[vcf-midatlantic] IBM Series/1 emulator?

Hey all, I'm looking to see if there are any existing emulators known for the IBM Series/1 system. There are some disk images on Bitsavers (in addition to lots of docs, which is good), and I know a few members here have some experience with the system... anecdotally, it was said that there was some sort of emulation available for RS/6000, though that is extremely anecdotal and it's not even clear to me what platform it would be (AIX?). There doesn't seem to be a simh one that I've found. If anyone knows of any existing emulation solutions, I'd love to know about them. Thanks! - Dave
