Re: Yet another MK14 tape interface (ESP32).
The only change I would make would be the "300uS between all transitions", I currently use 60uS for each bit (120uS total for bit), and 180uS delay after each byte to allow MK14 to process the byte received. These can be used when no VDU card is attached that interrupts the MK14 CPU.
Currently I use 180uS (bit) and 360uS (byte) when RealView VDU card is being used. |

Re: Yet another MK14 tape interface (ESP32).
Also, the FastLoader can also be used with SCIOSv2. The FastLoader is loaded first into RAM using the original MK14 tape interface, subsequent loads can use the FastLoader.
