Again when the IBM PC was new, laying out an ISA board was a frightening activity. You in all probability didn’t have a really quick ‘scope, in the event you had one in any respect. Board structure was virtually definitely carried out on a drafting desk with massive items of tape. It was laborious for small corporations, a lot much less hobbyists, to make a brand new card. You possibly can purchase a prototype board and wirewrap or in any other case put collectively one thing, however that was additionally not for the faint of coronary heart. However with trendy instruments, one thing like that may be a very doable challenge and [profdc9] has, actually, carried out it. The cardboard makes use of an ATMega328P and offers two SD playing cards to be used as mass storage on an outdated pc.
The design tries to make use of components that gained’t be laborious to get sooner or later. No less than for some time, but. There’s capability for growth, too, as there’s an interface for a Wiznet 5500 Ethernet adapter.
Are you able to think about in the event you may transport this card again to the times when the ISA bus was what you had? Simply having a pc quick sufficient to govern the bus would have been sorcery in these days.
We don’t know in the event you want an ISA mass storage card, however in the event you do, [profdc9] has you coated. Then once more, you do have choices. Or, in the event you’d fairly take a deep dive into the expertise, we can assist there, too.
