This is not anything the shack ever sold.  This one runs on a set of extra 
chips piggybacked into the deluxe rs-232 pack.  Either a M$ or a Logitech 
serial mouse works as the driver switches modes on 1st receipt of a mouse 
packet that can only come from the M$ mouse.  They are quite similar with 
the difference being in how the 3rd button is handled.

The driver I wrote is joydrv_6551L.sb in the nitros9 tree for level 2 
stuffs.  No jumps, no spasticity like the shacks mice, just works.  For me, 
but my piggybacked chips might not be at the same I/O address as yours, I 
have a very faint, 20+ yo memory of having moved it for some reason.  The 
driver cab be patched with ded in that event to fix that sort of thing.
 
Cheers, Gene
