The NEC REX has pins that insert into a socket, unlike the Model 100. I am always careful about how I insert the module into it’s socket. Fred

I have two of them that work, and one that doesn't. I was able after about thirty minutes to a fresh install of the REX software on one of my NEC machines, but the other one still hangs up during the stage where the memory banks are being erased It has to be a subtle difference between the 8201 and the 8300 that causes it. I gave up on the one and inserted a TS-DOS Rom into it instead of the REX for now. All of my model 100 computers did well with the update. It was quick and easy. I still prefer the Model 100 keyboard to the NEC PC-8300 keyboard. There is a slight difference that takes getting used to. I also prefer the Model 100 keyboard to the Notebook PC's that I have. The Capacitance mouse is a real nuisance, and I can't usually turn it off. Fred Whitaker On 4/6/2020 12:16 AM, Stephen Adolph wrote: > build 260 for REX is on the wiki.
