Hi, I have the Data sheet you are looking for. It's in the General Instrument Microelectronics Product Catalog dated 1980. I could scan the data. It is a Keyboard Encoder and Prom/Eprom Application. It is the same as the AY-5-3600 except that the output is binary coded so that it can address an external prom/eprom which then outputs the required character(what ever you want). Let me Know Bye for now Eric Naus At 11:50 AM 9/30/97 +0800, you wrote: >-----Г©l¦l´—----- >±H´—»í: Mark [SMTP:mbolding@uab.edu] >¦‚¡e¨ƒ¦Á: 1997Ï~9Û‘13ÛŽ AM 02:01 >Ï´—»í: PICLIST@MITVMA.MIT.EDU >´DϨ: ask for help.
