Interesting :-) I own several ceramic ones of those. But I'm not planning to use them in the near future, instead my next project will be to create my own ALU using solely with 7400 NAND chips.
- VLM 10y agoYou can also go the opposite direction although its much slower by burning 4K eprom (12 bits is 4 bits of A, 4 bits of B, and 4 bits of opcode, 12 bits is a 4K eprom). Both modern eeprom or eprom or especially old eprom will be much slower than the old TTL implementations by maybe a factor of ten. The interest in this design is modern eproms can be quite large, of course the largest ones are serial which is quite useless for this purpose, but 8 bit ALUs are possible.
- XtalJ 10y agoIt is an interesting approach to build a simple ALU or similar that is worth giving a thought. However, using only NAND gates is more of a fun thing to do :-)
