Re: [M100] M200 and bad RAM??

OK great! I find the T200 memory management leaves a lot to be desired. Even simple things like deleting a Basic program or Text file can leave the memory still occupied with nothing showing on the screen. Although I do like the screen real estate and keyboard on the T200 :) On 19/10/17, 11:58

Re: [M100] REX Castellated board

When I built an original REX I had a similar problem turned out there was a bad solder joint on the CPLD. The soldering looked fine from a visual inspection but when I used my dental pick to check each joint one of the pins moved. Fixed the bad joint and the board worked fine. Might be

I ordered a set only a couple days ago, so it'll be a week or so for me. On Oct 19, 2017 7:25 AM, "Stephen Adolph" wrote: Has anyone made a REX successfully with that modified PCB yet? I would like to know if that artwork is good or bad. ..Steve
