    Greeting from Junction City, Oregon, USA

    Well now a little time has passed and the wife does not like the politics of Oregon so we have moved back to Texas, near Ft Worth. My Model III and 4 are still packed up and I have since acquired a 4P so at least it am still playing with my TRS-80s Greetings to all. Ross

    Enabling double sided operation on a model 4

    Well as for being a trusting soul, the M4GA arrived last night and I decided to give it the Smoke Test and then, of course, I let the smoke out.
