Oreo,
The latest software version available for the Show Designer-1 is version 3.08 and yes, it does have the Focus Spot-250 in the fixture library.
Regarding the serial lap link cable- traditionally, it has a 9 & 25 pin sub connectors on both sides. However, you do not use the 25 pin connectors. You insert one 9 pin connector into the RS232 port of your Show Designer and the other 9 pin connector into COM 1 port of your PC. If your computer doesn't have a 9 pin sub connector, you will also have to buy a USB to RS-232 converter cable which consists of one 9 pin male sub connector to USB.
FYI - We also make a Show Designer disk drive unit that you'd use in place of your computer. Click this link to read more about it.
