Stephen,
I think it would be pretty simple to put an Arduino board inside the 4041 case - connected to the internal keyboard header, plus my resistor mod so the Arduino could direct drive serial into the 4041.
It might be easier to not worry about how long the 4041 takes to boot and just install an Arduino reset button on the back of the 4041. Press the Arduino reset button and the Arduino program would output the SET DRIVER and SET CONSOLE commands - which would require that the 4041 had the Program Development ROMs.
Does everyone on this thread already have those ROMs in their ROM Carrier?
Otherwise - the 4041 will only auto load an AUTOLD.IT program from tape - as the Program Development ROMs are required to run ASCII BASIC commands like SET DRIVER and SET CONSOLE.
Or someone needs to disassemble the Utility ROM and figure out how to make a PROM that would hold the AUTOLD.IT program to do the serial commands.
When I look at the 16-bit binary image of the Utility ROM, it looks organized similar to the Tektronix 4050 ROM packs, with a header, followed by ROM call names, each followed by the entry point address for that ROM call.
In addition the last 1024 bytes of the Utility ROM look like a template for the PROM image:
