what  about that intel 3000 bit slice  thing is  it almost  a microprocessor   yes  no  and   why?  Ed# In a message dated 11/21/2023 3:34:03 PM US Mountain Standard Time, c.murray.mccullough(a)gmail.com writes:  There are 5 other possibilities for the honour:e  or  noe  and why? No. 2:   Texas Instruments applied for a “computing systems CPU” in 1971 and awarded a patent in 1973. The question though is: did TI have a functioning processor based on the TMS1000. Not sure if they did! No. 3: “In 1969 Four-Phase Systems built the 24-bit AL1, which used multiple chips segmented into 8-bit hunks, not unlike a bit-slice processor. In a patent dispute a quarter century later proof was presented that one could implement a complete 8-bit microprocessor using just one of these chips. The battle was settled out of court, which did not settle the issue of the first micro.” No. 4:  Is this the first microprocessor?   Here is a source: https://historydraft.com/story/microprocessor/pico-electronics-and-general-… No. 5:   "In 1969 Four-Phase Systems built the 24-bit AL1, which used multiple chips segmented into 8-bit hunks, not unlike a bit-slice processor.

It seems the answer depends on what is a microprocessor...I suppose when it comes down to capitalism patents count more than anything else!
