[Kenwood] M54730 Proms for Kenwood

[James True N5ARW]

Help!!!

I have collected several Kenwood commercial FM radios that I would like to put on the ham bands.  They are models TK-601S, TK-701S, ant TK-801S.  I am having a problem finding the PROMs to reprogram them with.  I have a prom burner at work to actually do the programming if I could just find the chips.  What I need are M54730AP 32 x 8bit PROM chips.  Each radio takes two so I could use a bunch if I can find them.  I don't normally work with digital circuits and can't find any reference material on these chips.

Does anyone know where I can get the PROMs or if there are any other parts that this might cross to.  I have been searching the web with google but have not had any success.  Any advise, leads, assistance appreciated.

Thanks & 73
