My thanks to the group for providing useful input in response to a poorly defined question.
I had broken my problem statement into three parts. 1. what I wanted to accomplish 2. a view of possible solution 3. thoughts on what hardware might satisfy needs/desires/aesthetics
Unfortunately my original post pureed all into amorphous glob. My apologies.
I'll break things down in above groupings.
1. What am I looking for It might be described as "data logger" or a "very large FIFO".
The input will be an RS232 data stream terminated by <CR><LF> of no more than 100 bytes at 4800 BAUD occurring once per second.
It shall buffer/store at least 10 mega bytes
The output shall be via USB 1. I wish to take advantage of USB speed 2. My computer has available USB port(s) 3. My computer does *not* have available serial port(s)
2. Possible solutions
Flash devices are large and do not require power to maintain data.
There are environments such as FORTH which can presume any mass storage device/system to be a sequence of nnn byte blocks/sectors/whatever
3. available hardware
Let's just forget how badly I mangled this one ;{
Is this a better problem definition? .
