Hi, I was lucky to buy a very nice operator panel of an old IBM S/360 model 30. I am now trying to rebuild this IBM S/360 model 30 (using this panel as a base) with modern TTL, EEPROM's IC's etc. With the current information I have, I was able to reconstruct about 50-60% of it's logic diagrams. I am still searching for ANY customer engineering documentation of this old IBM system, specially the small CE reference booklet for the model 30 and the Functional Maintenance Manual. Anyone who can help me ??? I already have a copy of the 'Theory of Operations' and micro-code flowcharts manual. Regards, Henk Stegeman, IBM collector Phone: ++31-70-303 4513
