The Diablo 1640 is a daisy-wheel printing terminal introduced in May, 1979.[1] The model 1640 uses a plastic print wheel and the model 1650 uses a metal print wheel. Both were available as a receive-only (RO) variant with no keyboard or a Keyboard Send-Receive (KSR) variant.
The 1640 is controlled by an Intel 8085 microprocessor. According to the Maintenance Manual, the logic is housed on a Microprocessor Controller Board. The firmware is stored in 12 KB of Read-Only Memory (ROM), while 2 KB of Random Access Memory (RAM) is provided for internal workspace and the print buffer.
The terminal features a print speed of 45 characters per second (cps). It supports high-resolution positioning with 1/120-inch horizontal and 1/48-inch vertical increments, enabling proportional spacing and plotting via software. The standard print buffer is 256 characters, which can be optionally expanded to 2,048 characters to accommodate sustained 1200 baud transmission.
