BYTE Magazines available

I have the following issues of BYTE Magazine available: 1976: 3-12 1977: 2-12 1978: 1-12 1979: 1-2,4-7,9-12 1980: 1-7,9-12 1981: 1-7,9-12 1982: 1-7,9-12 1983: 1-12 1984: 1-12 1985: 1-2,5-11 1986: 1-12 1987: 1-4,6-12 1988: 1,3-10,12 1989: 1-9 1991: 2-9 In addition, I have a number of special issues like the IBM special issues. I have no idea what if anything these are worth. Mostly, I'm just trying to avoid throwing them in the trash. Of course, I'd love to trade them for interesting stuff. What would I like? I'm mostly interested in a working SBC6120 system (front panel not necessary). Another thing I've been looking for is a copy of the Bliss-32 reference manual. I used Bliss when I worked for DEC and liked some aspects of it but haven't been able to find a manual. They are located in southern New Hampshire.
