FDS DRAM chips available for sale/trade

I found some LH2833-15 DRAM chips for the FDS RAM adapter.

If anyone wants/needs one, let me know.

I have no idea what the pinout for this is, or even if it can be replaced with SRAM. (Probably not easily because I think the address lines are multiplexed like most DRAM).

BTW, if you're looking for really cheap RS232, check this out:

The voltage levels are already 5V, so no extra parts.

I don't know if it's as reliable or fast as the FTDI stuff, but it looks cheap enough to try.

I thought about this before. Was going to put the PPU on an ISA card, and put it in the fastest cpu/motherboard I could find with ISA.

Timing might be an issue, unless you clock the CPU at some multiple that the PPU has to run at. (Correct me if I'm wrong about that).

Damn, I'd like to go but the drive from California is a little long, and I'm not very keen on flying these days.

Did Super Mario All-Stars use the exact same code?
Or did they port all the bugs too?

I've written some 6502 assembly, but man, it is tedious. I haven't tried tackling a big program yet, but plan to eventually. I do a lot of AVR programming in C and I think it has spoiled me. Maybe I haven't written enough assembly to write it fast enough. I've heard of people writing assembly code a...

I liked the music and the extra animation frames. Gameplay is kinda ok, nothing special.

Hate to say it, but this is probably the reason I got into NESDev in the first place (wanted to play FF3 in english on a real NES). I did most of the research myself, and didn't ask anyone anything.

Reading a serial stream using an AVR - advice requested

So here's what I want to do: Read a serial stream using an AVR (ATMega8) (serial stream protocol details here): http://www.guysoflidar.com/files/v1_protocol.pdf I'm quite familiar with the AVR, just never had to write a software serial decoder before... Would you suggest I use the device's hardware ...

Game design 101 - questions

So I'm working on an Arkanoid clone (with powerups, enemies, etc) as a programming practice project. Using XNA/C# to do it (because I know C# and dot net). What is a good method to detect which side of the block the ball hit (either X or Y) to reflect the balls corresponding velocity (either X or Y)...
