   Those were the days.  We (Digex) used those DEC H960 racks too, with 
wooden shelves bolted in with angle brackets.  We used Lego blocks to 
space the modems apart to keep them
from overheating.

   When we finally got bigtime funding, we bought a bunch of those TCR 
boxes at nearly $30K apiece.  They were nice because their firmware was 
ComOS by Livingston, so all our existing stuff worked with them...our 
big banks of individual modems were connected to Livingston Portmaster 
PM2E-30 terminal servers which ran the "original" ComOS.

   Then when we started getting really big we bought Cisco AS5200s.  My 
GOD they were great.
