A while ago I posted about my need for a PAUSE button for my 7800. a kind member Bryan took pity on me and shipped to me in Canada a PAUSE button
to end my madness at no cost for shipping/effort etc (THANKS SO MUCH BRYAN!) also just some mumblings on why I decided to keep my 7800 as I am in
a long process of going through my collection and trimming it down.
FWIW, the upcoming 7800XM module does not require an early 7800 with the expansion port. I mention this because, in the video, you seem to lament that you don't have that port when you allude to the 7800XM.
