Written byMITS founder Ed Robertsand published just a few short months before the introduction of the Altair 8800, this historic book contains a wealth of information on early electronic calculators and desktop computers, with an emphasis on MITS' own product line (models 816, 908, 1200, and 1440, in particular). Covering everything fromcore and delay-line memoriesto the latest in large-scale integration, the book is loaded with dozens of schematics, as well as countless photos of vintage equipment - e.g.,Wang 452 & 700, HP 9810/9820, HP-35, and Friden 1152, among others - plus manybehind-the-scenes shots taken at MITS headquartersin Albuquerque, New Mexico. You get a rare glimpse into what the Altair's designers were up to right before the 8800 was released. Around 20 pages are devoted to theMITS Programmer(shown above), A 512-byte instruction sequencer with a hex keyboard and display that interfaces to a MITS 816 or 1440 calculator. With its conditional branch instruction and limited subroutine capability, the programmer/calculator combo could arguably be consideredMITS' first general-purpose personal computer.
