Hi Gunther,
I posted on the freebsd-small list a couple of months ago about doing a small
x86 embedded communication engine for running FreeBSd (or OpenBSD or Linux....)
I have looked at the MachZ too, but has decided against using it, and I will
instead use two alternative chips.
The first board I'm doing use the the AMD SC520, that cost about half as much,
and are only missing the IDE and USB controller and some of the multi I/O
functions. But you don't need any of that in a small communication engine....
The next board I will do will probably use the new National Semiconductor
SC3200, which has everything the MachZ has PLUS more, runs at up to 266 Mhz AND
still cost less....
And btw, the first board is getting VERY close to being ready, I'm finishing up
the PCB layout right now, and expect to have working prototype in about two
weeks. The final specs are:
100/133 Mhz AMD SC520.
16-64 Mbyte SDRAM, soldered on board.
1 Mbit BIOS/BOOT Flash.
CompactFLASH socket, 8 Mbyte to ??.
2-3 10/100 mbit Ethernet ports, RJ-45.
1 Serial port, DB9. (Optional 3 serial ports)
Power LED, Activity LED.
MiniPCI type III socket. (For optional hardware encryption.)
PCI Slot, right angle 3.3V only. (For optional WAN board.)
8 bit general purpurse I/O, 14 pins header.
Size 4.8" x 5.5".
Power either 5V DC fixed or 7-20V DC, max 8W.
I plan to make two versions avaliable as standard products, a minimal version
with a small box and using a wall transformer, and a full version using a box
with internal power supply that can be rack mounted.
I don't have any pricing yet, but do have a target of below $200 for the small
version in single units.
Regards,
Soren
