Hmm, without checked it might be possible to redirect lilo to a serial
port, infact I would be surprised if it did not.

As I told you I never done this but it looks like a "standard" inverter,
such as 74LS04, or the CMOS compatible 74HC04 i think any 74xx04 will do.

The 4049 is a "pure" CMOS inverter but no worries, try the 74 they are
usually easier to find.

Case, you mean the physical size of the cap or the value? stick to the
value, the physical size is no problem.

They are used to charge the voltage up to RS232 levels(+/-12 Volt).

Bingo, that must be it sometimes my mind is somewhere else.

Goodluck and PLS maka a posting here once you done with it, the type 5
