Which is on the face of it incorrect.
Then
There was a 4004 based computer developed in 1972 that was released before
the Micral called the Comstar 4. It's not very well known but it was
written about in the ACM and the Computer History Museum has a copy of
their sales manual

Could also have been a device from Oskar Heil in the 1930s.

The problem with this debate is that the definition of Personal Computer
is totally fluid and can be written so that the writers opinion is fact.
Each computer system has contributed, in some way, to those that followed.
If you really want say what is the first "personal" computing machine

Do your homewoork--the MCM-70 ran APL, had cassette storage and a
display and keyboard. The MITS 8800 had nothing other than RAM and a
CPU.
