2001 PC/ADSM broadband modem compatible?

[noorjabal]

I have been offered a free second-hand PC that was purchased new by an office in 2001 (to have as a spare as I work from home). I currently use an ADSM mobile broadband USB modem (Sony Ericsson MD3000) as my area has a landline infrastructure shortage. Am I likely to get OK internet access with this modem on the free computer re. 2001 hardware/software technology? As I don't have a car I'd like to know before I arrange transort if the free computer + modem are likely to work together, or if the computer might need expensive alterations before use. Any clues or tips would be very greatly appreciated.

Should be fine hardware wise...
However Drivers are the important thing.
What OS is on the 2nd hand PC ? ?
Does it have USB ports ? ?
Or does the modem have an RJ45 jack it can use ? ?

Many thanks, Patio! I'll ask the owner for the information. Re. the jack, I usually plug the modem straight into the USB. It does have a short accompanying cable that can link modem and computer cable, which I occasionally use to change the position of the modem for signal-improvement. The package just calls this a "USB Extension Cable". Not sure is this is the jack you mention.
