Lovely! Glad I wasn't part of the 1260 scam! :-)

Am I the only one who remembers 320MB/s Ultra-SCSI LVD? Granted I don't know the nuts and bolts but I don't believe that was serial and it is plenty fast enough even by today's standards with room to spare for the fastest hard drives we have shipping today...well, exclude that dual actuator MACH2 Seagate drive.

I mean plenty of ribbons used to bridge distance or allow flexibility of placement.

The longer the wires are parallel, the more pronounced the effect, and it can creep up enough to push a logical 0 above the lower logic threshold. And there be dragons (and crashes).

Shielding around cable a solution?

That way you won't be hobbled by the limitations of Zorro-II, and could use a dramatically more powerful graphics card than the Picasso II++. |
Hey, experts who know the details can ponder and look at a viable solution. Clearly there are a lot of 1200s in the wild, and if they can sell these people barely needed 1260s, I'm quite certain there would be at least 3x that many people buying a decent RTG solution for the 1200.
If there is anything I've learned, it's is not first, but best. And I'd put my money on iComp to deliver best 1240/1260 solutions soon with working prototypes shown - even if I won't be one buying it. Also iComp on delivering a 1200 RTG/FlickerFixer solution in the A1200 Reloaded, and probably soon after MK4 indivision that also delivers the RTG function. But at that point the RTG solution may be available for all maybe - 1200, 4000, even ECS/OCS machines maybe! Who knows. It would help him sell the P96 software - so there is extra motivation in it perhaps.
Seems he has all the pieces in place, and plenty of knowledge. AND replied to emails, allowed orders, processes them quickly, efficiently - imagine that!
