For those with 6809 experience

by brain＠jbrain.com

Looking at the datasheet for the 6809 (specifically, the 6809E that needs incoming quadrature clock), I read that !HALT can be asserted 200nS (for 1MHz part) before falling Q and the CPU will finish the existing instruction and then go into a HALT state as long as the HALT line is low during the falling edge of Q. That's the store from the datasheet, but when I am testing it, I see that, even if I pull HALT low at the very beginning of the last cycle of an instruction, the 6809 will not acknowledge the HALT until executing the next instruction. My logic is watching for IO address $ff61.? When found, it drops Q so, to start the HALT condition, I need only: lda $ff61 Not that the trigger is being performed by the code, so the current instruction (the lda) should complete and then the CPU should go into HiZ.? What I see is: lda $ff61 lda $ff60 <- the next instruction executed, and THEN the CPU goes into HiZ. I can deal with this (Yes, I should just look at BS=BA=1, which tell when to safely use the bus, but I don't have access to those signals for this project), but I thought I'd see if this was known by all, or if there is something I am missing.

SWTPC 6800, FLEX and Percom Floppy

by deramp5113＠yahoo.com

Now that I have my SWTPC 6800 loading and saving programs with paper tape, cassette, and floppy disk (using the Percom LFD-400 controller and their MiniDOS and MPX ?operating systems?), the next logical step is getting FLEX up and running. Unfortunately, I only have the Percom floppy controller and I don?t know if FLEX compatible disk drivers and boot code were ever written for it. Before I go create Percom support for FLEX from scratch, does anyone have any leads? Mike

Wang 2200 Diskettes

The floppy eject button was then closest to the operator and any disk inserted would be visible from the "rear" of the floppy. Not nearly as weird as the Altos ACS8000, for example, that mounted the floppy drives upside-down and horizontally, such that the eject button was topmost. Those disks do have content labels placed on what we'd consider the "backside" of the floppy for obvious reasons. Did any 5.25" floppy-equipped systems do this? --Chuck

What is this System 360 peripheral/maintenance console?

by steven＠malikoff.com

I was watching this video on highway construction in the 1960's (as you do) and noticed what appears to be a System 360 console, that I couldn't place. Presumably it's some peripheral or CE maintenance panel. I didn't find it in the Physical Planning Guide (not that that's comprehensive) nor from perusing google images. I'm a little curious as to what it is. It's at 23:13 in https://youtu.be/apWSa6QlrTg?t=1393 Thanks Steve.

They are located in the Apple/Macintosh category. https://docs.google.com/spreadsheets/d/19vhF-o6vx9g7l-D8cvLJ5OPJzpdmU9PTTkn… Unfortunately for you, sale is pending on the SE/30 NIC. If the sale falls through, you are in line behind one other person. I'm fairly confident that even if the first buyer falls through, the second in line will not. If you're still interested in the other accessories, I can have a look when I get home, get a few pictures put up for you, and we can continue from there. International shipping should not be an issue, filling out a customs form is not very hard. Best Regards, Joe Zatarski

TOPS-20 networking

by athornton＠gmail.com

*TOPS-20* The set of config files you need to edit in TOPS-20 is found here, about halfway down the page: http://www.ldx.ca/notes/tops-20-notes.html I'll paste it here: Configuring the system The *Panda Distribution* README has this to say about initial configuration: You?ll need to edit the following files. EMACS is installed on this system, along with TECO and EDIT. [More on these editors later.] SYSTEM:7-1-CONFIG.CMD to set your timezone SYSTEM:HOSTS.TXT to define your local host name and network SYSTEM:INTERNET.ADDRESS to define (again!) your IP address ? must be the same as in klt20.ini. Also define your netmask here as LOGICAL-HOST-MASK SYSTEM:INTERNET.GATEWAYS to define your IP gateway SYSTEM:INTERNET.NAMESERVERS Don?t bother with SYSTEM:INTERNET.NAMESERVERS. That is the configuration file for DEC?s resolver; although it?s simpler it has some interoperability problems with MMAILR which haven?t been resolved yet. SYSTEM:MONNAM.TXT to define your system name DOMAIN:RESOLV.CONFIG to define your DNS servers, your default domain (replacing MYDOMAIN.COM) and any users in addition to OPERATOR who can send control messages to the resolver. To actually edit any of those, you'll probably need to ENABLE first, eg: @ena $ The dollar-sign ($) prompt indicates that your privileges are enabled. *Linux Host* On the host side, I like to convert my ethernet to a bridge so I can add virtual interfaces easily. Here's the script I use (requires sudo, and that the user running it be in group adm, and that the tuntap devices be owned by and writeable by group adm): #!/bin/sh eth0text=$(/sbin/ifconfig eth0 | grep "inet ") HOSTIP=$(echo "${eth0text}" | awk '{print $2}') HOSTNETMASK=$(echo "${eth0text}" | awk '{print $4}') HOSTBCASTADDR=$(echo "${eth0text}" | awk '{print $6}') HOSTDEFAULTGATEWAY=$(/sbin/route -n | grep ^0.0.0.0 | awk '{ print $2 }') # Change as we add more guest OSes with network stacks _maxtap=2 # for i in $(seq 0 ${_maxtap}); do /usr/bin/tunctl -t tap${i} -u adam -g adm /sbin/ifconfig tap${i} up done # # Now convert eth0 to a bridge and bridge it with the TAP interfaces /sbin/brctl addbr bridge0 sleep 1 /sbin/brctl addif bridge0 eth0 sleep 1 /sbin/brctl setfd bridge0 0 /sbin/ifconfig eth0 0.0.0.0 /sbin/ifconfig bridge0 $HOSTIP netmask $HOSTNETMASK broadcast $HOSTBCASTADDR up # set the default route to the bridge0 interface /sbin/route add -net 0.0.0.0/0 gw $HOSTDEFAULTGATEWAY # # bridge in the tap devices for i in $(seq 0 ${_maxtap}); do /sbin/brctl addif bridge0 tap${i} /sbin/ifconfig tap${i} 0.0.0.0 done For some reason this seems to work even though that should be group netdev. I guess because "adam," who is running the emulator, owns the tun/tap devices. I have this in /etc/udev/rules.d/99_net_tun.rules: KERNEL=="tun", GROUP="netdev", MODE="0660", OPTIONS+="static_node=net/tun" I don't think that's standard; I think I added that at some point. And then in klt20.ini, I have a statement that looks like: devdef ni0 564 ni20 ifc=bridge0 ipaddr=192.168.248.249 dedic=false And then finally the dnpni20 executable is setuid root. All of this together gives me a TCP/IP stack on klh10 that allows the emulator to run as me, not as root, and bridges the TOPS-20 host into my real network. Adam

Panda TOPS20 networking trouble

by dave＠661.org

I'm having loads of trouble getting networking going with the Panda Distribution of TOPS20 and KLH10. Could someone point me to a step-by-step guide on doing this? -- David Griffith dave at 661.org A: Because it fouls the order in which people normally read text. Q: Why is top-posting such a bad thing? A: Top-posting. Q: What is the most annoying thing in e-mail?

He must be selling something himself and had a similar subject line. That said, no hits on my post yet? what, nobody needs nubus ethernet cards? or various ISA/PCI/PCI-X expansion cards? a dozen computer mice? DEC Alpha 4100 RAM? some nice combination SCSI/fastethernet cards? OK, I get that it's mostly junk ;), but no attention at all so far. Keep checking, getting more stuff in the list every day. I added a recent section so people can keep up on the recent additions without having to check the whole list. As before, I'm in the west suburbs of chicago in case anyone is local and sees some stuff they want.

Wang 2200 Diskettes

by jgeorge＠nbi6.com

I bought some 8? diskette cases and they arrived with a bunch of old software for a Wang 2200 in them. One of the boxes HP was badly water damaged, and the diskettes are shot, but those look like backups of some company software. Diskettes that look like they may still viable include 2 marked ?WANG 2200 MVP Operating System v2.6.2? and one marked ?2200 MVP (Multi-user) BASIC-2 System Platter Release 2.5?. There?s also a box of diskettes of what look like source for something ?GBS Mod 1 Diskette Version?. I?m not a Wang person and I can?t use these diskettes for anything, does anyone on the list have any interest in them? Is the software worth rescuing or is it already archived somewhere? If anyone wants them, drop me an email off list. Gimme a couple of bucks to cover shipping and I?ll send you all the ones that look viable. Joe
