| Sold outChecked Jul 30, 2026 | Clockwork64by The Dark Forest | Adds a battery-backed DS3231 clock, external LED time display, date display, and timer to a Commodore 64. The Tindie page listed Clockwork64 at USD 38 but had ordering paused while the seller takes a break through July 31, 2026. It calls this the final batch before retirement, so confirm that an order can still be placed after the seller returns. A CR2032 is included. The maker reports compatibility problems with modern J-CIA replacement chips and directs buyers to version 0.2 of Timo Voutilainen's RTC software. |
