I've been interested in SymbOS for a number of years now, since the first time someone (no, not our member 'Someone') first brought it to my attention.
The first hurdle would be lack of a timer in the older models, but this could quickly be overcome by using an interrupt generated by VSync linked to a PIO pin
like what has been done on the PC85 for a psuedo RTC.
It would be good to implement it on the Premium Plus & 256TC-SE as they have 1Mbyte ram.
Monochrome 640 x 256 resolution would be o.k. (I don't think SymbOS would lend itself to Colour per Character well).
Not saying too much about it at this stage, BUT, the Classic Plus (yes it is being worked on) will be much more suitable graphics wise.
Looking over the SymbOS website though, it appears not to be open source, nor are there any contact links to try and encourage a port along.
