Hi,
I'm posting here a few images about the technical self tests of the game. Most of them definitely need some tweaking according to the manual, but I really don't have any idea to understand what needs to be done. Can someone please help?
CROSSHATCH PATTERN DISPLAY
GRID PATTERN DISPLAY
the manual says, in both cases, to "refer to the linearity adjustement procedure in the Analog Vector-Generator Schematic diagrams"--- can anyone please where do I find this info and how can I make these displays look as they should?
BIPOLAR OFFSET TEST DISPLAY
the manual says that there should be just one box, which is obvioulsy not what it looks like... they say "adjust X/Y bipolar offset potentiometerslocated in the digital to analog converterand bipolar current sources circuit on the analog vector generator PCB.
RASTER SCREEN DISPLAY
This one is a mystery: it's fairly different from what it should be according to manual, but it just says that it's used by the manufacturer to adjust the white tracking of the display circuitry... in the pic the colour looks white, but it's actually red.
The looks of the game in-play is not bad - as far as I remember it looks pretty good and vectors seem fine. I have a problem with the yoke controller, which is not responding, but that's another story...
I don't know which monitor is mounted on my game, what I noticed cleaning the screen, is that the cathode tube displays some remnants of the TEMPEST (vertical) videogame. Tehre is no brand anywhere on the monitor and behind it, I am really unable to determine which one is it...
Thanks to all
