Needed to wait for Lattice Semi to send the hobbyist license file

FOUND ONLINE COMMENTS THAT SUGGEST FORMATTING OF MAC IS AN ISSUE

Some internet messages suggested that Lattice expects the MAC address of the network interface to be formatted a specific way, without hyphens or colons as most systems display them. My first request changed the subject line to Renewal from their boilerplate New iCEcube2 License Request wording. I then changed it to what they had, since they may have a simple script grabbing the license requests. 

When I still had radio silence for a long period, I did some searches to see if others were experiencing delays or other problems. That is where I found hints that they expect the MAC to be 12 contiguous hex digits although their boilerplate simply asks "MAC address for license generation: " without any format guidance. I sent off a third request just now, hopefully matching the unspoken rules and allowing me to receive the license file shortly.

RESPONSE RECEIVED - LOG ON AND REQUEST LICENSE FILE

I was given a subscription number as the response to my earlier email requests. That had me log onto the Lattice website and request a license for the subscription. With that number entered plus my MAC address without hyphens or spaces, it told me to wait for an email. 

Great news, however, because the license file arrived almost immediately. I set up the program to point at the license and was able to synthesize and create the bitmap which I have to flash onto the FPGA memory device so that the new logic becomes active. 

SUBSTANTIAL PROGRESS DOCUMENTING BUILD OF V2315CF

It is a complex project that requires building and then modifying George Wiley's RK-05 Emulator, building several custom PCBs, modifying the internal disk drive of the IBM 1130, making wiring changes in the 1130, connecting quite a few units together and then installing them in a custom enclosure or inside the 1130 system. 

There is also the need to create Solid Logic Technology (SLT) compatible male and female connectors since we are intercepting signals that run between the disk drive and the 1130. Mini 2315 cartridge replicas are constructed to hold the contents of the virtual disk cartridges, and software is used to manage theses mini cartridges. 

I have generated many images to help guide the builder in these steps, then written about each step with those pictures in support. I had to cross reference many schematics and design files to be able to clearly identify where wires are connected or removed. 

I estimate that the document is now 75% complete. A few more days work and I should be able to upload it to the github repository.
