  1. I got an original Atari 5200 box when I bought some Commodore stuff, the guy was storing a couple of 1541 drives in it. It's not perfect, but it's in decent shape for its age I would say. I have no use for it, happy to give it away free to anyone in the Atlanta area that wants it. PM me if you are interested.
  2. Mainly because I'd prefer to build one rather than buying one whole. Practice my soldering skills, etc.
  3. Anyone have an extra FinalGROM99 pcb that they'd be willing to sell? I want to build one up but the ones on eBay are a little pricey after shipping. I'd also be interested in ordering a new batch to be printed if there is enough interest.
  4. Hi all, first post, first TI-99/4A. Just won a silver and black TI-99/4A with an lovely Alps keyboard off of eBay for $30, including the power cord and joysticks, which I think was a fair deal. I didn't even bother testing the machine when I got it, as I didn't have a video cable at that point. A few scuffs on the aluminum top, but hey what do you expect for an almost 40 year old machine. I disassembled the machine and found the biggest issue right away, which was that the RF shielding was extremely rusty, which left rust stains on the ground plane edges of the mainboard, and rust stains on the bottom of the case. I scrubbed the mainboard edges with IPA and small squares of 3M green pads, and used Barkeeper's Friend powder on the inside of the case (tip from a boating board for cleaning the inside of coolers, lol). I washed the mainboard, power supply board and keyboard with dish soap and water, which cleaned up a treat. The boards honestly look brand new. I was going to retrobrite the keys to get the lettering whiter, but I was afraid it would dull the black and they look great otherwise. I went ahead and put the machine back together without the shielding, and once I got a cable, fired it up. Holy moly, it works! My question is, what do I do with the RF shielding? I'd like to put them back in to keep the machine original, but I've soaked them in a phosphoric acid rust remover to clean them up which has removed what's left of the plating. Does anyone know a good cheap plating shop that will accept and ship parts by mail? All the chrome shops around here focus on automobile restoration and are both expensive and don't like bothering with small jobs. Should I just toss them? Sam
