[cctalk] Any Burroughs B5000/A Series NEWP programmers out there?

Hey, Did any of you do NEWP programming on Burroughs/Unisys A Series systems? I will be attempting to put together some presentation material (for VCF or similar talks) on MCP internals programming. However I haven’t done it since 1989, so am looking for others who have experience in this area to help me remember details. I took the MCP internals class and still have the class exercises and my notes. Recently a A12/A15 Hardware Operations manual popped up on eBay. I scanned it and submitted the scan to bitsavers. I am hoping to get my hands back on some system architecture documents that I once had. So, if anyone here worked on this stuff and wants to help out on this, let me know. alan
