While I don't know of any GCOS 8 systems out there, Multics does include a GCOS batch simulator. Some customers of Multics used it (in preference to GCOS) because it was actually faster. While I can't vouch for the completeness or correctness of the GCOS batch system's working under the emulator, we know that at least some of it works, as the "map355" command needed to assemble the FNP image works under emulated Multics, and it uses the GCOS simulator to perform the assembly. There is also a GCOS TSS subsystem under Multics, but we have reason to believe that it isn't working quite right yet. There must be some difficult-to-find emulator bug that is causing issues when running commands under TSS. Feel free to check it out. -- Eric Message: 33 Date: Fri, 11 Mar 2016 20:51:28 -0800 From: Zane Healy <healyzh at aracnet.com> To: "General Discussion: On-Topic and Off-Topic Posts" <cctalk at classiccmp.org> Subject: Re: Any word on the Multics revival front?

That?s what I?d personally really like to boot on the emulator. I used to be able configure all the IOP?s, IOM?s, CPU?s, etc. from memory, power them up, and boot GCOS-8. Zane
