Altair 8800b + drive alignment

by adavie＠mad.scientist.com

I recently purchased an Altair 8800b from the original owner. He told me that last he used it (1984?), he was having trouble reading from the disk drive, and he was sure that it needed alignment. Apparently an alignment disk is required. I suspect an oscilloscope as well. I have two questions; 1) Can someone explain the process of aligning a disk drive, what is out of whack, and how tricky it is for a rank electronics amateur like myself 2) Where can I obtain an alignment disk, if required. Oh, I forgot to mention, the drive is an 8", the Altair model that has the same basic case and look of the Altair itself. This repair is one of the (I suspect) many that will be required to bring the Altair back to life. I've managed to get it (almost) firing up during the self-test stage, but one of the address lines doesn't behave (the light doesn't come on on A2 when I flick the switch that should light all of them, yet the light is operational at other stages). I'll get to that one later. Looks like a long, slow process. But worth it, no? Cheers Andrew

Altair 8800b + drive alignment

by adavie＠mad.scientist.com

The manual/documentation I have gives a procedure you can follow (manually flipping the switches all the way) which is a self-test. Following the procedure you can check if your 8800b is working correctly. Using this procedure I tracked down several problems (loose wires to fron panel) but still have the address light problem. I'll track down the procedure and explain further, if there is any interest. I appreciate the comments about the alignment problem, and can see how basically I should be concentrating on the Altair first. So thats what I'll do. More soon.

The stuff will run on an altair but the IO which is personalized for my NS* with it's two serial ports. there is no way I can personalize it for the altair as I have no clue of the IO (serial boards used and their addreses). The NS* motherboard (backplane) has two serial ports and a parallel port plus a few other useful things so their configurations were easier to be certain of. You need to track down a set of NS* manuals or copies. FYI: NSdos requires a minimum 16k of ram starting at 2000h it does not use ram below 2000h (or care). Also it assumes the ports start at 00 and the port devices are 8251s with hard jumpered baud rates. If you are going to configure an altair you need manuals, more manuals and it doesn't hurt to be able do digital design to understand what they did. You see the docs with early altairs were not amoung the best. Most of what you may need to know often had to be extracted from the printsets by understanding the logic. then you have the non-altair boards plugged in that manuals are very handy for too. If the boards require extra or specific software (some terminal interface or video display boards) the hadware and software manuals may be needed. Allison

Altair 8800b + drive alignment

<1) Can someone explain the process of aligning a disk drive, what is out <whack, and how tricky it is for a rank electronics amateur like myself It's tricky as you will need a good scope and the alignment disk and know how to use both. also getting the alignment disk after so many years will be a challenge. <Oh, I forgot to mention, the drive is an 8", the Altair model that has th <same basic case and look of the Altair itself.

But worth it, no? Shouldn't be that bad. the altair 8800B was a later machine and far better/different than the 8800 or 8800A. Of the Altairs it was the industrial strength version. What will help your task is having documentation (a must for any old machine!). It wouldn't hurt if you have a techie near you that is familiar with old s100 hardware as a PC kid genius would not have a clue. Allison

ah yes, the first ps1 series to come out. i presume its a 2011-c34 or m01. you might want to try this trick: with the machine off, press and hold down both mouse buttons, then power on. when it posts, let the buttons go. that will force an autoconfig, and make it boot from rom again. that trick works on all ps1 models. you shoulda made your disk backups when it was running, but too late now. you can still order the core software from ibm. i think it's ~$45. ring the helpcentre at 800.772.2227 david In a message dated 98-02-03 16:55:21 EST, you write: << I recently came into possession of a PS/1 model 2011.

Actually, I've jammed the $^\&* things a few times myself. The solution (that I've come up with) is get a screw driver, (flathead) and then push it up and straighten it out. I've done the same thing with IDE connectors. I used the same solution, but instead of trial and error for getting them strait, I would get it straiter, then put an IDE cable into ONLY the damaged area, straiten it out a bit, see if it works, then try again. >But it's not a simple ENOUGH solution because, when I'm in the field and >detaching a monitor from its computer, 50% of the connectors I look at have >one pin bent in an L and jammed against the inner wall of the shell.

I'm not saying we don't need 15 pins; I say we need >15 THICKER pins, and since this connector is typically the only connector >on the back of a VGA adapter, there's plenty of room. Why not move away from this type of pins all together? Sure, it would cause major monitor incompatibility, but VGA type connectors are aging rapidly, and with new LCD monitors, the SVGA interface is reaching it's limits. Maybe something like a ethernet-type connector, or, as you said THICKER pins. Maybe switch the male-female part of this, with female-connector monitors. And, re-align the pins so that you can use a correctly configured (with the M-F type connectors, etc.) EGA, or CGA monitor. >Coming Spring '98: The Windows 98 Bible by Kip Crosby and Fred Davis! ^^^^^^^^^^^^ Keep me updated.

CP/M conversion

Looking for Melbourne collector

by adam＠merlin.net.au

Hi! I was just offered (possibly at a small cost - we didn't discuss any prices) a very large collection of Atari computers (800, 800xl, etc), plus manuals, books, software, peripherals and everything else you can probably imagine. However, I already have four Ataris of different sorts, so I thought someone else might appreciate it more (although, if you do, I may be interested in a couple of items *grin*). Anyway, as the collection is in Melboune I thought it might be of the most interest to a Melbourne collector, and I don't know any. Is anyone interested? Let me know and I can pass the phone number on to you. Adam.

The format are: Tek Hex ASCII Hex Space Binary Motorola S Rec Intel Std & 8086 Elan Fuse Map Jedec Mos Tech Texas Tags Also any specifications for the above formats would be much appreciated.

Visual Basic for DOS?

by maxeskin＠hotmail.com

It is my understanding that there was once a (Microsoft?) Visual Basic for DOS. Was it like VB for Windows, and was it any better than QBasic?

greetings / my collection

by adavie＠mad.scientist.com

Hello to the list members. I've just joined you. Based in Australia, I have Altair 8800b (don't ask the price!) Kaypro II (found today - $30) Exidy Sorcerer x 2 ($25) Ohio Scientific Challenger 1P board (free) Dick Smith Wizzard (aka. CreatiVision) ($10) Sinclair ZX80 ($1) Sinclair ZX81 ($1) Sinclair Spectrum (trade for a slide rule) Atari 800 + 810 (well my Mum has it, but I'm working on that) Although not a big collector of the older computers, I am in general an avid collector of smaller computing devices such as slide rules and calculators. I'd like to announce my web-sites on these subjects... Museum of Soviet Calculators http://www.comcen.com.au/~adavie/slide/calculator/soviet.html Slide Rule Trading Post http://www.comcen.com.au/~adavie/slide/ My intent in joining, however, is to share my resources (boxes of software for Exidy Sorcerer - but I can't load any of it - no working drive!) and perhaps utilise the brain pool of this list to help me get my Altair up and running, and also enable my Kaypro II to boot to anything but <System?> I also have manuals for about 10 different Kaypro packages - email me for list. In any case, I was pleased to accidentally stumble on this list, and fervently hope it is still an active one. I do welcome private communications, but would generally prefer discussion on the list for the benefit of all. Cheers Andrew Davie

I don't know what the various failure modes of an LK201 look like (none of mine have failed), so I can't say offhand what's wrong with the keyboard. I would first try swapping it (since I have plenty of them lying around) and, failing that, going for a serial console. Also, the ? on 7 indicates some sort of problem with the disk controller.

CGA Modes (Wuz: Win 3.0)

by Philip.Belben＠powertech.co.uk

>>Is it some kind of "Super CGA" that wasn't really supported by anyone? > > I know some game companies "tweaked" certain memory registers or something > so that standard CGA could do 320x200x16 colors, but as far as I'm aware, > there was only 320x200x4 and 640x400x2 for CGA, 640x400x16 for EGA, and of > course 320x200x256 for MCGA. (The latter was what my Compact IBM PS/2 Mac > wannabe had) I never heard of 320 x 200 x 16 for the CGA - I seem to remember 160 x 200 x 16 - surely it would not have had the memory for the other? The CGA never did 640 x 400 x 2 that I ever heard of - I assume that was a typing error for 640 x 200 x 2. The EGA did 640 x 200 x 16 on a CGA monitor, 640 x [was it 400 or was it 350] x [a number of colours dependent on the memory installed] on an EGA monitor, and even did 640 x 350 x 3 (I think) on an MDA monitor. I also once saw a demonstration on a CGA card that changed colours in real time faster than the scan rate and so gave more colours than you'd expect. But I digress. What was the question again? :-) Philip.

CPM86, GEMDOS, GEM Files - Whole free systems

by mallison＠konnections.com

I'm sure everyone knows about this, but for the few, such as I: For a bunch of CPM systems, 68k, 8080, Z80, Z180, CPM-86, MPM, checkout: http://cdl.uta.edu/cpm/download.html They have it all including CPM-86 OS + C compilers, Basic Compilers, Fortran and Pascal. Plus the same for CPM Z80 & 8080 system: Plus, the Digital Research Library with GEM stuff for Atari and DOS, including GEM Desktop, Draw, Write, and GEM Publisher You could have a good 8088 or 8080/Z80 or Atari system, for just a little time. -Mike

Well, it seems that I need more explanation. I was wondering if this would be a more resource-conserving way to do it, and technologically easier. I would do this with network cards if I had them. Serial ports might be good, as well as parallel. Is there a way to make the computer do TCP/IP via serial or parallel port?
