Franklin Ace 2200 --> CGA video jumper settings fixed

["DeaconBlue" <locksmith64@doramail.com>]

Hello!

It seems the solution was to un-jumper W2 on  the videobard from the 
recommended CGA-mode postion

Recommended setting:  IBM CGA-signal:  W2, W4 and W8 (jumpered)

leaving only:   W4, W8  as jumpered.

I do not have a manual describing the the jumper-options, but  probably the 
W2 controls the vertical-sync polarity in TTL-mode.

The image produced by the Franklin looks sharp and defined on the CBM 1084S 
monitor.  The odd-color characters sometimes shown when using the Video7 
Enhancer on the Apple IIc seems no be present on this setup.

best regards
