Proprietary toolchains of that era are a special beast. They are probably talking about proprietary compilers and development tools, which were certified and depended in win98 environments. Perhaps they just ran the toolchain in a win98 qemu instance and developed on a modern computer. That is what I would do and I am an embedded build system guy.

I’ve had problems emulating serial/parallel ports using qemu and usb. I had a legacy system that had some external devices. We just ran it on a hunk of junk on the sneakernet

  If i recall correctly you can pass through USB ports if needed. Also given that serial/parallel ports are very simple you can often just write a driver or use the super powerful socat to massage things if needed. I once used socat to serve autopilot simulators that spawned on socat's socket accept and piped to actual serials. I could then serve serial over the networks. Really if I was a poet i would write an ode to socat Anyway, peripherals were non the wiser on the nature of the piping. A bit of annoying plumbing but can be done and enables you to have scalable CIs for embedded devices.

  Why would a DSP assembler need access to a parallel port? Anyway, it probably works fine in Wine, more reliably than on native w98.
