I bought a UBW32... Connected a few components and it powers up with an RGB monitor and runs excellent.... 8 colours, SD card as B drive, stereo sound and PS2 keyboard...
It works brilliantly I can get used to this device.... The only icky I have is the colours in MODE 4 ( Half resoultion ) are a bit messy... When I check the RGB output in the native mode, the signal is clean.. when in this half resolution MODE 4 the signal is noisy... Ill try to do a scope still frame and post it..... Meanwhile. Any Idea's
The only difference in the circuit ( apart from it being on stripboard ) is the diodes on the RGB output, the schematic has 1n4148 high speed diodes... I only had 1n914 high speed diodes.
I didn't think it was these as it works at the faster resolution..
