Sellam: I certainly would be interested. And, if the interface is "easy" enough I can integrate software support into the Altair32 Emulator.

It connects to a PC parallel port and is driven through software. It can be updated hundreds of times a second, which for all intents and purposes will seem continuous. We're going to write simple software drivers to control the board. It's simple enough to be integrated into just about any PC-based emulator and is designed to be scalable (up or down). Would there be any other interest in purchasing this controller? Board fab and parts in quantity 5 has the price at about $100 right now (unassembled). If there's enough interest then I'll manufacture a large batch to bring the price down and sell off kits to recoup the design and manufacturing costs for myself. E-mail me if you're interested. -- Sellam Ismail Vintage Computer Festival ---------------------------------------------------------------------------- -- International Man of Intrigue and Danger http://www.vintage.org [ Old computing resources for business || Buy/Sell/Trade Vintage Computers ] [ and academia at www.VintageTech.com || at http://marketplace.vintage.org ]
