I'm a bit unclear on how this new list setup is supposed to work, so my apologies if I've sent this to the wrong list or in the wrong manner. I have a couple of systems for sale in York, PA. I don't want to ship. Email me if you have questions or want to make an offer. Preference is given to people buying more and taking it away sooner. SparcServer 470 Power supply has problems and the cards are stuck in too tight to get them out with the plastic tabs (IIRC, I broke one of the tabs). Nice chassis, though, and aside from the PS, the cards are probably good. Similar to <http://shidahara1.earth.s.kobe-u.ac.jp/shidaharaimage/ workstation2.gif>. DEC 3000 800 This is pretty nice. No keyboard or mouse, but it appears to power up and you might be able to get a terminal working with it. It has an Alpha (RISC) processor and I'm [i]told[/i] 256 MB RAM. The hard drive is something like one or two gigabytes and is supposed to have a BSD installed with the password set to something generic like "password". This was going to be the new Applefritter server but I got fet up with trying to get a terminal to work with it. Looks similar to the two towers in <http://images.google.com/images?q=tbn:A8Idr5_kU7MC:www.rz.uni- wuerzburg.de/system/pix/wrzx1415.gif>. DEC 3000 something-or-other This is pretty junky but might have some good parts. Free with the DEC 3000 800. Looks similar to <http://www.g-lenerz.de/images/dec3000-front.jpg>. Altos 3086 This was made into a CAD system by Slice. This is a pretty cool looking setup, has a big drawing tablet, and a huge stack of manuals. Information on the Altos: <http://www.aurigae.demon.co.uk/works.html>. This also comes with a generic PC or a terminal, or something along the lines of that. If you need more details on any of these systems, let me know. Apple Macintosh LC 580 Working and includes ethernet card. I have a couple of these. Things I'm looking for: Apple and Mac clones Neat Apple stuff Amiga 1000 keyboard Whatever I need to get my Altos running (the catch is I don't know what I need yet, though I'll definitley need software for it on 8" disks) Tom Applefritter www.applefritter.com

EXABYYE 8500 + Peripheral Vision card

by dave＠naffnet.org.uk

Hi, I have an EXABYTE 8500 drive with a Peripheral Vision daughter card plugged into the back (along with the LCD display on the tape door) - I am taking a guess that this card provides hardware compression to the 8500, but, without documentation, I am not sure how to configure it. The board has six DIP switches, numbered 1-6 from right to left as you look at the rear of the drive. 1-3 are the SCSI address, and seemingly must match the SCSI address that was configured on the drive itself - fair enough! Switch 4 enables a menu allowing the selection of 2 and 5GB modes, and I understand from googling that, if I was to have a 8500c then I would also be able to bypass the drives internal compression from here. Once more, this is so far perfectly reasonable. All of which leaves switches 5 & 6, the reason for this message - can anyone tell me what (if anything) they do? Many thanks, Dave.

It should accept or reject the <spamtest> address and then allow the RSET to reset the envelope. If that's consistent behaviour, and you want to run the rest of the tests, you'll need to find out what they are (or devise equivalents) and do each by hand. Some of them have to be run from a non-local connection, so you might need an accomplice. http://www.sxlist.com/techref/inet/smtpsend.htm has a sample transcript if you want to try individual tests by hand. BTW, there is one shortcoming of the tests -- they check to see if the mail is rejected at the time of the SMTP exchange; some people have argued that it's OK to accept the mail so long as it's not delivered. Personally, I prefer not to have some spammer wasting my resources and I prefer the mail to be rejected at the earliest possible point. -- Pete Peter Turnbull Network Manager University of York

Suggestions for Raw Tape Reading Under Linux?

by vonhagen＠vonhagen.org

Hi. I've been trying to read in a variety of old backup cartridge tapes as raw data so that I can write some tools to parse them (or port the old backup software used to write them). This seems to be the easiest way to explore old backup data from a variety of old machines without having to fire up the machines themselves. Since I'm trying to do this from a Unix (Linux) box, 'dd' was the obvious first choice, but I don't know things like the block size at which the tapes were originally written. Ideally, I'd just like to read raw data from the media, period. I've tried reading the tapes using 'dd' with a variety of block sizes, but still get zero-length input files. The drives I'm using to read the data are capabable of the densities at which they were written, and I understand the Unix/Linux device numbers - you can hear that the drives are working at the correct density, but I'm still not getting data. I even wrote a little program to just read data directly from the raw device, but don't seem to be getting anything there either.The drives whir and whine, but I get nada. Any suggestions? Any utilities you'd suggest rather than 'dd'? Many of these are non-Unix systems, so 'tar' and 'cpio' aren't appropriate. Thanks! Bill

WTB: VAXstation

by mrbill＠mrbill.net

I'm looking to buy a halfway decent VAXstation (3100, or preferrably something like a VLC). One requirement - it needs to have the 15-pin graphics monitor connection on the back, so I can use this BC23K cable to connect to the VRE01 I got today for $5. 8-) (Yes, I'm buying a computer to hook to a monitor, not the other way around!)

Um, no, I'm afraid it means your SMTP software bombed. It failed to go to the reset (initial) state after the second test, so the test sequence was aborted, and the remaining 16 or so (?) tests weren't carried out. I wouldn't trust that software just yet... I think the next test would have been something involving a message ostensibly from the "<>" address (which represents the mailer daemon), and then some tests involving forged addresses intended to look like your own domain, and then assorted routed or malformed addresses. Some of these are very important, and your site hasn't been tested for most of them. -- Pete Peter Turnbull Network Manager University of York

[CCTECH] Altair Assistance Request

by classiccmp＠mail.vintage-computer.com

Hello all, I am relatively new to vintage computing and this list, although I've been working and playing with computers for a long time. I am, however, a software guy and have only a little skill with or knowledge of hardware. I've recently acquired a pair of Altair computers (8800 and 8800a) both equipped with the "88-DCDD" single 8" disk drives. Unfortunately, I am having various difficulties with these machines. Hopefully the answers to some questions will push me towards a better understanding of these systems. My main issue at the moment revolves around the EPROM cards that hold the disk boot loader (DBL) PROMs for these machines. The cards are Solid State Music ?2K/4K? cards with 16 slots for 1702s. I asked the list about these cards before and have since obtained an assembly/instruction manual, but it is still unclear to me how these things are configured and addressed. There are four address switches which are supposed to address the board as follows (this is taken from the manual): Address: 000 000 to 017 377 - All switches on 020 000 to 037 377 - A2, A3, A4 on 040 000 to 057 377 - A1, A3, A4 on 060 000 to 077 377 - A3, A4 on 100 000 to 117 377 - A1, A2, A4 on 120 000 to 137 377 - A2, A4 on 140 000 to 157 377 - A1, A4 on 160 000 to 177 377 - A4 on 200 000 to 217 377 - A1, A2, A3 on 220 000 to 237 377 - A2, A3 on 240 000 to 257 377 - A1, A3 on 260 000 to 277 377 - A3 on 300 000 to 317 377 - A1, A2 on 320 000 to 337 377 - A2 on 240 000 to 357 377 - A1 on 360 000 to 377 377 - None on I see issues with this from the outset. First, assuming this is octal, the addresses past 160 000 are beyond the address space of the 8080 chip in the Altair (200 000 being 64K). As well, the gap of 16k at 160 000 to 200 000 is either an error in the manual or something I am missing since I can?t imagine the binary progression of switches having that gap. How is this card addressed? I?ve tried examining my way through the memory areas that I think are supposed to be addressed into the EPROMs (based upon various assumptions) but I get results that have me confused. Answers to some of these questions might help: Why would the address lights on the Altair not properly correspond to the address switches being set? If I set the switches at 1110111000000000, for instance, when I reset then examine the light at A11 doesn?t come on (the lights show 1110011000000000) even though I know that LED to be functioning. Why would the data lights ever show anything but on or off? I sometimes get dim glows from the data LEDs. What data can I expect to be in the RAM on boot-up? Is this answer different for Static vs. Dynamic RAM? What is the best way to execute the boot loader should I locate it? Can I set the address switches to the proper spot and run or do I need to code a simple program that will ?JMP? to the known address? Much of my confusion might stem from the EPROMs themselves since they may have been erased by time. I have a freshly burned set on order which may help. Please forgive my ignorance and this really long post. Thanks in advance, Erik _______________________________________________ cctech mailing list cctech(a)classiccmp.org http://www.classiccmp.org/mailman/listinfo/cctech

[CCTECH] Altair Assistance Request

by labomb＠rochester.rr.com

Hello Erik, Tony's response to your post was right on. I would like to add that the MITS boot eprom must be located at 177400 (or FF00H) to work correctly. So in your case, all switches should be off to locate the card at 360 000 to 377 377 (F000 to FFFF) in the last 4k block. The DBL eprom should then be in the last socket (highest addressable socket) of the eprom card. Once things are configured correctly, you should be able to set the front panel switches to FF00, hit 'Examine', and then hit 'Run' ... at which point the drive should enable, the head should load, and then an attempt to read the boot tracks (0-5 is typical for MITS software) should proceed. Best regards, Scott

E&S PS-390

by pat＠purdueriots.com

I saw a pair of Evans & Sutherland PS-390's (small end table sized) down at Purdue Salvage today. I was wondering if they had any value... I saw a few cables for them and keyboard and a digitizing tablet, but no monitors. Drop me a line if anyone wants one. I should be able to get them for somewhere between $50 and $100 for it all (both of them + accessories). Also there were several binders full of stuff. At a minimum, I'm gonna get the manuals for them... -- Pat

VAX 11/780 powered up and going :-) only a little :-(

by gunther＠aurora.regenstrief.org

Hi, finally I got around branching off a power line from my 220V 60A dedicated computer power circuit :-) I have all three phases of the VAX connected to a single 110 V phase. Matt, I fiddled with the fuses and found that I had to have F1 and F2 connected or else more than half of the outlets would habve no power. This whole power distribution and interlock system is still a mystery to me, does anyone have schematics for it? What worries me is that the key switch seems to have no effect whatsoever, it doesn't provide any more or less power, and throwing it from OFF to LOCAL doesn't effect any reboot attempt on the console system. Anyhow, I can get to the console and do some @140200G and indeed the RX01 starts klicking and up comes the console program. It tells me that the WCS and FPLA versions mismatch, (0E-xx vs 0F) but that isn't fatal, I gather. Then I did a TEST with the MIC diagnostics floppy and that runs through sections 01 to 07 and then has an error to report with module M8234 (PCS CPU PROM CONTROL STORE, as I gather.) The appropriate course of action would be to call DEC field service and replace the board, I guess. Too bad. I suppose the trick with replacing the M8234 will be the PCS version. I noted that if WCS and PCS versions mismatch, that would be a fatal error to begin with. That means it will be extremely hard to replace the PCS, or won't it? Could one do anything to repair that PCS? I suppose so, but not if one has no idea what's wrong with it. Any advice? Back in normal console mode, I tried to do a BOOT anyway, just to see if that PCS problem may be not that bad. But that's a no go, it comes up to a failure pretty quick. Could be that it's just because the default boot device isn't there, but it's too quick with the error. So, that will be a more difficult start then. But I guess I'm still lucky because at least I can get to the MIC diagnostics at all (poor Matt.) But of course one wonders what else might be broken? Is there a way to copy console floppies? I noticed some serious bit rott, as only one out of three standard console floppies actually worked. I guess it's about time to back up the good ones before they go too. thanks -Gunther -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org

With the switch down (the normal position) the console is on MMJ-0 and a <BREAK> on the terminal will be ignored. With the switch up MMJ-3 will be used as the alternative console and <BREAK> will halt the system. As far as autobooting goes, that's not dependent on the switch setting - it depends on the console settings as stored in NVRAM. I think this is pretty much the same for all the MicroVAX 3100 systems. It is also true for all the VAXstation 3100/4000 systems except (as you note) with the switch down the graphics head is used as a console and not MMJ-0. Antonio

Chip-8 questions

Hey, Cosmac people -- I'm working on a Chip-8 emulator for, natch, the Commodore 64. There is a nice instruction set listing at http://users.aol.com/autismuk/chip8/chip8def.htm but it doesn't well document how the carry in register vf is used. For example, does 7rxx use the carry even though it doesn't set it? What about 8ry4 or 8ry5? These set it for borrows/carries but do they use them in the addition or subtraction, like the 6502 ADC/SBC? Also, what does 'skip' mean? Skip the next instruction?
