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) 2017-03-07 14:09:24 -08:00
Jeff
7e207db2a1 Added PDP-10 JSP and JFCL operations (which seem to be the simplest means of getting and setting the processor flags) 2017-03-07 13:44:43 -08:00

affaa1075c Finished the PDP-10 Move Magnitude opcodes, along with the Push Down and Pop Up opcodes (uncovering some SIMH weirdness along the way) 2017-03-02 16:38:00 -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 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

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

8f0b808b1e 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 22:05:04 -08:00

f4f6181923 v1.31.0 marks our first transition to ES6 classes, but only for PDPjs initially (which is why there must be both /lib and /es6 files in the shared folder for now) 2016-12-18 11:31:55 -08:00

b54253acf9 Numerous changes to make paper tape configurations more consistent with disk configurations. This allows all devices to share the machine-wide "autoMount" configuration object, now that the PC11 has a proper device name ("PTR"), making its properties distinguishable from those for RK11 and RL11 drives (eg, "RK0", "RL0", etc). And all the tape/disk components now use "Load" functions to connect a tape or disk to a device ("Attach" is deprecated). And finally, all tape/disk components now support operations to deposit their media directly into memory -- although in this case, the names of the operations are necessarily different: "Read" for tape images, "Boot" for disk images. The difference is partly historical convention but also reflects the fact that a "Boot" operation is more limited: paper tapes were designed to be completely loaded into memory, whereas bootable disks are designed for only the first sector to be loaded and executed. Also, paper tape images are now flagged as non-auto-starting, because they often require some user action (eg, loading another tape, setting some switches, etc), whereas disk boot sectors are flagged as auto-starting (see the fStart parameter of the loadImage() interface in the RAM component). 2016-12-03 14:49:51 -08:00
