Philip, I have studied the documentation on your work on your 3b1 emulator project. I am trying to rebuild a bootloader for a Convergent Technologies MightyFrame, and I have several working UNIX PCs that I am using for study, since they are similar...(by no means identical, but similar enough). You seem to have done some fantastic work on I see your posts on comp.sys.3b1 from 3+ years ago, and I am very impressed with your ability to decode the design of the UNIX PCs bootloader file. I was wondering if I could request some help with doing the same for our MightyFrame bootloader. I'd love to chat. I've sent a few emails to the address you provide on your 3b1 emulator site, as well as responded to your 3-year-old comp.sys.3b1 thread. Congratulations on some fantastic work, and I look forward to connecting with you.
