If redundancy due to PC board is expected in 5 years - don't market it so high!
I still think there is some misunderstandings about what I am trying to say...
PC board = "Printed Circuit Board" - that's fine and ALL machines are doing well with good quality here
PC = "Personal Computer" - the thing on your home/office desk - this is what Heighway and JJP are basing their machine on for the controlling system and THIS is not on IMO.
It is the Personal Computer part that will cause problems and I'm afraid it makes NO DIFFERENCE what you pay for a motherboard - they are ALL only made to last a few years -
THIS is what the problem is - Stern is sticking with embedded controllers NOT PC's and they have proven to be reliable over 30 years.
Turn your computer on and wait 5 mins for it to boot - same with your JJP and Heighway - it just isn't going to cut it
