Lars Brinkhoff	feb155fbc4	H316: Convert IMP long leaders to short, and vice versa. ... This adds the modifiers CONVERT and NOCOVERT to the HI units. When enabled for a unit, 1822 messages will transparently be converted. IMP-to-host messages are converted from the old, short (32-bit) format to the new, long (96-bit) format. Host-to-IMP messages are converted in the other direction. The motivation for this feature, is that the currently running IMP software is from 1974 and only supports short leaders. Some operating systems are from a later era, and only support long leaders.	2025-01-17 16:35:53 -05:00

Tony Lawrence	c093bcdcf6	PDP11: RP11: Implement original RP11 controller flavor ... Studying RSX11M source code I found out that the original RP11 controller (vs. -C and -E later versions) was still supported in the software, and notably UMD (User Mode Diagnostics) was still capable of handing it and dealing with its testing, even in much later OS versions (compared to when the original RP11 was phased out). The change in this commit basically implements that flavor (which only supported the RP02 drives), and also makes a few minor fixes / cleanups for the device code, here and there. The default mode for the RP11 controller remains the more widely used -C/-E version, but if so desired, it can be downgraded to support its predecessor with the "SET RR <type>" command now.	2024-09-04 13:39:47 -04:00

Charles Anthony	aea2634940	IBM1130: Fix address computation overflow ... In sim_instr(), the effective address is computed; for the case of TAG (index register addressing), the contents of the specified index register is added to the effective address, but the result is not masked to 16 bits as per the hardware functionality. Adding a a 16 bit mask operation fixes the issue.	2024-06-17 14:04:19 -04:00

Tony Lawrence	100f351575	PDP11: RP11: Interrupt on IE+RESET+GO ... Recent analysis of the 2.9BSD kernel revealed that RP11 was expected to interrupt on control RESET function if IE bit was also set. Documentation was not very clear of the fact, saying in one place that RESET+GO does not interrupt (which is not contradictory with the above because it does not mention IE). In other place, however, it says that IE always causes interrupt when DONE is asserted. Thus, since RESET does assert DONE, an interrupt should be posted if IE is set. The autoconfig binary from 2.9BSD uses this feature of RP11 to check the presence of the controller. Formerly RESET was always clearing RPCS with DONE unconditionally, and that reset IE as well. This patch makes sure that the IE bit is preserved, and if set, it posts an interrupt when RESET asserts DONE.	2024-06-13 21:42:44 -04:00

B. Scott Michel	c37d26a370	IBM 1130: GUI resource file, RegSanityCheck fix ... - Add the missing ibm1130.rc GUI resource file to the Windows build so that the GUI renders correctly. - Set the add_simulator TEST_ARGS to "-g" to fix an edge case Heisenbug encountered during Github CI/CD tests where ibm1130 appears to hang indefinitely on the Windows runners. The cause is the GUI's Pump() thread function being prematurely terminated before all GUI resources are acquired. The net result is an infinite loop in the MS C runtime trying to exit the process with unstable internal state. (Separate patch: synchronization across main and Pump() threads to ensure resource acquisition completes.) This issue never shows (cannot show) up on non-Windows platforms or the SIMH makefile. - Ibm1130/ibm1130_cr.c - Fix printf() warnings (format should be long, not int) - Signed/unsigned mismatch, size_t for array indexing - Comment out the unused trim() function. - Ibm1130/ibm1130_cpu.c, ibm1130_gui.c: Remove undefined static functions.	2024-06-08 13:51:23 -04:00
