Hello eyerone,
I wonder if there's currently an x86 emulator around that..
- emulates an 8086 or V30 or 80186 or 80286 CPU
- an corresponding x87 FPU
- emulates glass terminal, CGA or Hercules or Hercules InColor
- emulates an EMS board, EMS-capable chipset or synthetic EMS hardware
- does not limit base memory to 640KiB, ie. lets the user select
the total amount of contiguous memory up to ~1MiB
The latter is mainly an artificial limit caused by the EGA/VGA framebuffer technology of the day.
If only Hercules is installed, 704KiB can be available. If only CGA is installed, 736KiB can be available (just checked).
If no video system is installed (terminaly via CTTY only). ~900KiB can be available.

Anyway, I'm just curious. It would help me making experiments in
which I could find out how to optimize by one and only PC/XT clone..
Any comments and suggestions heartly welcome.
Best regards,
