How small could we conceivably make the VM to fit on one of these...?
For example the Mega...
MCU: 8-bit 16 MHz AVR
Current vm build product sizes...
That last one built without any internal nor external plugins.
What areas might be attacked to feasibly improve on that, to the point
it can meet rising hardware specs?
The 8 bit-ness is probably a killer though (??)
Maybe it would be better to port the VM to the ESP32...
MCU: 32-bit 240 Mhz Tensilica Xtensa LX6
ROM: 448 KBytes for booting and core functions
RAM: 520 KBytes
FLASH: 4MB (per retail boards - 4 x 16 MBytes supported)
Those specs look like they are getting close enough to consider possibility.
How small might an extremely minimal image be that just toggles an LED?
Hmmm.... I wonder where we might find someone both familiar with the
MCU and positively inclined to Smalltalk?
Some general ESP32 info...
