This unit
The Densan DVE-68K/42 is a VMEbus-compatible CPU board built around the Motorola MC68040 processor, delivering 66 MHz core performance in a double-height, single-slot form factor. This industrial-grade board integrates 16 MB of DRAM, 8 MB of fixed flash memory, dual ROM sockets, and a Compact Flash Type 1 interface, making it suitable for embedded systems requiring reliable compute and storage in compact installations. The board features dual 24-bit timers, two DMA controllers, a watchdog timer, and battery-backed RTC with 512 KB SRAM. Network connectivity is provided via 10BASE-T Ethernet; four-channel serial I/O via ST16C2550 controller supports legacy industrial communications. VMEbus master/slave operation across A32/A24/A16 address spaces and D32/D16/D08 data widths enables flexible system integration.
