Some quotes worth mentioning:

Quote:
WM: Did you know that the 816 is probably the largest selling 16-bit microprocessor of all time?

RW: Not...



Quote:
There are more then 40 companies that are under license right now to build my microprocessor. You probably didn't know that. Rockwell, Hyundai, NCR part of AT and T before Hyundai built them, but I licensed Hyundai individually, Seiko, Rico, Rico builds the chip sets for Nintendo, ITT in Germany, the Swatch organization, these kind of companies. So what my plan is is to have a low cost, low power system like this for communicating words. So while the world is looking at the Pentium and the Pentium Pro, I'm looking at the other end.

The real question is, what is the 6502 line doing today? Nothing else matters right now.

However, I have made very few edits to the 6502 and 65C02 articles. My edits to the 65C816 article were to clarify the relationship of the 65C816 to the rest of the 6502 family, correct minor errors and to expand the historical information a bit. That information came directly from Bill Mensch via E-mail.

The one 6502-related article that I originated and to which I did extensive edits was "interrupts in 65xx processors."

The 65C02 is shipping at the rate of hundreds of millions per year, although largely invisible to most people. A member of my large scale model railroad club had an implanted heart defibrillator before he received a transplant. The defib, which he still has in a little box at home, is powered by a 65C02 core.

And perhaps we can agree that WDC's 65C02 is the surviving 6502 variant - I wouldn't go so far as to call it definitive, as it was neither the first 6502 variant or the first CMOS variant. History may be written by the winners, but we needn't give all the glory to Bill. He's built a successful business but was not the prime mover.

Mensch designed the 65C02, so that would make his creation definitive for the CMOS line.

Just came across this, which supports your statement and contradicts mine:
Quote:
Working alone and without outside funding, Mensch designed the 65C02, adding a few new instructions while he created the low-power CMOS design. The chip has a different microarchitecture than the original 6502, using PLA-based microcode for instruction sequencing.

After completing the design, he went back to the same companies, offering to license it to them. This time, both GTE and Rockwell accepted, and Commodore promptly sued for theft of trade secrets. In another out-of-court settlement, Commodore settled in return for being granted the rights to the 65C02 for internal use at half the standard license fee. Synertek also licensed WDC’s 65C02.

Jack Tramiel was one of the pioneers of using lawsuits instead of technical innovation to crush his competitors. Looking back on it, it's highly likely that Commodore's baseless lawsuit was settled as it was because WDC could not afford the cost of taking it to trial. Commodore, of course, never used the 65C02 or a derivative in any released product, and Tramiel was fired by Irving Gould within a year after the suit was settled.

I never heard that about the lawsuits except for Jack suing over the buyback of pre-Amiga material. I read almost all of the computer magazines back then for news and it wasn't public knowledge and the magazines were pro-Commodore. The only other lawsuit I know if is MOS being sued by Motorola over the 6501 being pin compatible with something else.

Jack produced computers from two different computer companies and gave everyone big competition. Had Jack stayed at Commodore, maybe Commodore could have enjoyed some of that success but they were competing against all of these 6502 computers because MOS sold it to everyone. Irving Gould is probably a name that I wish I never heard because Commodore went bankrupt and you know the rest of that story; Irving Gould didn't make another computer.

Had I known that Amiga would have went bankrupt, I would have bought 6502 kits and Eprom burners back then and I would have bought an IBM compatible instead.

WDC and Apple are the only ones that stayed in business because they were the only real computer people and everyone else didn't stay in business because they didn't compete at the chip level by pouring billions of dollars into chip research by making them faster. The Wall Street Journal kept predicting Commodore's bankruptcy.

The lawsuit against WDC was pretty quiet and the only reason I knew anything about it was because my employer had designed a locomotive event recorder around the 6502, which was in the late 1970s. A second design effort was started around 1982, if I correctly recall, using the 65C02 (for technical reasons that I won't go into in this post). That project was pushed to the back burner when the lawsuit was mentioned in the technical press at the time. I suspect management didn't want to expend engineering time on a product for which a microprocessor could not be obtained.

The Commodore 64, which came into being in 1982, and was produced into the early 1990s, was a runaway best-seller, despite the competition from other 65xx-powered machines. Tramiel was ousted in January 1984, which was before C-64 sales reached their apex.

It should be noted that while CSG chips were theoretically available to any computer manufacturer who wanted them, the internal transfer cost between CSG and the rest of Commodore was well below the price that other manufacturers could get. Hence they started at a disadvantage, which had more than a little to do with the C-64's success.

More blame for Commodore's failure should be heaped upon Mehdi Ali than Gould, as it was the former who supposedly knew the computer business. Gould was a financier.

By the late 1980s, many were predicting the Amiga's demise at the hand of the x86 architecture. Part of the blame rested with Commodore for poorly marketing the Amiga, and some blame belonged to Motorola for poorly promoting the 68K architecture, which was technically superior to Intel's offerings at the time. In the world of computers, technical excellence seldom is the source of success. If it were, today we'd all be running Linux on Macs with PowerPC MPUs and SCSI subsystems.

Apple spent comparatively little money on chip design. WDC, being a chip design company, naturally spent money to develop a product, but it was nowhere near billions—Bill Mensch didn't have that kind of working capital. Mensch was shrewd in reworking an already proven design (NMOS 6502) to correct errata and extend the instruction set without a major capital outlay. He exhibited good business sense in promoting the 65C02 to Apple, and in having the foresight to realize that intellectual property would have long-term value, whereas chip foundries would come and go. I may get some argument on this, but I'm reasonably certain that WDC was the first fabless semiconductor house.

As did many other pundits of the time. The day that Tramiel left Commodore was the day the long, slow slide started.
