Hi Kurt - "Watchdog" is a Tracy Allen pgm that's documented here - Scroll down a bit... http://ftp.whtech.com/club100/ref/ My stuff is in storage right now, but what I did is use the background task interrupt to increment a secs/mins/hours counter, & display the result where the M$ blurb is

Jack, Glad to here it isn't just my experience. Is your watchdog.co available? I've toyed with building a battery pack with 10 1/3 AA cells (2 banks of 5). This would give me 6v but the capacity would be less than just using 4 regular cells. I have two dead 8201's that both still have good power s

Kurt - NiCds are all I use in my 8201a's - They both act identically to yours. Years ago I rearranged WATCHDOG.CO to display elapsed-time where the M$ blurb usually appears, which scratched my itch for a little more battery certainty. I reset it when I change batteries - Not perfect, but

Yes, I'm comfortable with soldering a new resistor, but the NEC was originally sold with both a NiCd battery pack and a standard Alkaline battery pack. The only difference between the two is the charging resistor and a jumper. I would assume that the power supply would know, based on the type of pa

Kurt, I'm sure it would be possible to adjust the threshold where the LED illuminates to match the new battery chemistry. It's probably a resistor change. Are you comfortable with soldering on the logic board? Doug On Wed, 13 Jun. 2018, 12:36 pm Kurt McCullum, wrote: > I've got several batte

2018-06-12 Thread Kurt McCullum
I've got several battery holders for my NEC units. I have converted a couple to recharge batteries by following the instructions on Web8201.net. The 71.5k resistor was the hardest part to find and in the end I bought 100 of them. The batteries charge fine, and work ok. But what I notice is that the
