I kind of half asked this once before, but it was stuck in on another thread, so I think it was overlooked. Does anyone have info on how to use the I-Modem protocol for data transfers? (that's Eye-Modem). All I have been able to find is that it is a protocol designed for long distance, slow connections. So it sends a packet, and doesn't wait for a check. Rather it just sends all packets, and at the end, the recipient sends back a list of bad packets to be resent. The idea is, it will be faster when sent over a high latency connection. I *think* the protocol was created by John Friel. I base that off the little info I was able to find thru multiple different online searches (google being the most useful). What I am looking for is the specs needed to write an implimentation of it. I have a system that can only send files via i-modem, and I want to write a new program to talk to the server. Right now I use Procomm Plus 1.1b since it is the only application that I have found that supports imodem. I would like to write a custom front end to the system, so I can make access safer, easier, and more automated. If anyone has specs, or source code for imodem they can send me, it woud be very helpful. Thanks -chris <http://www.mythtech.net>

By 1987 the microVAX had been around for a while, the midrange VAX was 4x-8x faster than the 780 and easily 1/3 the size! Cromemco was pretty neat but first, fastest not hardly. Allison

Hi: I downloaded a few very old programs from the 80's from an on-line (probably illegal) version of the DDJ CD (version 7).

Dick; Sorry about all the Apple brotherhood jumping on you with both feet. Having been beat up for so long, we're overly sensitive :-) Forgive us our CPU. We know not what we do.

Sun / CalComp Printer networking problems (was: Thick Ethernet/Sun networking problems)

by Arno_1983＠gmx.de

Hello Pete, at first: Is it okay to continue our mailing this way (directly mailing the messages, only CCing to Classiccmp.org? It's because I'm on the Digest and it has been arriving at about 4 P.M. local time the last few days, which is too late for me to stay in school and pick it up the same day (alas, don't have Internet at home yet). >Ah. It's quite likely there are some links on the card which have to be >set one way to use the 10baseT port, and the other way to use the >transceiver... Look for a set of 6 links. No, nothing on that board. There are only two 2pin jumpers, one for printing out the adapter's status page and one for resetting the NOVRAM contents to the factory defaults. I think I've already seen what you mean on other network devices (six or so 3-pin jumpers, the movable parts sometimes joined in a blue plastic tray). >>But no signs of overheating etc. on the PCB... OK, I admit that was only for VISIBLE SIGNS. The LM2577-T12 (switching voltage regulator in TO-220 package) next to the AUI port becomes TERRIBLY hot even after < 10 minutes of running the printer. I assume it's used to generate the voltage the Transceiver uses? But the power light (on the transceiver) is on as long as the printer is... And even worse...the DATA LED does no longer blink when there's traffic on the Ethernet... OK, I hope that helps Arno Kletzander Arno_1983(a)gmx.de -- GMX - Die Kommunikationsplattform im Internet. http://www.gmx.net

Seems odd if the DATA LED blinks when there's traffic, though. I >wonder what that LINK LED really is for? According to the Ethernet Hardware Manual (we finally got a copy from somebody who also still uses such stuff...YEAH!), the LINK LED will only illuminate if there is an active connection via the 10baseT network interface, NOT when using the AUI port. BTW, this is the same way my PC's network interface uses it. Yesterday, I went and borrowed a cross-over TP cable from the teacher who does all the network stuff at our school. Connected it between my PC and the printer, let 'em power up...and pinging and telnetting both worked! I verified (by connecting the PC to the Transceiver the printer used WITH the drop cable the printer used, then telnetting to one of the SUNs) that transceiver and drop cable are okay. So I think the fault is on the AUI port of the printer's network card. But no signs of overheating etc. on the PCB... OK, so far for now...

Reconstructing "King's Quest"

by spectre＠stockholm.ptloma.edu

Now that I have my utility 486 up and running with a PC 5.25" drive, there are some projects to be commenced. One of them is to get King's Quest transferred over to the PCjr, since KQ1 only plays music through the PCjr. (Or so they say.) PC Gamer published the original KQ1 on one of their cover discs about a year ago, which I have, and was able to unpack it and it's sitting on the utility 486. The problem is that the total size of the files is ~400K, and I'm willing to bet that the PCjr's floppy does not support HD 5.25" (right now I'm about 100 miles away from it, or else I'd test it :-). If it does do HD floppies, that solves the entire problem. Assuming it does not, what is the layout of files on the various KQ floppies? Can someone list the files on their KQ1 disk(s)? -- ----------------------------- personal page: http://www.armory.com/~spectre/ -- Cameron Kaiser, Point Loma Nazarene University * ckaiser(a)stockholm.ptloma.edu -- Let us live!

Refilling Toner Carts (was RE: Rubber Restorer...)

Rumor has it that UberTechnoid(a)home.com may have mentioned these words: >Having been inside thousands of laser, led, and Inkjet printers in my >time, I'd have to agree with HP. As much as I hate "me too" posts... "Me Too!" >Third-party recycled toner carts can cause an ungodly mess a tech is gonna >have to clean up. Inkjet refill kits can have the same effect (but >gooeyer). Or worse. There are some inkjet printers out there that have an "overflow" valve & tiny reservoir that will take up excess ink - if you refill these cartridges, once that overflow reservoir fills you can actually ruin your printer! Granted, there are some inkjet printers that IMHO should have never seen the light of day... but I'll not get into that. :-) >For those on the list, you know what you are doing and know what you are >getting into, but PLEASE tell your customers/clients to buy original toner >carts or carts from a known maker (such as Xerox tonor carts for hp >printers).

Apple Floppy Drives (was: More Apple Pimpers)

by ajp166＠bellatlantic.net

RE: apple II I've worked around and with them. Never serious 6502 programming but used apps on them like UCSD pascal. The disks worked ok compared to my NS* {NS* disk controllers are reliable} and yes they were sensitive only to the extent that an unshielded 34pins cable didn't like to be near some monitors. The tubes in metal cases were ok but some of the plastic cased ones tended to radiate noise that the cables seemed to find. It's beauty was the basic logic was simple as were the drive hardware and that helped it work better than most. Some of the better floppy systems of the time where neither simple nor cheap. RE: trs80 >TRS-80 drives? I have a beautiful Model 1 setup. But talk about trashing disks! And slow! Slow was running the z80 at 1.7mhznot the disks fault though the step rates were really slow even for sa400s!.. See above and yep the tube was plastic cased and worse hot chassis! Grounding was poor on the drives, their internal regulators were at limits current wise plus the data separator in the EI was very poor. Not to worry though, as most tended to crash from the sloppy and noisy console to EI interface. >What about the single board CP/M machines? I have them too. The disk drives on the >Osborne were, based on extensive experience, the least reliable ever made. If one >drive could read what another had written, it was a gift from God. And with the double density upgrade, it was much worse. That was the drives and I always thought the SA400 series to be really poor even though my NS* had three of them. TM100s were not much better! Also there was some really bad media based on some of the media failures I've had over the years. The SA400 was the slowest, most unreliable floppy of the time, it made everything it was attached to look bad. The worst part is many vendors of early 5.25 drives had their own version of worst at one point or another. >And even later, how about the "ingenious" DEC double disk-munching drives, that couldn't >format disks? The drives could but the controller didn't, therein lies the difference. The RX02 was old when the 1771 FDC was young so comments based on post 1980 tech are not reflective of then(pre 1980s). I'd call the RX01/2 the 1970s version of an IDE floppy as it was smart and executed commands that were higher level than even the 1771, mostly due to the microcoded controller. The RX01/2 were reliable enough though the RX50 was pretty poor. In my book after the RX02 the next useable floppy from DEC was the RX33 (teac FD-55GFR). The commie controllers were a good idea that suffered from poor implementation. they were fast in themselves but the serial link was limited. Allison

Goodwill Computer Store Austin, TX

by jss＠subatomix.com

I met up with Bill Bradford today in Austin. One of our activities was to visit the Goodwill computer store there (you know, the one with the museum in the back). Well, it turns out that the general public is no longer allowed to see the museum pieces (either that or the museum pieces are no longer there), and it's all due to some freaks who broke in and stole -- guess what -- A FREAKING *NINTENDO* *SUPER* *FAMICOM*! -- Jeffrey S.

ISIS & CP/M for MDS 225 series3

by ajp166＠bellatlantic.net

Standard CP/M on 8" is the right bios but.... The right media as the MDS controller was SD/D2... single density(normal ibm 128 byte sectors) and D2 was double density by m2fm and incompatable with everything except Intel. So you need another working intel box user.

Megan; Please - oh please - round up all your female friends and get them on this list. One of the best firmware programmers I ever knew was a lady named Pat Daniels that worked with me in the late 70's and early 80's. We developed Z80 firmware for custom multiubus boards and were often forced to debug the hardware for the designers using Biomation and HP logic analyzers. I know she would claim that was the most fun she ever had hacking code.

Dick; Without getting too far into religious issues, its been my experience that Macs have consistently supplied a good computing environment for me since 1984. My company uses both Macs and the latest Dell and Compaq PCs, and I lost count of the times our Wintel people have replaced hard disks and reloaded Windows. I have yet to see any of our Macs fail, and we have owned one of virtually every model. I own a G4 with a Cinema display that I wouldn't trade for any Wintel box made. What has impressed me is the level of integration between hardware and software - natural since they own them both and can ensure a high level of compatibility. This lends itself quite well to adding new peripherals and other devices and have them working quickly and without a hitch. I recognize that Apple lost the OS wars. The reasons are numerous, but one of the main ones stems from the corporate mentality of the early 80's when you could never get fired for buying IBM. Hence, truckloads of IBM PC's with Lotus 123 appeared on managers desks. Marketing and sales liked Apple because their desktop publishing capabilities were far and away better than Windows toward the late 80's, but these people were in the minority, and as Windows came along, there became less and less reason to go Apple, from management's point of view. And once Apple was forced from corporate desktops, they were relegated to a niche market, where they will remain. I am productive on my Mac. You are productive on your PC. I'm sure both are terrific matches for their respective users. And as all of us on this list can attest, there have been numerous computers and OS's that, while they may be terrific machines, fell by the wayside for one reason or the other. And you never know. Linux may just be eating Microsoft's lunch by 2005 and those Wintel boxes may start to look nostalgic :-) Craig Landrum Chief Technical Officer Mindwrap, Inc > Date: Sun, 4 Nov 2001 20:07:04 -0700 > From: "Richard Erlacher" <edick(a)idcomm.com> > Subject: Re: hard-sector 5 1/4 disk > > Well, I'd have to say that, since the performance and reliability haven't > improved since back in the '80's, the Apple was not designed for serious use, > but rather for use by those who didn't value and trust computers enough to make > the investment in one that warranted the value and trust.

OS9 or Flex09 on 8" disk needed

by jhellige＠earthlink.net

Does anyone have OS9 or Flex09, preferably for the SWTPc, on 8" floppy or a means of making one on 8" floppy? I've finally gotten a nice 8" cabinet with a pair of Siemens' 800-2 drives as well as a bare pair of Shugart 851's and would like to give them a whirl with the DMF2 floppy controller installed in my S/09. This was it's last configuration, running OS9 with the Microware support ROMs on the MP-09A. I could even provide the 8" disks if someone was willing to make them.

Micro PDP 11/73

by lemay＠cs.umn.edu

Well, I decided to take the day off, so what should happen but that I get email from work teling me that someone has left a PDP 8/75 in a desk with floppy drives on the loading dock (which is very very close to my office...). So, I come in, and of course its not the pdp 8/a i'm expecting, no... Its a Micro PDP 11/73 with a couple of other rack mounted things that i'm guessing are modems or some such (non DEC). Anyways, I take the computer and rack mounting parts, but now i'm full of questions. For one thing, whats the proper way to get to the cards? It looks like i may have to take apart the back end of this thing, which contains about 9 male DB25 connectors and a 2 digit LED numerical display... So far, I can tell I have the KDJ11-B CPU board, which is quad height unlike the A version which the web tells me was dual height. I can see there are cards in the upper 4 slots of the bus, and that there may be a total of 8 slots. Anyways, i'm afraid i'm not knowledgeable on this 'modern' DEC stuff, so any help, like sugestions on the proper way to open the back of this thing, would be appreciated. -Lawrence LeMay

OT: Chemistry Sets (was RE: Rubber Restorer...)

Yeah, chem sets are pretty tame now :( -- can't do many real reactions other than make C02 from bicarb. My father was a chemist and added many chemicals to the Gilbert set we had (more than 10 years old, so somewhat on topic). I do shudder a bit to think of some of things we did, though, like playing with big globs of mercury in our hands. BTW, water glass is Sodium Silicate, not phenothalien. And carbon tet, not benzene, was dry cleaning fluid. As kids, my brothers and I used carbon tet in killing jars to gas butterflys for our collection. It is banned in most places now, and benzene use is severely restricted, as it too is a strong carcinogen and bad for your internal organs. -----Original Message----- From: Russ Blakeman [mailto:rhblakeman@kih.net] Sent: Tuesday, November 06, 2001 8:14 AM To: classiccmp(a)classiccmp.org Subject: RE: Rubber Restorer...

One-off vs. One-of (was Re: CPU design at the gate level)

by mmcfadden＠cmh.edu

Of the instances I know of most one-off's never were from an assembly line just attempts to change or demonstrate a concept. The R&D group I worked with always was producing prototypes and proof-of-concept devices. The proof-of-concept units were mostly breadboard style with wires and components in any order and not in any form factor. A prototype was then constructed, sometimes milled of plastic or aluminum, it mimicked the final units appearance. The prototypes went through several interations to make a manufacturable model that could be made within the cost desired. Then the manufacturing engineers came in and tried to make it repairable and assembleable. The whole process is currently much compressed with the manufacturing engineers included from the beginning to reduce cost and time-to-market. Our group made medical microbiology devices designed by aerospace engineers, way overengineered, and with more feedback sensors than you could believe. We started out with PDP 11/05 , then migrated to 11/04. They eventually wanted to replace our PDP-11/04, with VT52, based computer systems with homegrown computer, terminal, and printer. Never implemented. Mike mmcfadden(a)cmh.edu

CPU design at the gate level

Tony, Faster as in is sub 150ns are fairly common and cheap. Whats problemtic is that the ALU must do about 8-16 different operations so that would be at least a 512kN part or larger. Also 74(ALS,F,AS)381 in the 16 bit or wider range would be hard pressed to do better than 50ns even with carry lookahead.

This really is a tough one- it's possible some of the stand-alone transfer protocol modules might have implemented it, but didn't include any info in the docs... as a search yielded no more than you found. Two thoughts: The WildCat BBS has (IIRC) the IMODEM protocol; contact the WildCat prople and ask them for just that single module (they want about $800 for the BBS source code). Secondly... reverse engineering by setting up a second PC running any terminal emulator, try sending a file from the IMODEM-only device, surely it will respond to ACK/NAK... try NAKing some packets, ACK some others, dump the result, start hacking... Be sure to filter out the ACKs/NAKs you're sending from the dump, no need to confuse yourself... hth, -dq

Zenith Data Systems Z-386 SX/20 Free in NJ

by mythtech＠Mac.com

If anyone wants it, I have a Zenith Data Systems Z-386 SX/20 available for free in Ridgewood, New Jersey. You have to come pick it up (or offer me enough to make it worth my time to pack it for shipping). It appears to work just fine. It is missing one of the two 3.5" drive slot covers. It is currently configured with a 40mb HD, a 360k 5.25" floppy, 2mb of RAM, and CGA video. I can't figure out how to change the setup, so it is useless to me (if I can't at least get it to accept a 3.5" drive, I can't use it). It is up for grabs, but like I said, I don't want to take the time to pack it up unless I am getting money or something good in trade. It can be picked up in Ridgewood, NJ (North East NJ). I am only going to keep it for a day or two to see if it gets claimed, after that, there won't be enough left of it to claim. I can store it longer for someone as long as you tell me roughly when you will pick it up. -chris <http://www.mythtech.net>

value of scrap

by dec.parts＠verizon.net

Hello John and others, > I think I could pay scrap (.gt. free ) value. The scrap from commercial systems is actually valuable. Scrappers can get up to $2.00 per pound for it. I had 8 racks of cards ( non-DEC very proprietary stuff ) that didn't seem to want to sell individually, so I sold to a scrapper. That batch totaled 880 pounds, and I got $660.00 ( $.75 per pound ) and that scrapper wouldn't have been buying it unless he was making good money on it too. It just about paid for the 16' beavertail flatbed trailer I bought from the same fellow. So when Heinz says ... > It sucks that these people would rather scrap out a machine > than let a collector have it for free. It translates to ...

Rubber Restorer...

by technos＠nerdland.org

I still see it sold under the brand name "Carbochlor" as a industrial grease thinner/solvent. Dry cleaners still use it too. Any decent hardware will stock it. On a off note, it's fun to add to a styrofoam cup of coffee.. Scent fades and the cup dissolves to a rubbery shell. Pick up the cup, you're stuck with a handful of goop and coffee. Oh, and don't get it on your hands. Not only is it a carcinogen, you'll get a benzene buzz from even small splashes. And SpotShot isn't anything like Carbona.

classiccmp-digest V1 #766

by clandrum＠monumental.com

Phil and Mac junkies; The MicronEye was in production for a very short time as far as I know. It claimed to use a "video RAM" - a light sensitive RAM that they claim they discovered by accident. The MicronEye was a bit larger than a 35MM film cannister and had a focusable lens and iris at one end and a ribbon cable coming out the other end, which plugged into a tan flat controller box. The controller box connected to the printer or modem serial port on the Mac. The camera came with a small foot-high tripod so you could aim it and a diskette with the application sofware on it. The software let you take black and white pictures and save them as either PICT files or MacPaint files. If I recall correctly, the picture that it took was half of an original Mac size screen and was definitely black and white only. Also FYI - the MicronEye was released and available when the original 128K Mac was released, which was when I got mine. I still have it all along with the software. It all worked last time I fired it up. I also have an interesting game call Chipwits for the 128K Mac. It let you program a robot to navigate itself through various environments. The programming language was innovative and was call "IBOL", as it was all icon based. I also have Musicworks - which let you write music and play it back, etc. And of course I have Macwrite and Macpaint in the original box. Both work on the Mac OS system version 1.0. I have an original IBM PC from the same era. I boot both of them up side by side and wonder why in the hell the PC won. (and yes, I know why, before you send your reasons) As much as I love my Macs, real programming died the day they invented the GUI. Give me an assembler and some silicon and a mission, and I'm a happy guy. > From: Phil Beesley <beesley(a)mandrake.demon.co.uk> > Subject: MicronEye > > Please don't tease, Craig.

I thought that that was due more to the fact (core) memory was asynchronous with a wide range of cycle times as well as I/O transfers. Only with memory being in the same box as the cpu does a more synchronous system make sense. >Classic CPU's were mostly NOT fully synchronous, as fully synchronous design >required the use of costlier faster logic families throughout a design when that >wasn't necessarily warranted.

What is so different a F/F is still a F/F, a gate is still a gate. It is only that routing delays are a unknown so you can't use logic that requires timing delays or or oneshots. It is only that the programs can't discover when logic can or cannot change like a designer can but must use worse case assumptions .It is only in the case when you have a single clock that timing calculations are the most accurate. How ever I suspect most CPU design starts with a clean sheet of paper lays out goals and basic design parameters. A good block diagram often can tell you how complex your system is. While gates are important the quantify and packaging of the gates define just how your system can be laid out. Only after the instruction set is defined do you look at the logic need to produce the Computer System, and once you lay things out you have good idea of what instructions are needed. Of course everything gets revised again and again. http://www.ulib.org/webRoot/Books/Saving_Bell_Books for some interesting reading. Also "CMOS circuit design,layout and simulation" ISBN 0-7803-3416-7 is very good reading for CPU design at the real gate level.

The American Heritage Dictionary of the English Language lists "One-off" as: Adjective: (Chiefly British) Happening, done, or made only once. Noun: Something that is not repeated or reproduced. Does anyone have an Oxford English Dictionary handy? It should give the date of the earliest in-print reference.

IT used to be Eispack (yes, the scope was much narrower for this one). Then Linpack. Now IT is Lapack, at least for dense systems; for sparse numerical linear algebra, there is a plethora of packages. Matlab challenge question: what does the dongarra(n) function compute?

Dec & Sun stuff available in Houston TX

by dlw＠trailingedge.com

I have just spent the last few weeks living a computer collector's nightmare.... moving. The entire collection had to be packed up, loaded, moved and unloaded. The good part is I now have a larger place and I'm taking the time to organize and get a better, newer inventory. During which I've decided to pass along some things I have extras of or will never get around to working with. There is more to come but I'll start off with some of the larger items. Item 1 - DEC PDP-8 stuff. Two card cages with various boards (not sure what all is in there at the moment), power distribution strip, and two RK05 drives. I think I have a PDP-8A front panel that went with all of it here too. All is in unknown condition. I thought I'd have time to try and do something with all this once but I know now I won't. Item 2 - Sun 3/50. System plus two 19" monitors, 2 keyboards and a mouse. Unknown condition. Item 3 - Box of various Sun OS tapes. If you have something you'd like to trade me I'll be happy to consider it but otherwise they're free for pick up in Houston TX. I often drive up to Austin (doing so this weekend in fact) and might be convinced to tote them along but can't promise. If nobody wants them then it's off to the local scrapper I guess. Other stuff available soon as I sort through all these systems and boxes. ----- "What is, is what?"

MCM Electronics. <http://www.mcmelectronics.com> although they are really a catalog company, not an online retailer, so I have found their web site lacking.

It comes in a small 2 oz or so bottle, kind of a yellowish liquid, and stinks pretty bad (I have a bottle at work, alas, I am not at work to give you better details). I think when I bought it I paid about $3 for the bottle, and it has lasted a LONG time. >I thought I had bought it before at Radio Shack, but they didn't have any or >a clue. RS staff being clueless?

Axil 311 Sparcstation 10 clone

by rmeenaks＠olf.com

Hi, I picked up an Axil 311 SS10 clone over the weekend to replace my IPX. I am not at all familiar with Axil's systems, so does anyone know what types of memory sticks I can use on this system. Also, can I replace the bootrom with 2.25R so that I can use Ross mbus modules? Thanks, Ram PS: I am assuming it is 100% compatible with the SS10, but a quick google search seems to give conflicting answers.... -- ,,,, /'^'\ ( o o ) -oOOO--(_)--OOOo------------------------------------- | Ram Meenakshisundaram | | Senior Software Engineer | | OpenLink Financial Inc | | .oooO Phone: (516) 227-6600 x267 | | ( ) Oooo.

All of this seems to belong to the "NORMAL" column. If the LINK LED stays off, I'd be inclned to believe the interface isn't working; on all the devices I've seen it, the LINK LED is on if the network is live. Seems odd if the DATA LED blinks when there's traffic, though. I wonder what that LINK LED really is for? > 3.

(OK, skip that until they work with their current addresses) Er, no, 111.0.0.0 is a real Internet address. Perhaps you're thinking of the "private" Class A network address, 10.0.0.0?

Also the name in the "arp -s" must match the name in /etc/hosts.

Assuming 0:c0:e2:0:c:8e is the printer's MAC address, and it does know its address is 111.1.0.1, that should work -- unless the printer interface is broken or it doesn't respond to port 2002. You could try ports 9099, 9100 (used by HP JetDirect printers), 515 (lpd port), 161 (SNMP), 7 (echo). Some of those normally use UDP rather than TCP, so you might need to get something like netcat instead of telnet, though. > Oh, and "permanent": After a reboot, the old (incomplete) is there again > instead of the MAC address. Very permanent indeed... It means it doesn't age out of the arp table the way normal entries do. Normal entries age out in case IP addresses change, or in case routers are doing proxy ARP for hosts on a different subnet (in which case if the route changes, so does the ARP entry). All entries still get lost on reboot; they're stored in kernel memory but nowhere else. -- Pete Peter Turnbull Network Manager University of York

Sun / CalComp Printer networking problems (was: Thick Ethernet/Sun networking problems)

by Arno_1983＠gmx.de

Oh Gosh, that's a lot of stuff... I think I should've mentioned I'm in digest mode... 1. Douglas Quebbeman and Dan Wright wrote about scanning all possible IP adresses. Besides taking an awful lot of time, this is no longer necessary because we got a status page printed out which states the IP address to be still 111.1.0.1. 2. Lawrence LeMay wrote: >So, it would help me if you briefly restated the exact problem. I'm assuming you have a calcomp plotter >(but i dont know which one), that it has a M971 ethernet card... That is, mostly, correct. What we're having here is a CalComp CCL600ES, a large laserprinter, hooked up to a Thick Ethernet segment together with two SUN SPARCstations (1+ and 2) (and a 486 PC for sniffing purposes). >...and that you dont know what the IP address is set to. (...) Well, one way of solving this problem is to >reset the M971 card back to factory defaults, and then setting the IP address.

There is a >reset jumper on the ethernet card, so you power down the printer, remove the card, install the jumper, >power it up, then repeat to remove the jumper (assuming i recall the procedure correctly). We're positive that the IP address is still the one it was set to all the time (111.1.0.1) because we finally got the Ethernet Adapter Status Page printed out. This is done by setting the JP1 jumper on the 971, reinserting the card into the printer, and then powering up. (I suppose this means we don't have to do all that 'automated pinging' stuff...). >http://www.calgraphinc.com/Support/unix_networking.html I'd already found and read this page. Amazingly, they mention only two of the three LEDs my Ethernet Adapter has (IP, DATA and LINK). During the warmup phase, IP (green) and DATA (amber) are illuminated. After that, the IP LED goes on with a blink (rather 2 than 5 Hz, I'd say...), while the DATA LED flickers whenever something is transmitted on the Ethernet. The LINK LED stays off all the time.

I agree to that. We now know the IP adress is still correctly stored. We also know the Ethernet interface is receiving every packet transmitted (flickering DATA LED). And we know that it doesn't respond - from the (incomplete); so the interface might really be kaputt - I don't hope so, however... >Ethan Dicks wrote: >>(...) >> I think it's useful when you have an ancient network where the broadcast address uses 0-bits, rather >>than 1-bits - i.e., ip 192.168.1.1 with a netmask of 192.168.1.0 and a broadcast address of >>192.168.1.0 *not* 192.168.1.255.

Friden Flexowriter (fwd)

by doug＠nut.net

Flexowriter available in Chicago (contact MHardig(a)aol.com). ---------- Forwarded message ---------- Date: Sun, 4 Nov 2001 19:12:32 EST From: MHardig(a)aol.com To: doug(a)blinkenlights.com Subject: Friden Flexowriter I have used these. As recently as a few years ago. I own one. It works, to the best of my knowledge, the punch feature anyway. I haven't figured out how to make the read feature work, but then this one is a lot newer than the one I trained on. The model I have is a late 60's, and spent most of it's life punching tape for CNC machines. Do you think anyone would be interested in this? I've had people interested but they're too far away to ship this ungainly bastard. I live near Chicago. Thanks in advance. Cool website! Mark Hardig

connectors needed

by jhellige＠earthlink.net

I'm in need of the following pieces and would like some input on where to pick them up: - 8bit ISA slot connector, female, 31pins - 31pin ribbon cable, approx. 3-4 inches long - dual row header, female connector, 31pins each row, spacing the same as the ISA connector. What I want to do is make a short adapter to go from the Tandy 1000 PLUS-style bus connector to an 8bit ISA bus connector. I have a small circuit board already that does the conversion the other way, allowing PLUS style boards to be used in an ISA slot but I wish to plug an 8bit ISA board into the PLUS slot. The adapter board is single layer and it shows it to be a straight conversion from the ISA bus to the first row of pins. I'm told that at one time DCS Industries provided such an adapter cable with some of their upgrades but I've not been able to get any answers from them as far as if they still have any. Thanks Jeff -- Home of the TRS-80 Model 2000 FAQ File http://www.cchaven.com http://www.geocities.com/siliconvalley/lakes/6757

In any hobby, a price guide is both a blessing and a curse. When I owned a sports card shop I became aware of the potential effects of price fixing and other forms of market manipulation. Specifically, if the publisher of a price guide had a bunch of Don Drysdale and Sandy Koufax cards to dump, those players would book high until he dumped his cards. Additionally, advertiser pressure influenced prices listed in these books. For vintage computers, a price guide published 2-4 times yearly, listing maybe 500 computers, might work. It could be advantageous to only include photos for 50 of these computers in each issue, rotating through all 500. This would encourage people to buy the next issue, with photos of 50 *different* machines. We have Ebay now, and other auction sites, from which to draw data. The publication might also consider any documentable, verifiable report from private buyers and sellers when compiling the price guide. And since when can your average scrapper read, anyway? Just my two cents . . . Glen 0/0

Need a source and info on a memory chip

by rhblakeman＠kih.net

This is off topic but I know that someone in this list will have the answer. What I need is a surface mount memory chip for a PDA 16mb upgrade of internal memory. The chip in it is an 8 and I've seen a unit with a piggybacked chip on it with a jumper run from the Motorola Dragonball cpu (I basically drew out the mod on a Wendy's napkin it's that simple). Here's what's on the face of the present 8mb chip (the piggy back will be the same or suitable sub): ---------------------------- HYUNDAI GM71VS65163CLT5 0040 AG2 KOREA ---------------------------- It's a surface mount chip that is a 50 pin DIP package (2 rows of 25 pins). I'll need one initially and end up needing around 25 so I might as well get all 25 at one time. Does anyone know where I can get a specs and/or pinout of this and a good source for purchase of small or large quantity? I want the pinouts/specs for curiousity and the source obviously for purchase rreasons. Any help is greatly appreciated.
