The Ampro EnCore was discussed on this list late last year. However, back
then the EnCore line was only the Pentium266 Encore 500. It looks like
they recently introduced three new configurations:

* low-power MIPS (2 watts -- max!)
* low-cost 486
* high-performance PIII(850MHz!)/Celeron

> Pros/Cons?
They all accept PC/104+ cards (PCI interface) -- could be very handy.

The high-performance model has onboard audio, a nice feature. Also, ultra
100 DMA EIDE, 10/100 ethernet, and 512MB SO-DIMM capability for its single
SO-DIMM slot.

It is (or was, anyway) more expensive than similar spec Advantec ware.
Ampro is typically not the low-cost leader, but has a solid reputation for
reliability. Here's a message from Doug posted last November (regarding
the EnCore500:

I think that Advantech is spoiling us and also is 
blowing the doors off almost all competition in 
terms of price for an all in one multimedia SBC. 
It might be hard to find another one as cheap. 
The $725 price for enCore 500 is not bad but ...

This is insanity.

Nonsense. I assume you won't be writing your own 
BIOS for the hardware, so you will never need 
the developers kit.

See if you can get a price on the DSP Design TP300. 
It's nice and small but has MediaGX audio/video.
This mated with a PC/104+ frame grabber would be 
4x4x1 inches, would have awesome video, and if we
can figure out how to load these NS CX5530 linux
drivers it would also have full duplex audio.

> Warnings?
The 850MHz PIII configuration should draw a substantial amount of power.
They haven't yet disclosed power-consumption figures in their PDF
brochures for any of the configurations except their MIPS version which,
as I said, draws 2 watts maximum (drool).

The PDF brochures say they are designed to interface to "a custom
baseboard" (carrier board) which I take to mean they don't offer
ready-made carrier boards. But I guess you don't need one since you can
apparently just use their $349 connector cable set -- *I guess*.

Advice:
Unless your expectations are *very* low, you should expect to have to
compromise. What are your expectations, BTW?

If you've been on the list for a little while, then you've probably
heard this: The archive is a good teacher.

The archive search engine is a bit slow so I just use normal, web-wide
search engines and narrow them down to wear-hard messages by including the
phrase *wear-hard* in quotes. For example, try searching for *encore* now
-- you'll get some hits from last ~November.
