That doesn't contain memory provided in the revision number though. Is this data that you are looking for? Are you working on making a gpio parport? If you are, are you intending to make it work with the 7i76 and its cousins sserial expansions? That would be kewl if its fast enough to pull that off. I didn't find that even a 1 gig pi3 has problems building linuxcnc after I'd made a 10 gig swap on a 120gb ssd and added it to /etc/fstab. Building linuxcnc on the pi3 ran it around 85 megs into swap, and when that ssd was moved to the pi4 with 2 gigs, it used about 50 megs to build the rs274 interpreter. But the faster usb-3 interface on the pi4 sped up the build considerably. Well under an hour.
