Re: [neonixie-l] Re: My NixiChron is sick, what do I do?

2016-05-15 Thread Instrument Resources of America 
In my 50 years or so of worinkg on electronic equipment, I have 
quite often seen Vcc and Gnd, and others very often omitted from 
schematic diagrams, to help eliminate clutter. Quite often a separate 
page or diagram will then be used to show various, power and ground 
distributions. This is almost always the case on high density circuit 
boards.Ira.

You can have a look at the schematic of the NixiSat (which was posted here earlier - not

Interestingly, at least in that schematic, it looks like the VCC and GND (pin 
16 and 15) of the MAX232A are not connected. It could just be a shortcoming of 
the schematic of course (in fact, I would be a bit surprised it worked at all 
without them - though it's not completely impossible if e.g. it's powered 
through any internal voltage protection diodes), but you may want to double 
check this on the actual PCB. The other IC's in the circuit do show their 
VCC/GND connected, so it's a bit surprising to see it missing from just the 
MAX232A.

I don't know. And because I don't know, I didn't want to post the whole 
thing. I have worked with a variety of possibly-proprietary information 
over the years, in both professional and hobbyist roles. Unless I have a 
record of receiving the information with the understanding I could 
redistribute it, or unless I know it is an archived copy of something 
previously published, I won't redistribute it. In this case, I posted an 
excerpt which was sufficient to answer the question posed (the serial path 
between the CPU and the HV drivers).

Jeff told me that the clocks were a collaborative design, with Jeff doing 
the hardware and packaging designs and the assembly and someone else doing 
the firmware, which Jeff paid a per-piece royalty for. So there is likely 
someone who still has a financial interest in the design.

Speaking of which, I'd be interested in getting an updated CPU with the 
latest US DST tables. I purchased an upgrade from Jeff way-back-when, but 
it still doesn't change at the correct dates. I believe the person who did 
the firmware posts here occasionally. If there are some other people 
interested, it might be worthwhile to see what a batch of new CPUs would 
cost.
