they were not "veryuch in the home pc market" they released the ps/1 to "reenter" the home market. the ps/2 was older. and never had a 486dx 2. th ps/1 had one 486dc2. so yes its possible but tjis article is about ibm losing the home market and they lost it by then, since the ps/1 was them trying one last time to "reeneter" it.
