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.

Happy DEC-10 Day!
It is my honor to announce that we at Living Computers: Museum + Labs
are releasing to the computing community our Massbus Disk Emulator
and all the associated software. This device connects via Massbus
cables to the RH10 and RH20 interfaces on KI-10 and KL-10 systems, to
the RH11 interface on KS-10 and small PDP-11 systems (including the
front end 11/40 on the KL-10), and to the RH70 on the PDP-11/70. The
MDE provides up to 8 emulated RP06 or RP07 disks (represented by disk
files in the format used by the SimH emulation of these systems).
We expect that it will also work with the RH780 on the VAX-11/780 and
VAX-11/785 although we have not yet tested it in this configuration.
The original MDE was designed by Keith Perez in 2005, and emulated up
to four RP06 drives connected to a KL-10. The current generation was
a redesign by Bruce Sherry in conjunction with the restoration of our
DECsystem-1070 in 2012, and initially provided eight RP06 drives on
the RH10. It has undergone continual development, with associated
software created for us by Bob Armstrong, and is now being opened up
for the use of the relevant communities.
To this end, we have placed the design files for the hardware and the
source files for the software to interface with it, along with our
library of Universal Peripheral Emulator routines, on public access
repositories at Github. The URLs for these repositories are
https://github.com/livingcomputermuseum/MDE2https://github.com/livingcomputermuseum/MBShttps://github.com/livingcomputermuseum/UPELIB
These are released under a very liberal license which will allow for
free use of the MDE by any interested party.
Happy Dec-10 Day!

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
the photos.

Kind of an interesting device.
I looped back into the vendors listings to this auction for the plastic
topped version, by the way
VINTAGE-DEC-DIGITAL-VT1300-VAXSTATION-VS42A-BB-COMPUTER-SYSTEM-VT-1300-TERMINAL/
http://www.ebay.com/itm/370912245260
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.

Hi,
I am working on several projects requiring 2708 and 2716 EPROMs, and
am finding some of my chips will not erase, and some will not take
a program. I've also learned more in the past week than I wanted
to know about repairing Data-I/O 29a/b programmers.
I vaguely remember in the 1990s baking such EPROMs in the oven, but
I do not remember temperature or time. I was surprised that Google
didn't turn up anything useful with this info.
I'm sure someone here will have some notes on EPROM baking.

Is anyone perhaps interested in any of the following?
It's essentially the remainder of some of my earlier offerings.
I took the time to provide some details (that previously may
have been missing)
I intend to clear out the majority of it by mid-December
(around the 15th), after that it will likely be hauled off
to the recycler.

Since I know there's tons of PDP/11 geniuses here, and other gurus with a NOVA 4, and a Tektronix 4052 guy (I have the 4051):
What have you done, with microprogramming this part? In your architecture, have you changed the microcode, create an instruction to enhance your machine?
I would be interested in any hardware projects, stories (or even in the FPGA, I hear its a popular thing to copy);
I read all of Donnamaies pages, and planing to hook up, breadboard the eval kit, perhaps reproduce the PCB if you guys are interested.
What about the coding tools? ADASM? Looks long gone, how do you do microcode today?
If I forget the soldering iron, can anyone show me an example on a Xilinx board, ISE, Vivado that uses the original AMD 2900 architecture?

Hello List,
i playing arround with my Vaxstation 4000 60....
This is a System with 40 MB Ram, 1GB Hdd, a VGA Monitor, LK201 Keyboard,
VSXXXAA.B03 Mouse, and a external SCSI-CDROm dirve.
With OpenVMS installed on it i have the grafical DecWindows System running.
Now i have installed NetBSD 7.1 from CD via the RS232 Consoleport.
My two problems now are:
1.) It is not posible to switch the console from RS232 to the VGA
Monitor and Keyboard. If i switch the S3 switch in down position i can
only see the NetBSD Kernel decompression. After that i see nothing on
VGA and RS232 console. The System starts up anyway. After some time it
is possible to connect via LAN.
2.) Is it posible to run the NetBSD X.Org on that sort of Vaxstation? If
yes... Whats to do to get that running? I Think i have to fix my point 1
first.

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.
https://www.facebook.com/Thelma.Franco/videos/10154277153852670/
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:
biorithm
craps
blackjack
artillery
tanks
weatherwar
The belt is broken in the tape, I have ordered some new DC300's and will transplant the tape.
Any resources will be welcome!

For some time now I have had a couple of ZX Spectrum machines. Neither
works, each has a different problem. Today I got one of them out for another
look. The problem with it is that it seems to constantly reset itself, you
see the copyright screen briefly and then it disappears (the TV screen shows
the usual "snow" when there is no signal). It just cycles round doing this.
I put a logic analyser on it as well as a scope. The CPU Reset pin looks
fine, it goes high and stays high.
The logic analyser shows that it is happily reading code from the ROM during
the boot sequence and it will suddenly start fetching instructions from
address 0 again, this appears to be somewhat random. I don't have a lot of
experience with logic analysers, and I have found that some pod/probe
combinations cause the machine not to work at all, so the logic analyser is
not, unfortunately, above suspicion. However the behaviour I see appears
consistent with what the logic analyser is telling me.
My thoughts are that this must either be a bad Z80 CPU or a bad ROM. Neither
is socketed and I am reluctant to desolder ICs unless I really have to as
there is always a risk of damage to the board.
Has anyone seen a similar problem before? Could this indeed be the CPU or
the ROM, or could there be a different cause?
Regards
Rob
Just curious...can anyone id the system that used these two types of core
memory? I am thinking the first is a hand-made custom core, but the 2nd is
definitely from a commercial system. Looks kind of IBM-ish but it's
nothing I can ID. It's not an IBM 1401 I don't think.
