Or do we use some microcode calls to create the functions to paint pixels on a screen?

All "above my paygrade" at the moment, but I thought this older thread might inspire some ideas around the ultiimate goal of giving the 41c a proper graphics capability. Perhaps the commands on the 48 or Prime is a possiblity for the graphing commands.

The obvious question is why not just use a Prime instead - well it's the same answer as why not an iphone. "Because" - because we like to push this 40 year plus device beyond anything it's original architects thought possible.

Can de achieved straight
a) Use a PI2 and install according https://www.hpmuseum.org/forum/thread-19053.html
b) Connect an HDMI to the PI2 (in the thread above the whole system is installed in the PI2 but as long no HDMI is connected, you will not see it)
.. Done
- you will see the ILVIDEO80 screen of https://hp.giesselink.com/hpil.htm
- the system is a PILBOX + PI2..or3/4 + Screen via HDMI (or not if only access to the virtual drive is the target)
- nothing to screw, solder,.. just a calibration of a quite standard system PI2/3/3 (look at eBay or others) + PILBOX ( JF Garnier ) + HP71B or HP41

Update: since I have interest to review/check the whole installation procedure again, if you want to have a virtual and/or a Video80 at the HDMI of a PI,
- send me a PI2..3..4 (in an housing; thats easier)
- A SD card for boot 16G
- an USB for Virtual drive storage
I can make the install (or 2..) and send back the stuff.
