On the C64 SID chip, ring accentuation multiplies a triangle beachcomber with a aboveboard wave.
On an ARP Odyssey synthesizer (and a few others from that era as well) the ring modulator is an XOR action (formed from two NAND gates) fed from the aboveboard beachcomber outputs of the two oscillators. For the bound case of aboveboard or beating beachcomber signals, this is identical to accurate ring modulation.
Analog multiplier ICs (such as those fabricated by Analog Devices) would plan absolutely accurately as ring modulators, of advance with attention to such affairs as their operating banned and calibration factors. Use of multplier ICs agency that the accentuation articles are abundantly bedfast to sum and aberration abundance of inputs (unless the ambit is overdriven), rather than the abundant added complicated articles of the rectifier circuit.
