==Storia==

Processor Technology fu fondata da [[Bob Marsh]], un membro dell'[[Homebrew Computer Club]], e [[Gary Ingram]] nel mese di aprile del [[1975]] per commercializzare delle [[scheda elettronica|schede]] di [[memoria (informatica)|memoria]] per l'[[MITS Altair 8800|Altair 8800]] dato che le schede fornite da [[Micro Instrumentation and Telemetry Systems|MITS]] non erano affidabili.<ref name="old">{{cita web|url=http://www.old-computers.com/museum/computer.asp?st=1&c=344|titolo=Processor Technology Sol-20|editore=Old-computers.com|accesso=22/03/2011}}</ref><ref name="sol">{{cita web|url=http://www.pc-history.org/sol.htm|titolo=Storia del computer Sol|editore=PC-History.org|accesso=22/03/2011}}</ref>

Bob Marsh, [[Lee Felsenstein]] and [[Gordon French]] started designing the [[Sol-20]] between April and July of 1975. The Sol-20 utilized the [[Intel 8080]] 8-bit [[microprocessor]] chip, running at 2 MHz. A major difference between the Sol-20 and most other machines of the era was its built-in video driver, which allowed it to be attached to a [[composite monitor]] for display. The Sol-20 consisted of a main [[Printed circuit board|motherboard]] (PCB) mounted at the bottom of the case, and a five slot [[S-100 bus]] card cage. The main PCB consisted of the CPU, memory, video display, I/O circuits. Inside the case included power supply, fan, and keyboard. The sides of case are solid oiled [[walnut]] wood, and blue painted steel.

Processor Technology manufactured approximately 10,000 Sol-20 personal computers between 1977 and 1979. All Processor Technology products were available either fully assembled, or as [[electronic kits]]. Processor Technology also sold software on [[Cassette tape]]. One side of the tape was recorded in CUTS format, and the other side was [[Kansas City standard]] format. Gary Ingram and Steven Dompier wrote the original software utilities. [[Lee Felsenstein]] wrote the original user manuals as a contractor.
