HP-IL with HP 82163A Video Interface

[murphy9]

Whilst waiting for some level controllers to arrive from China, to follow the work that folks are doing with the RPI Pico I wondered how we control the displays (OLED or VGA/HMI etc) is the 'easiest' thing to 'virtualise' the HP-IL Video Interface within the Pico and then use the Pico to drive a display, such as an OLED (or in extreme a VGA/HDMI).

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.
