That was funny, and even more funnier for computer enthusiasts (I assume we don't call ourselfs computers geeks/nerds? *ducks*). Regards, Andrew D. Burton aliensrcooluk at yahoo.co.uk

Whilst my Amiga's are down at present, I do fully intend to get back to them and develop more games/software for them. All my stuff (so far) is only usually around 200-300KB in size. Without floppy disks I'd have to burn them to CD, or upload them onto the 'net (and then burn them to CD's using a laptop - which I haven been meaning to get for 2 years now, just for that purpose). Whilst we won't run out of 3.5" disks just yet, I was wondering how feasible would it be for someone (probably fairly rich) to make home-made disks? Or perhaps someone would spot the hole in the market and continue to make disks for those of us that require them? The only problem with that is of course, would we be buying enough regularly (200,000 a year?) to make it worth their time/effort/money? I have a feeling it ain't looking good.... Regards, Andrew D.

CBM 8032 Garbage on Screen

by dm561＠torfree.net

--------------Original Message: From: Marvin Johnston <marvin at rain.org> Subject: CBM 8032 Garbage on Screen I've got a CBM 8032 that powers up "fine", but the screen is filled with "!" on every other character position. When some letters are repeated, they can change, i.e. "nnnn" becomes "onon" which seems like (without checking the ASCII charts) that the "n" and "!" are ORed to become the "o". Anyone have any ideas what the problem might be? Most of the schematics I have are buried someplace, so I thought I would start here. --------------------- My guess would be a stuck bit D0 in UC4 (even chars) or UC6 (odd chars), a 2114, notorious for its failure rate. mike

What can I say? The Disk II, either you love it or you hate it. :) To be fair though, the Apple Disk II system was not the only game in town. While they weren't common, you could get a 3rd party 8" MFM floppy system if you wanted to. Would you recoil in horror if I told you that some companies made single sided 40 track 3" (Amdisk) and double sided 80 track 5.25" (Rana Elite 3) drives for use with the original Disk II controller? ;) > I didn't like the Apple ][ I/O system.

Was this an early serial board or were you using the game port? I've always enjoyed the luxury of a 6551 equiped board (Super Serial Card II). I think Woz was allergic to peripheral chips in the beginning. :) > The Apple text display did have lower case (wich the > TRS-80 didn't as > standard), but you couldn't mix text and graphics on > the same part of the > screen.

The TRS-80 graphic characters are pretty neat. The stock Apple character generator was certainly poor in terms of graphics characters. Heck, it didn't have lower case characters! Needless to say, soft hires character generators were a pretty common project. It would have been nice to have had one in the firmware. The hires mode is somewhat byzantine and it was indeed that way to save chips! :) Fortunately, it's not too bad to work with if you use a lookup table to untangle the memory map. I have no doubt it has turned off plenty of people though. The colors are NTSC artifacts! :) I thought that was a neat hack. How did they deal with that in PAL land? > And another oddiity. The whole design of the Apple > ][ > seems to have been > to save a chip if at all possible (provided the > machine still works -- > just). Bingo! Legend has it that Woz's aesthetic ideal was to bum a design down to as few chips as possible. Almost a Madman Muntz I suppose. Methinks you're not a fan of Clive Sinclair either? :) And yet the kayboard was encoded in hardware. > Why? It meant you > couldn't implelement a lower case keyboard in > software > (there are the > well-known shift key mods where you run a wire from > the shift keyswitch > to one of the single-bit inputs on the games > connector, which shouldn't > have been necessary). This is a good point. My guess would be that Woz designed the Apple II as just a naked board, kind of like the Apple I. Apple sold you the motherboard and it was up to you to find a power supply , keyboard, and housing. Apple did offer the ][ that way early on. > Of course I like elegant, simple designs (the HP9100 > is a case in point). > But the Apple ][ seems to have been a case of > cutting > too many corners. > And I had a lot of problems as a reuslt. > > -tony Thanks for your input Tony. While I've never had reliability problems with my ][/ ][+ I think I understand where you're coming from. I like the Apple because I feel it's a machine with interesting capabilities yet made from a small amount of simple parts. It's a machine I can both grasp and enjoy. What's your opinion of the BBC Micro? I've never had the pleasure of using one, but on paper it sounds a lot like a fast Apple II with a pair of 6522, 6845, hardware ACIA, 1770 FDC, and enhanced basic.

I don't know the official release dates for the digital Ampex drives but ICT used them on the ICT1301 which was released in 1962, though the tape drives were not immediately available. These were one inch tape drives (Ampex TM1 I think) and half inch drives (Ampex TM4). These used the aluminium spools with three notches in the hub not the later industry standard expanding hub type spools. The one inch tapes were 16 track and the half inch tapes were 10 track. They used thyrotron valves to fire the pinch rollers. The TM4s also had a version used on the Lyons Leo computers of that era, these used the same tape spools but with a small expanding hub, like a scaled down version of the 7 track and 9 track ones. Professional reel to reel audio equipment used a quarter inch version of the same spools until recently, or maybe they still do for all I know about audio recorders. By the way, as Dr Who has been deemed to be on topic: ICT 1301 consoles appeared on Dr Who and Blakes 7. I think I saw one in a James Bond film too, but I have been trying to find which one but have so far drawn a blank. In the villains HQ there was a big round room on two floors and in the middle were some control panels, the whole place got blown up as is normal in a 007 film. Must have been filmed about the time 1301s were being scrapped 1965 to the early 70s. Roger Holmes (owner of an ICT 1301 for over 30 years)

Lobo Drives made drives for, among others, the Apple II including a neat box with an 8" floppy drive and an 8" hard disk. They were given to me to sell on Ebay, and then the guy passed away (same person who gave me all the Poly stuff, and lots of other things before he died.) I have them set aside until either I have the time to find out more about how to hook it up, or someone drops by who knows what they are doing. My suspicion is that the hard drives probably have a lot of interesting things from Lobo Drives, hence my caution. And I *think* I have the controller card, but again, I need to research this stuff out.

It could make communications software or data logging interesting. There were other disk systems for the Apple though none as ubiquitous. I like the Disk II. I don't think it was the ultimate disk system, just a clever/ cheap one (for Apple at least).

Cool! I'm a pioneer, having collected these things for close to 25 years. Well, I'm not sure I would call it collecting in the normal sense of the word. I want to keep these machines running, useable, and in use. Guess that's why Magica exists (even though she's not powered on right now), along with the other machines at the same site. Johnny

Did anyone catch this Clive "Max" Maxfield article on IBM DeveloperNet some months back? http://www-128.ibm.com/developerworks/power/library/pa-hrrg1 I like his idea of implementing a computer using RS-485 linkup among the functional units. Is anyone tempted to get their soldering iron warmed up? Cheers, Chuck

I like the looks of the Olivetti Underwood Programma 101. It even had two blinky lights: green (solid=ready, blinking=busy) and red (error) http://www.silab.it/frox/p101/boxbig.gif If I recall correctly it was the first computer(*) I programmed. Back in '72-73, while in Jr. High (btw, not "Middle School"). Several interesting things about the P101: Introduced in 1965 (same year as PDP-8). No ICs; all discrete components. The boards were placed component side to component side, designed with one board's components fitting in the spaces between the components of the other board. Programs were stored on magnetic cards, which Olivetti received patents for (HP had to pay about $900K in royalties for the technology use in the HP9100) Its approximate 240 bytes of memory used acoustic delay line technology. Scott Austin (*) Computer? Programmable Calculator?

------------Original Message: Date: Thu, 1 Feb 2007 22:11:24 -0500 From: "Ethan Dicks" <ethan.dicks at gmail.com> <snip> Long ago, I did hang a pair of Radio Shack 7-segment LEDs off of a PET User Port with some trivial logic to use the 8th bit to select digit A vs digit B, then the lower 7 bits of the port went right to the segments. A small machine-language routine tapped into the 60Hz clock interrupt refreshed the digits. For a modern machine, I'd recommend some sort of external latch and multiplexer at least, or perhaps a dedicated LED driver like the ICL7218 (MAX7218?) (here's one I made a while back with 16 digits from one parallel port and two driver chips) http://www.penguincentral.com/retrocomputing/retrogaming/scoreboard.html -ethan ------------Comment: For driving 7seg displays or LEDs, I'd recommend an MC14489; it'll directly drive 5 mux'ed 7 segment displays (hex or pseudo-alpha), straight binary, or 25 LEDs from a 3 wire DC to 3MHz serial interface. Saves a lot of wiring, especially if you use multi-digit displays; just the thing for a blinkenlights panel... mike

Problem with AS/400 terminal

by fireflyst＠earthlink.net

Hi Everyone! I was wondering if any of the CRT gurus here could help me out with a problem I'm having with my Twinax AS400 term. When I turn it on, it's fine. However, it's got a power saving feature that turns off the screen if it goes idle for too long. If this is activated and I try to wake it up by pressing a key on the keyboard, the screen goes crazy like it's got a bad refresh rate or something. The only way to fix it is to power it off and back on, which works every time - the problem with that is, I lose my twinax session, which can deadlock the machine depending on what mode I'm running it in. Any ideas? Julian

You might have some problems with older boards. Minimum revision levels: ZPU: Any 64KZ: Rev J TU-ART:Rev E PRI: Rev E 4FDC: Rev C 16FDC: Rev E IOP: Rev C Quadart:Rev C 128K is the minimum for one user. Each additional user requires an additional 64K with a maximum of 6 users (although you could have >64 ports if you can find room for the I/O cards and connectors). Hard disk recommended for any *real* use. AFAIK Cromix came in 3 versions with numerous revisions: 11 series is for the Z80; AFAIK latest revision was 11.27 20 series is for the 68000 (slooow, use 30 if possible) 30 series (later changed to 1xx, i.e. 153=30.53) is for 68010 and higher, although at least the early versions will also run on the 68000. Note that with some exceptions and depending on the hardware, 20 and 30 series will still run Z80 programs. Also note that the 30 series has provisions to read & write PC & UNIX format diskettes. And of course the languages (BASIC, COBOL, Fortran etc.) were also updated for the newer CPUs. mike

Are there M4 9914 9-track tape driver users on the list?

by glen.slick＠gmail.com

I acquired a couple of M4 9914 9-track tapes drives a while ago and finally got around to trying to do something useful with them. Never having used one before the first thing I did was just see if it would mount a tape ok. The first brand new tape I tried was sucked into the take-up reel ok and wound a few turns, then sucked all of the way back out, then the drive tried again before giving up with a N T U (No Take Up) error. I then tried a second brand new tape from a different vendor and got the same results. Then I went back into the garage and hefted (it's a workout) the second 9914 drive into my work area and tried both tapes on the second drive with the same result. Then I tried manually threading a tape onto the take-up reel while the drive was powered off and making sure that winding the take-up reel caused the supply reel to turn, then powered on the drive and got the same N T U error again. I looked in the manual and it said something about the N T U error occurring due to a lack of tach pulses. Then I looked at the tape path for what might be the tach sensor and guessed it was probably a metal roller near the take-up reel. I used a marker to put a dot on the top of the reel and noticed that it wasn't rotating when the tape was moving past it. I tried rotating this roller by hand and I could feel detents while rotating it and I assume it is attached to some type of rotary encoder. Now to the point posting this here, my questions are does anyone know if this roller/encoder needs any lubrication? If so, how? It felt somewhat stiff when I first tried rotating it and got a little easier to rotate the more I kept at it. And secondly, this roller did have a thin rubber coating which had turned to goo. I cleaned the goo off of the roller. If anyone else has seen this on a 9914 drive (I assume so, it was goo on both of mine) did they do anything about it? Is there a good way to re-rubber this roller? After cleaning the goo off of the tach roller and getting it to rotate a little more freely I did see it rotate when the tape was moving past it (wasn't sure if it would without the rubber) and now the 9914 will mount a tape most of the time. -Glen

TRS-80 Model I

by alhartman＠yahoo.com

I have a HUGE softspot in my heart for the TRS-80 Model I, having purchased a 16k, Level I unit in December of 1978. A unit, I still own today, I hated the keyboard too, even though I wasn't a typist, mostly because it bounced and I had to load a special keyboard de-bounce program to stop it from bouncing and getting duplicate keystrokes. As I upgraded the unit over the years into a 48k Level II unit with several disk drives and a Percom (and later LNW) Doubler, I also upgraded the keyboard. I was able to purchase through Tandy National Parts, the Model III style keyboard that came out on the Model I towards the end of it's run. This also had the added benefit of adding a keypad to the unit. As to the plastic of the case, I guess in retrospect it was cheesy. But, being a kid at the time... It never bothered me. It was certainly no less cheesy than an Apple II or a VIC 20 or an Atari 400/800. Some of the TRS-80 clones got it right I think... The LNW-80 (of which I'm a proud recent owner) and the Lobo Max-80 did a good job of making the computer less toy-like and more business like. The PMC-80 from Dick Smith seemed even more fragile and toy-like, however. As to the hardware design being none too exciting. I wouldn't know, not being a hardware guy at that level. Though, we had used the Dennis Bathory Kitsz book to hop up my Model I with LowerCase, Internal Speaker, Internal Alpha-Compatible Joystick Interface, High Speed (turbo) mod with tri-color LED to indicate Low, High, and Auto (High on most things, low on Cassette and Floppy access). Also, external reset button and composite video for an amber monitor. Computers were fun in those days. I remember applying the zaps from 80-Microcomputing to a copy of Newdos 2.1 to speed up the disk stepping and amazing the salesman at my local Radio Shack at how much faster I could make their Model I boot up. Those were the days... Al Phila, PA

Apple ][ vs.TRS-80

by alhartman＠yahoo.com

In the late 70's and early 80's I think the TRS-80 outsold the Apple II's. Mainly because there were more outlets selling TRS-80's (Radio Shack and Tandy Stores) than there were selling Apple II Computers. But, I can say as a former New Yorker, and a Computer Consultant at that time, that I saw MANY more Apple II's running VisiCalc than I did TRS-80's. The Apple II overtook the TRS-80 and by 1984 or so, the Model I/III/IV was pretty well dead and dying as a platform, while the Apple IIe and IIgs had plenty of life left in them. I loved my TRS-80, but I also lusted after an Apple IIe chock full of Applied Engineering goodies... I never did get one of those, though I have several IIgs machines and a IIc. Al Phila, PA

Just to clarify: 1. These are 40pin DIP Plastic packaged Chips 2. These are CPU chips, not eproms 3. These are not free. We have to pay someone for them. I am doing someone a favor and offering them to people who would most appreciate them. These are the same chips used on the COSMAC ELF. If you are repairing an old unit, or building one of the new clones... You might want some of these. We only have a limited amount of chips. Once these are gone, I can't get any more. Al

Doug Gwyn took my crappy VT11 simulation and extended it to within episilon of passing all the VS60 diagnostics. For a start see: http://www.ultimate.com/phil/xy/ Which shows screen shots of PDP-1 "munching squares" and "spacewar" on a simulated "Type 30" display, one of PDP-11 Lunar Lander... Sources are available thru my CVS server, tho I can't be sure I have checked in Doug's very latest (the vt11.c file in CVS is dated October 2005). We never managed to get it integrated into SIMH distributions, and I don't know off hand the last version of SIMH it did build with. The "display.tar.gz" on the web page is from October 2003(!), and I see there is a source kit named at http://www.ultimate.com/phil/xy/kit2.zip from February 2004. I did a rather "basic" (or "crude" to be less generous) graphics adaptation layer for X11 (polled) and Win32 (starts a seperate thread for message handling). John Dundas contributed an implementation of it for "Carbon" under OSX. There have been several other attempts to add graphics of various sorts to SIMH, including VAXstation style raster display support. John (Dundas) went on to build do PDP-11 front pannel blinklights und switches for SIMH, looks like it's available at: http://dundas-mac.caltech.edu/~dundas/retro/simh/index.html Which says it includes Doug's and my work (in V0.9 or later). But, back to the original topic, I think SUDS needs a PDP-10 (TOPS-20?) system behind it to do the real work. I used to pass the PDP-10 hardware design lab on the way to the Cafeteria at MR-1 (DEC Marlboro(ugh) building one, before the great three letterization that made it into MRO-1). I loved the "rose" program I saw sometimes on the displays, but I don't remember what it looked like anymore... Anyone have the code, or remember what it did? phil

VS60's

by aek＠bitsavers.org

> Umm, and how rare are VS60s these days? Essentially unobtainium. They were expensive and rare 25 years ago. You'd have better luck finding a VT11 or GT40. At least I KNOW people who have those. I've never known anyone in the 30+ years of dealing with DEC stuff who had a VS60. I've been chasing a copy of SUDS for a while. It existed at Stanford, MIT, and DEC. XKL still uses it. The DEC version will probably be somewhere on the DEC LCG tapes. There are bits of it on the ITS tapes that have been released. I'm sure it's on the ones that haven't.

Cromemco Unix?

by dm561＠torfree.net

----------------Original Message: Date: Wed, 31 Jan 2007 19:14:16 -0800 From: Gene Buckle <geneb at simpits.com> Subject: Cromemco Unix? To: General Discussion: On-Topic and Off-Topic Posts <cctalk at classiccmp.org> Odd Cromemco system: http://cgi.ebay.com/CROMEMCO-SUPER-MICROCOMPUTER-VINTAGE_W0QQcmdZViewItemQQ… I've never seen this machine before. I had no idea Cromemco was into Unix. g. ---------------Reply: Nothing odd about it; they'd had Cromix, a sort-of-UNIX available on their Z80 and 68000 systems since around 1980, but by the mid-80s they finally cried uncle and made UNIX systems available with the x20 series, essentially the same S-100 boxes as the older ones, i.e. a 120 was essentially an upgraded System 1, a 220 an upgraded CS-2 (Z-2) and the 320 was the System 3 (8" FD), all with slightly changed styling, a 68010 or 68020 with a 68881, minimum 2MB, minimum 9 ports and an external DC600 tape drive. They also brought out a new CS-400/420 tower version with the tape drive built in. The x00 series were essentially the same systems but running Cromix, although since they were S-100 systems you could put whatever cards you wanted into them and run whatever you wanted, even CP/M or CDOS (their CP/M clone), although with the later CPU boards without a Z80 those programs ran on the Z80 in the I/O processor. I believe there was also a 4000 Mammoth running parallel 68030s on the VME bus, although I don't have one and have never even seen one. I've got two of the 420s sitting on my verandah gathering snow; wonder what the cold'll do to the infamous rollers in the tape drives... I could dig out some old price lists if anyone's interested in the available models. mike

MCA RAID card, Vaxstation, Sun SCSI boxes: free to a good London home

by david＠cantrell.org.uk

I'm having a clear-out of a load of old stuff that I'm no longer using (or in some cases acquired and never used). Of interest to this list: * MCA SCSI RAID card, Mylex DAC960M, known working about four years ago. no driver disks, no box, no anti-static bag, no cables, no nothing. * VAXstation 3100, not powered on since I acquired it. external SCSI cable. * miscellaneous Sun external SCSI boxes which might even have working disks in 'em. All free to good homes. New owner to collect in south London, or I can deliver the MCA card in central London. I won't ship anything. If you want any of it, please contact me by private email. Anything not gone by the end of the month will be thrown away. And somewhat off-topic, if anyone knows where I can get a DVI-to-SCART converter so I can attach a Mac Mini to a TV, do please let me know. -- David Cantrell | http://www.cantrell.org.uk/david fdisk format reinstall, doo-dah, doo-dah; fdisk format reinstall, it's the Windows way

And of course we had all the drawings for the machine. And we were always trying to get someone to donate more stuff to us. And of course, my school at the time used a PDP-11/70, and at nights I was hanging out at the nearby university, where they had a whole bunch of DEC-10 machines on which I could get guest accounts. By 1986 I got my first two PDP-8 systems home. Almost wish I was back in those days. So much fun. And some really odd hardware was still around and possible to get your hands on...

Jules Richardson on arty computers

by c.murray.mccullough＠gmail.com

I quite agree some classic computers have an internal beauty but some have an external beauty that is almost art-like. My vote goes to the Coleco ADAM as it's beauty lies both in its internal/external construction. What is deeper than that I'm not sure...! Happy computing! Murray :)

speed of vintagecomputermarketplace

by marvin＠rain.org

First, the obvious - the speed that something sells is a function of both price and demand AND visibility ... just *had* to get that out of the way :). But what you are asking is not an easy question to answer since there are so many different variables. Visibility I fully agree that VCM makes a really good venue, and Sellam's rant seems to be having the (unintended) effect of more people listing and viewing the site. One of the reasons I *really* would like to see a link to VCM from ClassicCmp.org is that I can easily publicize the ClassicCmp listserver on ebay emails, the "About Me" page (although it hasn't been added yet) without worrying about the two faced retaliation by Ebay. Some of you may recall the Ebay notices to put out the information to all the newsgroups, etc. about Ebay and that helped a LOT to publicize the site; word of mouth about a good thing was *very* prevalent. This is also what needs to be done to help publicize the VCM site. How Long I've had things on VCM for maybe a year or more that 1) haven't sold, 2) finally sold, and 3) sold quickly on Ebay. Things like books are relatively easy to research pricing. There are other research tools to help determine pricing on relatively common stuff, but things that are less common are basically an educated guess and are set by how fast you want something to move. It is also helped/hindered by how well/poorly the listing copy is written. > From: David Griffith <dgriffi at cs.csubak.edu> > > I'm attracted to the idea of listing as much of this as I can at the > vintage computer marketplace because 1) the people who buy stuff there > presumably know what they're buying and 2) I can easily list stuff and let > it be for sale until it's sold.

Correct. > RSTS (c. > 1980) simply rotated half a dozen or so "on" lights. No no no. RSTS/E had a really cool pattern. They had two "snakes" running around across the data and address lights. That was a real trick. Appearantly they pulled that off by having the idle loop actually run in supervisor mode, which wasn't used by RSTS/E at the time, so they could control the address that way. Rumour have it that they had to drop that piece at RSTS/E V9 or if it was V10 when they finally started using supervisor mode more seriously in RSTS/E, but I haven't seen the RSTS/E idle loop since V8 so I couldn't really say. > Others have described > RT11's pattern. I never saw a light pattern on an '11 running Unix - > perhaps they were never idle? Was the concept of the idle-loop lightshow > unique to the PDP-11, or did other systems with data lights implement them? I can't remember any idle pattern when running 2.11BSD on an 11/70 anyway. The machine was idle sometimes, so maybe they just didn't implement anything fun. But I'm not entirely sure my memory is on par here. They might have had a simple rotating pattern on the panel. It's been a few years since I last fired up Unix on a PDP-11. Other machines have probably also done idle patterns, but in the PDP-11 rumour have it that the different OS groups were competing with each other on who could do the coolest idle pattern. I believe most agreed that RSTS/E won. Johnny

speed of vintagecomputermarketplace

by dgriffi＠cs.csubak.edu

As some of you may know, I have Rlee Peters' collection of stuff, which seems to be largely composed of documentation. So far, I've been unloading it on Ebay. The recent discussions about Ebay versus the vintage computer marketplace got me thinking. I'm attracted to the idea of listing as much of this as I can at the vintage computer marketplace because 1) the people who buy stuff there presumably know what they're buying and 2) I can easily list stuff and let it be for sale until it's sold. Does anyone here have a ballpark idea of how long stuff would sit there until it gets sold? As I picture in my mind's eye the two storage units of stuff, I think I might have been a little too eager to get it. Oh well. At least I have some vintage items that I wouldn't otherwise have. I'm keeping about four cubic feet of stuff. The rest I need to find a home for. -- David Griffith dgriffi at cs.csubak.edu A: Because it fouls the order in which people normally read text.
