Birthday gifts for the computer collector

by mmcfadden＠cmh.edu

My wife has made the mistake of asking me what I wanted for my birthday. Most of the suggestions I could make she wouldn't be able to understand or find. This led me onto a thought process about the ideal "computer play area". Insulated 20' X 20' room one wall entirely covered in shelving raised floor extreme airconditioning oversized chair with U-shaped table for work area power strips everywhere tools for anything phone to call and order more "stuff" refrig for food and drink no need to sleep Enough money to buy any classic computer I desired and no interruptions for work or chores. These were the last thoughts I had as I drifted off to sleep. Maybe I'll work on this dream a little more tonight. I've heard that some prisoners develop an alternate world with activities that keep them sane. Mike

Needed: HiRes scans of an Altair 8800b front panel

by bob＠jfcl.com

Does anybody have an Altair 8800b that they'd be willing to disassemble and scan the faceplate? That's all :-) Or maybe somebody has already done this? I'd like to find a nice high resolution scan of the 8800b front panel if I can. Thanks, Bob Armstrong

Help! SC/MP Programming Question

by river＠zip.com.au

Hi, I have a small issue with printing out the ASCII char set, from $20 to $7E inclusive. The 8251 initialisation is okay 'cos I ran a small program to print a single char to the TTY and it worked fine. So, I thought I'd expand on this to transmit the printable ASCII char set to the TTY (actually, Hyperterm). However, it jusat transmits spaces. I've tried a few variations and it never prints the chars properly. I'm figuring that there is a problem with my logic, but as I don't have a SC/MP programming manual and I can't see the forest due to the trees, I'm hoping someone here on this list with some SC/MP programming knowledge maybe able to offer some assistance. The P1 register is pointing to the 8251 data port, and 1(1) points it to the control/status port. ktest: ldi $20 ;First char is ASCII 'space' kt1: xae ;temp save in E-reg/exchange the A and E regs kt2: ld 1(1) ;get UART status ani $01 ;Tx Ready? jz kt2 ;No, keep checking lde ;Yes, get char st (1) ;Tx the char scl ;carry = 1 adi $00 ;add 0 + carry xae ;save to E reg lde ;move back to A reg xri $7f ;gone too far? jz ktest ;yes, start at SPACE again jmp kt1 ;no, print it Basically, I load the A reg with ASCII $20 (SPACE) and save it to the E reg. Then I check the 8251 TX Ready flag and when ready I get the ASCII char from the E reg and transmit it. The char is still in the A reg after the transmission, so I set the carry bit and add $00 (ie incrementing the A reg). I then save this value in the E reg and then load it back to the A reg - thereby both A and E regs have the same value. I then check if I have hit the end by destroying the A reg with the XRI instruction. If I haven't hit the end ($7F) yet, I go back to "kt1", whcih relaods the A reg with the char and then it goes on to print this char. If it's at the end then it goes back to "ktest" to start back at ASCII $20 and does it over again. I've done this heaps of time with the 8080 processors and don't know why it's not doing it with the SC/MP. Also, I have some SC/MP listings about and one of them has "LD @0(P2)" instruction. >From what I know, and this maybe totally wrong, the "@" is an auto-increment/auto- decrement bit and you must specify the displacement for the inc/dec. If this is the case, then what does the "0" that immediately follows the "@" do? I would expect to see a value other than "0" to ensure the P2 register is inc/dec by the appropriate amount. Please, old SC/MP dudes, any help would be greatly appreciated. river

Dssi Cables

by williams.dan＠gmail.com

I might have asked this on here before a while back..... But does anyone on here have any dssi-->hsd cables. I've got a storage rack which has the potential to be 12x9gb scsi storage for my vaxcluster. But I have the wrong cables. The cables I have go between (I think) 2 hsd devices. I need a couple of cables to connect to a 4000, can anyone help. Thanks Dan

My Amiga 4000T has arrived!!!

by zmerch＠30below.com

It got dropped off this afternoon -- Now I actually have to learn about the durned thing... ;-) It's SCSI (of course) with a 2G hard drive & CD-ROM reader ( I have a 2x burner that may work well in it...) -- it has an S3-Virge based VGA card with what appears to be 2 outputs; it's weird as it seems to be a 2-piece card with one interface on each card, and each card plugging into 1/2 of a Zorro slot (At least that's what I assume they are...) and the cards have a small bridge-cable between them. It might be a CyberVision 64/3D based on the description of that board, but I'm not sure, as it has no picture. It's got the stock A3640 processor card, but I do not know the speed of the CPU as it's got a heatsink on it -- I'll have to spark 'er up when I get a chance, but that may not be for a couple of weeks or so... All the RAM slots are full, so it would prolly have 16Meg onboard (I'm guessing) - but no extra ZorroIII boards for memory... It also seems to have some onboard video with a DF?23P but no monitor or anything - I'm assuming they did not use that video port. Other than the VGA card, it seems stock or nearly so - most slots are empty, it does not have a network card or modem... ... And Holymygoodness, the sucker's not even ontopic! It was made by "QuikPak Corp." and was made in January of '98!!! :-O So, if you're gonna whack me on the 10-year rule, just unread this message back to the beginning and forget you opened it. ;-) Laterz, Roger "Merch" Merchberger -- Roger "Merch" Merchberger | "Bugs of a feather flock together." sysadmin, Iceberg Computers | Russell Nelson zmerch at 30below.com |

Obscure DOS question

by micheladam＠theedge.ca

How about using a later version of DOS, and having it masquerade as 3.3 if need be? The version being reported to a program by the OS can be changed on an individual program basis for compatibility purpose, so you might remove the 512 file limit without too much hassles. I beleive MS DOS 5 and up have this facility. I certainly remember using it for some AT&T STARLAN drivers way back...

Sun 4/330 with faulty serial interface...

by dave04a＠dunfield.com

>> Erm, no the serial/parallel conversion isn't common to both ports >> on the chip. > >Hmm... curious. I'd downloaded the datasheet for the chip and it wasn't >clear either way so figured I'd try the inverter trick. > >> This implies that some buffer chip that feeds to 8530 is >> faulty. > >If they are totally seperate channels (no common internal buffering >first, say) then yep, it looks that way. There's no buffers immediately >by the serial logic, so I'll look further afield. Even though there is (obviously) separate parallel/serial shift registers inside the chip for each channel, I am assuming that the parallel data bus enters the chip through only one set of pins - it is entirely possible that the input gate, or some internal buffer common to both channels has failed. An easy test would be to trigger on chip select, scope the affected data bit on the bus inputs, and write patterns to the chip with the affected bit in both hign and low positions - it should be very easy to determine if the data bit is making it to the chip or not. If yes, replace the device, if no, move to the next upstream component and repeat the test (all the while keeping triggering on the device chip select). It should be a very easy matter to identify the defective device in this fashion - no need to remove anything other than whatever device is defective. Even if you don't have an extender board, it is far easier to tack a lead on to points you want to test than to be removing and replacing entire devices in the hope of being lucky. -- Just MHO.

Visiting Bristol UK

by huw.davies＠kerberos.davies.net.au

Can anyone recommend some Classic Computer related things to do near Bristol UK? I'm flying in from Australia in early April for some training but I'll have at least one weekend to kill so any suggestions of things to see near Bristol (I'll be without car which will be an interestingly enough concept in itself!). At the risk of upsetting the OT Gods, if anyone in the UK can recommend a cheapish, reliable ISP that I can dial into during the stay, a personal e-mail with some detail would be appreciated - the company approved hotels don't have broadband available.

another hp2100 wannabe

by Tim＠rikers.org

Hello list. I signed up and did the confirmation but did not yet receive a join msg. I presume the moderator will have to approve this msg. My first exposure to computers was using an HP TSB system. I'm interested in at least trying to get this going in an emulator. I started a wiki page on my progress: http://rikers.org/wiki/FirstComputer Seems most folks used 2000A on a dual cpu 2100S setup with dial in terminals. Our setup was not like this. The computer room had a 3 terminals hooked up to an HP-2114 series machine. I'm not sure about which model, but the front panel looked just like what I see in online pictures like: http://d116.com/vcf/east/1.0/hp2114a.jpg There were 2 crt terminals that each had 5k of working space. I seem to recall that the card reader and teletype had 2k or 3k each. I'm not sure if that was bytes or words. Perhaps it could have been an hp-2114c running ACCESS 2000E? I saw a post about the manual being available: http://www.classiccmp.org/mailman/htdig/cctech/2004-July/032447.html and the the E series system works: http://www.classiccmp.org/mailman/htdig/cctech/2003-November/022100.html Can someone hook me up with the pieces I need? I'm currently running SIMH with the hpbasic (basic1.abs) image. There are things that are missing like "DIM A$[100]" does not work on that version. On our setup with the single 2114 box, we did not have to login. Everyone shared the same disk storage area. I don't recall anyone having a username at all. there were just the 4 (2 crt, tty, and card reader) terminals. I recall folks kept forgetting to clear the current program before typing in a new one and then getting a mix of two programs. I don't recall the commands, but it seems to me you could be on a crt and tell the system to read from the card reader, then run a stack of cards and the program would be loaded into your memory intead of just being run and output to the printer. I do recall that stored files that started with an "!" were hidden from listings. I think there were 2 disks. One that was removeable and one that was not. They were locked in the cabinet and never removed. On another topic, since BZFlag is now over 10 years old, Does that make it Vintage? ;-) Are all you SGI folks using it? I have an old Indy here (IP22, 8bit) which I've been meaning to get it running on, but I'm missing OS CDs, compilers and such. If anyone can help out, that would be nice. ;-) -- Tim Riker - http://rikers.org/ - TimR at Debian.org Embedded Linux Technologist BZFlag maintainer - http://BZFlag.org/ - for fun!

Bell + Howell IDB 2000

by classiccmp＠ultra-gonzos.de

Hi folks, I recently aquired a Bell and Howell IDB 2000 system with three workstations. The boot/data CDROMs (9) came with it. It seems that it is an early network computing system. The computing power is in the workstations, but they do not have any drives. They have to boot from the fileserver. The fileserver starts up but the workstations won't boot. I hooked up a laptop with a sniffer software into the Bell and Howell network (standard Ethernet). The workstation sends a kind of request (propietary, not even TCP/IP) but does not get a reply. I hooked up a serial terminal to the console of the server and got a menu system. The interesting menus (system administration, configuration etc.) are protected with a password. The password has to be standard because the server boots from a pressed cdrom. Does anybody have expieriences with these computers? p.s. One of the worksations has the label Siemens EPC 2000, but looks the same as the Bell + Howell. best regards Flori

Silent 700 connector pinout?

Fw: PDP-11 Emulator

SunOS 4.x boot disk layout

by julesrichardsonuk＠yahoo.co.uk

Does anyone happen to know the organisation of a SunOS 4.x hard drive? Looking at the disklabel under Linux, I get the following: | Disk /dev/sdb (Sun disk label): 15 heads, 131 sectors, 1701 | cylinders Units = cylinders of 1965 * 512 bytes | | Device Flag Start End Blocks Id System | /dev/sdb1 0 48 47160 0 Empty | /dev/sdb2 48 152 102180 0 Empty | /dev/sdb3 0 1701 1671232+ 0 Empty | /dev/sdb4 152 264 110040 0 Empty | /dev/sdb7 264 1701 1411852+ 0 Empty (ignoring the 'empty' - think that must be a bug in Linux fdisk as I know there's a valid OS on the disk) Googling shows the first entry to be the root partition on such a drive, second entry to be swap, third to be the whole disk entry, and the rest to presumably be aux partitions... However, obviously some space is taken up by the partition table itself, so the first (root) partition can't start at block zero. What I'm trying to find out is the offset that it does actually start at, so that I can mount the root partition from Linux. Hopefully someone knows, if not it's trial and error time... :-) ta Jules

Apple 9500 Power supply

by bpettit＠ix.netcom.com

Someone recently asked for an Apple 9500 power supply. Who - and do you still need it? I saw a 9500 at the bottom of a pile in the garge today. Don't know what kind of shape it is in, but think it was working when last powered up. Billy

Starting over with 8" drive on PC

by vcf＠siconic.com

Ok, starting over here since there's been a long hiatus since the last time I messed around with this. I'm experimenting with different 8" disks trying to figure out what's going on. First, the basics: I know my controller can handle FM because I was able to successfully copy all the files off an old 160K PC disk in my 1.2M 5.25" drive. Second, the 8" drive can successfully format/read/write an 8" drive when I have the BIOS configured for a 5.25" 1.2M drive. My drive is a Tandon TM 848-02. Someone e-mailed me a link to the manual they scanned, and now I can't find that person's e-mail nor remember who it was (I'm so sorry!) But at any rate, of the 3 measley links that come back from Google, I see that this drive is DSDD. Still don't know if it can do FM however. I have some 8" disks in both CP/M and DOS 2.11 format from my NEC APC. They both read fine on the NEC APC. I'm trying to read targeted sectors using debug. With the CP/M disk, I try to L 0 0 0 1 (Load at address 0, drive 0, sector 0, 1 sector) and get: Not ready reading drive A Ok, so I try L 0 0 1 1 and after a longer pause get: General failure reading drive A Hmm, I'm still new to this, but this seems like a density issue. Tried on the DOS 2.11 disk and got the exact same errors on both read attempts. I formatted an 8" disk under DOS, then tried L 0 0 0 1 from debug and successfully load the sector into memory. What's interesting is if I try to read sector 0 from the NEC DOS disk and get the "Not ready reading drive A (Abort, Retry, Fail)" error, then immediately put in my known readable formatted DOS disk and hit R)etry, I get the same error ("Not ready reading drive A"). If I abort and then retry, it works fine. Or if I wait at the Abort, Retry, Fail prompt for a little while then retry, it also works.

The SC/MP... it lives!

by river＠zip.com.au

Hi, I've got a few old SC/MP-II chips and I decided to try and do something with them. It appears that only 2 of the chips actually work, but I've just proto-typed a small system with 4K ROM, 4K RAM, an 8251 USART and an 8255 PPI. I got the comms going yesterday and the PPI is fine. Excellent old vintage stuff. I forgot how cumbersome the SC/MP instruction set was, but it's fun trying to code around its deficiencies. I've got a listing of the original KITBUG for the SC/MP, but I'm going to expand on it to provide more functionality. I'll try and base the monitor off the old Intel 8080 SBC monitor. When she's all done then I'll wire-wrap it onto a single board and put it in a nice display box. I like these things to work, as opposed to collecting chips to sit and gather dust. This brings me to a question. Does anyone know any chip brokers that sell a small number of chips to hobbyists? I've tried a few but they seem uninterested in selling small numbers and to private buyers. I don't understand this 'cos I doubt there will be orders for thousands of old chips like the SC/MP from businesses - and rather then sit and collect dust at least the brokers could sell some of their stock to private buyers. river

Reset switch for IBM 5150/5160?

by trixter＠oldskool.org

Has anyone ever wired up a reset button/switch for their IBM PCs? I find myself powering down-then-up my 5150 three times a day when all it needs is a hard reset to reboot a hung machine. I've searched the web and usenet archives for such a design or specs but haven't found anything. If I could soldier a few wires to a pushbutton, I feel like I would less harsh to the machine... Or, does it not really matter? Is it not a big deal to power down, then power up (after 5 second delay) a 5150 or 5160? I know IBM PCs were built well, but I am unwilling to find out *how* well :) -- Jim Leonard (trixter at oldskool.org) http://www.oldskool.org/ Want to help an ambitious games project? http://www.mobygames.com/ Or check out some trippy MindCandy at http://www.mindcandydvd.com/

SIG/M diskettes

by marvin＠rain.org

I just took a look at the SIMTEL arechives on the Walnut Creek CP/M disk, and they appear to have all the disks (judging by the directors) up through volume 310. Take a look at: http://www.rain.org/~marvin/sigm.txt if you want to see what has already been saved from the SIG/M archives. For some reason, I can't ftp the sigm.txt file and the amount that gets transferred before it chokes varies each time I do it. The txt file there currently has most of the listings but is missing some stuff at the end. But in any case, it appears that what you have has already been saved. If you do take a look at the list, note that there *are* some typos in the list. > I just received some 8" diskettes that I "won" on e-pay.

Some said they have CDOS and Cromemco disks

by dm561＠torfree.net

That would be yours truly; I had sent you a note off-list but didn't get a reply. I've been copying/archiving some of it in PC format and sending it to Randy for his Cromemco archive/museum (see his reply yesterday), so contact him or me off-list & we'll see what we can do. Note that Cromemco had at least 6 different (more or less [in]compatible) OS's which may or may not be useful to you depending on what cards you have in that Z2 (although CDOS is more or less the lowest common denominator). Also, as Randy mentioned, if using PC-DOS format images, you may have trouble with the oft-discussed FM/MFM issue. mike -------------------------Original Message: Date: Sat, 26 Mar 2005 00:15:35 -0500 From: "Curt @ Atari Museum" <curt at atarimuseum.com> Subject: Some said they have CDOS and Cromemco disks Hi, Some recently mentioned that they had a significant amount of Cromemco software, if that person would be willing to allow me to make dup's of their disks I would appreciate it, I have a CP/M system with both 5.25" and 8" disks on it so I can handle reading both types, I have a Z2 that I'd like to get up and running again and I would really like to get copies of CDOS and any Cromemco specific utils, thanks.

Totally OT, but frustrated.....

by dvcorbin＠optonline.net

Apologies up front. I have a (potentially) wonderful PDP-8/e with TU-56 and RK05 just begging for attention (as soon as I can get ONE of my ASR-33's to behave properly). I WANT to spend time on that machine. I also have and sbc-6120 I want to get OS/8 up on for the MARCH show. Still the "real world" makes demands. Yet another weekend supporting (gasp) modern systems. But some of the things that strike me are..... It STILL takes the same amount of time for a system to boot.. It STILL takes the same amount of time to format a disk.. It STILL takes the same amount of time to install a (basic) OS It STILL takes the same amount of time to customize the OS ..I can keep ranting... Amazing, the more things change.the less they do.. [I KNOW the original saying is different]. Thanks again David..

Not sure it this is what you're looking for, but here is the service manual for the TM 848-2 - perhaps this is the same as the "02": http://www.bitsavers.org/pdf/tandon/TM848_service_1982.pdf

Reset switch for IBM 5150/5160?

by dave04a＠dunfield.com

>Find the 8284a (82284 in the AT) timer chip in the PC. When pin 11 is >shorted to ground momentarily it will start the reset process. Also >shorting the "power good" line from the power supply will do the same >thing. The power good pin is supposed to be P8-1. I recall at one time having an original IBM PC/AT with a reset switch wired to ground the "power good" line. It worked fine, and was still working when I got rid of it ... I don't know if all power supplies would tolerate this - might be a good idea to put a small resistor in series with the PS output so that you are not shorting it directly.

RGB on VGA monitor

by Saquinn624＠aol.com

If you have a decent monitor, the sync on green should not be an issue. Older Macs and many workstations (SGI, all 3w3) run sync-on-green. If you do a search on "connecting PC monitors to SGIs" or similar it should tell you known monitors that work SOG. In any case, it's probably much cheaper to find a used monitor that supports SOG than to buy a box. Sony's monitors are a good bet (have 2, one OEMed by Radius, one by IBM, both work Sync-On-Green. -Scott Quinn

SIG/M diskettes

by dmabry＠mich.com

I just received some 8" diskettes that I "won" on e-pay. I was only buying used SSSD diskettes, but when they arrived they contained files. They are SIG/M #81 through #120 and #161 through #176. My question is this. Are these files already archived and preserved for the "community" or should I spend some time (lots of time, actually) and get the files to a CD or something similar so those of us who are interested in CP/M history have them? I don't mind doing it, but I don't want to spend this time if it is already done. Thanks, Dave Mabry Intel MDS tinkerer

Annex Terminal Servers...

It has reasonable security so my eventual aim is to have it accessible from the Internet, for much the same reason you want to hook up your Vax.

The Annex Term > server is working fine on my local subnet, however for some reason it > will not talk across from a remote system on another subnet through my > firewall/router... You probably don't have all the configuration set up. I have the manuals, about 9" of shelf space, and the remote management software. You don't actually need that management software, but it does make life easier. My guess is that you don't have the gateway address (and/or subnet mask) correctly set. I assume you know to use the "su" command from the CLI to the superuser prompt, then the "admin" command to get to the admin mode, and "show annex all" (etc) to see the configuration? You need that to set the subnet mask (and many other things). You don't set a default gateway like that, though. The annex uses its routing table for that, and you can either set a static route using the "route" command or by putting the route(s) you want in the "gateways" section of the config file which it loads when it boots. You can display the routes using "netstat -r" and "netstat -C". After I compiled the software, I corrected a few of the manpages and wrote a few extra ones, which I'll send you by private email. In the meantime, here's a few useful URLs: http://www25.nortelnetworks.com/library/rannex/relnotes/R10.1A-Release_Note… http://www.ofb.net/~jheiss/annex/ http://lost-contact.mit.edu/afs/net.mit.edu/project/afs32/andrew/netdev/sun… -- Pete Peter Turnbull Network Manager University of York

Free, I'm scrapping tape drives

by trash3＠splab.cas.neu.edu

I am getting rid of my 9 track tape drives. All drives are Cipher 880, 890, or 990. None are SCSI. I have one Kennedy I promised to ship to England. I also have 4 formatters for the older style drives. It is all going in the dumpster. If anybody wants it, let me know and we can make arrangements for you to pick the stuff up. If you need more info, let me know as well, off list. Oh, yes, one is a Cipher 910640, which is the upright style, the others are all the pizza-oven style. If I have forgotten and already promised some of this stuff to certain people, now is the time to speak up! Any manuals that I had are still with Al, but they may be on bitsavers by now.
