I could supply parts, but not until the current orders and promises have been met...
For the power supplies, you can buy your own from where I get them. You may want to get a higher wattage 7.5v supply, like 150 or 200W if you are retrofitting an altair with a ton of memory cards. I never had a problem with mine when I had ~6 8k cards in it, each with 32 ram chips.
Look here for the power supplies
