Re: ROMable SMSQ/E

So the Amiga "solves" the booting from 0 problem with reprogrammable vectors by having kickstart shadow at 0 and 10M on switch on, it then jumps to 10M and turns off the shadow at 0 leaving rom running high in memory map for initialisation of the vectors then OS.

It cant in any modern PC with Microsoft certification. The USB port is limited by hardware to 500mA.

(although old PCs there were about 20A or so available from USB port so equally cannot damage).

C68 4k Buffers on Stack SMSq/e

Are there any known issues with the combo in the topic?

So there was some friendly banter about Q68 beating SpeccyNext to your doorstep, well SpeccyNext was only a 170K$ project. This 500K GBP project is now years late and is likely to never deliver. https://www.theregister.co.uk/2017/12/13/retro_computers_ltd_internal_brouhaha/ So congrats to Peter and ...
