easy way for fix this bug. ( Replace pull-up resistors on SAM COUPE... it's
not tested, but can help )

by desoldering a Atari Mega
STE), I lost BRIGHT too as the ASIC was toasted a little too. After replacing
it with ASIC from my spare SAM the BRIGHT is back again.
It is time to design a replacement ASIC. Velesoft is working on one since
years, but he is too ambitious: 4096 Colours, Hardware
development is very fast (some days/one week), and next time will used for
fixing bugs...

Yes. Now I plan all modes fast/uncontended. Perfect memory contention timing

in games. Laptop
keyboard is small, cheap and is possible buy each type more years after release.
SAM 2 use universal adapter for connect any laptop keyboard and will use define
keys after first connect new keyboard (any membrane). Each user can define own
keys layout.

No idea about price. Yet is all in development. Board without case will cheaper.

definitely prefer a standard PC keyboard

easily implementable type) instead of the current design.

Do you have a rough time estimate when we might see it. Six months, a year,
longer
. Now I must
finish first beta version of CPLD firmware for testing and in next step add
more features/expansions.

Here is my version of DATA-GEAR (Z80 DMA interface for SAM COUPE). It's
internal version for connection instead original Z80CPU (need replace
CPU with socket).

VIDEO (sorry, bad quality and low FPS). Almost fullscreen scroll 25 fps

for possibility disable MIDI ports

Now run DMA stable only with fast block transfer (disconnect CPU and
stransfer data). I will test soon also byte mode = DMA transfer only one
byte and return to CPU. I must make counter which set speed of DMA
transfer.
Yes, is possible also make external DMA interface
VELESOFT

11904 bytes per one frame 50Hz is maximum speed in mode 4 with active
screen. With external 1MB memory can be dma transfer faster. DMA scroll
can move screen data from external ram to internal ram. Access to
external ram is always fast(uncontended).
