Hi, gang, Cleaning up today, thanks to lousy weather, and I've come across a couple of items I don't need. First is a DEC VT220 Programmer Pocket Guide. This one'll be a freebie to whoever wants it IF you're in the United States (I can send it for less than a dollar via postal). If you're outside the US, I'd ask for the cost of postage to be covered. Next up is a terminal emulation package made by Microplot. More specifically, it's called PC-PLOT-IV PLUS, and it is designed to, on a DOS PC, emulate the Tektronix 4010, 4014, and 4105 graphics terminals. It will also emulate a VT100. The 5.25" floppy disk says it's version 4.20J. For that one, I'll let you tell me what it's worth by E-mailing an offer if you're interested. Thanks much, there may be more to come as I uncover other hidey-holes. -=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com kyrrin (at) bluefeathertech do/t c=o=m "If Salvador Dali had owned a computer, would it have been equipped with surreal ports?"

Near-classic: Win95 beta CDs

by rcini＠optonline.net

Hi: I'm trying to track down a particular program from the Windows 95 beta program. I must have purged a bunch a while back by mistake. Here's what I'm looking for...I can't remember if it's on the Win95 or DirectX beta disks, but it's some sort of space station demo that enables you to access the various demo programs on the disk. Specifically, I'm looking for the WAV and/or MIDI files from it. If any remembers this and can put their hands on it, please let me know off-list. Thanks.

It would require some external decoder logic to get the ROM data to an external ROM. Also, the internal selects my be masked different than the permanent selects of the 6532. This would also require a little translation. There are no original 6530's with the KIM mask available unless one trashes a KIM to get it ( don't even think of doing that ). The SYM-1's don't use a 6530 so that is not an issue for them :) Dwight

I have 2 Poly88's and one 8813. This is an indication that the system is not running. The video memory quite commonly has failures but this usually shows up as a chunk of the video not responding correctly. The video uses 2111 chips ( often 9111 populated ). I am seeing some quadrant like behavior so it might just be a lot of bad video RAM. If anyone gets this that is on the list, I can help them bring it back to life. Finding some of the RAM chips that work may be an issue. I went through a pile of these that Achor Electronics had and found only one in three that was any good. The fact that the disk seeks is a good indication though. If it is in fact doing this, the ROM's must be doing something. Dwight

First some definitions: Appletalk is the protocol that Apple used for connecting to printers and other computers. Localtalk is the hardware specification. Looking around for the latter will give you a lot more information. The problem Apple (and others) solved is how to connect multiple RS232 (RS422) devices together without blowing everything to bits. Their solution was to use a transformer with two independent windings on the primary and one on the secondary (along with a few resistors). The secondary windings are paralleled among the various devices. The primaries are connected to the Tx and Rx of the RS232. This makes for a simple two-wire network. Normally, the ends of the secondary bus are terminated in 110 Ohm resistors. Apple's implementation used proprietary cables. Third party boxes (Farallon, etc.) used RS11 phone cables. I've seen these boxes at various charity outlets in the recent past going for next to nothing. If you have an old phone modem laying around (parts - not collectable...) you can use the output coupling transformer to make an adaptor. They generally have the two-primary/one-secondary format and have the correct ratio. The receiver side of the primary should be terminated with a couple hundred Ohm resistor. As a side note, there are a lot of Localtalk printers and the like showing up for cheap. Connection to Windoze and Linux boxes are generally a problem. There are cards that talk Appletalk, but they are fairly scarce. However, there are a number of bridges coming available that connect ethernet to Localtalk and the Appletalk drivers are available for both OSs. CRC

Polymorhic 8810

by Watzman＠neo.rr.com

I'd say that it's not working. The random display does suggest that a lot of the video card is functional. However, it also suggests that the ROM monitor on the CPU card isn't being run, which would clear the screen. This could suggest bad memory or CPU or both, but in any case I'd say that, contrary to what the seller says, the system is not functioning properly.

I've never had a real Farallon PhoneTalk unit so I don't know, but I suspect it has some real electronics inside, or a hybrid transformer like LocalTalk boxes. However, if you're starting from scratch, you might look at the CapNet subsitute.

VAX 4000-300 - Null Modem Cable

by phirkel＠sympatico.ca

Howdy! I recently acquired a DEC MicroVAX 4000-300 and I want to connect it up to an old PC that I can use as a dumb terminal. Unfortunately, I lack a proper null modem cable, but I have a nice length of phone cable (it's the same connector pretty much, if you sand down the clip, right?) and a nice length of serial cable with connectors on each end. My question is, is it possible to jury rig these two pieces of cable, so that I can have my VAX up and running for at least a single user (Ethernet will come later! ;) ). If so, what lines should I cross (pin numbers would be nice :). Thanks. Phil.

My plan was to read a track at a time in MFM mode to get both the clock and data bits which I could decode in software. The first problem was the index holes. I disconnected the index signal from the drive and routed the 1797's index input to a bit on an i/o port. (I was doing this on an H100 so I used the manual precomp line.) With index under software control I could create a fake hole, read as many bytes of data as I wanted, and the create another fake hole to terminate the command. The next problem was clock/data synchronization. Even in MFM mode the 1797 exposes only 8 bits (that is, every other bit) of its 16-bit data shift register to the cpu. Normally a special pattern with missing clock pulses synchronizes the register to the bit stream, but of course there is no such special pattern when reading FM data as MFM. I had initially hoped that there would be enough random variation such that a few attempts at reading any given track would result in at least one instance where the data was in the desired position. Unfortunately, the reading process turned out to be pretty much deterministic and if a particular run of bits was out of phase once it was likely to remain so. To solve the bit synchronization problem I intercepted the raw data input to the 1797 and delayed each pulse by 2 microseconds with half of a 74123, using the other half to produce a pulse of similar length to the original (not that the latter is critical). I then diode-or'ed the delayed bit stream with the original and fed the result to the 1797's raw data input. This guarantees that regardless of the clock/data bit phase relationship to the data shift register, all the bits are available to the CPU. Because the 1797 uses an external clock recovery circuit the timing of my delayed pulses does not interfere with accurate clock tracking. With the raw bits in memory I apply a simple algorithm to separate clock and data. I examine a bit. If it is a 0 it must be data and I shift it to the output buffer. If it is 1 I drop it and shift the next bit to the output buffer whether it is a 0 or a 1. With the data bits in memory I simply mimic the H17's normal operation by searching from sync bytes and accumulating bytes thereafter. Note that the bits in a byte for the H17 are reversed from most other disk formats. Dan Lanciani ddl(a)danlan.*com

Identify an SMD component

by chd_1＠nktelco.net

I have two identical 72pin memory SIMMS out of an HP workstation. One is damaged by having a single 3pin SMD component physically destroyed, with only the leads remaining. The second is complete and functional. The damaged component's reference designation is CR5, so I am thinking it is a rectifier and not a transistor. The black plastic SOT-23 package is marked with 5A followed by a K rotated 90deg counter-clockwise. Any suggestions on how to identify the part? Is there a pointer somewhere to how SMD components are marked? -chuck

Hi Sellam Of course, I'd love to have the 5110 but I have no idea how much to offer for such a machine.

MicroVAX3100 boot disk limited to 1GB - which ones?

by trash3＠splab.cas.neu.edu

I have a 3100-40 which has a 4Gb drive as a boot drive. The model 40 is SUPPOSED to be the same as the 30, but different case, expansion, etc. The model 30 memory certainly works in the 40. I seem to recall it is more an issue of age of firmware. I just asked a computer parts place I do business with about my model 30 and they said a 4Gb drive is the biggest that will work in it. Didn't try it though, just went to the model 40 (needed the space for more drives). Joe Heck

Rust on tape heads

by dwight.elvey＠amd.com

Hi If the heads themselves have some rust, you need to polish the heads a little before dragging tapes across it. The rust pits will have sharp edges on them that will damage the tapes. You should use a fine polishing compound, like jewelers rouge or cerium oxide to burnish the edges so they don't do more damage.

archiving Heath H8/H89 hard-sectored disks

by dwight.elvey＠amd.com

Hi Dan We have a separate mail group specifically for H8/H89 and also a program archive. We are interested in disk images as well. I have written a bootstrap method of bringing a H8/H89 machine up from scratch with a serial cable and some blank disk. This can also be used as a general disk image transfer program. We would like to get any information on your methods into the archive and also images you may have. Send a message to <majordomo(a)staunch89er.com> with body: subscribe sebhc To get to the mail group. It is a quite group right now but the archives have a lot of good stuff.

I've written a program that handshakes with the Poly 8813's ftp program ( not to be confused with todays ftp ). It can be used to transfer programs/files to and from the Poly 8813. I don't currently have a way to copy entire disk images but if you have a bootable disk with the ftp, you can transfer files ( using my program that requires a PC with DOS ). I have schematics for the CPU and video boards but nothing for the RAM or disk controller cards. Do you have an 5-1/4 drive machine or do you have 8 inch drives? Email me directly and we can talk more. Dwight

Rust on tape heads

by GOOI＠oce.nl

I would first check if the rust is actually from the metal of the head or just "rust" that has come off from an old tape ... that can probably be removed with a soft cloth. I am not so sure about using *any* fluid on the head! I do not have experience in this field, but don't those heads have a small slit / gap?

OT: Submissions for an IT careers book?

by evan947＠yahoo.com

Hi all... I'm putting together a guidebook about IT careers for Vault.com (a jobs and careers site here in New York). I'm writing the majority of the book >from personal experience, but my editors asked me to solicit a few "day in the life" sidebars from people in the field. The idea is that someone such as a student can read the sidebars to get an idea of what you actually DO all day in the role of (fill in your title). I could use some submissions for jobs such as network engineers, SAN/backup administrator, QA engineer, tech writer, product manager, etc. (already have one from the programmer specialty). Basically you'd just write a fictional but realistic hour-by-hour scenario of what your typical day is like. It's up to you whether your name/company name are included. Of course, the benefit to having your name/company name included is the free press and the glory of pointing out your name in print, the next time you're in Barnes & Noble with friends. :) The catch? I need some of these sidebars as soon as humanly possible, in the next couple of days. Thanks in advance to anyone who can help! - Evan (PS -- please reply directly to me, let's NOT make this a discussion thread.)

DEC VT stuff & HP stuff

by jwest＠classiccmp.org

The VT100 power supply has been spoken for (as have the keyboards). The LA120 has tentatively been spoken for. The next round of offerings will probably be a rather large amount of HP 21XX interface cards. They will be posted here soon as I go through and run diags on each one (so they will all be known good boards). This will take some time as there's about 150 boards I have to go through :\ I'm looking for 12880 cards, 12920/21 mux sets, FAB boards, FEM boards, and 12531 HS terminal cards. Also DG eclipse cards. Still looking for a DG 6031 floppy drive, and HP 264X terminals. Regards, Jay West --- [This E-mail scanned for viruses by Declude Virus]

Newbridge VIVID ATM Network Kit Available

by kevan＠heydon.org

I have some ATM kit that needs to find a new home. It ideally needs to be picked up from Cambridge UK but I can be flexible. Not sure if this kit has reached the ten year limit yet, but the fact that it's ATM fibre and is full of blinking lights surely makes it interesting to this audience. A couple of quick pictures first: http://www.heydon.org/kevan/pictures/newbridge-small.jpg Same but bigger: http://www.heydon.org/kevan/pictures/newbridge.jpg What you are getting is a complete setup consisting of the central Route Server (really a Sun SS20), a 12 port ATM Workgroup Switch and two 12 port 10/100Mbit ethernet Orange Ridges. All these are connected together with fibre. I have the rack mounting brackets too. It's all working fine and sat purring away, next to me at the moment. Building work starts at home in a few weeks time and it has to be gone by then. -- Kevan

TV Show Alert for Aug 30th, 2004 in US

by gmanuel＠gmconsulting.net

Today at 11:00am Eastern on the Discovery Science Channel (just Science Channel now) is a show called BrainChild (listed in my cable listing as Computer Revolution). It is a 2003 documentary about the invention of the computer and covers the evolution to the integrated circuit. It also covers some info about fiber optic cable creation. It was also on at 3:00am today. Kinda neat seeing the Eniac and hearing the programmers and designers talking about it. Sorry about the short response time but I found it channel surfing.

National Multiplex data cassette tape drive

by wmaddox＠pacbell.net

Years ago, I owned a data cassette drive made by a company called National Multiplex, presumably long defunct. It was obviously a modified audio cassette recorder, but in which the internal electronics had been completely replaced. Unlike the prevailing standard for cassette-based data storage on micros in that day, this drive used saturation recording (NRZI, I believe) instead of a modulated audio carrier. It was a very functional replacement for a paper tape reader/punch, and ran up to 9600 bps using hi-fi grade audio tapes. I would be interested in locating one of these beasts to replicate the setup I had on my IMSAI before I sold the drive years ago. The drive came with schematics, and as far as I remember, the circuitry was rather simple -- a couple of op amps and a few gates. Alternately, if I can locate a copy of the drawings, I may attempt to reproduce the design using a contemporary audio cassette mechanism. Has anyone ever seen one of these? --Bill

Help with question about web page access

by jhfinexgs2＠compsys.to

I realize that the 2 questions I have are NOT within the 10 year rule, but I really could use some help! While I have been using computers for over 40 years, I have stayed with very old systems as far as programming and writing programs is concerned. Thus, under Windows 98 SE and Netsacpe 4.78 (which is what I am using to access the internet and this news group), I am ONLY able to use the operating system and the application; I am NOT able to make any modifications which is how I usually proceed when I encounter any problems. Last week, the web site that I usually access in a very standard manner using Windows 98 SE / Netscape 4.78 no longer provides the information I used to obtain. The reason is that the company which controls access to the web site decided to add additional features which require the use of at least Netscape 7.0 by the user. And while I agree that the company has every legal right to do so, at the very least some sort of warning could have been provided which was much more apparent other than placing the information under a link titled "required browsers" that I understand did provide some advance notice. However, at the SAME time, the error page which informed users that cookies were REQUIRED listed (and still lists) Netscape 4.x and Netscape 6.x as the required browsers if cookies were turned OFF. Some more background information: Because I ALWAYS run Netscape with cookies turned OFF, except when I am required to have cookies enabled to access the 2 web pages that I normally use, I often encountered the error page which listed Netscape 4.x as one of the required browsers. Since EVERYTHING works when cookies were enabled, I never bothered to access the "required browsers" link as the error page certainly seemed to provide that information when I forgot to turn cookies ON - which usually happened at least once a week. ALSO, while I am not able to fully use the web site, I am able to "log in" (with a userid and password) to get to the first level of information that I request. It is only subsequent screens that I am unable to FULLY access, i.e. when I request the next level of information, the next screen is reached, but the changing information is no longer displayed under Netscape 4.78, ONLY the top portion with the headers, etc. I have 2 questions: Based on the information on the error page, would a normal user be ALSO expected to look at the "required browsers" link when the specific naming of Netscape 4.x was (and still was when this post was made) displayed as an acceptable browser when I forgot to turn cookies ON? Could the company have continued to allow users access to the web site under Netscape 4.78 by the expedient of NOT providing those users the additional features that users of Netscape 7.0 and later are provided? NAMELY, do the fellows setting up the program have the ability to check as to which version of Netscape is being used and could the program have retained the old code for those users who stayed with Netscape 4.78 and used to new code for those users who shifted to Netscape 7.0 and later? I realize this post is very long, but I hope it should be possible to answer both questions with a simple YES or NO! If you wish to add an explanation, that would also be VERY MUCH appreciated! Sincerely yours, Jerome Fine -- If you attempted to send a reply and the original e-mail address has been discontinued due a high volume of junk e-mail, then the semi-permanent e-mail address can be obtained by replacing the four characters preceding the 'at' with the four digits of the current year.

WTD: help debugging an eprom emulator

by philpem＠dsl.pipex.com

Hi, Sorry for clogging up classiccmp with this message, but it is sort-of classiccmp related (I wanted to build an EPROM emulator to make ROM development on my BBC Micro a little faster). I've been trying to get my EPROM emulator design to work - I can't see any errors in the wiring and AFAICT all the ICs are fine. I've uploaded the schematic to <http://www.philpem.me.uk/epemsch.png>. If anyone spots a design error, please let me know - I've gone over the schematic a few dozen times and I'm almost at the point of giving up :-/ It looks like data is getting loaded, but isn't getting output to the target device properly... %DEITY knows why, though... Thanks. -- Phil. | Acorn Risc PC600 Mk3, SA202, 64MB, 6GB, philpem(a)dsl.pipex.com | ViewFinder, 10BaseT Ethernet, 2-slice, http://www.philpem.dsl.pipex.com/ | 48xCD, ARCINv6c IDE, SCSI ...

HP 2100 book sought ($BOUNTY$)

by jwest＠classiccmp.org

I'm looking for an original copy (not pdf or other electronic format) of the "HP Pocket Reference Guide to the 2100 Computer". Unlike the title suggests, it's hardly pocket-sized. It's about 450 pages, with roughly 5x8 pages. I'm willing to pay non-trivial sums of cash, or provide lopsided trades, for said book.

CPU Chips

by bmachacek＠pcisys.net

I have been salvaging old computers now for over 6 years and have kept all the CPU chips that I have found in them. Most of the chips being from 386, 486, and Pentium I computers. Is there a list anywhere that identifies which of these chips might be rare or hard to find? Before I scrap them for the gold content, I'd like to find out if any of them might be worth keeping or selling to someone interested in a particular chip. Thanks for any information you can give me.

dec LA/VT stuff available

by jwest＠classiccmp.org

I have a Decwriter III (LA120) available. Never plugged it in, somewhat yellowed case, missing the break key. Very dusty but otherwise in good condition. It's taking up way too much space so I want it gone quick - otherwise it gets pitched or stripped for spare parts. Also have available 2 or 3 VT100 keyboards. Fairly yellowed, one is missing one keycap, the other is missing about 5 keycaps. Good for parts - they get pitched if no one claims them. Jay

HP memory available (HP9000)

by jwest＠classiccmp.org

Maybe not quite vintage... but I have these, and no need for them, and would rather trade or give them away than toss them. I have four memory modules labled as follows: Series 800/900 Memory 32mb A2511-69001 The extractor handle on each module (and the label) says 32mb. But being somewhat familiar (although rusty) with HP part numbers and modules of this type, it is possible that even though it says 32mb on each module that each one is really 16mb, as modules were always sold in pairs for these particular systems. Knowing the origin of this memory, it mostly likey came from a G machine, or possibly a K machine. I cant be sure, but I suspect they are working fine. If anyone wants them let me know quickly...

Best keyboards you've used ever!

by msokolov＠ivan.Harhan.ORG

Mark Wickens <m.wickens(a)rhodium-consulting.com> wrote: > List the best keyboards you have ever used. Right now the keyboard I insist on using is LK201, but that's only because I'm a nut about DEC VTxxx terminals and don't want to use a keyboard whose set of function keys does not directly correspond to the set of VTxxx transmitted escape sequences. I like LK201 better than LK401 because I have no use for the latter's "Alt function" keys, because I don't like how they shrunk from 4 to 2 LEDs, and because LK201 is more sturdy while LK401 is more flimsy. The really interesting keyboard I've used (for Western readers) is the Soviet KOI keyboard. Unfortunately I never got to use the "real deal" (Soviet serial terminals), but I've used the KOI kbd on the BK0010, the Soviet home computer based on the 1801VM1 microprocessor, a Soviet PDP-11 clone, a single chip microprocessor roughly equivalent to an LSI-11. It was a home computer for which you were expected to write all software yourself from the ground up, by entering octal codes at octal addresses (assuming you wanted something other than BASIC or FOCAL that they had in ROM). I really miss that mentality (I still believe every hacker needs to write his own operating system as a rite of passage). Soviet KOI keyboards are really interesting. They are based on KOI, which is the Soviet reinterpretation of ASCII. In Latin mode KOI is identical to ASCII, but thought of differently, in that all characters from 100 octal up are considered Latin letters, so in the mind of a Soviet hacker, '@' is the 0th letter of the Latin alphabet, '[' is the next Latin letter after Z, and the last Latin letter is '_'. In Russian mode characters from 100 octal up are given alternative graphic renditions (Russian letters, not surprisingly). Note that it's the *graphic rendition* of the character that changes, not the character itself; the coded form is the primal form: a compiler will recognise a keyword equally well regardless of whether the tty displays it with the Latin rendition or the Russian rendition. The KOI keyboard was designed around this mentality, i.e., the upper/lower case switch acted on all keys that we considered letters. '{' is the lowercase '['. The layout was different. When we got the first PeeCees I at first couldn't stand their kbd because of the top row layout: how ridiculous it is that '^' (a letter) is on top of '6' (a digit). That drove me nuts. The KOI keyboards were much more rational in that the key layout directly corresponded to the ASCII/KOI chart. The top row keys were in their ASCII/KOI order. The encoding logic was a breeze since with this layout all modifier keys (Ctrl, Shift, upper/lower case switch and the RUS/LAT switch) only had to twiddle bits. MS

6809 Forth (was: Sharp PC124x/5x/6x)

by dave04a＠dunfield.com

>You would get the 2 versions that I already have :-). I'd like to see the >6809 fig forth (I assume it existed, and used the 2 hardware stack >pointers, etc). It's not fig, but if you are interested, you can take a look a my tiny little FORTH implementation for the 6809 - Docs are a bit sparse, sorry - it was done on a weekend in response to a collegue who had been boasting that he had created a version of FORTH for the 09 that was faster than any other - I truly enjoyed the look on his face the next monday morning when his test program ran significantly faster on mine... Of course I cheated - my FORTH compiled to directly executable code, which eliminated the interpreter and chaining through threaded links - this has a bit of overhead (3 byte JSR instruction instead of 2-byte link address), however it is offset by the fact that I reduced the header to just the word name (no difference between word types - everything is "native"), which saved me 16 bytes (IIRC) over the wordsize in his dictionary. Yes, it uses both hardware stacks. If you are interested in playing with it, it's available on my museum web site, in the section on my D6809 homebuilt. The source code is included, and if you want to try it out, you can run the D6809 emulator, mount the included disk IMAGE, boot up my CUBIX OS and type FORTH - this will launch a ready to run version of my itty bitty FORTH (about a 2.5k executable as I recall).

HP LA Inverse Assemblers for classic microprocessors

by RupertKirkham＠compuserve.com

Dear Jim, I followed this thread and tried the "FTP" addresses that were given regarding downloading the Inverse Assembler Development Package. Sadly without success as the directory structure has been changed. Therefore is there any chance of obtaining the software from another source. Funnily enough I have the reference manual as this is downloads from a couple of web sites. I am currently building a 68008 based system and I would like to have an inverse assembler for the HP1650A that I will be hooking up to it. Regards, Rupert.

floptical drives

by julesrichardsonuk＠yahoo.co.uk

Hmm, my first ever floptical drive just landed on the doorstep amongst a pile of hardware. Never seen one before now, and it seems there's very little info on the web about the technology. I assume that although it'll (probably) read/write normal 3.5" floppy disks, it needs special media to reach the 21MB that I keep on seeing quoted in various places? (i.e. it can't reach that figure combining the optical tracking technology that it uses with standard magnetic media) (the drive's an Insite I 325VM, likely culled from an SGI I think) cheers Jules

Toshiba 3200 questions (wireless?)

Finally really digging into my toshiba 3200 and have a few questions maybe others know: 1) Even after adjusting the contrast & brightness knobs on the side, I can't get a black background. The background is decidedly orange-ish still. It's been over 20 years since I used a plasma screen. Is this normal, or is my screen possibly challenged? 2) I want this thing to work on my home wireless network. I'm assuming there are no ISA wireless cards, especially with DOS drivers. So I was thinking Xircom pocket ethernet adapter and a wireless bridge. Anyone have any better ideas? Thanks for any advice! Jay West

Not only that, the #1 driver they used is also buggered up because they have been incorrectly using it as well. Most Philps screws are actually #2 and not #1. Make sure you have a #2 in your tool box. If you have a good screw driver and you place it in a screw, and the driver feels loose, it means you are using the wrong size driver! Don't judge this by the amount of blade that isn't in the screw. The screw driver will be snug in the screw when right. Much of the blade may not be in the screw. Dwight

$2 Sale, or $1 if it needs to be.

by aw288＠osfn.org

OK, time to clear out more junk. Each of the following is $2.00/each, plus shipping from 10512: 1) Colecovision steering wheel Expansion Module, with extra joystick. 2) Some sort of 68000 based Western Electric AT&T modem board for a PeeCee - it actually looks like pretty much a standalone 68K based thing, with some WE chips and three connections to the outside world. 56K CSU? 3) PeeCee card with four serial ports and three bidirectional parallel ports, with cables. Unknown maker. For the I/O junkie. 4) AT&T KDB301 keyboard, I think for that Unix PC thing. It has a DE9 connector. 5) Miniscribe model 8425 hard disk on a PeeCee card (Hardcard lookalike). 6) AT&T American Bell (a Baby Bell I never heard of) model EASI-1B synchronous to asynchronous RS-232 convertor. A true black box of magic. 7) Pre-Borland copy of Brief v1.33 editor, with original disk. 8) Intel PLDshell PLD design software, still sealed. I think this only does Intel chips, so don't get too excited. 9) Book, using the Horizon Spreadsheet with the Unix Operating System, by D. H. Beil. A fairly disgusting early 80s spreadsheet. Stuff is untested (including the book), but generally in decent shape. I take cash, checks, MOs, Paypal (but NOT to this email account! Please ask!), coins, favors, and begging. I might add a little on to shipping for my time ("handling"). First come, first served, but I can change the rules if I either like or dislike you. William Donzelli aw288(a)osfn.org

Everything else is great, but here they just screwed up. On VT320, though, there is a setup option to turn the '`~' key into ESC (putting ESC where it belongs to the left of 1), move '`~' down to where the screwy '<>' key is, and put '<>' where they belong on top of ',.'. Needless to say, that's the mode I use. Of course what I would really love would be a Classic keyboard with the original Classic ASCII layout, i.e., ESC immediately to the left of '1', Ctrl immediately to the left of 'A', separate CR and LF keys, separate BS and DEL keys, and all of the previous 4 plus BREAK being in the area where you find Enter and Backspace today. Having the top row keys in ASCII order would be nice too, as would having the kbd send ready ASCII down its wire instead of funky scan codes. MS

FS/FT: SAGE junk

by aw288＠osfn.org

I recently obtained a number of modules from a SAGE AN/FSQ-7 (or-8) computer, and seeing that I will never even come close to thinking about having the whole thing, I could probably part with one or two. These are the real deal - complete with the original IBM numbered tubes. I don't know what the modules do. I'll trade one (or more) for something interesting (I think most people know what I like), or maybe sell one or two for a good pile of cash. William Donzelli aw288(a)osfn.org

Burroughs Part Numbers

by aw288＠osfn.org

Can anyone out there tell me what Burroughs part numbers look like - specifically the house numbers they used for TTL and such? I have a bunch of chips with 1471-**** numbers that I strongly suspect are Burroughs ECD types, but I would like to confirm before I decide if they go to the refinery. Pickier question: Did the Burroughs mainframe people use the same house numbering scheme as the ECD people? William Donzelli aw288(a)osfn.org

Looking for DOS command-line e-mail client

by vcf＠siconic.com

Does anyone know of a free or cheap DOS (i.e. not requiring Win32) command-line e-mail client? I'd like something that I can use to send off short messages with just the command line from DOS with TCP/IP drivers already installed (via MSNC). I Googled but only found programs for Win32.

Burroughs Part Numbers

by unibus＠gmail.com

Where I worked in the early 80s had a reference printout that gave the conversion between Burroughs part numbers and the industry standard parts. Thought some of that series were Farchild microCTL chips used in systems like the B6700. Sorry, don't have access to the printout as it would have been dumped years ago. Regards, Garry

Nintendo also uses them on their Super NES / Famicom Deck housing and game cartridges (not sure about the original NES/Famicom). They managed to pretty much defeat their purpose by placing them in "wells" in the plastic so you can wedge a pair of correctly sized tweezers between the well wall and the screw head and apply enough traction to get them out.

dos electronics software?

by GOOI＠oce.nl

Great! Thanks, Ben. Had not found this one. "coco" is a good term to include in the search :-) Will continue looking, but if no cheaper source turns up, I think I will spend the $31 out of curiousity to see the actual performance it claims. The page says that the 63C09 runs cooler than the 6809. I can confirm that the 68B09 at 1 MHz is warm, but I heard from Vince that the 6809 at 1 MHz gets quite warm! tnx, - Henk. > -----Original Message----- > From: cctalk-bounces(a)classiccmp.org > [mailto:cctalk-bounces@classiccmp.org]On Behalf Of ben franchuk > Sent: donderdag 26 augustus 2004 8:01 > To: On-Topic and Off-Topic Posts > Subject: Re: dos electronics software? > > > Gooijen H wrote: > > Hmm, I tried to post this yesterday ... probably something > went wrong.. > > I am looking for a 63C09E or 63B09E.

dos electronics software?

by GOOI＠oce.nl

Hmm, I tried to post this yesterday ... probably something went wrong.. I am looking for a 63C09E or 63B09E. Anybody knows where I can buy it?? I found a source in Australia, but that is the 63B09. The suffix "E" is important, it is the *external* clock version, as used in the Core Board of the Blinkenlight project (40 pin DIL case). I have a PDP-8/e simulation running on th Core board, but could use a performance increase. Upgrading to the Motorola "B" parts will allow to double the clock frequency, but the Hitachi 63B09 is even faster, as it does many 6809 instructions in less cycles. Interested in the sim? Check my 'Homebrew PDP-11' page, the link there is "spin off" ... - Henk, www.pdp-11.nl > -----Original Message----- > From: cctalk-bounces(a)classiccmp.org > [mailto:cctalk-bounces@classiccmp.org]On Behalf Of ben franchuk > Sent: donderdag 26 augustus 2004 5:21 > To: On-Topic and Off-Topic Posts > Subject: Re: dos electronics software? > > > Ethan Dicks wrote: > > On Wed, Aug 25, 2004 at 03:17:34PM -0400, Roger Merchberger wrote: > > > >>Also, if you're looking for something "more updated" > there's always the > >>Hitachi 63C09 - it's 4 Mhz, and has more registers, a > 16-bit integer > >>multiply (with a 32-bit result) and clock for clock is > faster than the 6809. > > > > > > Is it pin-compatible with the 6809? > > > > -ethan > > > > Off hand I think it is pin compatable since it was a 6809 > replacement part. > The gota is the hardware designers upgraded the core > instruction set to > switch instruction sets from the 'Motorola 6809' to the > 'Enhanced 6809' mode > with a mode changing instuction.Since they had a license to sell only > 6809 parts > this information was never documented other than hardware > hackers on the > internet. > More information can be found here. > http://www.concentric.net/~Alxevans/index.html > >
