Using 64GB cards now, so thats a never mind, and if its the clone of the 
kernel srcs, it does not exist on the card, but on an attached 240GB 
ssd.

My biggest problem is that no matter  how many times I build a fully 
pre-emptible kernel 4.19.y-rt using the raspbian git clone of their 
whole kernel tree, then branch 4.19.y-rt, it will not boot on a pi3b.  
Always hangs halfway thru the boot. And there is not a realtime branch 
of 4.14.y in the raspi kernel git clone.  It will set that branch, but 
theres no realtime there.

Then after 4 passes at that 4.19.y-rt install, cleaning out media etc I 
don't need, then it can't find its own / filesystem by its PARTUUID, so 
I obviously deleted something it needs.  So, while the pi3 has the iron 
to run the machine just fine, I am stuck with 1.7 fps video. And I have 
overwritten that jessie install sd card. So ATM the machine is DIW.

So, I going to take that same build recipe, assemble an interface and 
7i90HD card with some blown by noise output gates, and see if I can 
build a fully pre-emptible sd for a pi4.

Which means I'll have to solder some power leads to the cable adapter 
because I don't have an otg power plug, and I have heard the otg 
pluggin, used as a power feed, doesn't work that well anyway, so it will 
need power on its header, which its running fine with right now and has 
been since the day after I got it.

Either that, or I shitcan all the pi stuff (by-by $400+ and over 2 years 
time) and see if I can find a good D-525MW board on ebay and install our 
last stretch based iso.  But I'll have to study what Peter has that 
might let me salvage some of the drivers as I'll need at least 3 
encoders and a boatload of i/o.

Has anyone here used a 7i90HD (with 7i42TA's of coarse) in parport mode 
direct from a D525MW's parport? Is it fast enough to run the  machinery?

Exploring possibilities here.

Cheers, Gene Heskett
