I've had lots of BNC's come off or go flaky after someone has pulled the cable, but I've only once had that happen to an RJ45. And I bet I can strip and crimp an RJ45 as fast as most people can crimp a BNC. The reason I like UTP is that if you once put in the infrastructure, you can use the structured wiring for lots of things. At work, we run Ethernet, RS232, telephones (POTS), ISDN, and video over Cat5/5e structured wiring. At home, I put in cables in lots of places and use it for serial, network, ISDN, and POTS. You do need to put enough cable in enough places, though. The other reason, of course, is that there are lots more LEDs to flash if you use a hub :-) -- Pete Peter Turnbull Dept. of Computer Science University of York

CP/M on the TI-99/4A

by dlw＠trailingedge.com

While cataloging this huge pile of TI and Amiga stuff I recently received, I took a moment to flip through some of the stacks of old magazines that were with it. I noticed a 5 & 10 meg hard drives for the TI. That's interesting I thought but what really caught my eye was the add from Morning Star Software for a CP/M processor board for the 99/4A. 5 MHz 8085, 64K RAM with 8K ROM. Has anyone ever seen one of these or any other coprocessor boards for the 99? I've always had a fascination with coprocessor cards for different systems. There was a 6809 card for the Apple II I would have killed for years ago. I'd assume these 99/4A CP/M boards would be few and far between. ----- David Williams - Computer Packrat dlw(a)trailingedge.com http://www.trailingedge.com

Imagine my surprise when a new cow-orker saw a 7935 at Wollongong in 1995 or so and said about the same thing. I had been thinking about the capacity: 404MB was pretty impressive for a washing-machine drive back in 1982. He was clearly thinking about the size, and comparing it with 540MB drives then popular in desktop Wintel PCs. -Frank McConnell

OT: Toshiba XXe Key Phone System Info?

by bill_r＠inetnebr.com

I guess it passes the 10-year rule, and it's got some CPUs in it (Z8xxx's) so maybe it's not as off-topic as I thought... ;-) We (my fellow techo-packrat housemate and myself) were recently given a Toshiba Strata XXe phone system and about 35 EKT-series phones by his company when they got a new system. It was working when disconnected, but we received no installation manuals - just phone user guides. It's all there, with (from what I've gathered from various web sites) an HCAU (CPU), an HCBU (aux CPU), two HCOU (central office) cards, an HINU (intercom) card, three HSTU-2 and one HSTU-5 (station cards), and an operator's console, but when they removed it, they just hacked off the 25-pair (or are the 50 pair?) cables from the HSTU cards, so I've got no way of knowing which pairs go to the phone jacks. Was wondering if anyone can point me to some information about this. Several hours of web searching has turned up some tantalizing hints, but nothing I want to risk blowing something up by trying. Any help would be very much appreciated. I found one company that will sell me a manual, but it's a weekend and this phone system _really_ wants to be hooked up! :-) Background info (if you're interested): We have half the stuff in the house automated with X-10 power control modules and the "Mister House" software using motion sensors, etc. to run lights, a 300 disc CD changer, software-based phone answering machine, etc. Mister House (www.misterhouse.net) is mostly a bunch of Perl scripts that can be made to do most anything with enough work. It also has voice I/O capability. I've got the whole place wired with ethernet, with laptops in most of the rooms. I've also got 4-pair CAT3 phone wire to each room. I'd like to use the XXe to run our phones, as well as letting "Mister House" use the hands-free intercom functions to talk to us around the house and/or receive commands from us. -Bill Richman (bill_r(a)inetnebr.com) Web Page: http://incolor.inetnebr.com/bill_r Home of the COSMAC Elf Microcomputer Simulator, Fun with Molten Metal, Orphaned Robots, and Technological Oddities.

I've already got fibre - a pair of StarLAN 10Base-T to 10Base-FL media converters (old and huge, but they work) and a pair of more modern 10Base-FL transceivers. I have a single fibre pair run up the walls >from the basement to the computer room on the second floor and my eventual goal is to lay fibre between my farmhouse and my quonset hut. I even have _one_ fiber long-haul modem - it looks like a DB25 - RJ11/RJ45 shell, but has one ST connector on it. Over a single fiber it multiplexes a full duplex 9600 baud signal and a second full duplex 1200 baud signal that can be used for flow control or an additional, low-speed channel. A friend of mine has its mate and if he ever finds it, I'll probably use it to monitor some console port on a PDP-11 in the quonset hut. Maybe I'll build a 20Ma to RS-232 converter and run an ASR-33 over it. :-) But I still want a piece of thicknet on my network, just for the amusement value. The fibre is for "gee whiz" value. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

All the earlier machines use one of several variants of a proprietary protocol/pinout, basically RS423 running at +/- 8 volts or more. >From the manual page: The pin assignments for the DIN-6 keyboard connector on the CPU board of some of the newer systems are shown in the following table: ___________________________________ |_____KEYBOARD_CABLE_PINOUT_______| |Pin | Signal | Description | |____|________|___________________| | 1 | KRCD | Keyboard Receive | | 2 | MRCD | Mouse Receive | | 3 | GND | Ground | | 4 | +8Vdc | Power | | 5 | KTXD | Keyboard Transmit | |_6__|_-8Vdc__|_Power_____________| For machines whose keyboards have the DIN-6 connector on the keyboard, as well as on the CPU, the pinout is shown in the following table.

The format used is one start bit followed by eight data bits, an odd parity bit and one stop bit, with one byte sent per key up or down transition. The MSB of the byte is a "0" for a downstroke and a "1" for an upstroke. Control bytes are sent to the keyboard with the same speed and format. The system software does all the processing needed to support functions such as capitalization, control characters, and numeric lock. Auto-repeat for a specified set of characters can be turned on or off by the system software by sending a control byte to the keyboard. When auto-repeat is enabled a pressed key will begin auto- repeating after 0.65 seconds and repeat 28 times per second. The keyboard initializes upon power-up. The configuration request control byte causes the keyboard to send a two-byte sequence to the system. The second byte contains the eight-bit value set on a DIP switch in the keyboard. All keyboard lights (if any; some newer systems have keyboards without user controllable lights) are controlled by the system software by sending control bytes to the keyboard to turn them on or off. Control bytes are also used for long and short beep control and key click disable. For the mouse: Signals: The serial data interface signal level is compatible with RS-423 which has roughly a 10V swing centered about ground. The idle state and true data bits for the interface are Mark level or -5V whereas false data bits and the start bit are spaces or +5V. The serial data is transmitted at 4800 baud with one start bit, eight data bits, and no parity. Protocol: The mouse provides a five-byte data block whenever there is a change of position or button state. The first byte is a sync byte which has its upper five bits set to 10000 and its lower three bits indicating the button states where a 0 indicates depression. The sync byte looks like this: 10000LMR. The next four bytes contain two difference updates of the mouse's change in position: X1, Y1, X2, and Y2. Positive values indicate movement to the right or upward. System software ignores bytes beyond the first five until reception of the next sync byte. -- Pete Peter Turnbull Dept. of Computer Science University of York

I'd better check on that one... Assuming the drive is a "1.2MB" 5.25", it will probably be capable of reading a 40-track disk, but writing is a different matter -- the track it will lay down will only be approximately half the width of the track a real 40-track drive will use. You will probably get usable results if you bulk-erase the media before writing, but it would be best to make a good copy on the RML drives as soon as you can transfer the disk. Look in the classiccmp archives for the full debate on 35/40/80 tracks, single/double/high density, and the rest :-) -- Pete Peter Turnbull Dept. of Computer Science University of York

I should have read that more carefully. If it's what I think you mean, it's a single/double density 80-track 5.25" in there. The same argument about reading/writing 40 tracks on an 80-track drive applies (just as for a 1.2MB "HD" drive) but you won't have to worry about speed (300/360 rpm) or (de)selecting HD. If you're using a PC, though, you may have to find a controller capable of single density. -- Pete Peter Turnbull Dept. of Computer Science University of York

Need SGI Classic Cmp Help

by LFessen106＠aol.com

I posted this earlier but never received any response or a return message myself so forgive me if this actually made it to the list and I am re-posting........ Just got 2 SGI Personal Iris's 4D/35's today (Thanks again Tom) and no KB, Mouse, monitor for either. Finally got dumb terminal hooked & working, and was pleased NOT to find boot password protection, HOWEVER.... 1 of them still has a working OS, and the other doesn't. I do not have any OS media for them at all, and the one that IS working has (Of Course) a root password which I do not have. What I really need here is a copy of the installation media here. Pleeeaaaasssee Contact me if you can assist in getting these systems running. I believe the 1 with the OS problem has the OS, but has no scsi disk label. Perhaps if someone were to have a root/boot disk they could copy off for me, I could get them working. I believe they run Iris 4.0.somthingorother. I am also in the market for an inexpensive KB and mouse combo for at least one of these. I also got an HP Apollo 9000/715. Seems to work fine but has abscent hdd for right now. I hooked it up using my other HP's HPIB KB/Mouse and monitor. Problem here is for some reason I can not get a serial console to work on this machine. Can't figure out what the heck I am doing wrong and was wondering if anyone here knew if I had to set that up in the HP's settings to get it to work as it doesn't seem to by default. (Before you ask, I tried both a null-modem and a regular cable on this on both the rs232 and parallel ports with no luck) Also will be looking for inexpensive HPIB KB/Mouse for this.. Thanks for any help you have to offer. -Linc Fessenden

Need SGI Classic Cmp Help

by CordaAJ＠nswc.navy.mil

I've played with a number of SGIs over my career, both at home and at work. I put up a web page a while ago with most of the info I've gleaned ("This Old SGI", http://www.geocities.com/SiliconValley/Pines/2258) Unfortunately, the web page is woefully out of date as I haven't had time to go back and restructure it the way I'd like. I am still quite interested in SGIs, but I've broadened my interests to include DEC (PDP-series) and SUN (both old and new) stuff as well. BTW, I agree with the approach below... although you can do quite a bit through the serial console, getting the graphics console up would be much better. The 4D/35 keyboard/mouse is proprietary, but should be available from places like www.reputable.com, www.mce.com and www.mashek.com (and many others who's name escape me at just this moment) The mouse might be fudged using an old Sun mouse and some mods, but I would still recommend getting a "real" SGI mouse as the modified sun mouse doesn't work as well as the real SGI version. Just as in the comments below, I recommend going with Irix 5.3. It will run reasonably on this machine (with sufficient memory), and provide quite a bit of functionality. One thing I _strongly_ recommend... Use an air gun (or canned air) to blow out the dust throughout the entire case (including air plenums, power supply and e-module(where the circuit cards are)). I disassembled mine (including removing the power supply and popping it cover) to clean it. This critter acts just like a vacuum cleaner and will suck dust and dirt up from the bottom airgrate faster than you can imagine. At work, we mounted these things on small (6") pedestals to try to cut down the amount of internal dust they sucked up. I imagine the accumulated dust might contribute to the fire problems mentioned below. BTW, as far a CDROMS go, SGI used Toshibas (I think the models were 3401 or 3501)for quite a while. The important thing is to make certain that they are jumpered for 512K bytes/sector. I believe some of the older Texel/ Plextors will work also. The recommended SCSI ID for SGI CDROMs is ID 4. Another Gotcha... SGI uses scsi ID 0 for it's controller ID, so you should jumper all your scsi drives/devices for id 1-7. ...Good Luck!... -al- -acorda(a)1bigred.com (also acorda(a)geocities.com) > -----Original Message----- > From: Mark Green [mailto:mark@cs.ualberta.ca] > Sent: Monday, November 20, 2000 2:47 PM > To: classiccmp(a)classiccmp.org > Subject: Re: Need SGI Classic Cmp Help > > > > I posted this earlier but never received any response or a > return message > > myself so forgive me if this actually made it to the list and I am > > re-posting........ > > I hadn't seen it either, otherwise I would have replied. > > > > > Just got 2 SGI Personal Iris's 4D/35's today (Thanks again > Tom) and no KB, > > Mouse, monitor for either.

Other CBM trivia?

by jjackson＠salsa-digital.com

I also have a couple of the CBM books on PET BASIC that were printed very early on. I'm doing this from memory, but I believe that one of the authors was Adam Osborne (of the same Osborne computer fame?). I also have a very early book by him about computers and computing in general. It was used as a 'textbook' for a class I took at a junior college here called 'Microcomputer Kit Building'. All of the students were required to start assembling a computer - some even completed their kits. I was about middle-way through with my SwTPC 6800 kit at the time. It was a really cool class - I didn't understand very much of it - way over my head at the time. <grin> Regards, James Jackson

Commodore Series B-128

by jjackson＠salsa-digital.com

All this talk recently, reminds me of the computer that I just had to have... the B-128. I always liked its' looks, and finally found one many moons ago, so I bought it. It turns out to be a really neat computer... too bad C= didn't promote it. (I think that they must've had many new ideas at the time, and weren't sure which ones to pursue.) Anyway, I linked it to an 8050 floppy drive, and played with it for a bit. I soon grew tired of it (well, not really - just needed the space), and sold it to a fella locally. He probably still has it in storage, too. I had invested much in this computer - getting the schematics for it, and other documentation. It was sort of a cross between a C-64 and PET80xx(?) seies computer. Was real fast at 2-Mhz, and would run many of the C-64 programs straight out - provided they didn't get too graphics intensive. I used to do timings between the B-128 and my ol' C-64. Ahhh... those were the days. Regards, James Jackson

AppleTalk over NT

by RCini＠congressfinancial.com

Doug: I got the Mac services working. Apparently it wasn't a problem on the Mac side. The one item that the NT manual left out is that the directory in which the UAM volume resides has to be shared and have the permissions set. I found a Web page dealing with this setup. So, when I shared the directory on the NT Server, the directory was visible by the Mac client. All machines are on the same subnet. The NT Services for Mac is set with routing enabled because there are no other Mac servers on the net. This is per the SFM docs. Thoughts? Now, I need to get printing working. I have a PS laser printer connected to the server. Is shared printing a possiblity? >> Re-reading the NT docs, I'm supposed to see the >>AppleShare icon in the >> Chooser, which I don't. I only see AppleTalk. Hmmm... >>??? I was having all sorts of problems at this point. In the MacTCP control panel, I would only have LocalTalk and no Ethernet. I rebooted and reinstalled from the Network Installer disk and then the Asante disk. Then, EtherTalk appeared. Originally, in the Chooser, when I selected AppleShare, no zones showed-up (which was fixed by the above). I've been using TransMac to move disk images to the ci. Moving them across the network doesn't work because the type/creator information is not moved. As far as I can tell, neither TransMac or HFV work with remote (network) drives, so I can't get their translation benefits. Also, using a null-modem setup doesn't transfer the credtor information. So, the transferred programs are not usable. So, I've been relying on TransMac 4.1c which works well. I'm making images of System 7.5.3 plus the update. I also want to get Web access on that machine. I've got a simple browser, an email and telnet program moved over, but I have to work on the broadband access. I have a cable modem connected to a NAT firewall. All internal machines are on the same subnet with the firewall (192.168.1.x). Could you make me a BinHex or SEA image of the 3.6.4 client disk? Thanks. Rich ========================== Richard A.

Hmmm... ??? I don't see AppleTalk in the Chooser; I see AppleTalk in Control Panel. In Chooser, I see icons for each type of printer driver I'm using, and I also see the AppleShare icon. However, none of our legacy Macs are that old; System 7.5.5 is the oldest in use, OS 8.1 the newest. ISTR that AppleShare Client 3.6.4 is the oldest version of the client in use here. > I configured the MacTCP to point to my firewall for Internet access. Maybe > this should point to the NT Server?

NT Services for Macintosh doesn't have the capability introduced in the AppleShare Fileserver IP 5.0 that permits clients to make connections over TCP/IP; and the earliest AppleShare Client that supports the TCP/IP connections is 3.6.4 (we had to make that the baseline while we were still running a Mac fileserver). If you're trying to access the NT Server across anything other than the LAN that the NT Server's NIC is connected to, you're out of luck. No bridges, routers, etc. Additionally, you have to create a directory somewhere, share it for access by Windows clients, then use NT File Mangler to create a Mac Volume from that shared directory before the macs can see them. But it sounds like you're having trouble before you get that far. Hope some of this helps... -dq

I have a dual 3 1/2" + 5 1/4" drive, but I can maybe I can use one of the drives out of the RM if it doesn't do 360K correctly? I'd better check on that one...

HP Questions

by jate＠uwasa.fi

Hello! I have a couple of HP related questions. I started thinking about these while I was scanning all the 9000/500 docs that I have and in HP 27110B HP-IB card manuals I saw a sentence similar to this "..supported in all HP computers with CIO bus..". 1. Which machines had the CIO bus ? I know of 9K/550, 520 and at least some version of the bus in some 800-series machines. 2. I know about 200/300/400/500/700/800-series but what is 9000/600 which I've seen in a couple of manuals. 3. Is the HP 7970 tape drive vacuum column or one of these newer streaming devices (like the 7974A). And extra bonus-points for the person who recognizes the app in the cover of the HP 9000 550 manual at http://www.tec.puv.fi/~s99137/kuvat/cover.gif And a couple of low-quality "recognize the peripheral"-pics at: http://www.tec.puv.fi/~s99137/kuvat/uudet/ (none of those are mine, btw.) Particularly cipher.jpg, HP2000[12].jpg, nauha.jpg, hp3kcons.jpg. TIA, -- Jarkko Teppo | Lahjoita HP 7933:n levypakka hyv??n kotiin! jate(a)uwasa.fi | :wq! |

VMS BBS network

On November 18, Billy D'Augustine wrote: > > Also most importantly is anyone > > seriously interested in this? > > I'd be interested! You know, call me crazy, but I think I'm interested as well. Yeah. I, too, miss the dialup BBS days, and it'd be neat to do something even remotely like that again. I ran the Mercerville RCP/M system for about three years up near Trenton, NJ, when I was in high school...I shut it down in 1987 in favor of putting my pdp11/34a (running RSTS/E) on a dialup line for my friends to hack on. My favorite part of the whole old BBS scene were "storyboards". Anyone remember those? Of course, the concept could be approximated with netnews, but it's just not the same. Having a specific interface designed for that sort of writing...chapter navigation, stuff like that...is really, really nice. I tried to bring up another BBS many years ago (1990 or so) on an AT&T 7300 (UnixPC, 10MHz 68010, 512K, SysVr2). I ran a program called "unaxcess" which I really liked. Has anyone here ever seen it? -Dave McGuire

Women and Classiccmp

Was DEC a particularly liberal company when it came to hiring >able women? This might be the beginning of a nice lesson in company >history. . Briefly, DEC and a lot of determination. I was in engineering for over ten years before that. DEC was a very good place to work. As was NEC (when they were in Wellesly and Natick). Some other places I have less fond thoughts of. The determination part is not new to anyone here, you find something interesting and you do it. That do it part is despite naysayers or other attempts to discourage. Allison Allison

intro and RML380Z

by kebabthesheep＠yahoo.com

Hi, as is customary for many a mailing list, I should introduce myself first. My name is David Rowntree, I am a systems engineer, working for Philips Semiconductors, based in Southampton, UK. My interests centre mainly on UNIX systems, but I like anything computational and old. I recently found my Research Machines 380Z in a pile of junk, and got interested in it again. For those who don't know, its a Z80 based CP/M machine sold in the UK, mainly to schools and other educational establishments. Mine came from Imperial College, London, where I studied for my Meng in Electronic engineering. The box in question is a RML-380Z-D model, with dual 5 1/4" drives, and I think, 32K RAM. It has two video boards (I believe this is the hires option) and an additional ram board(cpu board with most bits removed) an analog i/o card, and seems to have firmware 'COS4.2A' The date of the box is '83, and is complete with its keyboard, and even the dust cover! Unfortunantly - NO SOFTWARE AT ALL. Not even cp/m :( I know next to nothing about this box, so my query: Does anybody have the system disks? How about documentation of the firmware? I've found various bits of cp/m source, but nothing specific to the 380z. I believe it ran cpm2. One other point - I believe you hit 'b' to bootstrap the floppy - when I do this there is NO disk activity (even with a floppy in the drive) I've tried both drives, and both cable positions. The drive psu gives stable volts, so that's not the problem. I'm sure it should do something! There is an LED on the floppy controller, it flashes with a kind of 'heart beat' pattern i.e. Flash-flash--pause--flash-flash--pause etc. Anybody know if this is normal? You guys are possibly my last hope - I've spent a total of over 20 hours scouring the web for info, and have come up with very little. I'd like to get as much on this box as possible, for preservation reasons - and so I can build a website about it. Many thanks in advance for anybody who can help me out! Dave. __________________________________________________ Do You Yahoo!? Yahoo! Calendar - Get organized for the holidays! http://calendar.yahoo.com/

Resistance is useless!

by Mzthompson＠aol.com

Dear Mr. 9000, HAL, you seem to be using the wrong AlGorerhythmn. You say that 'Resistance is useless', when it should be 'Resistance Is Futile'. As in: "We are Microsoft. Resistance Is Futile. You Will Be Assimilated." Unless of course there is some sort of mental aberration, as in: "I am Dyslexia of Borg, fusistance is retile. Your ass will be laminated." I would ask that you incorporate the following lines of program code so that things are done right in 2004. Can we count them with our nose? Can we count them with our toes? Should we count them with a band? Should we count them all by hand? If I do not like the count, I will simply throw them out! I will not let this vote count stand I do not like them, AL GORE I am! Can we change these numbers here? Can we change them, calm my fears? What do you mean, Dubya has won? This is not fair, this is not fun Let's count them upside down this time Let's count until the state is mine! I will not let this VOTE count stand! I do not like it, AL GORE I am! I'm really ticked, I'm in a snit! You have not heard the last of it! I'll count the ballots one by one And hold each one up to the sun! I'll count, recount, and count some more! You'll grow to hate this little chore But I will not, cannot let this vote count stand! I do not like it, AL GORE I am! I won't leave office, I'm stayin' here! I've glued my desk chair to my rear! Tipper, Hillary, and Bubba too, All telling me that I should sue! We find the Electoral College vile! RECOUNT the votes until I smile! We do not want this vote to stand! We do not like it, AL GORE I am! How shall we count this ballot box? Let's count it standing in our socks! Shall we count this one in a tree? And who shall count it, you or me? We cannot, cannot count enough! We must not stop, we must be tough! I do not want this vote to stand! I do not like it, AL GORE I am! What's that? What? What are you trying to say? You think the current count should stay? You do not like my counting scheme? It makes you tense, gives you bad dreams? Foolish people, you're wrong you'll see! Your only care should be for me! I Will not let this vote count stand! I do not like it, and AL GORE I am! Sincerely, G@K

The question is, how secure is DECnet over IP? Can >you send it via an encrypted link? I've not read up on it yet. Extremely secure if IP is done right. DECnet is good in itself. Doing it as wrapped decnet would be hard for outsiders to crack unless they knew it was DECNET inside. It's basically VPN. FYI, back in the old days (early 90s) DECNET was used to wrap appletalk and Novell so it could be run over wans (DECNET is routable). Allison

HP 9815A question

by ss＠allegro.com

Hi, I recently received an HP 9815A ... working, except that the display is dead. (I.e., I can enter numbers, do calculations, and print the results on the integral printer.) Does anyone have experience with this machine? The display (about 5 or 6" wide, 1" tall) is a Burroughs Panaplex II, with the following markings: Kr 85 BR 16252 An odd little pointed glass cone juts out of the back of the panel, in the center. thanks, Stan Stan Sieler sieler(a)allegro.com www.allegro.com/sieler/wanted/index.html www.allegro.com/sieler

New IIci

by RCini＠congressfinancial.com

Hello, all: Yesterday, I received my first modern Mac, a IIci. It comes with 8mb of RAM an Apple TokenRing card and the Workstation Display card (Apple# 630-4179). The monitor is the 12" hi-rez monitor. It runs System 7.0.1. I have a few random questions... The workstation display card has a 13W3 connector on it. I understand that if you use an external display adapter, you can reclaim some system RAM by disabling the built-in video. Is this true? If so, How can I connect the 13W3 to the Hi-Rez monitor which has a DB15 connector? I looked in some catalogs, but there doesn't seem to be an adapter made for this. The TokenRing card is useless to me, so it's up for trade. I installed an Asante ethernet card, but I still have to install the driver for the card, which I downloaded to my PC. I'm going to use TransMac or workalike to transfer to 1.4m diskette. What is the best internet browser for this configuration? I have a cable modem connection, so dial-up is no issue. Like I said, it has 8mb of RAM. I have a few random 30-pin PC SIMMs laying around. Can I typically use these? What should I watch for? The ci also has an X-eyes-like application that shows-up on the menu bar. I looked in the usual places for where this could be installed, but I can't seem to find the file. There's also no configuration menu to disable it. If I can't find it, no big deal, but I'd like to disable it if I can. Again, the token ring card is up for trade. If anyone's interested, contact me off-line. Thanks again. Rich ========================== Richard A. Cini, Jr. Congress Financial Corporation 1133 Avenue of the Americas 30th Floor New York, NY 10036 (212) 545-4402 (212) 840-6259 (facsimile)
