I put 1100 0011 0000 0000 0000 0000 in the 2764 eprom --- this is supposed to test the z80 -- I have a 555 timer running at 500 khz. Can this small program work with the z80 ? I looked at the address pins on a m465 oscilloscope. The address shows highs up to 0100 0000. I think it should only count to 0000 0000 0000 0011. Can the z80 be tested? The Santa Clara Valley also made the lm1871 radio control chip that could not show a high or a low without completing the entire rc loop.

I'm trying to remeove the first 8 bytes from binary file using the command:
dd if=new.pdf of=new2.pdf ibs=1 skip=8
but it's taking too long.
Is there a way to remove the first 8 bytes, in a faster way ?
ibs=1 is requesting dd to read one single byte at a time. It's going to be slow - for each byte, there is a context switch to the kernel.
I would:
tail -c+9 new.pdf > new2.pdf
I think you could use dd, choose the best block size for your specific environment, and... skip the bytes:
dd if=new.pdf of=new2.pdf bs=4M iflag=skip_bytes skip=8

What is the number permission for o+t
It has to be close to 1755 but that's not right.
Using chmod o+t mydir. I get drwxrwsr-t
Using chmod 1755 mydir. I get d-wx-ws--t
I want to know what the number permissions are for o+t
It is simple to find that out:
touch test
chmod 0000 test
chmod o+t test
stat test
... gives you: 1000 (octal)

I have a project that is using a 125Khz RFID cards,dots, stickers.
I need a card reader that has a read length of AT LEAST 4-7 metres.
The reader will collect all tags within that range and check them against an inventory.
I have not been able to find any RFID readers that have this range, and I am not sure if it is at all technically possible.
Does anyone know if this is technically possible with a 125khz RFID?
According to wikipedia http://en.wikipedia.org/wiki/Radio-frequency_identification the maximum range for 120–150 kHz (LF) is 10cm.
