Questions on today's acquisitions

Made a few purchases today, and have questions on them all: HP 150 with an HP 9133 expansion chassis. Anybody know what kind of keyboard this takes? It has a 6 prong telephone style connector. Texas Instruments Compact Computer 40. This is a lot like the TRS-80 PC-4 in appearance, but a bit bigger. It has BASIC in ROM and a connector for cartridges. Is there anything actually useful for this? THe keyboards too small to do any actual word processing. MPP-1150 Parallel Printer Interface by Supra Corporation. This has a parallel connector on the one end and a strange 13 pin connector which looks something like this: _______ |_______| /_______\ on the other end. Does anybody know what computer this goes to? And lastly, I have a single IC in a bag labeled "printer". The chip says "NEC RI8739-I35 D2332C 374". Does anybody know what this is? Anybody want it?
