I think hardware sprites would be great, increase in colour palette would be beneficial as long as more colours on screen at once was introduced but given the size of the screen as standard is 24k more colours on screen would mean more memory unless line interrupts were used then this would have speed issues on the cpu, so how could this be used?

The original (crowdfunding) plans for the "new" Golden ASIC's involved hardware sprites and palette expansion to 4096, which is enough for most needs, and this as upgrade for the original SAM 1.

Does this mean, the colour palette is enhanced to 512 or even 4096 colours? Will it have hardware scrolling or hardware sprites too?

ZX membrane, +2A/+3 membrane, laptom keyboards, sam coupe membrane, membrane from any PS/2 or USB keyboards... Keyboard module use software autodetection on all pins of connected membrane. If you connect any new membrane, must be call software test which test membrane state during pressing key by key. After detect all states save new configuration for your keyboard.
