It's based on CPLD chip, not FPGA. Then will support TXT mode in next screen
layer with possibility use transparent color. Theoretically can CPU make
sprites/graphic from separate characters (graphic blocks 8x8 pixels, smaller or
bigger...) Background can be standard SAM screen in mode 3 or 4. Now I must
finish first beta version of CPLD firmware for testing and in next step add
more features/expansions.

In an ideal world you could have :
32/8 full colour hardware sprites ...16x16 or 8x8 ? with sprite collision
detection ?
Hardware scroll vertical/horizontal
Increase in Colour palette
Hardware line interrupts (programmable) to switch palette at a fixed number
of scan lines ? No need for CPU intervention.
Even a second Video processor to give superposition, Superimposed video. This
could be something like a V9938/V9958. though this obviously would mean quite a
bit of extra circuitry, but the resulting graphics would be superb, probably
surpassing a Commodore AMIGA.
Though this all boils down to someone with the time, brains and means to make
it happen !

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?

I agree. 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.

No hardware scroll, no sprites. But text mode with transparent color(s).
Theoretically may palete contain up to 65536 colors.

Velesoft, you say, the SAM2 will have 256 colours at once. Does this
mean, the colour palette is enhanced to 512 or even 4096 colours?
Will it have hardware scrolling or hardware sprites too?

Text modes will usable in color modes 16c/pixel and in hi-res mode(also
color
pixels). Yes, font will in ram.
New graphic mode will 256x192/256 colors each pixel and may be also
512x192/256c.

Yes. All membranes will usable. 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. Membrane is under software controll thanks to second
CPU Z80.
All software for second CPU will be in assembler Z80 and rewritable
direct from
computer :-)
