And back then, you could expect your equipment to come with manuals that explained the tricks that could be done with their gear. e.g. If it had a serial or parallel port, the pins would documented, the function codes would be listed... Or, the sales division would get you the books for it. Now, everything's a black box. One client's bought this Roland, allegedly high-definition, digital video mixer (hi-def my left foot!, that means high definition, not just able to output low-resolution video with more pixels...). It has a port for the tally interface, that mentions nothing about how to actually use it. Sure, it lists several pins that you could have a tally signal on, depending on what mode its in. But nothing that defines what the modes are, nor the output voltages (TTL?, CMOS?, open-collector?, active low?). -- Don't send private replies to my address, the mailbox is ignored.
