Re: [cosmacelf] Re: Flash memeory
- As I was wondering through my Jameco Catalog, I found a good deal on Flash Memory chip for $5.95 so I bought two to give may ELF XXL a total of 1 mega byte memory,I am planning on bank addressing in 64K byte blocks, with Bank 0000 mapped to the normal 1802 memory space, and Bank FFFF mapped to a separate/partitioned video memory space.
5 VOLT 512KX8 DIP-32 90 NANOSECONDS FLASH, see attached datasheet
I would like to start developing my schematics, is the Eagle Hobbyist the cheapest available??

IP/ethernet certainly isn't one of them. It's only "simple" in the sense
that you can dump your wallet on the table to buy some off-the-shelf
board with software to do it all for you.
All you really need is a simple serial port between them, and a little
software. I've networked Parallax BASIC Stamps this way, and they are
even dumber and slower than 1802's. :-)
