The problem pretty much solved yesterday (Thursday) on Erik's VCF. My
guess is that it simply takes that long for some messages to post.
Part in question is the 74S288 bipolar PROM and used in the
write-precomp portion of the 820 FDC board. Fortunately, the OP managed
to find the reference design for the WD179x.
I posted on the VCF the web site for a guy who will program 288s for a
very reasonable charge.
