MC68030 based expandable computer design
The specification for MAXI030, a MC68030 based computer, is as follows:
A core "glue" that is wired to master the 32 bit busses Glue is provided by an EPF10K130EQC240-1 FPGA A 68030 coupled with a 68882 512K x 16 flashes in the form of 2 x SST39SF040 in PLCC32 2 x 72 pin SIMM slots with a controller implemented in the FPGA A SC26C94 QUART with the following arrangements of the four serial ports: Two on RJ45 at RS-232 levels following the standard Cisco pinnout One for my Amiga 600 keyboard on an RJ11 And a TTL header for debug and the bring-up Onboard 10Mbit/s Ethernet using a RTL8019AS A…
