I recently completed an emulator for the G-15. It supports the basic machine configuration
-- just paper tape and typewriter I/O -- but I'm interested in implementing other
peripheral devices as software that uses them becomes available. The emulator attempts to
run at the speed of a real G-15, which is pretty slow. It successfully passes the one
diagnostic test I have.
The emulator is web-based and should run in reasonably recent versions of any of the
popular web browsers. I've tested it with Firefox, Google Chrome, Apple Safari, and
Microsoft Edge. You can run the emulator directly from my hosting site at
https://www.phkimpel.us/Bendix-G15/ or you can download the files from GitHub and run it
from some other web server. Once the emulator loads into the browser, there's no
further interaction with the server.
From the link above there are additional links to the GitHub repo, the wiki, and
additional resources. Issues concerning the emulator can be posted on the GitHub repo.
I don't currently have much software for the emulator, but am working with Rob Kolstad
to curate a large stash that recently became available. What software I do have is
available on a separate GitHub repo at
https://github.com/retro-software/G15-software/.
Additional contributions are welcome.
