It would be a lot easier if everyone picked top or bottom posting when they reply but I digress.... My suggestion to use the "monitor method" is a stop-gap just to get to the point of loading in something useful when no other means was workinhg. I agree any process that has no checksum will be unreliable. Whatever.. . Let's say for now you have at least the monitor method until something better comes along. As far as splitters for serial, they're plentiful on ebay...serial switch boxes that is. If you set your modern terminal sodtware to match the same settings as the swtpc vintage terminal you would be able to switch between them. I sometimes load in programs using a modern terminal to download a papertape into the computer then switch to a vintage terminal for use. Simple...assuming you can get your modern machine to match the vintagr, and you have the cables. Otherwise you'll have to buy/make them. Bill
