[Coco] CoCo 3 512K memory upgrade

[Paul Shoemaker]

Good evening everyone,
Does anyone know whether Cloud-9 is still selling the Triad 512K SRAM Upgrade?  I am wanting to upgrade the memory on my 128K CoCo 3.  I previously emailed them at orders at cloud9tech.com  inquiring about several products, but I never received a reply.   If for some reason Cloud-9 is on hiatus, is there another source for a 512K memory upgrade?
Appreciate the help!
