[HECnet] KLH-10 TOPS-10 DECnet Executor Configuration Persistence

_CON_ditions _O_ut; it's a PDP-10 I/O instruction. This is what communicates with the Idler device that you put at address 700. At a very high level, PDP-10 is split into two halfs, instructions for 'conditioning' the device and reading its condition (or status bits) and instructions for performing I/O. On the 80x86 platform, IN and OUT are used, with status registers being at different addresses then data registers. Note: I have ignored DMA, block transfers and PI. The Idler will actually handle data transfers, but that is another story. On 3/11/20 9:53 AM, Supratim Sanyal wrote:
