oh, all right, the ASP story. ASP was an early IBM "multi-processor" ca.
1975. ASP = Attached Support Processor.
Here is my memory of it.
They connected (at my site) 2 370/158s via a channel (the magtape channel
interface was the final low-level data path, of course). The attached
processor saw a "virtual card reader" and the main processor submitted
jobs via that channel to the ASP. At that point, of course, the ASP had
its own tape drives and printers. This was allegedly easier to admin that
two separate machines.
Virtual card readers ... via magtape channels ...
Now *that's* a kludge.
Although V5 if memory serves did something similar, I guess, I never saw
this but I did find a manual set once with a jcl(1) command.
Actually, there has been progress.
