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. m

Dec-10 Day announcement from Living Computers: Museum + Labs

by RichA＠livingcomputers.org

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/MDE2 https://github.com/livingcomputermuseum/MBS https://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!

Vaxstation 3100 of odd sort on epay

by jwsmail＠jwsss.com

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. VINTAGE-RARE-DEC-DIGITAL-VAXSTATION-3100-PF-VS42A-AA-RF-VS42A-BN-COMPUTER-SYSTEM/ http://www.ebay.com/itm/370930391341 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. thanks Jim

EPROM baking

by Mark＠Misty.com

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. Mark -- Mark G. Thomas (Mark at Misty.com), KC3DRE

To the 2901 bit slicers out there

by rdawson16＠hotmail.com

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? http://www.donnamaie.com/AMD_Vintage/AMD_2900_ED2900A.html Donnamaie E.

Vaxstation 4000 m60 and NetBSD

by marco＠familie-rauhut.eu

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. Marco Rauhut

Tek 40xx computer users

by rdawson16＠hotmail.com

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! Randy

ZX Spectrum Z80 Keeps Resetting

by robert.jarratt＠ntlworld.com

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

ID some core memory

by billdegnan＠gmail.com

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. http://vintagecomputer.net/core-memory/ Thanks Bill
