"Troika sure didn`t start to design the board to underbid the MicroA1 price but to deliver an OS4 compatible board at all, as there was doubt for a long time if we would ever see something from Eytech again."
Sorry.. I just have to ask...
1) Does this thing really exisits.. There's been numerous boards announced (and having photos of them) during last decade and essentially *none* of them ever made to production so IMHO it's valid quesiton to ask how come this woudl be one of the Few making it.
2) *HOW* can you be sure this board will be compatible (and able) to run OS4??? IIRC There's been no official (nor inofficial) confirmation of them getting 'the license' or board been tested by Hyperion coders.
