Looking for a PM6100 for someone too :D
I did pull out my DOS card from my 6100 (didn't have DOS Compatible label somehow) because of the heat.
Unfortunately it only fitted in my Quadra 900/950 without case modding and it doesn't work properly I don't know why, these card are not the easiest...
And if you want to double check your install images, 6.0.8 is still available from Apple
1.4M version

It has been a while now but hey, time for an update.
And good one. Thanks to tecknight‘s video a was able to fix the PSU.
Mine shared the described problem, slowly becoming harder to power on until it died. Well it took only 4/5 attemps before it died, but this little guy had a rought life...
WOW. This is so unobtainium. Congrats on securing those precious finds!
Never stumbled on a MacTell copy before.
I may have a disk but someone (pc guy) repurposed as a dos disk for pirated stuff. Ugh.
Thank you I appreciate but I already bought one few months ago. :)
My restoration is still on hold but due to the PSU dying just after some tests, still working on this.
