1. Can it be that this very SuperMac card only accepts a 3x BNC SuperMac monitor? If so, I can supply homebrew cable details, I think. My SuperMac card, a Spectrum 8 series II from 1988, only wants 3x BNC. I don't know the use sense pinnings off-hand. 2. If you refer to the Monitor CP that came with your OS, that might very well be - and remain - the case. There should be a second Monitor CP, devoted to that 17" Multithing. After setting that one, and if the Multiscan software behaves nicely, the graphics card and its monitor ought to show up in the normal Monitor CP. This may reguire a few restarts. 3. Does the Mac send these dissapointing signals to the on-board connector or to the graphics card? 4. The card does not recognize the extended sense line codes. For a 17" Multiscan monitor (max res 1024 x 768 + as many colours as the card can handle), the sense pinning should be code 11: one diode from line1 (pin7) to line2 (pin10) and line0 (pin 4) grounded. You can fool the Mac into thinking there's an older 19" fixed freq monitor attached by feeding it code 58: a plain wire connection between line0 (pin 4) and line2 (pin7) This requires the cutting of a cable, some nifty multimetering and some soldering. Even then, I can't guarantee that it works here. good luck -mart -- Vintage Macs is sponsored by <http://lowendmac.com/> and...
