IBM Vintage Mainframe Computer with Options (9370 or AS400)
Were not positive its a 9370 but a reliable source told us he thinks it is...
Includes the following options -
QS90 p/n: 12F7729
Two 6310 p/n: 46F3385
Or... this may be a communications buss that goes between an old AS/400 and other devices, like modems.
