Jeff Parsons	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

Jeff	0aa88da301	Updated information on PDP timings	2017-02-23 09:02:48 -08:00
Jeff Parsons	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)	2017-02-19 15:49:08 -08:00
Jeff Parsons	ba7de38fbf	Created PDP-10 skeleton	2017-02-19 15:22:58 -08:00
Jeff Parsons	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)	2017-02-18 09:36:47 -08:00
Jeff Parsons	acdf89ec54	Make Int36 toDecimal() more paranoid (we want perfect output, or no output at all)	2017-02-18 09:28:43 -08:00
Jeff Parsons	c1ab8918bd	Make Int36 toDecimal() more paranoid (we want perfect output, or no output at all)	2017-02-18 09:23:45 -08:00

Jeff Parsons	3f65a1b770	Simplify Int36 bit handling (only affects division)	2017-02-18 08:50:24 -08:00
Jeff Parsons	55bb0252b7	Be more specific about detected errors	2017-02-17 13:38:34 -08:00
Jeff Parsons	cff039f6a5	Added the reduce() function, to reduce 72-bit extended values to 36-bit values, magnitude permitting	2017-02-17 13:31:17 -08:00
Jeff Parsons	689adca2a7	Comment updates	2017-02-17 12:15:48 -08:00
Jeff Parsons	688fa635c8	Clarified the operation of negate(), added an explicit extend(), and made toDecimal() more robust (in case we end up with goofy values)	2017-02-17 11:52:36 -08:00
Jeff Parsons	80756041f3	Int36.toDecimal() now supports any value up to 72 bits	2017-02-16 15:58:50 -08:00
Jeff Parsons	4de50acdf1	Added alternate Int36 addition/subtraction overflow/underflow detection logic as a verification check	2017-02-16 14:05:05 -08:00
Jeff Parsons	048a10aac6	Fixed toDecimal() for large extended Int36 values (although there are still some very large values that trigger an error)	2017-02-15 23:43:23 -08:00
Jeff Parsons	4d94b5812b	Cleaned up divExtended()	2017-02-15 22:27:03 -08:00

Jeff Parsons	798fae1898	Updated Int36 comments	2017-02-15 16:35:15 -08:00
Jeff Parsons	6bc0d8ac49	Trying a second approach to the Int36 class that sticks to unsigned numbers internally (only downside so far is that the detecting arithmetic overflow/underflow is more work and hasn't been implemented yet)	2017-02-15 16:16:32 -08:00
Jeff Parsons	259dd7d66f	Updated comments	2017-02-15 11:54:16 -08:00
