- There's really nothing that's impossible. Given enough money and
- time, it is certainly "possible" to upgrade an E to an E+. It's also
- "possible" to upgrade a 286/10 to a 486DX2/66 without getting a new
- motherboard.
-
- The question isn't whether it's possible or impossible. The question
- really is whether it's PRACTICAL. Just as it isn't practical to
- upgrade your 286 to a 486 without getting a new motherboard, my
- feeling is that it isn't practical to upgrade your E to an E+. Sure,
- you could pull out your 'scope and your soldering iron and, with
- several hours' work, replace the appropriate parts in an E to turn it
- into an E+. But most of us consider our time somewhat valuable. In
- the time it would take you to make the modification, you could
- probably go out and earn the difference between the cost of a DIY
- upgrade and the cost of a new E+. Assuming, of course, you are the
- sort of person with the requisite skills to actually perform the DIY
- upgrade.
-
- What's more, if you buy an E+, you can then sell your E to someone
- else and recover part of the cost of the upgrade. And you end up with
- a new modem that still has the 5-year warranty. If you perform the
- DIY upgrade, you will definitely void your warranty.
-
- This is pretty much the same reason that ZyXEL/Zero One doesn't offer
- an upgrade. The "upgrade" would probably consist of taking out your E
- board and putting in an E+ board. If you're going to replace the
- whole innards of the modem, you might as well replace the shell and
- the power supply and end up with an entire new modem, instead of
- something as useless as a bare E board.

-
- Except from what Tyrone and others have said, the differences aren't
- confined to just the piggyback DSP memory card. A faster 68000 is
- used (although I'm not too pleased with the fact that they're running
- a 16MHz 68000 at 20MHz...), as well as a faster DSP. This is *not* a
- trivial, swap-a-few-socketed-chips upgrade, kids.
