I0908@DKAFHS1.BITNET (05/14/89)
Date: 13 May 1989, 20:20:53 SET From: Cornelius Caesar BITNET / EARN: I0908 at DKAFHS1 To: info-atari16 at score.stanford.edu I just found another (german) ST magazine which I did't know before. (If someone is interested: ST VISION Postfach 1651 D-6070 Langen West Germany full coverage of the Atari ST) The May/June issue has a small article about using the HD 6301 keyboard processor as an (integer) co-processor for the 68000. For this they poke a little program into the 6301's 128 byte RAM which apparently has to interprete later to be given parameters. A sample BASIC loader does this by resetting the 6301 and poking in that program, which reads a command plus two arguments. The result can then be read out from the keyboard processor. Of course that is only a demo, but the author claims that some programs can be made faster up to 15 % with clever programming. Can somebody comment this? Are there dangerous drawbacks? Cornelius
