I didn't know about that first version of Basic, perhaps beacuse I started with an Amiga 500 and Extras 1.2 (with the MS Basic). I searched for a Workbench 1.0 and I encountered one, tested in ROM1.3 and yes: that Basic it's a version from Metacomco, but it's veeery simple. you can search for an image: 'Amiga Workbench 1.0 (30.XXX) (Commodore) (1985)', since i think it cannot be distributed. The version can be 30.xxx or 31.334. I hope this info will be helpful.
