Morrow - SuperRAM
This was an early Morrow S-100 board
when the name of the company was Tinker Toys.
ECONORAM was one of the first low cost fully buffered S-100 memory boards on
the market. It was actually designed by George Morrow. It made its
appearance in the hobbyist community as the 2102 1K memory chip made its way
down the learning curve into high production. Next was the 2114, a 4K chip. This
board by Morrow provided a low cost, fully buffered 16K static memory board
based on the 2114 at a price almost equivalent to the early 4K based boards.
The DIP switches at the top of the board
allowed fine resolution board addressing. There was a write protect memory
option -- though seldom used. One wait state could be added and was required for
a 4MHz Z80.
