Yep you are right Gary, I did not update the switch back for the new port on 
the V2-SMB.  Will add to the list.

Just finished updating the X” menu error yesterday! 

 

Let me know if you see anything else

Subject: Re: [N8VEM-S100:4665] Very minor 8088 monitor bug

 

John -

One more minor issue turned up tonight. 

I set up my Z80 and 8088 so that the TMA0 line does the swapping using the SMB. 
 I did this to keep the mapping of the LPT1: at 378H in preparation for MSDOS.  
If I understand things correctly this should be the preferred method??

It now switches fine from Z80 --> 8088 but wouldn't switch back.

A manual QOEE,00 does the trick, and adding this code to the V10.32 monitor was 
trivial.  I just added 

SW86_TM        EQU    0EEH        ;Output 00H to this port to switch to Z80 
Hardware.

and 

;------------- SWITCH CONTROL BACK TO Z80 (Master) ------------------

Z80:    in    al,SW86            ;This switches control back over to Z80 (old 
method)
    MOV    AL,00000000B     ;Or reset TMO to Z80 control.
    OUT    SW86_TM,AL    
    nop
    nop
    nop
    nop
    nop
    JMP    BEGIN

Extremely minor bug:

IDE_SIGNON3    Option "X" appears twice (copy A->B should be "Y").

It might cause somewhat trouble, if they accidentally select "X" to copy disks 
and end up over-writing.

DB    'E=Clear Sec Buff  F=Format Disk     I=Next Sec   J=Previous Sec',CR,LF
        DB    'L=Set LBA Value   N=Power Down      O=Disk ID    Q=LBA Display 
Test',CR,LF
        DB    'R=Read Sector     S=Seq Sec Rd      U=Power Up   V=Read N 
Sectors',CR,LF
        DB    'W=Write Sector    X=Write N Sectors Y=Copy A->B  Z=Verify 
A=B',CR,LF
        DB    '(ESC) Back to Main Menu',CR,LF
        DB    LF,'Current settings:- $'
