From 8ac9b564e7b253a2724346893e8336eb0851ca6c Mon Sep 17 00:00:00 2001 From: Lars Brinkhoff Date: Tue, 17 Jul 2018 13:49:07 +0200 Subject: [PATCH] Update Rubin 10-11 documentation to match code. ITS configuration has the Rubin 10-11 in the 3,,0-3,,777777 range. The documentation says it's one moby lower. Two more PDP-11s were attached at some point. --- doc/sysdoc/_calls.127 | 11 ++++++++--- 1 file changed, 8 insertions(+), 3 deletions(-) diff --git a/doc/sysdoc/_calls.127 b/doc/sysdoc/_calls.127 index ff89dd74..5cdf6ce7 100755 --- a/doc/sysdoc/_calls.127 +++ b/doc/sysdoc/_calls.127 @@ -4255,13 +4255,13 @@ T11MP: PDP-10 to PDP-11 map PDP-10 pages are mapped into segments of variable size in the PDP-11's memory. The PDP-10 to PDP-11 page map is also directly addressable in memory (it currently lives in absolute locations - 2,,776000 - 2,,776377).

There are 256. such entries, one for each + page in the range 3,,0 - 3,,777777, which are the addresses fielded by the PDP-10 to PDP-11 interface. ITS allocates these pages and their corresponding map entries randomly as needed. When the PDP-10 attempts to access a physical address in the range - 2,,0 to 2,,777777, the interface uses the 776000 bits to index + 3,,0 to 3,,777777, the interface uses the 776000 bits to index the map words. If the appropriate map word does not have its valid bit set, the memory is considered non-existent. The same is true if the reference would violate the protection bounds. @@ -4302,6 +4302,11 @@ T11MP: PDP-10 to PDP-11 map 4 The Logo pdp11/45. 5 The Micro-Automation pdp11/45. + The following PDP11s were added at an unknown date. + + 6 The Vision 11/40. + 7 The pdp11 that runs the AI Chaosnet interface. + Errors: 1 NO SUCH DEVICE
