Hi Peter ... or anyone else who has successfully used it.

Does the Colour Maximite 2 have MM.STARTUP support (as per the PicoMite ?)

It's not mentioned in the manual, but there is at least some vestigial support in the source code.

Best wishes,

Tom

If I had one I would test it with this:-

Sub MM.STARTUP
Print "Hello from MM.STARTUP"
End Sub

If mine weren't currently in the back of a drawer so would I. :)
I haven't got the current firmware on either so it might take me some time to sort them out.

You could set it to use OPTION RAM then it will look for AUTORUN.BAS on boot rather than booting a program in flash.

Oh, thanks for the reminder

I have just acquired a PS/2 keyboard but I couldn't remember why I wanted one

Maybe I can finally test my CMM2

Yes, I was being lazy and trying to get one of you to do the work

.

Upon experimentation I think that whilst undocumented MM.STARTUP is implemented (provided you have the default OPTION FLASH not OPTION RAM) and on startup the CMM2 will first run the MM.STARTUP subroutine of the program currently in flash and will then run any of its other content - I believe this is what the PicoMite does to - though [BUG] it appears that the CMM2 is also incorrectly pre-populating the prompt line with the contents of the last line of the program currently in flash.

With OPTION RAM set the program named "autorun.bas" is executed and any subroutine called MM.STARTUP that it contains receives no special treatment.

However it also appears that attempting to use an "EXECUTE RUN" construct from within a startup program causes the CMM2 to hang:

> option list
CURRENT VGA mode 800x600 RGB332
CURRENT DISPLAY 50,100
OPTION AUTORUN ON
OPTION USBKEYBOARD UK

> list "autorun.bas"
? "In autorun.bas"
RUN "foo.bas"

> list "foo.bas"
? "In foo.bas"
End

> list
? "In autorun.bas"
RUN "foo.bas"

<<Reset the CMM2>>

> In autorun.bas
In foo.bas

>

But if you change "autorun.bas" to:

> list "autorun.bas"
? "In autorun.bas"
Execute "Run " + Chr$(34) + "foo.bas" + Chr$(34)

And reset the CMM2 then the output is:

> In autorun.bas
<<HANGS!!!>>

You might argue that "If it hangs then just use RUN without EXECUTE", but that isn't necessarily possible c.f. configuring "The Welcome Tape" to startup (you can use RUN to call "welcome.bas" but then that needs to use "EXECUTE RUN" to launch the actual menu) (see https://www.thebackshed.com/forum/ViewTopic.php?FID=16&TID=16474&LastEntry=Y#240801#240801).

Any chance of you investigating Peter ?

Best wishes,

Tom
