notes: label: Description
content: John Henderson (1944-2017), a computer scientist by training, founded Tall Tree systems in Palo Alto, California in 1974 and ran it until 1992. One of the primary products of the company was JRAM memory boards that allowed users to expand the memory of IBM PC microcomputers and their clones. This is the manual for a sucessful product of the company known as the JRAM-2X, a circuit board with installed random access memory. Also included are two copies of a letter from the donor, Michael L. Sher, in which he returns his JRAM-2 board with clock and calendar module, populated with 1,280K RAM, to exchange it for a similarly configured JRAM-3 board with the requisite software, operating manuals, and instructions. Sher planned to install the board in an IBM Portable PC. Included with these documents is an advertisement for JRAM-3 from an unlisted source.
