All — I’m looking for a working M8186/KDF-11 dual-height CPU card, mostly as an experiment to see if it would work in place of the LSI-11 (11/03) card in my Heath H-11 for the purposes of getting BSD 2.11 working. Not sure if that’s even possible, so maybe let’s start with that. Will BSD run on a KDF-11 (11/23) if I have sufficient RAM? Thanks!

No, you need split I&D for 2.11BSD, which means J11 in the QBus world. You'd want to try with the KDJ11-A, which is a dual height card. You will almost certainly need to add bits to the address bus on the backplane.

That’s an 11/73 right? With the “Jaws” CPU.

You could run 2.9BSD on a KDF11. I've done it on an 11/24. -ethan On Wed, Aug 1, 2018, 09:54 Richard Cini via vcf-midatlantic < vcf-midatlantic@lists.vcfed.org> wrote:

Seconded. 2.9BSD works fine on F11 chipsets; my 11/23 handles it just fine. If you're in search of one, I might have one spare. Let me know if you're still looking and I'll poke around in my stash (which needs reorganization anyway). If in doubt, try out your intended system in SimH first. It'll usually give you an OK idea whether it'll work. - Dave
