it was a weird experience that now got an explanation
according to wikipedia "An abundant number which is not a semiperfect number is called a weird number" perhaps that also applies to experiences :) I am bemused by quasiperfect numbers... "An abundant number with abundance 1 is called a quasiperfect number, although none have yet been found"

Huh, and I thought a day was 24 hours .. Oh well :)

The children of a relative in the UK are being taught Abundant Numbers and mum is having a tough time keeping up. The theories are almost 2000 years old. I understand how to work out the various (numerous) derivatives but what worldly purpose do they serve?? I have lived many years without requiring any abundance (other than a paycheck) It seems almost as crazy as the Common Core Math they teach here in the USA. Anyway, I would like to understand the importance/use of Abundant Numbers.

depends on your budget. I bought a few EP2C5T144C8N mini boards through Amazon for under $20 each but you would also need the $10 'Blaster' programming cable. Look up "RioRand EP2C5T144 Altera Cyclone II FPGA Mini Development Board " on Amazon.(free shipping) just connect to 5 volts. The Software is free from Altera (now Intel) I use Altera Quartus II 13 sp1 I have several 8 bit microprocessor emulator projects I run in them

Using a computer with insufficient resources. A few years ago (more than I care to remember) I was developing a hardware graphics processing module using FPGA's. I had what I considered the final iteration and wanted to run one last round of simulation for the entire design. Just after lunch (1:00pm), I set up the simulator for 30 seconds of real-time processing (1500 frames) and started the run. At 6:00pm it was still processing (phew!) so I left everything running and went home. The next morning (7:00am) it was still running but around 9:00am the software reported the simulation was complete, so I clicked the [Continue] button and the computer then took another 2 hours post processing files until it finally generated an "Insufficient Memory" error message, deleted all the results and terminated the program. I had 32Gb of memory installed (was 8Gb) and the repeat simulation took just over 1 hour... (my original expectation) All that for a 30 second simulation. BTW the design was successful.

Next question: How many plants does it take to produce a ton of oxygen a day? Obviously, a huge pine tree will produce more than, say, a tomato plant. I guess that plants will have to double as both oxygen and food sources; there wouldn't be room of huge forests within that plastic bubble. Do food plants vary a lot in their oxygen prodction capabilities? With Mars being roughly speaking at 1.5 times the Earth's distance from the sun, solar radiation is at 40-45% of Earth levels; I guess that could affect the photosynthesis.
with the use of solar energy collectors and artificial lighting, Earth-like levels can be replicated or increased. but will the 'soil' support terrestrial vegetation ?.

PCMCIA was the organization that defined the interface (Personal Computer Memory Card International Association). The interface became better known as PC Card. you can find PC Card readers on Amazon and there is a useful set of links on the Wiki page https://en.wikipedia.org/wiki/PC\_Card

They should release the data into a group of enthusiasts like ours. With a co-operative effort I reckon it will be decoded
