Notes For V3.10
|
|
|
|
3.10 is mostly an attempt to get aligned with the current head of the
|
|
GitHub 4.0 sources. While the core libraries and SCP have diverged too
|
|
far for real forward and backward compatibility, enough 4.0 workalikes
|
|
have been added to allow much closer convergence of the two streams.
|
|
|
|
3.10 will provide the basis for my future simulation work.
|
|
|
|
|
|
1. New Features
|
|
|
|
1.1 SCP and libraries
|
|
|
|
- -n added in ATTACH, meaning "force new file"
|
|
|
|
1.2 1401
|
|
|
|
- option to read cards from the console terminal window
|
|
- option to print line printer output in the console terminal window
|
|
|
|
1.3 1620
|
|
|
|
- tab stop support added to console terminal
|
|
|
|
1.4 PDP-8
|
|
|
|
- LOAD command now supports multi-segment binary tapes
|
|
|
|
1.5 PDP11
|
|
|
|
- added RS03/RS04 Massbus fixed head disk support
|
|
|
|
|
|
2. Bugs Fixed
|
|
|
|
Please see the revision history on http://simh.trailing-edge.com or
|
|
in the source module sim_rev.h.

3. Status Report
|
|
|
|
The main branch of SimH is maintained in a public repository
|
|
|
|
https://github.com/simh/simh
|
|
|
|
under the general editorship of Dave Hittner and Mark Pizzolato. The
|
|
3.X branch provides a simpler environment for debugging, for my taste.
|
|
|
|
Because of divergences between 3.X and 4.0, certain features in 4.0
|
|
cannot work in 3.X and are not present:
|
|
|
|
PDP11/VAX/PDP10 - DUP11 and DMC11 synchronous network interfaces
|
|
|
|
PDP10 - front- end keep-alive timer
|
|
|
|
H316 - IMP network interface
|
|
|
|
In addition, the PDP11 DZ, VH, XQ, and XU implementations are significantly
|
|
"down rev" compared to 4.0, due to differences in supporting libraries.
