202374dd09 Added the PDP-10's four arithmetic flags along with a negate() function -- the first of our functions that actually needs to set those flags 2017-03-01 17:23:54 -08:00

e870fd6eec Fixed the accumulator update logic in all the PDP-10 half-word self-mode instructions, and started work on EXCH, BLT, and MOVE instructions (the BLT is a real odd-ball, and SIMH does some very strange things with the accumulator used by BLT, which we do NOT attempt to replicate; the strangeness is most noticeable when the accumulator is part of the range being transferred) 2017-03-01 16:00:48 -08:00

Jeff Parsons
0255b7b891 Implemented all four primary half-word moves (HLL, HLR, HRL, HRR) but none of the flavors (Z, O, E); need to test the primary instructions first 2017-02-27 09:50:28 -08:00

ef70ed74b3 Added support for parsing of values (ie, integers) greater than 32 bits, and fixed PDP-10 Bus writes (parameter order differs from other emulators) 2017-02-24 13:07:38 -08:00
Jeff Parsons
c0de732f76 Changed toStrBase() to accept a number of bits rather than a number of bytes, because bytes aren't always 8 bits (see PDP-10) 2017-02-24 10:58:56 -08:00

2ed076503f Since writeBitsMemory() must preserve unwritten bits, it can't use bit-wise operators (unless of course no bits above bit 31 are set, but it's not clear checking for that would be a win) 2017-02-22 15:33:18 -08:00
Jeff Parsons
ba7de38fbf Created PDP-10 skeleton 2017-02-19 15:22:58 -08:00

5940ef866d Changed the RESET button to *not* autoStart a machine when a Debugger is present, so that the Debugger can "cleanly" load bootstrap sequences and boot without side-effects (eg, unexpected interrupts) 2017-02-04 12:23:24 -08:00

df78f3c476 Switching to machine XML files that use a machine 'type' attribute rather than 'class'; 'class' can still be used to specify the machine type if 'type' is omitted, but going forward, it should only be used to specify an alternate CSS class 2017-01-31 22:06:13 -08:00
Jeff Parsons
f5625625d4 Somehow I failed to add two of the four machines to the release... hmmm. 2017-01-31 16:18:35 -08:00
