I believe the UMC made 6507 was used in the Atari 2600 Jr. console.
100% instruction compatible with the 6502. Made to access 8K of addressed memory. 28 Pins. 13 address lines.
8 bit accumulator.
I suppose most people do sprites in graphics programs nowadays. I am old school and still do them by hand.
This sheet has space for the bit map, the binary number representation and the $hex.
