How many transistors are there approximately in the C64 if we consider every chip on it? I think that it is something around 50.000 but I'm not sure.
- 6510: ~3500
- VIC II: ? (est. 5000)
- 2x CIA: ? (est. 2000)
- PLA: ? (est. 1000)
- SID: ? (est. 2000)
- commodity chips: ~500?
- 64K DRAM: ~526000 (one transistor per bit, one transistor per row per bus width)
- 512 B SRAM: ~25000 (six transistors per bit
- 20K ROM: ~160000 (one transistor or diode per bit)
The bulk number goes to the RAM, 50,000 isn't nearly enough though. I've tried to (very roughly) estimate the unknown ones - I'm definitely no expert - leading to some 100,000.
edit: very embarrassing - I counted bytes as bits...So, we've got around 14,000 for logic and some 710,000 for memory.
