What era? And, which market? The 6502 was a large commercial success
during it's era. It was the cheapest and most powerful chip of it's time.
The x86 is a large continuing commercial success in the PC market with
95-99%% market share per year. The ARM (and someone else had to update me on
this fairly recently...) is a very large commercial success in the embedded
market (cellphones, PDA's, etc.).

Well, WinBond says their ISDxxxx chips should be programmed in assembly or
C. So, FORTH is an implementors choice, but these 4-bit microcontrollers
don't run FORTH _natively_ anyway... They're not a FORTH microcontroller.

As for volume, you'll have to post links... I don't think your year and
half stint at Mattel eight years ago can provide relevant market data for
today. I don't doubt the musical card, or talking Barbies are decent
numbers. But, I know that while cards may be large numbers, very few cards
are musical cards today. Anyway, if there is public info on their volume, I
didn't find it...
