802.11b was the first widespread wifi standard and it was not even released 11 years ago (October '99), and yet you had a computer with similar specifications ? I assume you refer to a laptop using 'wavelan' ?
The closest that I can remember from those days to what is offered here was the compaq contura aero, after that the Toshiba libretto, neither of them had built in wifi (heck, they had no networking at all, just a serial port, and a pcmcia slot that you could plug an ethernet expansion card in if you felt like spending more $ on that than on the whole laptop discussed in this thread).
Both of these machines were of a build quality that the machine you're looking at here probably could not match, but their price points were considerably higher.
What make & model was it ?
