Pity the poor TTL computer aficionado. It’s an obsession, really — using discrete logic chips to scratch-build a computer that would probably compare unfavorably to an 80s era 8-bit machine in ...

[Tim] was able to perform this timing cycle with some simple ... for his 8-bit computer without violating any of his design principles and keeping everything to discrete TTL logic chips and ...

We've actually already seen one completely home-built 8-bit ... a simple 8-bit computer based on the SAP-1 architecture (SAP stands for Simple as Possible). The transistor-transistor logic ...
