Hi.

Today I opend my DG AViiON 5500 to have a closer look at the chips
inside. I found:
XC88110RC40F (CPU)
XC88410RC50E (MMU)
NCR53C710 (SCSI)
AM79C900 (Ethernet)
Philips SCC2692 (dual UART, two pieces)
	SCN68562 (dual UART)
MK48T08 (RTC with CMOS RAM)
a big PGA module with two LSI L1A7980 and one unknown chip
LSI L1A7928
LSI L1B7465
DG ASCI, seems to be made by Fujitsu
MCM62110FN15-5 (8 pieces, seems to be cache RAM)
Xilinx FPGA/CPLD
second Ethernet on a card with a 79C900. The card has two 96 pin DIN
connectors and is about 15cm to 17cm in size. 

I also looked at the doc I have. Unfortunately I dont have any
dokumentation about the hardware internals.
