TI's documented ALU slices (181, 481) have a bit in the opcode to invert either input. TI advertised the 960 with the slogan "bit pusher". 2 Quote Link to comment https://forums.atariage.com/topic/162941-assembly-on-the-994a/page/97/#findComment-5563594 Share on other sites More sharing options...
apersson850 Posted November 11 Share Posted November 11 We should also remember that the TMS 9900 didn't come about from a clean paper. It was the TI 990/9 implemented on a silicon chip. The decisions about which instructions to include was already taken by then, but for a TTL implementation. 4 Quote Link to comment https://forums.atariage.com/topic/162941-assembly-on-the-994a/page/97/#findComment-5563798 Share on other sites More sharing options...
