I am interested in aquiring an 8087 math coprecessor for my Tandy 1000A. Do I have to buy a coprocessor made specifically for a Tandy (and consequently more expensive), or will any standard 8087 coprocessor work? Another possible problem might arise from a speed-up board installed in by computer (I don't remember the name, but it speeds the computer to 7.4 MHz; as of yet the only incompatability problem arises when I try to format disks. I have to switch to 4.77 MHz then. Every other program or function works fine.) Also, does anyone know of an inexpensive source for these (new or USED)? Thanks in advance!! Rusty jewett@mcnc.org

The 1000A has an 8087 socket. Since you are running a speed-up kit, you should get an 8087-2, which is rated up to 8 MHz. There may also be a jumper that you have to remove on your computer. (There was one on my SX.) The Intel literature that came with my chip had a mention that the 1000 socket was non-standard, and to talk to Radio Shack. It works fine in my SX with no problems. Maybe they were talking about the 1000, which had NO socket? andyross@ddsw1.MCS.COM
