And yet, classic-3000 MPE (V/R, V/P, V/E) does not involve licensed third party stuff. At least I think it does not, I think the OS is uniquely developed by HP(E). MPE/iX does, I know I’ve been told that it includes a Streams implementation from Mentat which I understand was licensed on a per-copy royalty basis. That makes a zero-price license (even more of) a money-losing proposition. It also makes release of classic-3000 MPE dangerous in that people may assume that the release applies to MPE/iX as well, and that could leave HP liable for additional per-copy royalties in future. I think MPE/iX is not quite like OpenVMS in that there is no per-installation authorization key for the OS. The OS does check a machine ID in "stable storage" that is expected to indicate that the machine is an HP3000 (as opposed to an HP9000), and there are some other features that I believe indicate the class of HP3000 and I think MPE/iX and add-on software may check this for other purposes too. Which means that if the companies and people who are due per-copy royalties get the idea that they can goose that revenue stream through legal threats, HP(E) maybe can't provide a very good guesstimate of how many additional copies (for which royalties have not been paid) are out there. There might be some arguments made that the payment should be based on manufacturing counts of PA-RISC HP3000s and HP9000s. It could get expensive. Well, that's my guess of why then-HP didn't want to go there, and I don't think HPE today would think any differently. There may yet be a revenue stream from MPE/iX licenses as its paying users upgrade to newer hardware and the Stromasys emulator. > HP has no motivation to spend time/money to release this.

I just wish y'all had got FOCUS 9000 included in that. Earlier than 68K and maybe HP didn’t have the bits any more but I think some folks have some bits. May be AT&T-encumbered but no more so than the 68K 9000 bits. -Frank McConnell
