Jeff 6bd24c5347 Fixed how index operands are assembled into PDP-10 instructions, which was an unexpectedly convoluted process (they are NOT masked to 4 bits, shifted left 18 bits, and OR'ed into the opcode; instead, they are computed as a 36-bit value whose left and right 18-bit halves are swapped and then ADDED to the opcode, which means that an instruction encoded with indexing may not end up using indexing at all, depending on where all those bits fall)		2017-04-05 12:38:36 -07:00

Overview

This PDPjs module for PDP-10 Machines was added to the PCjs Project in 2017.

The module is currently comprised of the following components, as listed in package.json (see the pdp10Files property):
