【Oki】ifNOTE40 series

The if NOTE 40 series was remarkable because it created the smallest letter-size (279 × 216 × 48 mm) 32-bit computers while fitting in a 20 MHz 80386SL processor — a 386 CPU for notebook computers — a 3.5-inch floppy drive, and a 40 MB hard drive. There were three models — the if 386 AX 41L, the if 386 AX 43L, and the if 386 AX 45L. At the time, there were demands on enterprise systems not only for more open and scaled-down systems but also for convergence of core information systems with office automation systems. The if NOTE 40 series was furnished with the client system features needed to achieve this system convergence. The 45L model was standard equipped with built-in Ethernet connectivity — the de facto LAN standard — and all models had the capability for built-in Ethernet. And in consideration of Windows’ memory requirements, the 43L and the 45L were standard equipped with 4 MB and were expandable up to 8 MB. OS/2 was also supported.
