 90V battery comes to mind. My solution to the problem has been to use a regular battery that will fit in the space along with a buck or boost converter to generate the total voltage required. In your case I would use a regular alkaline AA in one compartment and a boost circuit in the other. Your use might not be quite as long as that of a Lithium, but alkalines are cheap.

9000 VAX wrote: > I guess the lab computer uses 5v CMOS devices and the > 2x2.5V battery let them skip the voltage regulator. That does have rhyme & reason to it -- yes. (And you are correct in that it takes 2 of these 2.5V lithium cells -- I failed to mention that in my original post.) I suppose it just couldn't have been foreseen by them that SAFT would discontinue manufacturing this particular battery at some point down the road. Still, though, wouldn't manufacturing a device which relies on a sole provider for its power cells raise a flag or two during the design process? It is not like these batteries are as common as dirt -- like your typical Duracell "AA". (Then again, I'm no hardware engineer, so I'm not familiar with how these decisions are made.)

Yup, that is exactly the kind of law it is. It really isn't enforced by itself (they don't round people up for owning lock picks), it is just used as an aid to arrest/detain someone that you have a really strong hunch is up to no good (and as a way to confiscate the tools from someone that you are sure plans to use them to commit a crime... this is done in inner city schools when kids pass thru metal detectors and are found to have various items that have perfectly legit uses... but you know the kid doesn't have it for one of those reasons... box cutters are the most common item) -chris <http://www.mythtech.net>

Age

by cheri-post＠web.de

Where are the young people on the list ? ;-) I'll turn 23 in a month and have been working on oldish and "cool" computers for approx. 7 years now. Started with a Philips P3200 (286, heavy stuff) which infected me with the bug... I can't talk of nostalgia as my machines are mostly from the time, I couldn't walk yet... DEC and CDC stuff, but also some SUNs from the time I started going to college. There's also stuff before I was born, like my PDP-8/a. It's funny to think about that. As adrian said, nostalgia from my time would be 386 and 486 and so on, which obviously aren't very interesting to investigate time on. Moreover, there's nothing you can repair on these things by yourself...

2.5V Lithium "AA" sized batteries: Where to find?

by elf＠ucsd.edu

[This post involves a hand held lab computer, of which this particular model was made/purchased about 15 years ago. Similar models have since been made, but without the problem I describe below.] I have a hand held lab computer (manufactured & purchased in 1990) which takes quite an unusual battery. The battery is the size of a regular "AA", but is 2.5V Lithium. The company who used to manufacture them (SAFT) no longer does so. The SAFT battery model # is "LCP 6". Picture of battery (and a regular "AA" for comparison): http://home.san.rr.com/instep/saft-lcp6.jpg (~42KB) Picture of lab computer: http://home.san.rr.com/instep/labpartner-front.jpg (~58KB) http://home.san.rr.com/instep/labpartner-back.jpg (~44KB) The company who made the lab computer still offers to refurbish the unit for a new (more readily available) lithium battery pack, but I want to avoid doing that if at all possible. They also don't have any suggestions as to where to find a 2.5V Lithium "AA" sized battery. AND -- I've Google'd high & low for an equivalent, but nothing pops up. So I've come here to ask: does anyone know if an equivalent battery exists? (And what's with the designer(s) decision to use such an obscure battery type?)

Also check out the oddball batteries available for photo equipment. There's a lot of odd voltages in that category, though you might have to slightly modify the cell holder (widen it a bit).

Yes, as the sole owner of Harhan Engineering Company I of course have total control of the Harhan.ORG and Harhan.COM domains, but why in the hell should I spend money on a backup server just because YOU decree so? Many many many original ARPANET sites did just fine with one single mail server for the organisation.

They're not expensive. I think I >paid under $15 for a reasonably nice set. Depending on where you are, owning a lock pick set may be illegal if you do not have a reason to own one. Last I knew, lock pick sets were illegal to own in NJ unless you are someone that has a "legal" use for one. Of course, since legal use isn't really defined, it leaves it pretty wide open. (It is also illegal to have a police scanner in your car, as well as carry a center punch... again, unless you have "legal" reasons for the above... of course, being a volunteer firefighter seems to get me past the legal requirements for all of the above... so naturally I own all the above... and carry a center punch in my car most all the time, as well as a lock pick set in my tool bag) Of course, IANAL, and I could be mistaken on the laws, or the exact forms of them... but it is a heads up for those that may be planning to purchase a lock pick set and run around with it in their back pocket... they should just verify that they are allowed to do such before they find themselves being accused of being a terrorist ;-) -chris <http://www.mythtech.net>

Cromemco Software - what to do with it?

Randy has suggested that Gaby might put it on her site, so that might be the answer. Maybe those of us who have some Cromemco S/W could get together here or off-list and compare who's got what. How about it Randy, you're doing such a fine job with the 8"/3.5" issue, feel like organizing something else? It's even relevant... ============== >> For that matter, is there any point?

And it only takes the space of a floppy disk (or no space at >all once it's been converted over to a modern hard disk). -------------------------- Well, that brings up the second point: if it's going to be archived on the 'net, in what format? As discussed elsewhere, PC images of Cromemco disks can be a problem because of their SD/DD mixed format. Ordinary CDOS files are less of a problem since they're 8.3 file names with no subdirectories; they can fairly easily be copied to a PC & ZIPped, and copied back to a CDOS disk. CROMIX & UNIX files are a little more problematic, because of the long file names & subdirectories. They can be TAR'd, but again, Cromemco being Cromemco, they used several incompatible TAR/TARZ80/FTAR formats. BTW, Cromix V31.58, for example, consists of 10 FTAR disks, although the Z80 versions are much smaller (2 disks) And of course there's still the problem of the mixed format boot disks. Any thoughts/a consensus? =============== >> So, any ideas what to do with it? (no obscene suggestions, please!) >Stick it up your hard drive? ------------------------------ Well, that's what I've been doing, but a good dump would be welcome :) Just need an appropriate site. =============== >> BTW, any news about what happened with Don Maslin's collection? >I'm wondering the same thing. ------------------------------ And what about Al Kossov's site? mike

>Guess I'll be hunting for a centre punch too ... You can get one of them at any decent tool dealer (or any non decent dealer that sells more then 4 plastic handled screwdrivers). A center punch's "true" purpose is to mark or ding items. ie: before drilling a hole in a metal sheet, you can use the center punch to ding the metal so the drill bit won't slide around as it gets started. They are really handy for breaking tempered glass cleanly.

Altair32 Emulator "Easter Egg" idea

by rcini＠optonline.net

All: I had an idea for an Easter Egg within the Altair32 Emulator. I remember a story that you could run a certain program on the Altair and hold an AM radio next to the Altair and you would hear music. IIRC, the song was "Daisy" as was played in 2001: A Space Odyssey. Does anyone (1) have this program in source and/or binary and (2) can someone make a high-quality WAV file of it for me (since I don't have an Altair)? I figure I could take some liberties within the emulator code to checksum/MD5 hash code loaded into the emulation space and if the music binary is loaded, it'll set a flag which when RUN is toggled, the WAV would play. Wadda 'ya think?

The idea is, a center punch is a rapid access tool for quietly and cleaning taking out a car window. So it becomes a B&E tool... much like your bolt cutters. (I actually carry a center punch in my car specificially TO break car windows... it is in my med kit that I carry in my trunk, and I've had to use it a few times when I've come across car accidents). But again, these things really boil down to can you convince the cop you have a valid reason for having them. If not, can you convince a judge. Anyone that has anything but an invalid reason, really shouldn't be worried. Those that plan to use them for illegal purposes tend to be pretty obvious (I don't know of anyone that has been harrassed over having the items EXCEPT for people that really were using them for nefarious reasons... I know of a few people that were questioned on them, and I know of a bunch of people that the items are ignored, because they have obvous legit reasons... just about all my friends have police scanners in their cars... but just about all my friends are in emergency services or law enforcement). -chris <http://www.mythtech.net>
