Hi, I bought a new USB/FW800/FW400 enclosure from a specialist Mac store. In system profiler it is listed as a "Impact TBS120 Rev B". I am a bit annoyed as I was expecting an Oxford 924 and this the same place that sold me a Macpower enclosure with a Prolific 3507 chipset a few years ago. It was rather expensive (about US$150) and won't mount on my PPC Powerbook's FW800, otherwise it seems to work mostly OK. Anybody know anything about this chipset? Should i return it?
