Yeah; how could we have missed that /LPS signal all this time... Thanks, Kurt! ----- Original Message ----- From: Stephen Adolph To: [email protected] Sent: Thursday, June 28, 2018 1:58 PM Subject: Re: [M100] Low power check
Wow. Very nice. Learn something new every day. On Thursday, June 28, 2018, Kurt McCullum <[email protected]> wrote: Will, Found it in the Robert Covington's M100 ports/registers file. Port D0 (208) is where the low power signal is. The file indicates this is the same for both the 100 and 200. PRINT INP(208) That command should give you the status of the power. Bit 7 is the indicator so the value will change by 128. Kurt On Thu, Jun 28, 2018, at 10:32 AM, Kurt McCullum wrote: It's actually a INP(216) command not a PEEK(216). I didn't realize that when I first posted. But the memory locations on the 200 would be different than the NEC. So for the NEC, in BASIC the following command would show the value: PRINT INP(216) Kurt On Thu, Jun 28, 2018, at 9:53 AM, William Winter wrote: FYI... I just tried the PEEK (216) on my Model 100 and it returned 85 with both the battery light on and off. -Will On Thu, Jun 28, 2018 at 12:42 PM Kurt McCullum <[email protected]> wrote: That's what I was afraid of. However, I did find something that is worth a try when I get home tonight. In the NEC 8201 technical manual (yes I read these things) on page 256, it looks like bit 7 of memory location D8 (216) is set when there is a low power signal. If that is correct, a PEAK(216) which returns a value greater than 127 should indicate a low power state. But I'll have to test this later since I am not in front of the machine.

I would assume that the 100/200/NEC all have different locations in memory but is this possible? Kurt
