I guess I should add, ‘cruiser’ was nowhere near to the point of running anything on NT/OS2 was it?

The OS/2 subsystem in NT was needed for more than just SQL. I mean, the whole reason Workgroup Applications (hi!) released client and server software for OS/2 was because Australia Telecom was the biggest Microsoft Mail install in the world at 50,000 seats, ran _mostly_ OS/2 1.31, and bought premium-tier support, so when they said “jump” we said “how high?”

I don’t know if that was as important as SQL but it was pretty important. They stood pat for a _long_ time on OS/2 1/31 and Microsoft Mail 3.0-3.5 and being there for them in 16-bit OS/2 was a big deal to keeping them from defecting to… who even knows what, right?

I don’t know if that was as important as SQL but it was pretty important.

There is some ‘free’ portable SOM, somFree.

Some code that I would really want to see would be SOM (System Object Model) and Workplace Shell. I believe we don’t have nothing today like SOM, we could load libraries and call method/functions, but no Object Orientation at the Operating System Level.
I read that RPC have security problems hard to fix and that was why it was not used anymore, but I don’t remember if SOM or DSOM (Distributed System Object Model) used RPC.

Thank you for sharing.
So much software and documentation has been lost for older programs, especially non games.
I think I don’t have much software that isn’t at the net and the last time I tried to read some of my diskettes, some of them had bad sectors, but I will try again. Unfortunately I don’t live in a first world country and because my situation I don’t have a Kryoflux, but will try again to read the diskettes and see what I have stored all this years.
Again, thank you for sharing 🙂

from what I remember the JFS code that made it’s way to Linux came from OS/2 PowerPC.

HPFS is a Microsoft thing, and well if you look at ‘European DOS’ aka the ‘link4’ Windows 1/2 magic it’s all Microsoft.

I remember a few years ago, I don’t remember how many… There was a movement to make IBM release the OS/2 source code, (probably Warp or other version from IBM). A spokesperson from IBM said that IBM was in favor of releasing the code, but… that part of the code was licensed from other companies and would be complicated to get the permission from these companies to release the code and I think that was the end of it.

Yep, pretty much. and it’s guaranteed to be useless in this day & age as it’s no doubt 100% hand tuned 80286 assembly. If anything the ‘useful’ bit would be fixing all the timing issues, and maybe making the errors more useful other than the infamous ‘error in country.sys’ nonsense.
