- Anyone know the story on this? Locally the price on USR Sporster 33.6K
- internal modems has dropped to $149 (Computer City), and when I installed
- one for a friend I found much to my great surprise that the Sportster now
- has a totally different chipset and datapump, and bears no relation to
- the older Sporster/Courier internals.
-
- The previous iternation of the Sporster had the same hardware and chipset
- as the Courier internals; the only difference was the contents of the
- firmware and whether a Flash ROM (Courier) or a regular PLCC ROM socket
- (Sportster) was installed. I'd previously compared these two circuit
- boards, the chipset and board itself were identical, with mask space for
- both the Courier's Flash ROM and for the Sporsters PLCC ROM socket on both.
-
- But now the "new" $149 Sporster 33.6K internals I've been seeing have a
- tiny little Texas Instruments chipset instead of the big NEC DSP, datapump,
- and Intel microcontroller.
-
- Unless this new TI chipset is a condensed-mask version of the old chipset
- (something I highly doubt, given the TI's dimunitive size and far, far
- fewer external leads than the previous Courier/Sportster's huge DSP), it
- seems to me we're basically looking at a totally different modem! The
- old reliability/performance/connectivity benchmarks would no longer apply
- to the new design, and it would have to be retested.
-
- Anyone seen any such tests on the new design? Anyone have the
- spec sheets for the tiny new integrated TI chipset that's now used on these
- newer, cheaper Sporster 33.6K's?
-
- Any comments and information are welcome.
