I want an emulator that the front panel's look is very similar to the original as the picture below. Below are two screen capture of the emuStudio-039. It is a Java program. I want an emulator which I can click to input the command, just exactly like what it done with the true MIT Altair 8800. Altair 8800 front panel. Source
What additional hardware was required for BASIC on an Altair 8800?
2020年5月4日 · I remember being aware of the Altair 8800 when it made it's mark, but only vaguely. Lately I found myself wondering what hardware was required for the Altair to get BASIC up and running. According to Wikipedia the original 4K BASIC was distributed on cassette and paper tape, so it seems reasonable to expect the user to have one of these ...
How did Altair 8800 interrupts work? - Retrocomputing Stack …
2023年8月1日 · I'm playing around with building an Altair 8800 emulator in my free time in C#. I've read through the Operator's Manual many times in the past, and I'm refreshing my memory of late. I'm struggling to understand exactly how interrupts work. So, presumably, some kind of signal from outside the machine is capable of triggering an interrupt.
How was the Microsoft PDP-10 8080 emulator developed?
2017年10月21日 · From your link that appears to be what happened. They weren't sure it would work until they ran it on an actual Altair 8800. A comment in the source code, "FOR SIMULATOR FIXUPS", suggests that it was conditionally assembled according to whether it would be run on the emulator not, making the code for the emulator and the Altair different.
Why is the original Altair BASIC (for the 8080 CPU) source code …
2019年7月26日 · As described by The Register in 2001, around 1987 journalists and others started asking Bill Gates for a copy of the source code for the original version of Altair (eventually Micro-Soft) BASIC, written for the Altair 8800 and other 8080-based machines. This turned out to be fruitless, but a paper copy eventually was discovered at Harvard and ...
Test emulated 8080 CPU without an OS? - Retrocomputing Stack …
2019年3月15日 · I have implemented this protocol in a testbench for an FPGA Intel 8080 implementation inspired by a software emulator test suite; both of these could be useful references for you in implementing the scaffolding necessary to run these CPU tests without any complicated OS, or even any computer, around your CPU.

Single-stepping the Altair 8800 - Retrocomputing Stack Exchange
From the Altair 8800 Theory of Operation Manual & Schematics 1975: The Single Step circuit consists of a dual single shot (IC M) for debounce and the SGL STP flip-flop (R-S type). When the machine is in a stopped mode, depressing the SS switch will set the SGL STP flip-flop.
Source code of front-panel entered Altair 8800 programs
I'm looking for the source code of short programs for the MITS Altair 8800 (let's say < 50 instructions to make the question more specific), so they can be entered by using only the front panel....
Fixing obscure 8080 emulator bug? - Retrocomputing Stack …
2019年6月4日 · Though instead of a hexadecimal address your emulator printed 78=:. In other words, it would seem your 8080 emulator is failing on the code to convert a binary value to hexadecimal in ASCII. Which is the BYTEO routine and in particular BYT02 which converts the bottom 4 bits of A register into an ASCII character.
