Mainboards & Motherboards
System boards and motherboards for IBM SurePOS and Toshiba POS terminals
48 products
Replacement main boards and SBCs (single-board computers) for major POS terminal families — IBM 4690-series, Toshiba 4900/SurePOS 700, NCR 7610/7700, Wincor BEETLE and HP rp5800. We carry both new-old-stock OEM boards and tested-refurbished pulls, each with the original FCC/CE labels intact and the CMOS battery freshly replaced. Board-level repair on these legacy terminals usually beats whole-unit replacement on cost: a single mainboard swap can return a $2,000-list terminal to service for under $400. Each listing includes the OEM part number, FRU number where applicable, supported OS list and any known errata.

Frequently asked questions
Can I swap a 4900-785 board into a 4900-545 chassis?
Generally no — Toshiba changed the I/O backplane between sub-models. Within the same numerical model (e.g. 4900-785 to another 4900-785), boards are interchangeable. Across sub-models, check the OEM part number against the FRU listing; physical fitment may match but a mismatch in the I/O cage typically results in non-functional integrated USB, serial or cash-drawer kick lines.
Why is the CMOS battery important?
POS mainboards store the BIOS configuration — CPU settings, boot device order, integrated peripheral enables — in CMOS NVRAM backed by a CR2032 coin cell. When the battery dies, the board reverts to defaults at every power-on, which can disable critical peripherals or the boot device. Every board we ship has a freshly tested battery installed, so the unit boots correctly out of the box.
How do I tell if my failing terminal is the mainboard or the PSU?
Symptoms point the way. Random reboots under load and intermittent USB dropouts usually indicate PSU failure (electrolytic capacitors aging out). Failure to POST, beep-code errors, or complete dead-on-arrival are mainboard-side. A PSU is much cheaper to swap as a diagnostic step — if a known-good PSU doesn't restore the unit, replace the board.
What about OS licensing on a replacement board?
Most legacy POS terminals use OEM Windows or POSReady licensing tied to the hardware. A new board will require re-activation or a new license. For 4690 OS, IBM/Toshiba's licensing was perpetual but tied to the serial — speak to your licensing channel before swapping. Our team can advise on common scenarios at request-quote time.
