A stock Amiga 2000HD has a 209X SCSI controller I think, no memory. Your computer should have a 1 meg Agnus with 1 meg chip mem, no fast. Add an accelerator with a bit of memory on it and you have something. I use an old GVP Combo 030/40 with controller on it. good all around machine, compatible. To run newer Versions you must have a minimum amount of memory, usually 2 meg or so of fast, the more the better.
