Thanks Darrel, but I did say in my post at 15:51 ... I have tried the Melabs programmer 4.32beta
Woops. My bad.
As soon as I see 2.46 beta, I stop looking for anything else.

I would be curious what happens with this program.
Since about the only difference between the 628A and 648A programs will be clearing the additional RAM in BANK2.

This program tries to clear the same memory without the clear statement.
It doesn't do banks 0 or 1 because they were already checked with the 628 program loaded in the 648.

Code:
DEFINE OSC 20 

Idx     VAR BYTE
B2RAM   VAR BYTE[80] BANK2
COUNTER VAR BYTE

FOR COUNTER = 0 TO 10 ' confirms beginning of program
    LOW PORTA.0
    PAUSE 250
    HIGH PORTA.0
    PAUSE 250
NEXT

TEST:

FOR Idx = 0 TO 79
    B2RAM(Idx) = 0
NEXT Idx

LOW PORTA.0   ' turn LED on to indicated completed
              ' may need HIGH don't know which way the LED is.
STOP
Probably nonsense, but I'm still curious.
