The makefile now works for Linux and most Unix's. Howevr, for Solaris and MacOS, you must first export the OSTYPE environment variable: > export OSTYPE > make Otherwise, you will get build errors. 1. New Features 1.1 3.8-0 1.1.1 SCP and Libraries - BREAK, NOBREAK, and SHOW BREAK with no argument will set, clear, and show (respectively) a breakpoint at the current PC. 1.2 GRI - Added support for the GRI-99 processor. 1.3 HP2100 - Added support for the BACI terminal interface. - Added support for RTE OS/VMA/EMA, SIGNAL, VIS firmware extensions. 1.4 Nova - Added support for 64KW memory (implemented in third-party CPU's). 1.5 PDP-11 - Added support for DC11, RC11, KE11A, KG11A. - Added modem control support for DL11. - Added ASCII character support for all 8b devices. 2. Bugs Fixed Please see the revision history on http://simh.trailing-edge.com or in the source module sim_rev.h.

This file contains template simulations for the firmware options that have
|
|
not yet been implemented. When a given firmware option is implemented, it
|
|
should be moved out of this file and into another (or its own, depending on
|
|
complexity).

/* Distributed System
|
|
|
|
Distributed System firmware was provided with the HP 91740A DS/1000 product
|
|
for use with the HP 12771A (12665A) Serial Interface and 12773A Modem
|
|
Interface system interconnection kits. Firmware permitted high-speed
|
|
transfers with minimum impact to the processor. The advent of the
|
|
"intelligent" 12794A and 12825A HDLC cards, the 12793A and 12834A Bisync
|
|
cards, and the 91750A DS-1000/IV software obviated the need for CPU firmware,
|
|
as essentially the firmware was moved onto the I/O cards.
|
|
|
|
Primary documentation for the DS instructions has not been located. However,
|
|
examination of the DS/1000 sources reveals that two instruction were used by
|
|
the DVA65 Serial Interface driver (91740-18071) and placed in the trap cells
|
|
of the communications interfaces. Presumably they handled interrupts from
|
|
the cards.
|
|
|
|
Implementation of the DS instructions will also require simulation of the
|
|
12665A Hardwired Serial Data Interface Card and the 12620A RTE Privileged
|
|
Interrupt Fence. These are required for DS/1000.
|
|
|
|
Option implementation by CPU was as follows:

Notes:
|
|
|
|
1. The E/F-Series opcodes were moved from 105340-357 to 105300-317 at
|
|
revision 1813.
|
|
|
|
2. DS/1000 ROM data are available from Bitsavers.
