Ok, got my Quest in last night and took a look at the board and chip. It WILL NOT
work with DM3/4/5 chips.
Will all markers work basically the same, but the external interface on the Quest is different then a DM3/4/5. The DM markers have 2
buttons on the back to operate it, and have 4
DIPs inside. The Quest has 1
button on the back to operate it and 2
DIPs inside. Just that alone means the logic you have to code the chip to work with won't work. Maybe hte chips themself may work, but chips programmed for DM3/4/5 markers will not.
But hey, that just means someone has to make an aftermarker chip now for them!
Hey FEP, who makes you boards and codes your chips now? If you don't mind telling us.
