Just curious to see what you guys think it's worth. I'm gonna be selling these soon.
It's AutoTap version 1 hardware so it's fairly old. Just has the GM generic parameters. Still works fine though. I used it for years on all my GM cars including to log and tune my f-body and my buddies vette. Also used it on my vortec truck to trouble shoot a misfire a couple of years ago. Although it's old it's still a good diagnostic tool. The new stuff is $199 and can read CAN protocol.

I also have an older HP laptop. 360mhz pentium 2 and 128 ram with a cd rom ( not sure of the speed, I'll have to check) and a floppy drive. No modem. Serial port and usb port.
