Roland and Korg both used an interface known as DIN Sync for synchronizing drum machines and sequencers. DIN Sync is named for the 5-pin DIN connector used; it’s the same connector used for MIDI, but DIN Sync is an entirely analogue interface and, of course, is not at all compatible with MIDI. DIN Sync provided a basic 24 or 48 pulse-per-quarter-note (ppqn) signal, as well as start/stop controls.
Roland’s DIN Sync machines used a 24ppqn clock, and include the TB-303 (input only), TR-606, TR-808, CR-8000, MC-202, and TR-909 (input only). Korg equipment such as the DDM-110, DDM-220, and KPR-77, however, used a 48ppqn clock. If you sync Korg and Roland together, the Korg will run at half speed
