A 1024 channel multichannel analyzer has been built using eight-bit S-100 bus microcomputer hardware. The analyzer has pulse height analysis and multiscaling data acquisition modes. A Mossbauer control signal is provided. The output modes are an oscilloscope display, print data, and send data to another computer. The system's hardware and software are described. Costs and advantages relative to commercial multichannels are discussed. © 1979, American Association of Physics Teachers. All rights reserved.
