I wanted to test the C2N232 device on the Oric-1. The bad news are that the Oric-1 tape format is not supported by the current C2N232 firmware, which only knows about symmetric pulses. Short pulses on the Oric-1 are symmetric (50% duty cycle), but the longer pulses have 66% or 33% duty cycle. Also, I could not fully figure out the logical tape format in reasonable time. The good news are that the Oric-1 was improved in the process. Since the Oric tape connection has been designed for regular tape decks, I had to locate a spot where the TTL-level cassette read and write lines are located. Now, this C2N interface for the Oric-1 has been documented at <URL:http://www.funet.fi/pub/cbm/documents/projects/other/c2n-oric1.html>. Marko Message was sent through the cbm-hackers mailing list
