Atari Tempest (project)
|My main pcb (left pic.) and auxiliary circuit board (right pic.) of which the main board still has a fault. Despite changing the reset switch, 12Mhz crystal and various ic.s the only fault that remains is that the vector graphics are still screwy.|
|Left pic., the regulator pcb and spinner assembly. On the right the start of my build up of a substitute linear PSU using a torroidal transformer. (For the 36v AC)|
completed PSU, note the extra winding to supply the 10.6v DC (unreg.) |
On the right the PSU in action.......what a mess!
|Left, I've connected the X and Y outputs of the main pcb to my scope (set up for XY display). Note the image is back to front and the retrace lines are visible.|
