it doesn't. it only works incidentally. The author isn't an EE and has designed a circuit as if an artist (or an AI) drew a picture of what a circuit looks like.

The weird topology voltage divider attenuates the signal. the op-amps buffer the output. The 470R resistors do nothing. The 1k/1k virtual ground does nothing.

The rest of the authors writings smell of /r/iamverysmart

once, when complaining to a colleague about our workplace and their hiring and staffing idiosyncrasies, I quipped "I should give <manager> a copy of TMMM". My colleague, without missing a beat said "You should give him two copies so he can read it faster"

There are a few dynamic pricing energy retailers in Australia too. It often goes negative, sometimes for many hours at a time. Usually it’s hard to make money off it because it’s often at times of the year and day that there is no need for heat/cooling.

it's actually persisted more recently. I just checked a High Sierra machine. "Messages" has an "Add Jabber Account" menu option. An it's recent enough that it plays nice with all my existing more modern iPhone/macOS etc iCloud messages.

In the slightly olden days, iMessage - or whatever it was called then - had a built in jabber client, and there was brief period (Sierra era?) that iMessage/iCloud could sync up all your messages across google and apple and SMS.

I _think_ it would have enabled this functionality, if anyone knew and/or investigated it.

Sometimes you can get away with just guessing pull-ups, but sometimes you need to calculate them. Drive strength, speed, line capacitance, line length, number of devices, supply voltage, threshold levels... it's all stuff you take into account when designing for I2C properly.

Reading the datasheets for both devices would probably avoid the problem.

I agree, it makes no sense. I am a real hardware electronics engineer and I don't understand his explanation. I believe the LDO could fail in a temperature dependent way. I do not believe the explanation.

Oh yeah, I remember that the battery was an odd size and expensive. I think it was 4.5V(?). We had a battery holder for some AAs hanging out the side.

I feel like our 16k bee had more than one ROM in it. I think you could boot into word bee by doing <reset>W and basic with <reset>M

I dont have the 16k bee to check. I kinda wish I did. The disk ones were more serious computers at the time, but I'm strangely more nostalgic for the tape ones. I think there's less magic associated with the tapes.

We had a 16k tape only bee before the disk one. I loved that they had battery backed SRAM. You could turn it off and come back later and your program was still there.

I just had a look, and didn't find anything, but I have a sneaking suspicion I have a copy of your game on one of my games compilation disks.
