The PM-i387(V) is a combination of an all-in-one CPU card, V-disk card and VGA card. It is based on the 386SX compatible CPU and will run 80386DX, 80486DX and Pentium software. The PM-i387(V) offers high speed performance at a moderate cost.

The PM-i387(V) is a half-sized card that run at 40MHz and can have up to 32MB of DRAM. The card has an on-board Watch-Dog timer, a Buzzer, and a battery-backed Real Time Clock. It comes with AMI BIOS which is mapped to the upper 64K of memory. PM-i387(V) also provides a Floppy disk controller, an IDE disk controller, two serial ports, and one parallel port.

The PM-i387(V) is equipped with 1.7MB Flash disk and three 32-pin DIP IC sockets. These sockets can accommodate 1Mbit (128KB), 2Mbit (256KB), 4MBit (512KB) and 8Mbit (1024KB) SRAM, EPROM and Flash EPROMs. This allows the PM-i387(V) to feature up to 4.7MB Virtual disk drive. The PM-i387(V) SRAM/Flash EPROM V-disk can also be programmed over a RS-232/RS-422 communication I/F from another computer, this gives the flexibility and convenience of programming or re-programming a PM-i387(V) with Flash EPROMs or SRAMs in a diskless computer.

The IBM PC-DOS 6.3 can be bundled with PM-i387(V). There are 2 versions available. The standard PC-DOS includes all PC-DOS files .The ROM version PC-DOS includes only system boot files - IBMBIO.COM, IBMDOS.COM, COMMAND.COM and FORMAT.COM.

The PM-i387V has VGA on board, the VGA supports both CRT and LCD panel and has up to 1024x768 resolution in CRT display mode and 800x600 in LCD display mode.
