Sent from my ZX-80! Thats awesome. I think we had the next-gen ZX-81 which came with 2K of RAM instead of 1k. That's right before I think Timex or Texas Instruments bought the patent. We were all excited when Dad bought the 16k RAM brick. He built a bracket to hold it in b/c it as so wobbly.
Oh, btw, I've had random brightness settings too. I'm sure its a quirk somewhere. Say what you will about Android in general or T-bolts in particular. This is a helluvah lot smoother and more stable than the last platform I was on.
Sent from my Radio Shack TRS-80 using my fingers.
