Thanks a million, Mike, for scanning and posting this.

I purchased this fix for my Altair way back when for $15, and it’s been one of those things that I’ve never been able to find online.  

I never purchased the Parasitic Engineering power supply fix, but I have found it online.  The Parasitic Engineering clock fix has eluded me until now.

BTW, IIRC, the PE clock fix worked excellently and I never had any clock related issues after installing it.  The S-100 bus, the weak power supply, not enough slots, all those wires on the bus, all gave me plenty of headaches, but the clock fix worked great!
