An interesting 3 hours on PBS last night:
- 'Steve Jobs - One Last Thing': No description necessary.
- 'Long Distance Warrior': McGowan/MCI's David & Goliath battle with AT&T
and disastrous merger with Worldcom.
- 'Digital Man/Digital World': Ken Olsen/DEC's growth and ultimate decline.
(No doubt everyone here except myself had already seen this one ;-)
Interesting comparison of the different styles and personalities of three
men who profoundly influenced the tech world of today and their companies.
Thoroughly enjoyed it.
This might be a tempest or shielded vaxstation? Anyone speculate or
know for sure.
The vendor may have these mixed in as equivalent to their other
vaxstations. If you search for "DEC vax VS42A-BN"
you end up back at the vendors listing for the ones with plastic
covers. I didn't turn up any info yet, not hoping to.
but the thing has what appears to be optical, and a huge connector which
may be shielded SCSI on the back.
I can't tell from the front, but there may be a hatch to allow it to be
opened and a floppy inserted, not sure from
Kind of an interesting device.
I looped back into the vendors listings to this auction for the plastic
topped version, by the way
It is badged VT-1300 so may not be a vaxstation. And the other box may
be one of the VT-1300's
that is tempest or shielded.
I bought the Tek 4051 on ebay today; Jason brought it to my house and it works perfectly, with about a half hour of programming instruction my 12 old daughter was plotting a cat face.
I would like to get in touch with other users of this first personal computer, and find additional resources.
Do you know where I can find an archive of BASIC programs for this?
Has anybody built plug in cards in the back, mine came with a realtime clock and a "file manager", I do not know what that one does.
I have some Tek scopes with IEE-488, and I will see if I can get the IEEE interface working.
There was a DC300 tape in the machine:
The belt is broken in the tape, I have ordered some new DC300's and will transplant the tape.
Any resources will be welcome!
I'm actively working on show planning for VCF PNW and I'm noticing that we
have a few international travelers planning to attend and exhibit their
machines/projects. I'd like to put together a FAQ for the logistics of
traveling with vintage equipment across the US border. If you have ideas
please let me know.
For example: Should I plan on providing letters in advance stating that a
person is a registered exhibitor at our show, including details like the
show location, dates, times, and contact information in case there is a
question about why somebody is carrying strange looking equipment into the
US? Is there any sort of paperwork or customs form needed even if nothing
is being sold or left in the US? Any other gotchas to look for?
I hope this is vintage enough.
I've been playing around some more with my projects to create VMs /
bootable USB keys with PC DOS 7.1 and DR-DOS.
Right now I'm focusing on DR-DOS 7.1 and the DR OpenDOS Enhancement
Project, because that's FOSS and AFAICS it can be redistributed, which
I can't with DR-DOS 7.02/7.03/7.04/7.05 or DR-DOS 8/8.1, which were
I found a download of the last build released:
First, it's the wrong size. VirtualBox can't mount it. VMware can.
I truncated it to exactly 2880 sectors using the advice from ``jleg094'' here:
VBox mounts that. But it won't boot, nor in VMware -- it just
displays 2 dots and freezes.
Embarrassingly late in the troubleshooting process, I've found why.
I didn't think to check what was on the image! Foolish of me.
I mounted it on a pre-booted VM and looked, and it's blank! There's
nothing in the image at all.
So, I mounted the empty image file as a loop device, copied the boot
files in there and then the rest of the files in the distro archive.
And lo, it works! It boots my VM just fine, and it's now running 7.01-08.
All I need to do now is work out how to make the hard disk bootable,
and I'm in business.
The DR-DOS 7 SYS command won't do it, as the files aren't named
IBMBIOS.COM and IBMSYS.COM -- they're DRBIO.SYS and DRSYS.SYS.
I copied them to the expected names. SYS completes but the disk won't boot.
Next step will be to try with Norton Disk Doctor.
Anyway, if anyone wants a bootable diskette image with DR-DOS 7.01-08,
complete with FAT32 support -- apparently it can even boot from it --
let me know.

I have a microvax set up with VMS 5, running MULTINET (and decnet
locally). The server has a FQDN and after a while being exposed to the
WWW someone out there started using the server as an SMTP relay. I can
disable and clear the queue, but I'd like to block entirely this from
happening in the first place. I'd like to learn more about how this
happens in VMS.
Anyone have had this same problem before? I realize back when VMS 5 was
current it was not so much of an issue, but today it is. I am working on a
solution. I can envision a few ways including blocking the smtp relay port
>from the firewall, but if possible I'd like to set up a VMS Multinet
solution as a learning exercise.
I am open to suggestions, and once I find the solution I'll post it.
I understand that this kind of thing is not cookie cutter, there are
different levels one could address something like this. I have a comcast
business router, and one of the 5 IPs I have is NAT assigned to the
internal 10.1.10 port of the microvax.
This is the same machine I wrote about previously as with then, thanks for
your help. I find the best way to learn is on the actual hardware warts

The 180si does not use DIP switches, so I can't help with that. The Tech Ref manual does have Command Code and Character Set info, however. The whole manual is a bit over 100 pages. I can scan it if you are interested.

The 180si uses one also. It "catches a spray of ink which the printer uses to clear the printhead cartridge before printing." A new pad is included in each printhead cartridge container.

I have been working on a HP 2640B terminal. It was mostly about fixing the
"screen mold" problem and cleaning up the liquids that had been seeping out
>from the screen down into the bottom.
The small coaxial wire that connects the 4.9152 MHz clock signal form the
power supply (never seen a crystal controlled SMPSU before!) to the
backplane was broken off, but after fixing that the terminal worked fine.
Just needed some adjustment to the brightness.
With the correct terminfo installed it worked quite well as a serial
terminal to a Linux box.
Then I tried the short 8008 programs that Christian Corti pointed to
I tried both a couple of times. The terminal enter the LOADER mode but just
hangs completely at the end. I tried different baudrates but no difference.
The selftest STATUS line tell me 40<802 which should indicate that there
are 4k memory in the terminal. However there should be 5k since there is
one 4k board and one combined control store and 1 k RAM board. Maybe there
is a fault in the 1k SRAM? The terminal doesn't complain though.
Regardless, the programs listed either starts at adress 30000 or 36000
which should then be within the available space.
The question is, should these program work for the HP2640B as well? It has
a 8008 but my guess is that the firmware is different from the 2644. What
is the joint experience regarding this? Has anyone ran these small programs
above on a HP2640B?
The HP 2640B firmware consists of four EA 4900 ROM chips which annoyingly
are not anything like normal EPROMs. So dumping will need special
Has anyone dumped the HP 2640B firmware already? I didn't find it on
I just picked up a Kodak Diconix 150 Plus portable inkjet printer. No
power supply or documentation, but it works fine. It appears to be a
variant of HP's Thinkjet (it certainly uses the same cartridges) tweaked
for portable use. Looking inside, it's full of Chinon ICs, and was
apparently made in Japan (from the baseplate).
This one needed some parts on the DC interface board resoldering, but
after that it worked fine.
Which brings me onto my question... Does anyone have any information on
I'm mainly looking for a DIP switch table (annoyingly, it won't produce

on the control codes, emulations and character sets it supports.
Also - does anyone know what the material on the printhead capping
station is, or if they're still available?
It looks like a cardboard or blotting paper pad with a plastic backing
card. This one is soaked in ink and looks like it could do with being
replaced. I assume it's to stop the cartridge from drying out?
