Where do I buy Amiga 1200 kickstart 3.9?

I installed custom burned 3.9 ROMS in my A4000 because I wanted to eliminate the double reboot.  It wasn't as compatible as the 3.1 ROM.  One of the things it wouldn't do is the double-mouse button on boot up plus LoadWB command, a very useful way to get into workbench when something is stopping your amiga from booting.

I put back the 3.1 ROMS.

Kickstart 3.9 doesn't officially exists but the newer modules from OS3.9's BB2 "AmigaOS ROM Update" that resides in Devs folder can be used to replace the older Kickstart 3.1 modules to form it.

These modules are the following:



Using these instead of the 3.1 ones (as I wrote to my guide) will grant you a Kickstart 3.9 ROM that you can use it via kicking it (like for example with ACA accelerator's ACATune utility) or burn it into real 1MB EPROMS and mount it on your Amiga replacing the former Kickstart 3.1.

It works just fine and I've been using many of those for years

Can you try this for me on your system:

Hold two mouse buttons down on boot.  Boot with no startup. Type LoadWB in the shell window.  Tell me what happens?
