I am cleaning out my workshop and have a number of items I no longer want. Please make any reasonable offer (and some of this stuff a reasonable offer is like a beer or something) and come and get them. I prefer pickup in Augusta, Georgia (about halfway between Columbia, SC and Atlanta, GA) as they are all heavy. Neo-Geo Arcade Cabinet Gutted, no monitor, but includes all buttons and joysticks, a 2-slot motherboard and a universal power supply. No game carts, and I don't know if the motherboard or power supply works. I live on a hill, so bring a strong friend or two and a truck. Nintendo-style Phoenix Cocktail Arcade Cabinet This has a 13" monitor and a Phoenix game board. It worked years ago, I don't think it does anymore. All the hardware is there. I live on a hill, so bring a strong friend or two and a truck. Arcade Boards This is a plastic bin full of old arcade boards. Some work, some used to work, and some never did. You gamble or I will split them up. Pac-Man Plus Mortal Kombat Punch-Out Galaga Kung-Fu Master Nintendo Vs. Route 16 Phoenix Others I can't identify. ColecoVision Adam Expansion Module This is the version that needs the ColecoVision, but I don't have a spare CV for it. I has the printer and a tape or two, it powers on but just gets a black screen. Coleco Adam Standalone System Comes with printer and a tape or two, it works fine with carts, and loads tapes "sometimes". I don't know if the tape drive needs service or it's something more. X-Arcade Dual Joystick Works fine, hardly used X-Arcade Tankstick with TrakBall Never used, still in the box. X-Arcade Dual Joystick Complete housing/case only, no electronics, joysticks, or buttons. Nice project.

I've tried to piece together time periods for childhood memories, too. It's tough and your memory plays tricks on you. There is a lab loaner of Ms. Pac-Man as late as 9/20/83, if that means anything. I think 1982 is wrong, probably. http://www.atariprotos.com/2600/software/mspacman/mspacproto.htm Also, the catalog says expected delivery was February, 1983. For sure it was probably released a little later than that. http://www.atariage.com/catalog_page.html?CatalogID=57&currentPage=6

A7800x is based on the mess a7800 emulation and as was pointed out earlier it does not work under mess. Is it because it's accessing the POKEY at a non-standard address instead of like a real POKEY cart?

Unfortunately this doesn't run on a7800x (original XBOX 7800 emulator). The screen turns green and it makes an awful racket. If I run the bin and turn off POKEY support, it runs, but silently.

Yes, the power supplies are identical. To swap between the original 12v sound chip (SID) and the newer 9V SID only requires that you change a diode inside the unit and a couple of capacitors (if you want- it affects the filters).

Already own it, already hooked up. The reason I use the ADAM over the Colecovision is because it has composite out which is nice. The few ADAM exclusive games aren't worth it otherwise. Tempest Yeah, but how do you get sound out of it that way? There is no audio output... Pete

I can't believe this is even a remotely difficult decision to make. 100 or less games vs. 10,000? The public decided this in 1983.

Try turning down the brightness knob in the back.

I'd use my 600XL in a heartbeat since it's basically NIB, but it doesn't have a monitor port and there's no way I'm going back to using RF. Tempest the _Majority_ of 600XL motherboards have the ability to add a monitor socket easily (you just need a monitor port and a selection of resistors and capacitors - Or Best Electronics sells a kit for about $12.00). Take a look here http://orph.atarinet.com/photos/main.php?g2_itemId=4413 I've done this to Three 600XL's I would buy this kit from them to upgrade one of my 600XL's, but I can't find it on their website. That site is about the worst thing I've ever tried to navigate since the mid 1990's. Link?

They were always super-popular at "copy parties" here in the U.S.

Not necessarily- some chips send all 3 region codes, some send only one. Most of them send all three.

I've repaired a lot of those over the years and I can't recall a defective SX power supply or RAM failure, which are very common on the regular desktop models. Surprising (from Commodore) but they seem very rugged. For whatever reason, usually the PLA and one or more of the ROM chips are the fault on the SX. You've swapped the PLA with a known good one (retest to be sure) so try swapping ROMs. The kernal is the most common failure, and can be swapped for the C64 ROM, you'll just get the blue colors instead of green/black SX. Watch the pin alignment, as it's a 28-pin on the SX and only 24 on the standard C64. Other than that you can make sure that the boards are seated together 100%- it's a 90 degree pin/socket setup from the mainboard to the power/drive boards and that being loose can cause your symptom as well. Push on the board on the right-hand side until you can't see the pins to make sure it's tight. Good luck!

You answered your own question!

Probably not at the same time, safely. The original C64 supply is 1.5A on the +5V, and 1A for each leg of the 9VAC. The 128 has 2.5A on the +5, but still only 1A for each of the 9VAC. I wouldn't try it due the AC draw. I'm not positive how much current the C64 draws on the 9VAC lines, but I'm sure it's not half the rating.

An interactive game would not fit even in 128 kbytes... I pondered this way long ago, but I immediately quit it ! Yes, but the RAM problem had been solved later in the life of the 2600. Sara, CBS RAM+, etc.

Isn't there something odd about the CoCo artifacting where the colors are reversed sometimes? I seem to remember something about "restart the computer until the colors are right" on some games... Seems like Blue and Orange are reversed occasionally.

The C64 is *the* gaming machine for the early-to-mid 80's (and up to the 90's outside the USA).

Yes, it does that in other emulators as well. I just use Altirra now and no problems at all. It's a nicer emulator, and still updated.

OK, I give up. What does it mean?

Some of the games are really amazing for this system even with the limited hardware. There is a game that is like "House of the Dead" (13 Ghosts?) with parallax scrolling and everything. Really amazing what some people did back then!

It takes a lot of work, but new cap kits and complete solder reflows will fix most problems like this with the Vectrex.

Battlezone had a "mathbox" (bitslicer) add-on to calculate the 3-D effect. I would imagine that would slow you way down...

Really nice hack. My only comment is that the Ms. Pac-Man "siren" sounds more like the sound that regular "Pac-Man" should play during the power-pellet timeout.

Somebody mentioned the lack of a Harmony cart for the 7800, but with a little electronics experience, you can make your own SRAM cart that works with the DevOS. Does anyone make these carts for people one-off? I've made the simple 32k version, but would like the bigger bank-switched one.

Probably too high starting price, but I can understand not bothering to sell it if you can't get what it's worth "to you". My general rule is that if it only sells for what I would pay for it again, then I won't bother.
