Re: IBM PC Connecting to DECNET
Speaking of DEPCA, does anybody (a) know what kind of mouse connects (the docs just say DIGITAL MOUSE) and (b) know where to get one?

Re: A Personal Milestone (Data General Emulation)
Congratulations! Data General is one big gap in my experience and collection, great to know someone is working hard emulating the OS :) -Eric On Thu, Jun 2, 2022, 3:46 PM Stephen Merrony via cctech < cct...@classiccmp.org> wrote: > I hope hope you don't mind me sharing a little personal milestone: today > my long-winded attempt at a Data General AOS/VS emulator ran an original > third-party program successfully for the first time. > > There are actually two closely-coupled emulators, one that attempts to > emulate MV class hardware, and another that tries to provide a virtual > AOS/VS environment. > > Due to the frustrating lack of freely available documentation and > software for these machines which ceased production in the mid-1990s, I > am now focusing on the AOS/VS emulator. > > Oh, the program that ran was OTHELLO, from the NADGUG (North American > Data General User Group) games collection.

Re: A Personal Milestone (Data General Emulation)
Very cool. Maybe this will cause some of the documentation and software that have been locked away in various private archives to finally shake loose!

I found the DEPCA card I needed, the correct scripts now run, etc. I tore down my VAX cluster some time ago, I would need to set up a new one, change the scripts to match the services available and the names to continue with this project.

A Personal Milestone (Data General Emulation)
I hope hope you don't mind me sharing a little personal milestone: today my long-winded attempt at a Data General AOS/VS emulator ran an original third-party program successfully for the first time. There are actually two closely-coupled emulators, one that attempts to emulate MV class hardware, and another that tries to provide a virtual AOS/VS environment. Due to the frustrating lack of freely available documentation and software for these machines which ceased production in the mid-1990s, I am now focusing on the AOS/VS emulator. Oh, the program that ran was OTHELLO, from the NADGUG (North American Data General User Group) games collection. I lost the game :-/ If anyone is interested, the emulator status is here: https://github.com/SMerrony/dgemua/blob/main/STATUS.md Steve
Your pictures of a Tullamore pulse height analyzer on flickr
Hello Patrick, I came across your pictures of a Tullamore pulse heigh analyzer on flickr while looking for more information about these systems on internet. Did you possibly take more pictures of this unit which are not on flickr? If so, then I'd be interested in these as more pictures can help me to fix my unit which has two missing front panels. Thanks in advance for any feedback! With kind regards, Pierre - http://www.digitalheritage.de
