+nanochess Posted May 14, 2018 Share Posted May 14, 2018 Hi. After some testing I think the TMS9918 chip in my first TI-99/4A is fried. I would like to replace it, but I see that eBay only has Chinese suppliers for the VDP chip. Experiences? Someone has eBay vendor suggestions?

+acadiel Posted May 14, 2018 Share Posted May 14, 2018 I have one somewhere from when I installed my F18. Let me see if I can find it. It might take me a little bit to find, but if someone else finds one first, that's ok. Sent from my moto x4 using Tapatalk 1 Quote Link to comment Share on other sites More sharing options...
atrax27407 Posted May 14, 2018 Share Posted May 14, 2018 I have one from a working console. It has a bit of heat sink compound on it but AFAIK it is in working condition. PM me with your mailing address and I'll get it mailed. How does $10 sound? You can send the $$ via PayPal if it works satisfactorily when it arrives. 1 Quote Link to comment Share on other sites More sharing options...
