H.A.R.P for MC68000 CPU accelerator board
H.A.R.P for mc68000 was manufactured and sold by Jast Inc from 1994 and is accelerator board for X68000. This is a replacement board for the X68000 Built-in CPU and it is intended to be plugged into the CPU socket to increase processing speed. It is compatible with first generation models (except those that have soldered in CPUs) up to SUPER.
There are red in the center dip switch SW1 on the basis of the photo, if you normally use, at any one time under the 2 (OFF) If it is OK to. SW1 when used with Memory Co., Ltd. - It is said that just made to ON 1.
☆ ☆ ☆ Oh! ☆ ☆ ☆ X Information H.A.R.P will be doubled to 20MHz internal clock of the CPU, 2x accelerator. But the body remains at 10MHz from the street now, I needed it to arbitration. That is, when calculated in the CPU is even moving into full-20MHZ, when accessing the external bus is considerably 落Tosane do not have to 10MHz. Therefore, the actual rate of say what happens, “We have only about 10% faster!” Is that it is not.
