The 8080 processor emulation was designed from the ground up to be as accurate as possible. The emulated CPU duplicates the performance of the 2Mhz 8080 in the Altair 8800. Emulation is performed at the memory cycle level. Every LED on the front panel is …

Software designed to run on a typical Altair 8800 will run on the clone in the same manner and at the same speed as on the original Altair. The Altair 8800 Clone accurately duplicates the operation of an Altair 8800 equipped as follows: CPU – 8080 running at 2 MHz. RAM – 64K of RAM with memory protect in 256 byte blocks.

The 8080 provides the programmer with an 8-bitac­ cumulator and six additional 8-bit"scratchpad" registers. Register pair PSW (Program Status Word) refers to register A (7) and a special byte which reflects the current status of the machine flags. This byte is described in detail in Chapter 2. MEMORY The 8080 can be used with read only memory ...

Does the emulated 8080 CPU really duplicate operation of a real 8080? The 8080 CPU emulation in the Altair Clone passes a tough set of CPU tests . Some of these tests exercise undocumented "features" and quirks of the 8080 CPU that can only be tested by comparison to real silicon.

The Altair Clone provides three floppy “drives” that duplicate the function-ality of the original Altair 8 inch floppy drives or the Altair Minidisk 5.25 inch drive. Floppy storage is implemented using non-volatile RAM inside the Altair Clone. Since physical …

Mar 21, 2022 · Note the butterscotch brown chip to the left of the 8080. Its a Bulgarian 8224 clone. I could not find a reasonable source for a genuine Intel chip, so took my chances on this item and got a couple of them for $1.69 apiece.
