Subject: Fidelity Designer 2100 has a very primitive evaluation function

I purchased a Designer 2100 Display (6Mhz) from a friend of mine and decided to
test a couple of simple positions which ANY PC chess program should solve in a
matter of seconds.  In the first position the Fidelity computer couldn't find
the correct after over a half hour of thinking.  In the second position I let it
think for 20 minutes before turning it off never finding the right move.  Are
all dedicated units that weak?

These are taken from the "Mammouth Book of Chess."

1. d4 d5 2. Nf3 e6 3. c4 Nd7 4. Nc3 Ngf6 5. Bg5 Bb4 6. cxd5 exd5 7. Qa4 Bxc3+
8. bxc3 O-O 9. e3 c5 10. Bd3 c4 11. Bc2 Qe7 12. O-O a6 13. Rfe1 Qe6 14. Nd2 b5
15. Qa5 Ne4 16. Nxe4 dxe4 17. a4 Qd5 {18. axb5!)  This sacrifice is not
especially deep, but demonstrates in clear-cut fashion how the possibility of
creating a passed pawn must be borne in mind in the most innocent-looking
positions.}  *
