I worked there back in the early '80s. Aside from publishing Tunnels and Trolls and the Nuclear War card game, we did play-by-mail computer-moderated games.
Our main computer was a Raytheon with magnetic core memory and punched-tape I/O. Those were the days. It was pretty cool in that when the Arizona summer monsoons came in, we'd just flip the power switch and turn it off. Storm passes: turn it back on and resume production. If the machine got wonky, there was a certain cross-beam in the memory cage that you'd strategically place a 2x4 and whap the end of it with a hammer for a couple of minutes to randomize the memory, then reload the OS and you were back to work. I never got to see this happen.
Fun times. But anyway....
The head programmer, Steve MacGregor, was an absolute nut for Pascal. Anything that was an in-house game that didn't run on Theo, the Raytheon, he wrote in Pascal on CP/M boxes. And since it was all UCSD p-code, it was easy to port to new computers as they came in over the years, long after I was gone. While I was learning programming at the time, sadly I wasn't into Pascal just then and didn't appreciate it. I wish I had been, I could've learned a lot from Steve as he was quite the wizard.
Even more sadly, Flying Buffalo is no more, Rick Loomis the founder passed away in 2019. The Tunnels and Trolls and other properties have been bought up and are still available on DriveThruRPG, and it appears the play-by-(e)mail games are still going, who knows how long that'll be up.
