Sorry, but these pictures are not quite clear. There's probably some
TAB to space conversion or text formatting done which made the drawings
a mess...
I tried to view them with several fonts and sizes in my mail prgram,
but I got no picture which made sense :-(
Could it be that they're supposed to look like this:
,---------+---------- composite
| | ___
| ___ `-| \
composite -+-| \ |AND )O-- HSync
|AND )O---|___/
Vsync -+-|___/
|
`-------------------- Vsync
(So: composite direct out and to NAND1/In1 and NAND2/In1
Vsync direct out and to NAND1/In2
NAND1/OUT to NAND2/In2
NAND2/OUT to HSync)
and
Comp
(CBE) BC549 VGA
+5 ------'|`---------+-- Hsync
| |
HSync -[100]-' ,-[560]-'
|
GND ----------+---------- GND
VSync --------------------- Vsync
(So: Comp +5 to BC549/C,
Comp HSync to BC549/B via 100R
Comp GND to VGA GND and Hsync VGA via 560R
Comp Vsync to VGA VSync
B549/E to VGAHSync)
(Now hope, that *my* mailer doesn't fuck up the pictures ;-))
BTW I thought that the refresh rates used by the MSX were too
low to use on current (S)VGA monitors...
