For anyone looking, I have all the files for the Personal Computer Power Series 830/850 (model 6050 / 6070 respectively). If you can’t find the SMS diskette or something else you need, contact me and i’ll make it available.
Remember, the machines boot Solaris, Windows NT, OS/2 Warp, AIX and Linux. That is, if you can get the PowerPC versions of said operating systems.
The above might work on the Personal Computer Power Series 440 (Model 6015), but since I’ve never had one in my possession I’ve never tried it.
