SCC bug is now fixed and the antialiasing filter was redesigned also. The output volume levels for SSG and SSC were readjusted.
TOSLINK/SPDIF output is now fully operational.
New DEMO was recorded to provide an early experience.

Procyon now emulates SCC, SSG, PPI MSX audio hardware. Also it includes the 16 bit audio DMA, which is used at the start-up for the SDRAM and AC97 CODEC test purposes.
And here is the VIDEO of the audio demo.
Short video below demonstrates Procyon capability to successfully emulate the MSX-1 Video processor (TMS9918) functionality and provide the memory expansion. Sprites are not yet supported.
One of Procyon boards was assembled.
Power, clock distribution, FPGA configuration and HDMI connectivity subsystems are functional. The burn-in test is yet to be done.
Procyon Arcade MSX compatible FPGA platform PCBs were manufactured in Sunnyvale and currently transported by FEDEX.
