History (partial):
|
|
|
|
2003-11-15 Changed default value of TTO STIME to 200. It was
|
|
defined using a constant from sim_defs.h which was
|
|
changed from 10 to 100 at some point. APL\1130 has a
|
|
sychronization bug & hangs if the console output complete
|
|
interrupt occurs between the XIO SENSE and WAIT instructions.
|
|
This bug is hit frequently if the delay time is set to
|
|
100 instructions. 10 worked reliably, but is really not realistic,
|
|
and 200 may not be adequate in all cases, but we'll try 200 for now.
|
|
|
|
2003-11-00 Updated GUI to allow drag and drop to simulated card
|
|
reader, tear-off from simulated printer
|
|
|
|
2003-07-10 Fixed disk and console terminal bugs uncovered by
|
|
APL\1130. Added APL keyboard and output font support
|
|
to enable use of APL\1130. APL will be released soon.
|
|
|
|
2003-03-18 Fixed bug in asm1130 that produced an error message
|
|
with a (legal) offset of +127 in MDX instructions.
|
|
|
|
Fixed sign bug in 1130 emulator divide instruction.
