The 6800 is an 8-bit microprocessor produced by Motorola and released shortly after the Intel 8080 in late 1974. It had 78 instructions, including the (in)famous, undocumented Halt and Catch Fire (HCF) bus test instruction. It may have been the first microprocessor with an index register.
It was usually packaged in a 40 pin DIP (dual-inline package).

The 6800 is an 8-bit microprocessor produced by Motorola and released shortly after the Intel 8080 in late 1974. It had 78 instructions, including the (in)famous, undocumented Halt and Catch Fire (HCF) bus test instruction. It may have been the first microprocessor with an index register.
It was usually packaged in a 40 pin DIP (dual-inline package).
Several first-generation microcomputers of the 1970s, available by mail order as kits or in assembled form, used the 6800 as their CPU; examples are the MEK6800D2 development board, the SWTPC 6800 (the first computer to use the 6800), the MITS Altair 680 range (MITS offered these as alternatives to its Altair 8800 which used the Intel 8080), several of the Ohio Scientific designs, Gimix, Smoke Signal Broadcasting, Midwest Scientific, and the Newbear 77-68.
The 4051, a professional grade desktop graphical system intended for user programming in BASIC, was manufactured and sold by Tektronix. This integrated a 6800 processor, memory card,...
