I have a friend who years ago twisted my arm to get me into Clover. Back then the original Clover modem, the PCI-4000 was arguably more costly than the SCS modems in constant dollars. We used to keep skeds and use it conversationally - he seemed to really enjoy the quasi-full-duplex operation where we could both be typing at the same time and our two-way communications were going along with the ACK and NACK signals. Eventually we gave up on Clover, partly because we both got busy with other things, but also because Clover seemed to have a particular shortcoming: when the channel quality deteriorated it would keep trying unsuccessfully to send a long block, instead of dropping back to a shorter block that might have a chance of getting through. But when it worked we did enjoy the error- free conversations under band conditions that were too bad for the only other keyboard mode we had at the time, which was RTTY.
