they wanted to improve that from version to version but the original designer left MOS and founded his on company (ensoniq вЂ“ i think).ДЄnd the other designers had obviously not a clue how to fix that (with a few exceptions). The designer of that chip had no time to build a better analop opamp in it and this is the reason why the analog filters are different from chip to chip.

So the waveform generation was completely digital.

Well вЂ“ the SID had digital oszillators inside.

That cherished chip sits on a ZIF socket for the amazement of onlookers. The only thing not emulated is the SID chip. Everything in the original system is emulated, from the VIC, CIAs and VIAs, serial ports, and even the CPU of the 1541 disk drive. This is a direct emulation of the C64, down to individual opcodes in the 6510 CPU of the original. With the display, itвЂ™s effectively a C64 tablet, keyboard not included. Without the display, the entire project is just a bit bigger than a business card. ThereвЂ™s a display controller for a 7вЂі 800Г—480 TFT, and 4GB of memory for a library of C64 games. It uses the STM32F4, overclocked to 235 MHz.

On the project page, goes over the capabilities of his board. owes her success to her version, there are innumerableВ pieces of the C64 circuit floating around for various microcontrollers, and now has emulated everything (except the SID, thatвЂ™s still black magic) in a single ARM microcontroller. These engineers are all grown up now, and itвЂ™s about time for a few remakes. The Commodore 64 is the worlds bestselling computer, and weвЂ™re pretty sure most programmers and engineers above a certain age owe at least some of their career to this brown/beige keyboard thatвЂ™s also a computer.
