I should try and see if it is actually reading the ctrl-brk, what if there is a problem with the keyboard or key decoding? Looking at the source it looks like it will trigger a cold boot when it senses a change in memory size or a new option ROM being installed to.
The silly LA software will only do parallel decoding based on the edge and it wont work properly with the /RD* signal alone as the clk source. The LA software's built in 'simple parallel' decoder looks at the state of the other channels when the channel designated as clock changes state and gives you a dump of the hex value of the bus at that time. It is a bit frustrating really how limiting the software is.

It does retain it but there is the potential for random data to be in the RAM on each power cycle without the ctrl-break. With the NiCd on board the memory would be in the same state as setup during the clean boot. So far everything you have done looks good. _____ From: M100 <[email protected] <mailto:[email protected]> > on behalf of Jeffrey Birt <[email protected] <mailto:[email protected]> > Sent: Monday, May 7, 2018 03:12 To: [email protected] <mailto:[email protected]> Subject: Re: [M100] SPAM-LOW: Re: New member - question on 'half' alive Model 100 The NiCad only powers the RAM when there is no other power source available. When you have AA's installed or a power adapter plugged in then that is what is powering the memory, even when the power switch is off. My first tests were done with the NiCad removed but AA's installed so the RAM was always powered. It was rather inconvenient though thus I installed the temporary battery and lifted one leg of the diode so it would not be trying to charge the lithium battery. I did try a CTRL-BRK + reset several times with no apparent difference in results. Just to make sure I'm not misunderstanding this key sequence it is the CTRL key in the low left, BRK on top row of function keys and the reset button on the back?
