Just as an FYI, I also got the core TI-74 ROMs and sent them to another person to get a TI-74 emulator done. As everyone here probably knows, the CC-40 and TI-74 are almost identical internally. So, we have two folks working on emulators... one for the CC-40 and one for the TI-74. The TI-95 (this third very closely related one out of this trio) has already been emulated: http://www.rskey.org/CMS/index.php/the-library/13 - roms http://www.hrastprogrammer.com - emulator

Probably saw some on eBay way back when I wrote this post.

Nope. Worked fine with the light switch. Outlet was deader than a doornail when light was on via the switch. Used a meter on it with a TV plugged into the outlet (with the light off), and was only getting a fraction of the voltage - 60-80V once the TV was trying to draw the current. (Dad wondered what the heck I was doing, since I was only 8. I did manage to shock myself on another couple occasions, but I learned really quickly what to do and not to do. i.e. 1 - Don't remove a resistor from a neon light. It was there for a reason. and 2 - When thinking you have the neutral leg of a outlet, verify with the ground to make double sure. <grin>)

Is it a brief dim or a dim the whole time the 128D and CRT was on? If it's just when you turn it on, that's not a big deal, that's called "inrush current". Many appliances do that. In fact, even some circuit breakers are rated above their 15A/20A for so many milliseconds for this very reason (AC kicking on, humidifier kicking on, etc.) If it's a long term dim, yeah, I'd get your wiring checked out. Probably not related, but here's a good example of strange crap happening: When I was probably 8 or so, my family lived in a rental house for about six months that had an outlet that didn't work in a bedroom. When you plugged something into it, the more power it tried to draw, the brighter the ceiling light in the room would get. Whatever you plugged in wouldn't work, either. That was probably a fire waiting to happen.

I really have to get mine working properly. PG4UW is supposedly looking for the EEPROM in a certain offset in the 1284P, and the actual data in the other part... so it's either I'm not programming it properly, or is the #!#$% PLCC ROM socket....

Yep, four daughters here. Gonna be fun when they're all teenagers in a few years.

Woot... look what I'm burning right now on a W27E040 :-) ... and the three titles (BlackJack and Poker, Hopper, and Blasto) now all work properly. Thanks, Gazoo.

I own at least three ways to save with a CC-40... (currently transitioning to someone else, but still...) You just couldn't get them from TI. https://www.youtube.com/watch?v=e5YLiarJjnk https://www.youtube.com/watch?v=bpC5MIVlvz8

Thanks to quite a few people helping, everything we have related to CC-40 ROMs has been dumped so that MESS emulation work can commence. The last part, the CC-40 32K BIOS (bank switched) has been dumped. With that... I present to the community, every existing CC-40 cartridge binary + the 32K BIOS + 2K on-CPU ROM. https://dl.dropboxusercontent.com/u/19597743/ti-99-4a/CC-40%20DUMPS.zip Hap is working on the emulation in MESS. Ksarul helped with lending an ear (during a very long phone conversation). JGardner from the Vintage Computing forum helped with giving me the correct assembly to force a bank switch (and then copy to a 32K SRAM) to enable the ROM to be dumped. Lee, who just sold his entire CC-40 collection, also gave me some ROMs to compare against. Enjoy, everyone. Let's hope Hap gets us a good CC-40 emulator going here soon

.

Yep, Ksarul and I discussed it extensively one night. We have some pretty cool ideas for sidecar boards.

I'm fine with the board tools, Sometimes... but what I'm looking for is another thread where we can put things that I point a lot of people here for; stuff like the Multicart topics, etc. Newbies need a starting point

Could we sticky a thread up at top? I'd like to see if we could round up all the following in a thread that we can update (but not really use for discussion). 1) RXB Updates 2) 512K Cartridge status link 3) Gazoo's EPROM images 4) Tursi's Multicart image 5) Rasmus' projects and images 6) Other project updates (Alex Kidd, etc) I'm just tired of going back and forth trying to find EPROM images in search, and for the 512K Cart, when I point people to AA, they can see the sticky, click it, and it has a link to the thread. Same with the multicast images that Gazoo and Tursi made. Anyone having time and want to take a shot at it? Thanks!

This guy is smoking something... http://www.ebay.com/itm/360931923444

You know you've been watching a certain TV show when you see the word "artifact" and start thinking something like this: hehe

That is correct. The 74LS379 only banked up to four lines, so 16K/32k/64K/128K. The 74LS378 is a newer development that is can bank six data lines. 16K/32K/64K/128K/256K/512K. It has not seen wide release yet and is only starting to gain limited release into the community. If anything, we can probably be safe to extend the MESS TI emulation to support this new bank switch method (which is easy peasy compared to the reverse banking that was the 379 banking.) The 1M cartridge is really a 512K cartridge with a switch on it control whether the TI sees the high 512K of the 1M EPROM or the low 512K of the 1M EPROM. It probably would not make sense to support unless Ksarul or myself build a cartridge with a 74LS377, which can support up to 2M of bank switching. (But also needs 20 pins for the 377 vs 16 for the 378, and a 27C160, which is probably not supported by a lot of programmers, since it's 42 or 44 pins, and most of the less expensive ones top out at 40.)

Yeah, I swap 9V batteries in the detectors once a year, but the old ones are still good. So, I wind up with a surplus. The golden Hakko hemisphere is indeed a tip cleaner. :-)

Heh... well, it's actually a Hakko. It's visible in the way back of my workbench. I'm still using the nice ASD mat that InsaneMultitasker gave me a long time ago

I have a trick for this. Do you know that black ASD foam that chips come seated in? I simply put that over the headers to keep them in place while I flip the board. I then solder one from each jumper header, flip it back over, take off the foam, straighten if needed, and then solder the other one. I only have to solder the other one or two ones separately that aren't part of that cluster. And no, the solder gun doesn't melt the foam for some reason :-)

Hey Gazoo, here's another one. Attached is the 32K EPROM (copy to 32K) as well as the raw >A000, >C000, and >E000 code. arcturus.zip

Just as a FYI (sorry to resurrect this old topic); I found the guy responsible for this game's graphic design. http://sloperama.com/business/prodlist.htm I was searching for info about my old Chase N Counter LCD game and came across his website. E.T. And His Adventures On Land TI-99/4A Graphic designer

Heh.. I think that'll be our next thing to tackle (jumpers). Otherwise, I'll be buying stock in bulk purchases of jumpers on eBay like this: http://www.ebay.com/itm/1000-PCS-2-54mm-Standard-Circuit-Board-Jumper-Cap-Shunts-Short-Circuit-Cap-/291138609395?pt=LH_DefaultDomain_0&hash=item43c936a0f3 :-) :-)

Nice work!! That reminds me of when I had to do the 128Kx4 because of the 74LS379 usage (before Ksarul suggested looking at the 378, which I didn't know existed at the time.) It's amazing how this little cart board has evolved since I started. I'm truly impressed at everyone's effort!

AFAIK, no CRU control or any other way to control what roms go with which GROMs unless both ROM/GROM programs are patched with new ROM banks locations. We wanted to keep the design simple. :-)
