Cromemco Bytesaver
The Bytesaver, introduced by Cromemco in 1976, was the first programmable memory board for the MITS Altair and S-100 bus microcomputer systems. The Bytesaver had sockets for 8 UV-erasable EPROMs providing up to 8 Kbytes of storage. The EPROMs could be programmed by the Bytesaver, or read as computer memory. In the history of microcomputer systems, the Bytesaver was the first viable alternative to the use of punched paper tape for storing programs, and has been called “a great advance in microcomputer technology”.
==Background==
The MITS Altair microcomputer, which began the personal computer revolution, was introduced in January 1975 with no hardware or software support for floppy disk or hard disk storage. When Paul Allen famously travelled to the MITS factory in Albuquerque, New Mexico to demonstrate what would become Microsoft Basic, he brought with him a punched paper tape of the code that he and Bill Gates had developed. According to Allen, the 7168 byte program took 7 minutes to load from an Teletype Model 33 paper tape reader.
To reduce the time required to load software, and to support a more convenient storage medium than paper tape, Cromemco developed the first programmable solid-state storage system for the Altair microcomputer. Cromemco called it the “Bytesaver” and introduced it in the February 1976 issue of Byte Magazine. With the Bytesaver the time to load Microsoft 8K Basic was reduced from 7 minutes to less than one second.
