Actually no. This strongly suggests 64K ROMs. However, it does not rule out a 512K RAM upgrade. The only way to determine that is by visual inspection or using software 2.0 to 4.1 (it definitely will not run on anything above 4.1 with 64K ROMs).Thanks for the great reply! I clicked the interrupt button while the system disk was loaded and a window popped up saying "Sorry, a system error occured" and "ID=13" with a Restart button highlighted and a highlighted Resume button. So this means its been upgraded correct?
