ok , you got me confused here, the 8565 does not have a storage pcb since it uses a storage CRT , as far as connecting a digitizer that should be fairly easy, as far as i remember the 8565 has a interface connector to connect a storage normalizer (8750) on the back panel, this connector gives you acess to all the signals you need for this task.
However if you put in the time and effort to go for digital storage why dont you ponder the idea of discarding the CRT at all and replace it with a LCD panel, there is a bunch of embedded controllers that offer LCD/TFT interface build in, all you need is a microcontroller, A/D converter and a Surplus TFT panel and youre ready to go

Hi fellow hp'ers,
I'm the new owner of a HP8565 SA and think its pretty good. However,
the hacker in me is already pondering modding it. In particular, I have
been thinking of replacing the storage pcb with a new one, only
operating the tube in conventional mode and using the rest of the space
to add a digitiser/playback system. Has anyone else attempted something
similar? Although digital systems and ADCs are now fast enough to do
this - I chose the 8565 because it YIG RF systems still seem current
state of art - and I could always digitise the rear outputs with
something to avoid having to use the long persistence. I was prompted
to write this after reading John Mills email about trying to increase
the stability of his 8566 YIG and stated thinking maybe the 8565 could
benefit from this? ( by the way - great web site you have!)
The 8565 was at the price I could afford, I would have gone for an 8569
and would LOVE an 8566 - but here in Australia they're expensive - even
through ebay - the shipping cost kills any bargains!
But this is a hobby and I like hacking and modding.
Another thought was to route the if signal to a DSO and FFT for greater
resolution - would the 8565 LO be stable enough?
Thanks for any thoughts
