1.5.9.1 - ND100e

ND100e

The ND100e (ND 100 CPU emulator) can load and run ND-100 :PROG files. This first release is only a POC (Proof of concept). Programs can be loaded and started, but will rather quickly be aborted when a unimplemented MON call is reached.

Download the ZIP file, unpack it to any directory and start ND100e from that directory.
Program files must, by default, be placed in the file system path SINTRAN\.

These are the implemented features in this POC release:

ND-100 CPU
32 bits floating point
All standard instructions (none CE and CX instructions, nor any privileged instructions)
Loads and runs :PROG files
1 bank only
A simplified Sintran III file-system (fixed directory and user)
A few MON calls (see the LIST-MON-CALLS command)

Commands

Type HELP at the NDe command prompt to get a list of all available commands. Lower-/uppercase doesn't matter and commands can be abbreviated as in Sintran III. F.ex the command LIST-FILES can be written as li-fi,,, with parameters on the same line or let NDe ask for them when missing.

CC [<Text>]

Comment, this command has no effect. The [<Text>] is optional and will not be asked for if not present.

LIST-MON-CALLS <List option>

Display a list of IMPLEMENTED (default) MON calls, or ALL the MON calls that are defined/exists in Sintran III.
There is a mark (after the % sign) for each MON call, which has the following meaning:

space = The MON call is fully or good enough implemented for this emulator.
* = The MON call is partly implemented (so far).
- = The MON call is not implemented at all.

LOAD-PROGRAM <File name>

Load a Sintran III :PROG file into the memory, ready for execution. The program is not started, this can be done by the RUN or RESTART commands. The program has to be a one-bank program in this POC release (but this is not checked by ND100e).

LOOK-AT <Space> <Address>

Look at MEMORY (code bank), ALT-MEMORY (data bank) or REGISTERS, starting at given address. The LOOK-AT command have some sub-commands:

LF or CR or space - Move to next address
ESC or . - Exit the LOOK-AT command
/ - Use the value in the current address as a new address and jumps to that address.
nnnnnn - A legal 16 bits octal value, will be stored in the current memory address (if deposit mode is enabled).
nnnnnn/ - A legal 16 bits octal value, will be used as the new address and jumps to that address.
DISABLED - Disable deposit mode
ENABLED - Enable deposit mode
MEMORY - Switch to page table 1 (code bank)
ALT-MEMORY - Switch to page table 2 (data bank)
REGISTER - Switch to look at registers

SUPPRESS-ERRORS <Suppress DOS errors> <Suppress MON errors> <Suppress SFS errors>

Suppress or enable some printouts of "low-level" error codes, mainly used for debugging. Enabling these printouts will usually interfere with the output from the running program.

DOS - DOS file system error messages.

MON - MON call error messages.

SFS - Sintran file system error messages.
