        *   [high-speed paper tape punch][pp8i] and reader
        *   DECtape types [555][dt555] and [TU55][tu55]
        *   auto-restart type [KR01][kr01]
        *   [Type 182 EAE][t182]
        *   interrupt controller
        *   line printer type 645 (Analex?)
        *   and many lesser-known peripherals!
    *   Ability to define new instructions
    *   Zero-page addressing
    *   Indirect addressing
*   `EXPUNGE`, `FIXTAB`, and `FIXMRI` pseudo-ops to augment or redefine the predefined instruction set
*   `PAUSE` assembly output, giving the user time to do manual things while the assembler waits
*   Radix selection with `DECIMAL` and `OCTAL` pseudo-ops
*   `DECIMAL` and `OCTAL` pseudo-ops for radix selection
*   `FIELD` pseudo-op to select the core memory field

We give this list not to try to replace the PAL-III manual, but instead to allow searching this document for language features. You may assume that assemblers listed below also support these listed features, especially within the PAL genealogical line; we call out the exceptions below.
