The Shine/1 is a seemingly rare Italian computer from 1983. The ROMs were posted on an Acorn forum as the owner thought it may be an Acorn Atom clone due to having similar hardware based on 6502, MC6847, 6522, and even the keyboard 'looks' very similar. That is where the similarities end.
There are no known manuals or software for this computer so emulation is based on photos only. At least it boots and BASIC runs, anything more is just guessing.
