A retro-style computer that functions like the Altair 8800 and can run original, unmodified software. It ran on the MITS Altair 8800 and subsequent S-100 bus computers. Allen wrote those two crucial pieces. To make sure I was doing things in a controlled way and to eliminate other variables, I downloaded your patched version of CP/M 2.2 1.6 (HDCPM22v16-63K-1024.DSK), renamed it HDSK06.DSK on my SD card, powered on the Altair, mounted it, booted with HD boot ROM, and then loaded/ran your BASIC program below.Same results. The Altair 8800 simulator is part of the SIMH family of simulators currently at version 3.8-1. Unlike a real Altair 8800 it features several enhancements: Choice of processor (8080 CPU, Z80 CPU or 8086 CPU) Optional banked memory (16 banks with 64 Kbyte) I knew this was my chance to finally build an Altair 8800!
