I found an odd looking board today that I THINK might be some kind of delay line memory. I'm trying to find out more about the ICs used on it but I'm not finding much. Can anyone id these ICs? MC1662L, MC1043P, MC1010P and MC1040P? They are all 14 pin DIPs expect for the 1662, it is a 16 pin DIP. All of them are dated 1973 to 1976. They are definitely not sync chips or PICS! The board itself has seven glass or plastic cylinders about 3 1/2" long and 1/4" in diameter. Each cylinder is wound with a twisted pair of fine wires. Besides the beginning and ending points there are six additional taps in the windings. (A total of 8 connections per wire per cylinder). There are four 1662s next to each cylinder and the white wire of the pair is coupled to them. The red pair of the pair connects to a post that goes through the board. On the back of the the board is a daughter board that is seated on the posts. It has the 1040s, 1043 and 1010s on it. This board also has a row of four ICs for each cylinder. There are two 1043s and an two 1040s in each row and they apppear to connect to the posts that connect back to the red leads on the cylinders. The four 1010s are mounted on the bottom of the board between the rows of ICs and seem to be pre-drivers or some such. There's also a row of pre-drivers or something like that on the main board. They use MC1668L s and there are seven of them. These boards came out of a LARGE test system built by Tektronix. (The same one that I pulled the DEC PDP-11/35 out of.) But someone else pulled these and I'm not sure what unit that came from. The main board and outside panel are marked "2941 Delay" and the daugherboard is marked "Delay Register". Any ideas what these boards are? Can anyone positively id the ICs? Joe

HP storage formats on ss80 protocol disks

by peterbrown10＠hotmail.com

Hi Joe, Bill, Tony, Sorry for the delay in replying - the 'proper' job takes precedence unfortunately! Joe - bit of a typo on my part the 9133 appears to be CS/80. Can you explain the differences between CS/80 and SS/80? I seem to remember that CS stands for Command Set and SS stands for Sub Set but other than my lack of knowledge is complete. I have an HP 1000 based system (the 5451c) that runs 7900 and 7906 drives - are these CS/80 based too? It would be useful if I could back the software up on these. I think that the HP ISA card just allowed you to put DOS partitions on HPIB disks not read partitions in other formats. How can I tell if the drive is from an HP 9000 200 or an HP 9000 300 series system? Do you still have your HP LIF foramt description document? - any chance of a copy? Bill - Thanks for clarifying the HP 88500A harware capabilities Tony - thanks for the pointers with the LIF format. I took your byte tables and overlaid them with the data blocks that I am pulling off the disk and they agree very well (all of the record position / record length values seem to be correct). I have a few questions. The volumme label / descriptor block, bytes 16-19, returns a directory length of 1 but when I directory the disk I get around 280 filenames. A directory of one block would only support 32 files - where am I going wrong? In the tracks per surface, Number of surfaces, Records per track fields I get all zeros - does this just mean that the drive does not report them? What is the LIF file structure for text files? Thanks for your replies Cheers Peter Brown _________________________________________________________________ Get Hotmail on your mobile phone http://www.msn.co.uk/mobile

Classic Computer Software stores?

by nampcjr＠yahoo.com

Well, one of the "stores" I found was an online one. Granted, its not the GREATEST place as far as quantity and selection, but they didnt have what I was looking for either.http://shop.store.yahoo.com/classicsoftware/clasadgam.html Another place I have been looking, and even posted a place on the "wait list" is called the "Ye Olde Infocom Shop". Its a trader who has a nice selection of items...for trade and for sale as well....and NOT all just Infocom stuff...http://www.if-legends.org/~yois/index.php Im looking for the boxed version of Agent USA, but if someone accidentally slipped an image to me, I would not cry either...but my goal is to have the original....There is a remake out there on the abandonware scene....but I hate to tell them...it is just that...a remake....no game of 1.6mb fit on one 5.25" DSDD floppy :) Brian The New Yahoo!

I can mic the shaft, I > can count teeth, but the rest eludes me. There are two common ways of specifying gears. One is by diametral pitch (DP), where you specify, in effect, the distance between teeth (actually it's done by dividing the number of teeth by the pitch diameter). The other, mostly used for metric gears, is by "module", and is the reciprocal of DP, ie you divide the pitch diameter by the number of teeth. Gears that mesh will have the same DP (and, of course the same module). The trick is to find the pitch diameter -- that's the "effective" diameter of the gear wheel. If you're using DP, for normal gears the amount of the tooth above and below the pitch diameter, called the addendum and dedendum, is standardised, and it conveniently works out such that if you can accurately measure the outside diameter (OD), and you can count the number of teeth (t), you can easily work out the DP without actually measuring the pitch diameter directly: OD = (t+2) / DP therefore DP = (t+2) / OD and if you do need to know the pitch diameter, then since DP = t/p it's just p = t/DP. There's just one caveat: those formulae only apply to gears with a 20 degree pressure angle, and with more than 15 or so teeth (otherwise you need to make some corrections as the angles get more extreme). -- Pete Peter Turnbull Network Manager University of York

tape stuck in a TK70

How does one get a tape out of a TK70 when it doesn't want to let it go? Tried powering on / off a few times, hitting the unload button 3 or 4 times in quick succession etc. Wish the TK50 / TK70 QBUS controller cards had some firmware diagnostics that one could access, like retension tape, unload tape, etc... greg

It's Alive! (HP 1000)

by rigdonj＠cfl.rr.com

Last night I cleaned up the HP 1000 that I picked up a couple of days ago and double-checked everything. Then I powered it up. It came up with no problems. Next I punched in some code into the front panel and run it. I spent three hours or more changing the program around, moving it to different memory locations, running it with different data, etc. Everything is working perfectly. The two broken switches haven't been a problem. I just poke my finger into the hole in the panel and press the contacts. Now I have to get busy and built a terminal cable and hook up hard drive. Joe

HH drives

by aeg＠paradise.net.nz

Hi All I have a newbie question <collective groan from list> I don't have much experience with HH type drives and recently unearthed a Wyse Technologies machine at the local refuse recycling centre (it's a shop rather than me wading though a landfill site - I'm not that desperate). Inside this machine (stated built in 1986) were two HH type 5.25" hard drives (one a Segate ST-251 the other not branded but built 1989). On boot up I get: Pheonix 80386 ROM BIOS version 3.53 (c) 1985, 1986 Pheonix Technologies Ltd 640K Base 1408K Extended Memory Hard Disk Failure I have booted the system using a floppy and one drive (the unbranded one) is partially readable. It is a 41Mb drive split into two partitions (primary & extended) - FAT16 system It seems to have been installed with DRDOS. Using my later versions of DOS on floppy I cannot get the drive to respond to any standard commands (I always get a 'Sector not found' error). Can anything be done to revive these disks or were they left unparked and now physically damaged? I have another 5.25" hard drive displaying the same unresponsive characteristics... are they all dead? Thanks in advance Alan

ASR33 reader

by charlesmorris＠direcway.com

OK now the light has finally come on. Thanks to all who provided different pieces of the puzzle. I had assumed that the PDP-8 turned on the reader, read in however many words from the tape reader it wanted, and then shut it off. It never occurred to me that DEC would toggle this line on every character read, let alone hard-wire this function, given the very slow speed of the tape compared to even a PDP-8! I suppose I could have figured this out by looking at the M706 schematic though... So I'll put a relay in my ASR33 but I'm don't think I'll wire the power switch connections, just the reader magnet path. I wouldn't be using the 8/L and TTY without both being turned on anyway, and only an SPST contact will be required. -Charles >From: Ethan Dicks <erd_6502(a)yahoo.com> >The KCC IOT (6032) clears the Reader Run flip-flop that drives >the buffer that activates the relay. >When the code running on the PDP-8 tells the console hardware to read a >byte from the console, the normal sequence of IOTs toggles the bit without >any extra programming required.

Where can one find 2.5 inch floppy disks, and other odd sizes

by kurtk7＠visi.com

I know this is a strange request for help, but I have done a lot of searching for sources of odd sized floppy disks, and haven't had much luck. The 8" disks are not so much a problem, but from what I can tell, there were 2.0, 2.5, 2.8, 3.0, 3.25, and 4.0 inch formats and finding even one example has become a challenge for me. Since 3" disks were popular with the Sinclair systems, these can be had off Ebay, but what of the rest? Its a personal quest to one one copy of every type of removable media and if anyone has any ideas, sources, information, it would be most appreciated. I hope to post the collection to a website as I don't think it has been done. Thanks for any input Kurt (Still seeking a copy of the manual for the Jupiter Ace 4000, but I am hopeful as there is one possible source if I am lucky)

Marked "W0 RSTS (3/86)" - presumably from March 1986? - "RSTS/E Device Requests" by Jeffrey L. Clark, "(11/79) W0-DEVICE". 19 pages. I'm hoping to get time to scan the last two documents, which are interesting to read, and possibly somewhat helpful to RSTS/E people.

This is the case with both the AV410 and AV4300 I have. My AV530s/5500 seem to be okay, but it's just a matter of time before they face the same problem. The machines with dead NVRAM will give some cryptic indication of the problem like printing "IDPROM" and nothing else, and refuse to initialize/boot on power-up. 'r. bear stricklin' was collecting NVRAM dumps for analysis, so we can try to load usable data into replacement parts, but I've no idea where that stands. I haven't bothered getting a part to see if, like Suns, the machine will function at all with an uninitialized NVRAM. Anyway if you search the archive for his name or Aviion I'm sure you'll find the relevant post. Or head to this URL: http://www.bears.org/~red/museum/aviion-nvram.html The 88k Aviions were frequently SMP capable, though unless you've got rackmount or square/big deskside units they're probably just 2-way. If you think the daughter card on yours is a second CPU complex, look for a chip marked 88100 or 88110; those are the CPUs. The 88200's or 88410 are cache/MMU chips. DG/UX will support SMP out of the box. It's a decent enough SVR4 implementation, with X11 (R?) and some sort of logical volume system.

by classiccmp＠trailing-edge.com

In the hope that others can mirror them, I've put up over 1000 DEC manuals from the late 80's and early 90's up on the web. They hardly seem "classic" to me, since when I started collecting computers these items were brand new, but they *do* meet the 10-year definition! http://www.trailing-edge.com/~shoppa/dec94mds/ Again, if you do set up a publicly-accessible mirror for these I would appreciate it. The last thing I want to do is hoard stuff I've been sitting on for many years. Tim.

Amiga 2000 "Video Toaster Powered"

by doc＠mdrconsult.com

Hi. I ran across an Amiga 2000 yesterday, with the front of the case silk-screened "Video Toaster Powered". No cables, keyboard, docs, or anything else, but the price was right. The motherboard is probably junk. The battery has leaked and etched a pretty large area, plus the GVP 030 accelerator (A3001) has dumped rubber sludge on the board. The rubber button on the back of the board *melted* and ran like hot fudge. http://amiga.resource.cx/gallery/A3001-50-back.jpg shows the button intact. Beware; that's a half-meg pic. There is a RAM-32 daughterboard, too, with 2x 4MB SIMMs, http://amiga.resource.cx/gallery/A3001-RAM32.jpg and a GVP SCSI hardcard with a 340MB drive and no DRAMs installed. The Video Toaster boardset is labeled v1.0, but there's a sticker that reads "Eval Board 08/90" It's cabled to a Faruodja Labs board, a "Y/C Separator Board". http://amiga.resource.cx/photos/photo.pl?id=ycp100 Also installed are 2 ISA cards by RGB Computers and Video. http://amiga.resource.cx/photos/photo.pl?id=amilink The short card I have has only 3 BNC connectors - positions 1. 3, and 5, and the long card has only the bottom two. I have another working 2000, so I could replace the motherboard, but I'm not sure I'd gain anything. I have a bunch of questions. I'm not really an "Amiga person", so don't assume any reasonable level of prior knowledge. Where the heck is the video out? I know zip about Video Toaster and even less about the Amilink adapters. All the online documentation assumes I know the basics, like how to hook the durned thing up.... Are there docs for the original VT? Software? I have an OpalVision, with documentation and software. Which is the better board for general futzing around? For animation & graphics? Any docs or software at all for the Amilink setup? Are the SIMMs for the A3001 unobtainium? I have a 33MHz CSI "Derringer 030" in the other 2000, but I don't like the clearance between the top of the accelerator and the drive bay - basically none. Plus, a 50MHz 68030 would be much nicer than a 33MHz. The hardware database page claims that the RAM-32 board needs 4x 1MB SIMMs installed to use the 2 4MB sticks, but this one just has 2x 4MB in the top two slots. Is the database page smoking crack? I haven't seen any pics or mention of the A2000 with the Toaster label on front. I get the impression that this machine is pretty much original - that it wasn't built a piece at a time. Anyone know anything about that? Thanks. Any pointers or help would be appreciated.

[Slightly OT] IBM Typewriter Ribbons

by cb＠mythtech.net

This is probably off topic, but maybe only slightly. I don't know the age of the Typewriters in question. Does anyone need 3 unopened typewriter ribbons for an IBM/Lexmark typewriter. I don't know which model specifically, but the ribbon is labeled as: IBM Easystrike Superior Write Correctable Ribbon #1380999 by Lexmark If anyone has the typewriter these go to and wants 3 of these ribbons, unopened, still in their box, let me know... you can have them (just pay postage, they should be under one pound so it should be really cheap). Also, if anyone knows what typewriter they go to, let me know. I'm curious why I have 3 of them, and maybe if I knew what they went to I might know why they were purchased. They are going in the trash in the next few days, so respond quick if you want them. -chris <http://www.mythtech.net>

Fwd: Seeking good home(s) for old hardware [UK]

My wife is putting her foot down, and frankly I am never going to do anything with it. I am paring down my collection of old computers and peripherals to a few that I will actually use, and trying to find people who will actually use the others. So I need homes for: * SWTPC 6809 computer. Main unit, disk unit inc. 8 1/2" Qume floppy drive, Western digital harddisk controller but no HDD. VDU/terminal (not working). Used to run Uniflex (but I don't have this, since the hard disk crashed and there were no originals provided). I have all the hardware and software manuals. I have seen this computer working but it has been stored a long time. * Remex paper tape reader/writer (works as far as I know, but I don't have the cables for it). * Diablo daisy wheel (have seen it working but about 17 years ago!) It's a long shot, but somebody may be able to help. I can provide more details if anyone is interested. Mail me at jpcc "at" bigfoot "dot" com if you prefer. I am in the UK.

HH drives

by Edward.Tillman＠valero.com

Hmm... If they're FAT16 (2.1Gb max recognition), maybe you can get hold of an old copy of Partition Magic, and see if you can read them with it. Its doubtful that the drives are physically harmed, but the 0 Sector (boot and/or reference sector) will be different with each version of DOS you try. If you can boot from floppy, you may want to reformat the disks (DOS 2.11, or 3.20) and start anew. Do you know what they likely contain? Are they worth the time/effort to recover as-is? Cheers...

Inside this machine (stated built in 1986) were two HH type 5.25" hard drives (one a Segate ST-251 the other not branded but built 1989). On boot up I get: Pheonix 80386 ROM BIOS version 3.53 (c) 1985, 1986 Pheonix Technologies Ltd 640K Base 1408K Extended Memory Hard Disk Failure I have booted the system using a floppy and one drive (the unbranded one) is partially readable. It is a 41Mb drive split into two partitions (primary & extended) - FAT16 system It seems to have been installed with DRDOS. Using my later versions of DOS on floppy I cannot get the drive to respond to any standard commands (I always get a 'Sector not found' error). Can anything be done to revive these disks or were they left unparked and now physically damaged? I have another 5.25" hard drive displaying the same unresponsive characteristics... are they all dead? Thanks in advance Alan

My TTY *does* have a relay on the reader "powerpack" board which can be turned on if an XON (DC3, Ctrl-Q) is sent to the typing unit, and off again upon receipt of an XOFF (DC1, Ctrl-S); it also latches itself on if the reader's manual start lever is flipped, until it is pushed to the stop position, or the tape-out contact opens. Is that the relay to which you are referring? Are you sure the 8/e actually goes to the trouble of turning off/on the reader after EVERY character? At 10 cps that's 100,000 uS between characters (60,000 machine cycles on my 8/L)? Meanwhile I have my 33 apart awaiting new function levers that trigger the above flow-control options (someone had installed Ctrl-B and CR instead of the correct Ctrl-S and -Q). Further reader "tuning" will thus be delayed... -Charles

Or does this >have to be here? The idea is to clear the IER as early as one can to make sure that no interrupts are generated. Since IER and DVH share the same I/O address and are selected by the MSB of the LCNTL, I needs to clear both LCNTL and IER first. Note: the DCR A causes the MSB to be set for the LCNTL that selects the baud rate registers, DVL and DVH. > >> MVI A, 07H ; 8 BIT 2 STOPS >> OUT LCNTL >> IN LSTAT >> IN RX ; CLEAR ANY JUNK >> LXI H, 2400H ; DEPENDS ON SIZE (TO BE DETERMINED) >> LDR1: IN LSTAT >> ANI 01 >> JZ LDR1 ; WAIT FOR CHAR >> IN RX >> MOV M,A >> DCX H >> JMP LDR ; ADDRESS TO BE OVER WRITTEN BY CODE LOADED > >How does this work if the address is two bytes but the code is loaded one >byte at a time? First, the last JMP LDR was suppose to be JMP LDR1 ( my typo ). As long as the high part of the address of the new code to run was the same as LDR1, by writing one byte at a time, overwriting the same high part would not cause the JMP LDR1 to change its action. The next byte to be over written would be the low part of the address. when this happened, the JMP NEW would happen instead. One just need to make sure that the start address of the NEW code has the same high byte. In this case, I can just put it right after the JMP LDR1. It would look something like: Tail end of boot strap: 2328 DCX H 2329 JMP 232A 1E 232B 23 New code to run after load: ORG 232A DW $+2 NEW: New code starts here . . . As you can see, the two will overlap and the final JMP of the bootstrap will be modified to point to the new code on the last loaded value. This is why it is loaded backwards. I should note that Patrick Rigney found one more byte to remove. The sequence: ANI 01 JZ LDR1 could be replaced by: RAR JNC LDR1 Later Dwight > >-- > >Sellam Ismail Vintage Computer Festival >------------------------------------------------------------------------------ >International Man of Intrigue and Danger http://www.vintage.org > > * Old computing resources for business and academia at www.VintageTech.com *

H89 disk transfer program

by dwightk.elvey＠amd.com

Hi Here is the code I have so far. I've shortened it a bunch but I don't think I can get it much shorter. I desided not to use any special Z80 instructions because I want this to work with the H8's as well ( these are 8080 box's but can run HDOS ). It is down to about 42 ( decimal ) bytes. If anyone can remove some more that would be great. I'm using the over writing of the jump address at the end of the code to stop loading and begin using the main down loader. This saved quite a bit of code but it means that I need to load the main loader backwards. This is a pain but not that big of a deal, compared to typing in a lot of bytes. For this code, if someone thinks of some other method that does something like self modifying code, I'm game to that. This is a boot strap and the key is being small. There are no other rules. I thought it would be a good idea to also have the ability in the main loader to save the main loader to disk as a bootable image. This would make it easier because one wouldn't need to keep typing in the first bootstrap loader every time one got more images to load, like a week later.

I will send them in full. > You did mention in your previous post that you > *had* used the term "Islamic Idiot", "although not > referring to Sellam himself." Al, that > was pretty dumb, at best, and malicious at worst. So, you don't think that celebrating the death of courageous Astronauts, and using their death to claim that Allah was against the U.S. and punished it wasn't "pretty dumb, at best, and malicious at worst."? I stand by my comment. I think people who are trying to make this a war against Islam, rather than a war against Terrorists ARE idiots. And what's funny... It's the Radical Islamics themselves who keep trying to drag all of Islam into the fray. I can only speak for me, but I have MANY, MANY friends who are Islamic. And I enjoy the lives and work of many other people who are followers of Islam. And I would reject in the loudest terms that All of Islam is bad. > Especially considering that Sellam is well and > widely known for trumping with the race card, and > for being very sensitive concerning his heritage. That's not my problem. I don't take offense when people talk about Germans, or Italians or Irish. And if you haven't missed it... Two of the three have been major enemies of the U.S. in wars in the last century, and the last one has been the cause of lots of terrorism as well... I don't take any of that personally, as being German, Irish and Italian does not mean I am a Nazi, a Fascist, or an IRA Terrorist. If others can't seperate themselves from what other people do, either they need some help.. Or feel connected in feeings and desires. I can't control either. But, I won't be stifled in my opinions because someone else wants to coddle people doing wrong because their feelings might be hurt. Sorry. When someone does wrong, they deserve to recieve the negative reaction from it. It's how society shows it's displeasure at wrong actions. > > I am posting this to the list so that members can > > observe for themselves the behavior of one of it's > > members... > > We all know how Sellam behaves on list, and many > of us have been exposed to his behavior off list. > I vote "not interested" There's enough crap here > without dragging up more from outside. Ok.. I posted these messages because I want it to stop. I want him to stop doing this, rather than having it tolerated. You say you know about it. How about doing something about it, rather than letting others be attacked and harrassed by him? Because, I'm not willing to just ignore him and allow him to attack others on the list in the future. That's wrong. If he does not receive strong admonishment and feedback that his behaviour is unacceptable (and just letting him go on and do it unchallenged tells him it's ok....), why would he ever stop? He dominates this list and uses it to support his business. He receives a HUGE benefit from this list, that I would not deny him. In return for that, he needs to control himself and treat members of this list with the respect he himself receives. > You know who the maintainer is, if you have a > problem with someone's behavior on the list. You > evidently know also how to contact Sellam's > ISP. If you're being threatened, I suggest > contacting your local LEA. I do NOT know who the maintainer is. Can you give me an E-Mail Address for them? I simply sent copies of Sellam's Email and a complaint to "Postmaster@hisdomain". For all I know, that is he himself, and he got the complaint and is snickering about it... So, posting to this list was an attempt to get others to cooperate in stopping his hate, without resorting to the "LEA" (What is that?) or another Govermental Agency. > But none of what you've posted here is useful here, > and it comes off as simple character assassination. I did nothing to assasinate his character. If reposting his messages does that, that's his problem. I don't post anything that I don't want to come back to haunt me. I certainly don't post messages to people off the list and curse at them, or call them nasty names. OR, falsely accuse them of being racist... LOL! > > Doc Thanks Doc!

How is that the fault of the Bush Administration? If you haven't noticed, his actions have caused the oil prices to start to go back down. Oil prices ALWAYS peak in Winter, and threats of war in the Middle East ALWAYS cause Oil prices to go up, whether the Oil supply is threatened or not. To suggest that Bush leave Saddam to continue to develop WMD's, build up a military to attack his neighbors, and to murder and torture his own citizens is selfish in the extreme. It's a price we have to pay to secure the future safety of the U.S., and the region. > In both cases the perpetraitors are major > supporters (read $$$$) of the Bush administartion.

Why don't you ask the members of this list > how many of them have lost their jobs entirely or > have had to take jobs far below their capabilities > because of the lousy economy and stock market? I have myself. And I lost my good job not because of Action of the Bush Administration (that has only been in office about 28 months... But due to the actions over 8 years of the previous one. To expect the current administration to reverse 8 years (actually 12 years, since Bush 41 made some bad moves as well in regards to taxes and our economy) in 28 months is impatient. Especially considering that 9/11 caused TRILLIONS in damage to this economy. The fact that it is as strong as it still is, and rebounding is a testament to his good leadership. We could be a LOT worse off. I still remember the Carter days.... And this ain't those. Anyone who is slamming this administration for the economy or it's leadership has a very short memory. Our economy has been A LOT worse off in recent memory, and isn't so bad now. And is getting better by the day. The President just made a speech, that should kick the market up a few more points today. I just read an article on the CBS website that says that MOST Americans believe that Bush is doing a good job and the economy today is better than a year ago. That's why I called your post nasty and mean-spirited. Because it goes counter to the data in the world. The data that the economy is improving, and that people say Bush is doing a GREAT job as President. > If you wanted to hear about classic computers then > why did you even reply to this message, why didn't > you just ignore it and go on?

If you took the time to talk to me, rather than making the harsh assumptions you make in the last few paragraphs of your post. You'd find we agree on a lot of things (except your post), and you might even like me (most people do who take the time to get to know me..). I've posted quite a bit in the last few months on computers. But, I'm out of my depth with the major iron that people talk about here. Ask me anything about HP Laserjet II/III, TRS-80's, Coco's (I worked for Spectrum Projects and wrote for Rainbow Magazine), Timex/Sinclairs (I wrote the front end for a lot of Zebra's Products and the manuals), and Mac Emulation... And while I used an Imsai 8080 (with a Z-80 CPU Card) for several years to run a small mail-order business in the mid-80's. I know little about it, as I only used it. I didn't assemble it or maintain it. I can say, it was a nice machine and did everything we asked of it well. I wonder what Stewart did with it? That was at Zebra Systems, Inc. where we made add-ons for the Timex/Sinclair Computers, Tandy Color Computer, Commodore Amiga and the Atari ST computers. Stewart also used to make something called the "Music Box" and "Rhythym Box" for S-100 Systems and the TRS-80 Computers. It was the fore-runner of the Orchestra-80, which Stewart always claimed was a cheaper knock-off of the much nicer Music Box. A minor mod of the Music Box software or Orch-80 Software made them run on the other hardware. I think just a change in which port one addressed with the music data was all...

Fellow classiccmp'ers, A while back, I forwarded an E-mail I'd received to the list. It came from a school tutor who had some questions about Classic-era Apple computers that I couldn't answer. Unfortunately, there was a typo in his E-mail addy, which would have caused any replies to bounce. That typo has been corrected. Here's the message text again. If anyone can help, please contact him directly. Thanks much. Attachment follows. -=-=-=-=-=-=-=-=-=- Subject: ..Hi.........Can you help? Date: Thu, 10 Apr 2003 13:01:11 -0400 From: Randy Sammons <rsammons4(a)attbi.com> Reply-To: Randy Sammons <rsammons4(a)attbi.com> To: kyrrin(a)bluefeathertech.com Hello, Can you help me? I tutor math at a juvenile institution outside of Pittsburgh, Pa. and still use an Apple II E computer(made in 1982). My math program is a very good one...but now down to three 5 1/4" disks which were made in 1984. The software company is long out of existence.(Instructional Communications Technoglogy,Inc.) Do you know of anyone who has three useable 5 1/4" disks?..(my disks say: Apple II (48K) Dos 3.3 Version)..and can my three disks be copied? ..Can these disks be copied to a normal 3 1/2" PC disk? Any help you can give will be greatly appreciated. Thank you, Randy Sammons Irwin, Pa. 724.864.2719 -=-=-=-=-=-=-=-=-=-=-=-=-=-=- Bruce Lane, Owner & Head Hardware Heavy, Blue Feather Technologies -- http://www.bluefeathertech.com ARS KC7GR (Formerly WD6EOS) since 12-77 -- kyrrin(a)bluefeathertech.com "I'll get a life when someone demonstrates that it would be superior to what I have now..."

Newspaper layout/typsetting (was Re: new gifts)

by classiccmp＠crash.com

> They also seem to bear the name of an aftermarket supplier - > Systems Industries?- and some sort of system name, which I cannot > remember, but suggests typesetting. May be the Atex (?) system, which I understand was very popular and is still hanging on in some corners. I've got some pictures around here somewhere from one datacenter of a major metro New York area newspaper showing racks of what I believe are rebadged pdp-11/x4's (they look recent, so maybe /84, /94, or one of the goosed third party CPUs) dedicated to running Atex terminals in newsrooms. The systems are using some reasonably modern storage system - might even be 3.5" form factor. But I wasn't in a position to inspect any- thing too closely. If I run across the snapshots I'll scan them and put them up somewhere for grins. --Steve.

HH Drives ( Wyse Setup & Test Diskette)

by truthanl＠oclc.org

Alan, Do you have a Wyse Setup and test diskette? My employer resold Wyse systems for several years. I 'May" be able to get a version of setup and test. Wyse setup & Test diskettes walk you through configuration. You can enter a drive by "type" from tables, or free form, Cylinder, Head, Sector , entries. Usually when the battery is weak these sytems would forget drive configurations, or even loose track of the Floppy drives. Do you have any identifying marks FCCID # etc on the motherboard, Wyse model, date codes. The wyse bios Part number, (version 3.53 was one of the latter ones). They ran a Wyse Version of MS DOS which, allowed larger cluster sizes, Wyse systems could typically run drives larger the the 528MB. If you can characterize your system a little better I might be able to help Larry Truthan, truthanl(a)oclc.org. Dublin Ohio, USA Digest Subscriber

Mac Classic

by cb＠mythtech.net

>Is there a keyboard shortcut that will turn the $%^& thing off?? Sorry, I said Command-Option-O, but what you may in fact want is Command-Option-X. Command-Option-O toggles CloseView on and off, and Command-Option-X toggles the magnification on and off. I don't remember if turning off CloseView will ALSO turn off the magnification, or if they are two different abilities. In either case, to permanantly disable it, you still should remove the CloseView control panel from the Control Panels folder and reboot. -chris <http://www.mythtech.net>

Help nomenclature???

by Edward.Tillman＠valero.com

I rather thought they used ASCII text, sometimes strained through ANSI for color, but ASCII was the primary character set/map. Cheers...

Data I/O 29A

"Jay West" <jwest(a)kwcorp.com> wrote: > On a more on-topic note, is anyone well versed in troubleshooting/repair of > a Data I/O 29A w/Unipak 2? Mine is sick and I'm not sure where to start :\ Take a look at <http://www.spies.com/~arcade/TE/> -- there are links there to the documentation for the 29A and Unipak 2. Mine seems to think it is OK (passes self test), but it does weird things sometimes, especially when I switch from reading one device type to another. Looks like when I do that, I should cycle power and put it back in remote mode, else the next read will either fail with an error or fail silently by only reading part of the device. So, trust but verify. -Frank McConnell

MC6870A

by aw288＠osfn.org

A while back I offered an old Motorola 6871A clock chip for the 6800 - it went fast. Now I dug up an MC6870A - apparently the same thing, but slower (614.4 KHz). Anyone need it for pocket change and shipping? $3.00 cash gets it to your door. Act quickly, as in ten days I am going on vacation! William Donzelli aw288(a)osfn.org
