I believe it'll require external RS-232 transceivers due to the design of the ones used on various DEC boards. As you say, whether or not the bus/CPU can keep up is another matter! Figure if I can get any real improvement out of it, I'll lay out a board and provide high-speed kits. Anyone know of a 40-pin UART with a FIFO? :) Thanks, Jonathan On Fri, Dec 15, 2017 at 1:34 PM, Ethan Dicks via cctalk < cctalk at classiccmp.org> wrote: > On Fri, Dec 15, 2017 at 9:38 AM, systems_glitch > <systems.glitch at gmail.com> wrote: >> vtserver does indeed work for transferring RL02 contents to a binary > image, >> suitable for use with SIMH or E11 or whatever. > > Yep.
