I'm building up my 128 flat and want to add the rom version of the super 81 utilities. Is this a hacked version or was it commercially available? I haven't been able to find much info about it, but an eBay search has turned up some homemade versions for sale. If I can get a licensed copy, I'd prefer to do that but if it's a hack or freely available I can just burn my own if I can get the image.
Thanks in advance!
