While working at the scrapyard today, i managed to get a couple 386 machines right as they were being dropped off. One is a pakard bell with monitor, in pristine condition. The other is a Tandy 2500 with monitor, in rough looking shape but working too. The monitor is pretty beat up for the tandy but working. I have been on the look ut for a good 386 mahine for a while now, i got kinda lucky and picked up two working systems in one day. The pakard bell is up and running fine, it was a pretty standard machine and just needed a hard drive. The tandy 2500 is pretty nice as well, it has a cdrom and a hard drive installed, although the hard drive is dead and seems to only accept AT hard drives. I am still learning about tandy computers, on my other machines, i was unable to find an 8 bit isa cad that could support newer ide drives. On the machine i just picked up it looks like a 16 bit isa slot is free, if i were to install a 16 bit ide hard drive controller for use with newer ide drives, would it work, or cause some kind of conflict with the onboard hard drive controller? The floppy drive is quite dirty but reads disks sometimes, i need to clean it up. Im hoping to post back with a couple pictures of both the machines running. I do not need them both, I really like the packard bell, but if someone absolutely needs a 386 machine with monitor I am open to offers to get one shipped out and keep the other one. --Devin

Anyone have the service guide for a Sanyo VM4209 monitor?

by janso96＠hotmail.com

Hi, I'm trying to repair this monitor, but unfortunately I can't find any service manual or guide with schematics for it. I found something on www.electronic-circuitry.com<http://www.electronic-circuitry.com>, but it's impossible to download. Thanks in advance, Janek Sochaczewski

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! Rich Richard Alderson, Sr. Systems Engineer Living Computers: Museum + Labs 2245 1st Avenue S Seattle, WA 98134 Cell: (206) 465-2916 Desk: (206) 342-2239 http://www.livingcomputerss.org/

AlphaCom Terminal

by billdegnan＠gmail.com

The 1969-71 AlphaCom terminal is a candidate for https://terminals-wiki.org/ Here are some photos http://www.vintagecomputer.net/browse_thread.cfm?id=502 I got this from the inventor's son. I am unsure how many of these were made or put into production. The terminal kind-of worked for a while, it saves forms in core memory and transmits them like a glass teletype (i.e. datapoint 3300) and would have been a competitor machine. Unfortunately it's too complex for me to decipher, there are no schematics and I am unable to get it running again. The Sanyo TV adapted as a display is also dysfunctional now. Perhaps someone here would like to help me make progress. I have a ton of photos on my site, linked from the above thread, but doubtless more research is necessary. I am located in Landenberg, PA USA near Philadelphia due west of Newark Delaware. BIll

DEC compatible boards

by useddec＠gmail.com

I have well over 100, maybe 200 DEC compatible boards which I have no plans to use. Maybe 20 or so EMULEX, DILOG, ADAC, DATA TRANSLATIONS, and dozens or other manufacturers. Also the ones that have no company name on them. They range from a few PDP-8 boards, to Q-bus. Unibus, to VAX. I hope to have a complete list sometime later this year, bur feel free to send a wish list (off list)and I will dig through them. Thanks, Paul

It is just the manuals. Seth answered me and I am pretty sure he is going to take them. I don't have the 200 pound hardware anymore.
