Here are some that are used at SLAC and SPEAR:

swfRecord - scaled waveform record from BESSY, same as waveform but with raw offset and vertical scale factor and offset.  Used in reading scopes.

wftimeRecord - waveform with both time and Y, assumes both are double, for input waveforms only.  PREC, EGU, HOPR, LOPR provided for both time and Y.  ESLO and EOFF provided for Y.  NORD monitor goes off when changed (unlike waveform which I think is a bug).  Used in reading time/value arrays from Keithley DVMs.

sSub - special subroutine, same as sub except with 26 inputs (A to Z)

One custom record per six custom RF VXI modules which are loaded with features and have very large address maps plus DSP interfaces - each record can be thought of as a combination of many ai/ao/bi/bo/sub/seq/waveform records where the bulk of the processing is done in device support.  These records are monsters but I think new people assigned to maintain them come up to speed more quickly - it's easier to match the hardware documentation and address maps with the software.
