I have two Computer Logics PCTD-III Pertec 8-bit ISA interface boards available. I have no software or docs to go with them, though I should have at least one cable set. From what I can gather from past discussions of these cards (h/t Chuck G.), they require driver-supplied firmware. They've been on the shelf the entire 19 years I've been with my company. Cards are offered as-is, $20 + shipping for the pair. Shipping via USPS or FedEx, your choice.
