There are at least 2, and they are totally #different. I was given an IBM IEEE488 card which uses a pair of 9914 #chips (one for data transfer, one to send commands, I think). The one in #the O&A Techref is based round a NEC 7210 chip. The information I received from Brain Boxes is that their card uses the NEC 7210 chip. They still have some of these cards in stock, although they are no longer in production. They sent me a very helpful e-mail. The only problem is that they want 320 pounds for one card. Well, I don't know what things cost in Britain, but out-of-production DOS-based ISA cards generally don't sell for US $540. Usually, it is more like US $5, maybe new US $50. So, I don't think I will be doing any business with Brain Boxes. Louis
