The other big gift to UNIX from ITS was Eric Shienbrood's more(1) command [discussed elsewhere]. This brings us back to the topic -- the need for more(1) as either built-in like ITS or as command [UNIX] is lost with today's infinite scroll buffers. Much less, what was fsck(1) original name at CMU ;-) or why tjk wrote the first version. 4. Edit a driver and recompile the kernel to change partition sizes. Doing the same with adb(1) on the kernel binary as well as understanding disk geometry and calculating the HEAD/CYL/SEC to block numbers properly. > 6. Wonder whether something with a serial port is a DTE or a DCE. How about knowing what DTE and DCE mean in the first place. Along with why CTS/RTS (HW) flow control was really needed at high speed. Why the UNIX community tended to migrate to aftermarket DH11, instead of DZ-11s - particularly for UUCP > 8. Adjust jumpers on a peripheral How about having the proper jumper sizes. Or realizing the DIP switches were not actually toggling properly so the address was wrong. > 9. Insert or remove wires for IRQ bus continuity Know what a BUS GRANT card does. ᐧ
