Join Daniel Renner as he reviews the latest SID replacement chip called the ARMSID by Nobomi with a C64 Reloaded board.
Some information about the ARMSID:
- A new replacement of the MOS6581 and MOS8580 used in the Commodore C64.
- Real “plug & play” solution. Just insert instead of the original SID into the slot and it’s done.
- No need to switch the PAL / NTSC version, the circuit uses directly the clock from the computer bus, always synchronous with the C64.
- It determines (through supply voltages) which chip it replaces and starts the appropriate emulation (it can be changed later in software).
- It also emulates analog inputs (joysticks, mouse, etc. – POTX and POTY inputs)
- Analog output is sufficiently buffered, it is not necessary to change anything on the computer board for proper operation.
- Output sampling frequency is 1/16th bus clock of C64 (approx. 62kHz), real 12bit D/A converter, no pwm.
- Filters completely transferred to digital form, emulated by float point arithmetic.
- Significantly lower noise level and less interference from the power supply than the original.
- Lower power consumption than the original.
- Firmware update possible inside the C64.
