Wild Hare Nova and Eclipse Emulator 
		Beta Update 05 Notes
		====================
		    [2024-Mar-19]


Enhancements
------------

1)	Memory sizes may now be set as KW, KB, MW and MW,
	format: SET MEMORY=<integer>[K|M][W|B]

2)	Nova and Eclipse CPU names have been modified to more accurately reflect their
	respective default configurations.  The update SET CPU <names> are:

		NOVA  
		NOVA_64K
		NOVA_840
		NOVA_3
		NOVA_3/D
		NOVA_4
		NOVA_4/X
		Eclipse_S/100
		Eclipse_S/130
		Eclipse_C/150
		Eclipse_S/140
		Eclipse_S/120

3)	Exam/Deposit Memory now recognize expanded Eclipse instructions;
	by default only Nova instructions assembled/dissembled.
	if Nova CPU emulated;
	command modifiers:
	-A	single (1) ASCII character, right half, octal if not displayable character
	-C	two (2) ASCII character, left/right, octal if not displayable character
	-E	override appropriate CPU check (support Nova + Eclipse instructions) (new)
	-L	dissemble Eclipse LEF instructions (new)
	-M	dissemble instruction appropriate for current CPU
	Note [Warning?]	all device names supported, Nova and Eclipse, so be careful of
			what device name you use.  This may be filtered in a later rev, but for now...

4)	LOAD and DUMP commands are expanded to include loading and saving memory contents
	to/from a file.  The default operation remains the same - loading a file
	in DG absolute binary format.  This may also be specified using the '-A'
	command modifier.  The '-M' modifier specifies loading/saving the contents
	of memory as binary words.  The '-S' option for the '-M' function specifies
	the bytes will be swapped.  (The default is big-endian saving/restoring.)

		LOAD [-A]      <filename>
		LOAD  -M  [-S] <filename>
		DUMP  -M  [-S] <filename>

5)	Instruction Tracing may now be invoked by setting the history save depth
	to '1'.  Setting the value to '1' enables the feature, setting it to '0'
	disables the feature.  History depth values greater than '1' behave
	as in previous releases.

		SET HIST=1		enable instruction tracing

6)	Options have been added to the LPT driver to handle the wide range of
	operating system and user functions (quirks?).
	A) the PIO character delay changed from 300 to 2 (simulates PIO LPTs better);
	B) A 'FLUSH' feature has been added to control 'fflush()' call at the end of
	   each line.  This may help indicate the true LPT file end-of-file value
	   by the operating system.

		SET LPT FLUSH

	C) A 'REOPEN' feature has been added to control LPT's file close/re-open
	   at the end of each line.  Although code introduces a much larger overhead
	   for LPT output, the host operating system should accurately reflect
	   the LPT file's size at the end of each line.

		SET LPT REOPEN

7)	A swap byte option was added to MTA to control byte swapping of the data
	contents of each mag tape record read/written.

		SET MTA SWAP

8)	A DPJ device driver was added to handle the various DG 5.25" disk
	drives [Desktop Generation diskettes, MPT diskettes, Jawa controller].

9)	Enhancements added to the DZP [DG Model 6060/6061/6067 "Zebra"-style
	disk drives].

	A) DZP autosize removed due to conflicts; explicit model number should be used;
	B) DZP special device 571 added for custom configurations;
	C) DZP 'SWAP' option added to swap data bytes

		SET DZP SWAP

	D) DZP 'READZEROS' option added to read zero data from sectors beyond the end
	   of the disk container file's size.

		SET DZP READZEROS 



Fixes
-----

1)	Fixed obscure 64KW memory support problem.

2)	LPT "Ignore character(s)" option did not properly ignore certain characters.



Miscellaneous
-------------

1)	Note that the MIPS meter is disabled by default.  The display update time, in seconds,
	is enabled by changing the RTC's 'MIPSsec' register to the number of seconds
	desired between MIPS updates.  For example, this command may be used to to update
	the main console display every five (5) seconds:

		DEPOSIT RTC MIPSSEC 5

2)	iCrap (oops, iPad/iPhone [iOS]) support added through use of iSH [rev Dec-2021];
	a few iSH console I/O quirks exist (ioctl issues?) but generally satisfying/ironic
	to run AOS on a tablet(!) or phone.
