RCB1586 identifies a Micro/sys board associated with the documented SBC1586 Pentium PC/104 computer platform. The platform provides embedded x86 processing, SDRAM, onboard flash, CompactFlash storage, serial communications, USB, and PC/104 expansion. Processor speed, Ethernet, temperature grade, installed memory, and software options require the full SBC1586 order code or unit label; RCB1586 alone does not establish those configured details
Configurations vary. Verify the exact unit before choosing a replacement.

CompactFlash is not hot-swappable.
The software-enabled watchdog must be refreshed every 1.6 seconds to prevent a board reset.
The extended-temperature upper operating limit depends on forced airflow.
