Well David it appears it's time for you to start dumpstre diving. I picked (or out
depending how you look at it) three old laptops 1 286 1 386 and 1 486 all of which
had several 245's in the oh so convenient surface mount sizing. I just grabbed on
off the floor to double check and after 30 seconds I counted 5 245's 5 244's
remember the device is not really a motor driver it is an octal buffer thus any
computer that is currently manufactured or was manufactured has to have at least 1!
