Just curious, can Sega Master System ROMs be played on a Game Gear? Not that it would matter, since there's not music software for SMS either, but just curious since I seem to remember SMS emulators also being able to run Game Gear ROMs.

I believe they can, by cutting the jumper between pin 42 and ground. I have placed this jumper on my own cart, but it is hard to see because of the tSTOP layer over it. This jumper is the larger white circle at the bottom right.

I agree. Ive been thinking about playing non nintendo handheld music lately.

I can only imagine a world in wich I can play with my neogeo pocket...

Find someone to write the software, and I will make the flash cart. Done deal.

I have literally put in over a 100 hours into Eagle this past month and want to do more than just one board printing per month!

This is a 512Kbyte cartridge but could support up to 1MegaByte if I can find a decently available ROM chip. Also, OSHPArk needs to offer more board thickness options. I can't have them print this because they only do 1.6mm boards and I need a 1mm board.

I pre ordered both and have been waiting for a very long time for the next non-sequel, reimagining.

I think I prefer to have my artist's mark inside the battery cover. That seems like a nice place.

I agree. When I sign the gameboys I mod, I sign on the inside. It would seem too show-offy to do it elsewhere.

How much bass did you think the gameboy had? Go ahead and post clips.

I would be into these boards like crazy. Would want to order two, FYI smile

Very happy to hear that! They should be right around the same price of the GB programmer boards too, unpopulated of course.

Then we can have a z80 competition between all of the purchasers to see who can do the coolest things with it!

I think it would show up the very best on the transparent shells.

Yeah, thanks Kitsch. I have looked into the acrylic boxes before because I think they look absolutely perfect for the indie-type of builds. I can't say that we would need a top half, or at least not yet considering the fact that this is stackable. If we were to assume a maximum of three stories (CPU level, serial/usb/video/keyboard level, and a perfboard level) then we could make a whole enclosure I suppose.

As for the size of run, I was going to aim for 10 boards again. We may have to look into half-shells for the GB programmers. They ended up being heavy to one side because of the cart connector, meaning stand-offs don't help a whole lot. Room to learn I suppose.

Anyhow, keep talking to me people! Start thinking about whether you want a colored PCB, ENIG, or if I should do kit-bundles again. Obviously, many parts are obsolete and harder to source, so kits would only include everything minus CPU/RAM/ROM. A pre-soldered kit would have sockets ready to drop your chips in. Then again, I do have a large handful of 27c64's so maybe a pre-programmed BASIC ROM option too.

Finishing up the main tracing and still positioning silk screens stuff. The board is not going to be just square as it is shown, so I may design a bottom half of a housing shell in CATIA. I know nothing about how we can get plastic objects printed though, so if anyone knows, tell me. Here is the basic chip placement:


Resistors will be made Surface Mount to save space and so the ground pour doesn't get chopped up so much. At this point, there are many free headers on either side of the board. Ceramic Caps will remain through-hole so that VCC may be routed on both sides more easily and to offer more coverage of GND.  um...yep. That is all for now.

I like the cycle, but feel like it is missing a sprite on both sides of the "still" sprite. One where he bends his knees to absorb the landing and prepare for the next leap would make it seem more smooth.

Sorry, I was at work so I couldn't really reply to people.

@Alpine, I am familiar with and attached to Jazzmarazz, so you have a point, although I wouldn't say "A lot of stuff" under it. tongue
Im still just an unknown face on the web.

@rygD, You also have a point, I should come up with it myself but I am having difficulty. I don't want something Super serious, but nothing along the lines of Super-duper-make-cool-stuff Co. either.  lol

As for the board, the bare simple version is coming along well. I have located an ideal regulator in a lovely SOT-233 package, but the thing holding me back seems to be that I have to create a lot of the libraries myself, or modify ones that I already have. The good thing about both drawing a schematic and board layout is that I may choose the packages and parts myself. No one can tell me to go with parts I do not wish to use.

Next I will be changing up the quartz crystal to a larger quartz oscillator in the 014 or 008 package so that users may alter the rate more easily. If I can locate a highly available variable clock IC, I may utilize that but we'll see what happens. After I find these things, I can move on to tracing the rest of the board and then creating a blank "shield" with loads of tie points.

I will be confidant to share photos in a day or two.

EDIT: Got rid of the parallel resonance altogether! DERRR! Why was I messing with a two pin clock at all?!

Obsolesense. Sense of the obsolete.

I think I shall start with a bare z80, rom/ram setup. Nothing special, but fully moddable. It will cost much less and can be made to do anything, even as much as the full computer I hope to make soon afterward.

I like this approach.  Even a little perfboard on one side to make additional jumper/headers to solder to would be nice.
As far as the moniker, I'm a little surprised you would ask for advice.  Those types of things are always so personal.
It usually will just click, anyway thanks for all of the effort.

The board so far has USB (power only) and regulated DC input with a Jumper to select between one or the other. So far, that is all I have added aside from the cpu/rom/ram.

I do like it, but it leaves me in the same place. I would like to move away from Jazz altogether. It is the past-me and has no relevance with my goals.
