Back then I used the Transformer a lot.
It was the main disk and a DOS one with GWBasic also included.
It worked only on A500, I think even real fast ram was a trouble.
A few days ago, I tried to replicate the memory and had no A500 with me.
I managed to do that with WinUAE and a DOS disk from a bridgeboard which I converted with the disk custom setting.
Transformer (if this disk is in your case) play with 360K DOS disks.
