IBM P70

I found a rather interesting machine today at a local thrift store. It is an IBM PS/2 Model P70. Normally I don't pick up IBM PC's or clones, but this has the following: - luggable, roughly the size of a large breifcase - 80386 running at 20mhz - red gas-plasma VGA display - one 16-bit MCA and one 32-bit MCA expansion slot - 120meg IBM ESDI hard disk - 4meg RAM - parallel, serial, PS/2 mouse, VGA, and unknown HDI-30 connector on the rear. Unfortunately, it lacks it's keyboard, which isn't connected by way of the standard PS/2 connector. It won't boot past the memory test due to the lack of keyboard and it gives me POST error codes of 301, 162 and 163 on the screen, as well as beeps twice. Does anyone know what the square 30pin connector on the rear panel is? It reminds me of the HDI-30 SCSI connector found on some Powerbooks. I picked it up because I thought a portable Microchannel machine with a gas-plasma VGA screen was pretty interesting. Not to mention it's the only MCA machine I have.
