My October 1978 DS-1 is from the 7500 batch.
Does anyone know if it's a revision C or B? It would save me from having to open it up! I'm too lazy....
It's probably a revision "C", I just made a research and found pictures of a 7400 and it is a "C", so your 7500 is, most probably, also a "C".
7100 = A (confirmed)
7200 = B (confirmed with Google image search)
7300 = ?
7400 = C (confirmed with Google image search)
7500 = C (confirmed with Google image search)
7600 = C (Mine)
7700 = C?
7800 = C?
7900 = C (confirmed with Google image search)
