Bzzt, wrong. The rev c KDF11-A was the only 18 bit CPU in the 23s, despite DEC propaganda of the time. ( "No, you have to pay $$$$ for a 23+ for that... ") You will also have to chuck any 18-bit memory or controlers if you want more than 128KW. Note, 128, not 124. You can have all 128KW in a Qbus. ~Paul
