PRU1 code split into multiple images 1. test functions 2. UNIBUS operation PRU1 bus latch interface Write byte/bits access not with MACROS (random optimizer influence), now with *_helper() procedures. Same timing, more determinism, much code saving. Nono more ASM code to write PRU0 XFER area. demo: menu to test UNIBUS signals directly rework "Arbitration" logic: now 3-fold Rework of UNIBUs arbtiration: NONE/CLIENT/MASTER - no Arbitrator (SACK penidng for 11/34 Konsole) (NONE) - phyiscal PDP_11 CPU is Arbitrator (CLIENT) - UniBone implements Arbitrator (MASTER) - Same PRU code loop handles all arbitration types PRU buslatch timing slower, for some problematic PCBs More aggressive bus latch selftest (mixed patterns, running on PRU now) Refinement of ready-to-run scripts - Adapted to changed "demo" menu - new name scheme <OS>_<boot- drive>_<PDP-11CPU> indicates - which OS is run - which disk emulation is used and what is the boot device - what is the (minimum) PDP-11 to run that Merged in Joshs DMA timing for 11/84 UNIBUS master cycles waits 350 us before MSYN, instead 150. Merged in Joshs DMA request queue multiple devices canrequest INTR and DMAs concurrently, will be put on the bus sequentially Merged in Joshs MSCP driver - Build RT-11v5.5 for MSCP - added boot loader "du.lst" MSCP run scrips 2.11BSD on MSCP on PDP-11/44 RT11 on MSCP Fix: image file sizing Disk image file exptend automatically if block beyond current file end is written
