I am currently programming via the "sample electronics programmer" via LPT1. My new laptop only has a couple of USB ports... what are my options?

Thanks in advance.

you can use stk500 programmer that use usb port
or use avr isp programmer and then use usb to rs232 for it

Hi,

Try that:

I am not sure is going to work.
Timing could be critical with your LPT programmer.

Development on a PC without a serial port it's almost
impossible. You will need a serial port while debugging or
when your program inside the AVR uses the serial port to
communicate with a PC.

The Atmel STK500 uses the serial port. (Not USB).

Best regards,

Would a pcmcia legacy parallel card work? It adds a couple of parallel ports which can be set for lpt1,2 or 3. What ya'll think?

Yes.
