Notes For V3.8

Browse Source 
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

savings to allow programs to load in E-Series systems, in addition to
accelerating these common operations.
M-Series microcode was never offered by HP. However, it costs us nothing to
enable double-integer instructions for M-Series simulations. This has the
concomitant advantage that it allows RTE-6/VM to run under SIMH (for
simulation, we must SET CPU 1000-M, because RTE-6/VM looks for the OS and VM
microcode -- which we do not implement yet -- if it detects an E- or F-Series
machine).
There was no equivalent M-Series microcode, due to the limited micromachine
address space on that system.
Option implementation by CPU was as follows:

Notes:
1. The E-Series opcodes are listed in Appendix C of the Macro/1000 manual.
These should be the same opcodes as given in the 93585A manual listed
below, but no copy of the reference below has been located to confirm
the proper opcodes. This module should be corrected if needed when such
documentation is found.
1. Opcodes 105335-105337 are NOPs in the microcode. They generate
unimplemented instructions stops under simulation.
2. The action of the self-test instruction (105320) is unknown. At the
moment, we take an unimplemented instruction trap for this. When
documentation explaining the action is located, it will be implemented.
2. This is an implementation of Revision 2 of the microcode, which was
released as ROM part numbers 93585-80003, 93585-80005, and 93585-80001
