Here goes my (vain) attempt to build an entire 8088 (an x86 ancestor) computer out of breadboards, wires, and more wires! The first picture is the breadboarded system. Top is the Intel 8088 clone (NEC V20) because it can operate at lower voltages and a 50% duty cycle clocking, which I can get it from other microcontrollers. The middle has the latches to hold the address, and the buffers to control the data in/outs. On the right is the extra circuitries for selecting which RAM/ROM to access. (address decoders) The bottom is the SRAM (Static RAM) which is only at 512kilobytes. Trust me, it's a lot back then. I have not connected the EEPROM (Electrically Erasable Programmable ROM) yet - this is the part where the BIOS firmware is stored inside. [After all, this is what this website is all about!] The other picture is the EEPROM programmer I whipped out because I'm too lazy to buy them from Ebay. As the name goes, it programs the firmware inside. The challenging part is to write the BIOS firmware using assembler, and to carefully connect this EEPROM back into the circuit after programming. As there is no "graphics card" or anything, I have to manually program the interrupts (INT 10H here) to send the output to a small character LCD. Once it's done I can do a memory test and maybe add more stuff to it. It may take many weekends since I can only work on that for these time!
