Okay, so I'd like to start to tinker with programming a little in ASM and a little in Basic on my dear ol' Genesis - I've had a bit of experience with both languages, so I don't think that's going to be the hard part. The hard part is that I would like to be able to actually test stuff out on my Genesis, and would like to do so without any soldering or other modifications to it (as it's the only one I have and I like to fire up Gunstar Heroes every now and then.) So I know that I have the option of some sort of EEPROM/flash cartridge, but I'm a little too broke to afford a new one. (College and the American Way - keeping kids in poverty for the rest of their lives!) So I'm wondering if there are any plans online for the construction of a test cart or possibly something to utilize the serial port on the back of the Genesis, to possibly send it instructions when it's started with no cartridge in (a la Gameboy Advance). Any help I could get here would be VERY much appreciated.
Oh, and a place to get cheap EEPROM chips and writers would be nice too.

My friend, it has already been done, eproms, genesis serial cable - just go roam around. Actually, it is all there in my genesis section on my website. There is a schematic for building an eprom cart (for flash, you just gotta change some of the pins), and there is a serial uploader that uses the player 2 port to transfer programs to ram. For eprom programmers, there are a couple of programmers you can build from radio shack parts out there. A nice place for inexpensive parts is ebay too =). Also, you don't really need to get into eproms or hardware just for developing on your sega, you can also use an emulator.
If you have a sega cd, or if you can find one at the goodwill, you can also visit mask of destiney's site. I dunno the url on the top of my head, just go to google, serch for "sega cd development", and you're there. With his tools, you can burn homegrew programs easily, and transfer programs from the serial port too. He also has 68k assembly tutorials there too

Ah, silly me, I must have glossed over the parts of your website with the links, I'll look again. I have actually heard of the SegaCD development options, but as I have no Sega CD system, I can't take advantage of it yet. I only WISH I could find one at a Goodwill here - I have yet to come across one, and that's not for lack of trying. Found a TurboGrafx, tho, but that's another story for another board. ANYWAYS. Will a model 2 Sega CD work on a model 1 Genesis, or do I have to seek out the bulky, rare, tray-loading monster to get any play from my system?

Genesis and Sega CD are cross-compatible.

nono the sega cd and the base unit are totally different systems, totally different architectures. code built for the slave cpu's hardware cannot be used on the master cpu and vice-versa

The Model 2 Sega-CD Will work with the Model 1 Genesis. When the Model 2 came out it had a "Base Extender" which was just a piece of plastic that clipped on to the side of the Sega-CD that would make it as wide as the Model 1 Genesis.
I never liked the Model 2 Sega-CD.. it just looked.. cheap.

i never liked anything model 2 i have a model 2 genesis, and all the parts are all surface mount, no pdips or anything, and the video on it is too intense, i mean light-wise, and you can see (or is it just me?) the verticle lines that seperate the cells.

the model 2 also has a solder resistant layer, which makes mods a little harder, and that model can't be overclocked =P. the upside: it's smaller =D, i made another little sega genesis computer using the model 2, and a wooden case that looks like an apple 2 for a friend
