My 2 cents worth.....
Here is a list of items I need to make my trusty 2000/3000 and 4000 productive again. Number one being the most important, and down to the least.
1. Affordable network cards. I can't buy 10 meg cards at 100+us$ per card for 3-4 machines. I need a reasonable 100meg card for some thing less than $50us
2. New Accelerator Cards. PPC is fine but maybe that new coldfire project would be an economical choice too. I don't see the need to put in an intel in a classic to run UAE. I can do that on any pc clone. Maybe a coldfire version of OS4 could be released.
3. New keyboards to replace the crummy original commodore ones, again that don't cost a fortune.
4. Graphics upgrade. An ATI card on Zorro III or an IDE expansion bus would be nice.
5. Sound. My old AD516 cards are still great, but I could stand an update to the DAC features for recording and special effects.
In honesty, I don't think you can make much on any of these projects. With A1 and pegasos boards becoming more available, you would have to come in with a really decent price for me to concider diverting funds from and A1 to my classics. But if you could, I would definitly buy at the right price.
Good luck!
