65eb821710 Well, apparently the PDP-10 MUL instruction really DOES store the high-order word first, and it only stores the low-order word if the destination is an accumulator (weird) Jeff 2017-03-07 14:09:24 -08:00

3d4795bbe4 Updated the Int36 class with support for both signed 71-bit values (my original double-length format) and 70-bit values consisting of two signed 35-bit values (DEC's double-length format) Jeff 2017-03-06 15:48:31 -08:00

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 Jeff 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) Jeff 2017-03-01 16:00:48 -08:00

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 Jeff Parsons 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) Jeff Parsons 2017-02-24 13:07:38 -08:00
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) Jeff Parsons 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) Jeff 2017-02-22 15:33:18 -08:00
b8b774696b 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) Jeff Parsons 2017-02-19 15:49:08 -08:00
ba7de38fbf Created PDP-10 skeleton Jeff Parsons 2017-02-19 15:22:58 -08:00
b1d16c979a Removed obsolete version of Int36 (using signed integers internally); sticking with unsigned integers internally not only simplifies some of the existing logic, but will make it easier to add logical operations later (eg, AND, OR, XOR, etc) Jeff Parsons 2017-02-18 09:36:47 -08:00
acdf89ec54 Make Int36 toDecimal() more paranoid (we want perfect output, or no output at all) Jeff Parsons 2017-02-18 09:28:43 -08:00
