WangEmu 1.1 released

I've updated my Wang 2200 emulator to version 1.1. It has been about six months since the last update. This release adds two signficant features: 1) disk support. You can now plug in disk controllers, each of which can control two drives. Drives can be any legal size, and the timing can model that of 5.25" or 8" floppies, or hard disks (even the interleave factor is modelled). You can optionally turn of the emulated timing and make it run as fast as possible. 2) when an error message is displayed on the screen (which are just two digit codes), double click on that line and a detailed explanation will pop up. the explanations come directly from the Wang BASIC manual. Adding the first feature was a lot of work. I started with the microcode dump from the disk controller and a document describing the microarchitecture (believe it or not, the 2200 has a 4b ALU and the disk controller has an 8B ALU). From there, I wrote a disassembler and studied the listing until I thought I understood the protocol. I implemented it and ironed the wrinkles out of my assumptions. Please have a look if you are interested.
