This will help us to know if we are running faster or slower then a real system under simulation on various hardware and OS platforms. I added the comments to paraphrase the surrounding text in the "E" IMS PDF. I too wonder how they got the numbers, but I didn't want to make any substantive changes to the code. I hope so too. Not many systems were 21MX-E, but as I recall, GMU was and it was reported that it was quite noticeably faster. Just for the record SIMH does too, it now has all of the peripherals required to run Access. You should take it for a spin, just explode the ZIP on a Windoz box and run Access.bat and you should get the "MAG TAPE SELECT CODE?" questions. (Its 16 for the zip) The disk images in the ZIP are pre-loaded with a system, just select the 2883 loader and answer the questions in the dialog to do a disk boot and your up. You can telnet to your box and log in. It's a good quick way to take "E" or "F" for a spin too; we have separate ZIPs for each. My recollection is that the 7900 is 2.5 Meg words or 5 Meg bytes, and that the 7905 is 7.5 Meg words or 15 Meg bytes, feel free to offer information to the contrary. As for the real equipment you may have surplus, count me in! I have 2 racks, several tape drives, a paper tape reader, and an MX that I have not powered up. I also have the hard to find stuff like micro-code, MUX, interconnect kit, bootstrap tapes and MCP tapes. I would rather have the racks with the step, 2100 CPUs, and a couple of 7900s, but beggars can't be choosers. I would not turn down a 7906 but I would have to find a controller. I would also need to find tape controllers and some of the cables. Keep us posted, Mike.
