C64 LCD display

Just a quick Sunday hack:

The LCD display has probably got a much more powerful cpu in it, than the Commodore C64 has got.
JOKE 
(Although it might have, actually. Maybe 4 bits, but possibly a higher frequency capable and/or MIPs per clock-cycle/MHz version, than the 6502, I'm not sure).

Well, minimum enable cycle time is 1.2 us, so might be as good as a 6502

Not nearly as much potential vintage fun though.

Arguably, the 6502, is one of the main, influential Microprocessors, which has started off this massive computer revolution, which is still occurring. With the 8080/Z80, (possibly the 8051) and especially the 8088/8086, as well as others.
Also arguably the Amazon Echo (and google and other variants, such as Apple's Siri). May also be looked back to in 20, 50 or 100 years time, and be blamed for being the start of a new AI revolution.

The 6502 was probably the first truly affordable (cheap) and generally/freely available cpu, which helped spark off a massive computer revolution. But the others had major roles to play as well.

Apparently the Arm (which is one of the biggest by sales volume cpus), originally comes from the 6502, rather indirectly though. Through the BBC micro (6502), and that teams attempts at making a new processor for the future BBC micro computers. Hence the start of Arm (both company and cpu chips).

Character LCDs don't have CPUs, they just have controller chips. I doubt they run at more than a couple of hundred KHz.

My comments were really meant as a light hearted joke. Not a serious technical claim about modern day LCD controllers.

If there was a modern 4 bit microcontroller in it. It would probably do something like 10+ MHz, and so it probably would be faster. But would run at a much lower frequency to save power, when driving the LCD.

Dedicated non-MCU LCD controllers make a lot of sense.
