Same for circuit boards. I was told at one time there was a set of tools that would do the layout and the whole mess that everyone shared. At least for some of the oddball stuff you see for the PC, such as the 3270 adapters, being the most conspicuous. There are others that have technology you'd see if you opened a mainframe of the 43xx or so variety, and it looked an awful lot like the 3270 pc cards did. But others clearly were done with the same technology, and were not mainframe gizmos. (can't recall example at the moment though). I know from the work I did in the last three years that IBM probably had embraced outside tools much more now rather than using their own owned tool sets. I don't have direct evidence, just an impression. If you feel like sharing the part, by the way, my buddy would appreciate it if it is for a model 30. Likely could be for a model 60 or 50 just as well though. thanks Jim
