Slow Train Coming

Not much progress on the DRM-RX yet, besides me looking into the gate design of TTL and LS-TTL NANDs and NOTs. BTW, both are almost identical. I wonder if it would be better to use open-collector gates when using the logic-circuits in analog mode... Browsing the internet, I only found standard TTL gates used. But most designs, other than oscillators, are making essentially use of the logic functions. Hmmmm, looks like I will have to hack things into SPICE, before continue thought on matters.

As Bob sings, "there's a slow train coming".
