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 John From: n8vem...@googlegroups.com [mailto:n8vem...@googlegroups.com] On Behalf Of geka...@gmail.com

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

Subject: [N8VEM-S100:4625] Very minor 8088 monitor bug 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.
