Unless it's a really old TP, there should be a PCMCIA card slot or two, possibly even a USB 1.1 port. I just got rid of a TP600 (Pentium II, max 288mb ram) that had both. I installed Win2K on it with a Linksys Wireless G PCMCIA card. Worked fine with decent speed on the 'net provided that the hard drive was kept fairly empty to handle the memory swap because of the low amount of system ram.
