Back in about 1985 I build a 6502 based controller.
But it used a 64 pin 6502 (about same size as a 6502 but the pins had different lengths, like some older LCD's )
And as I remember it also had build in RAM, and only needed a crystal to run.
Can any one tell me the name ?
I'm sseing if i can get a link
finally got an actual link
It was 1985!!
That chip had the option of Forth in rom.
Thanks
For some reason I wanted it to have 192 in the part number, but that was the RAM size.
Was it not made in 1985 since you make that comment?
I did not make the PCB but as I remember was the layout from a magazine probably Elector, and at the time it was a new chip.
ok it looks like it was a 6511Q, and from a photo I can see one made in (19)88 and that is probably correct for the time.
add:
there was also a 6511Q from (19)83 so 1985 was about correct I think
did you see

I don't understand your comment ...I exclaimed (you are correct): It was 1985!!
Maybe next time I will say: You won a million dollars!! & hope that is more exciting. After taxes are paid, it will feel like it is 1985.
Great Scott Marty, We have got to get you back to the future! (1985)
This is mostly because of the thread about writhing to eeprom all the time.
And this chip was the first I have seen with a special Vcc for a part of the RAM (32 bytes) that can be used as a raw kind of eeprom, but I was not sure anymore it's so long ago :)

Wasn't there an actual processor module that included a battery (like a Dallas Semi type "block" chip)? I know they had RTC's, but I'm thinking of on that included a microcontroller.
Yes but that was just a LP static RAM with a batt. on top .
