Industry Standard Architecture (ISA) is the 16-bit internal bus of IBM PC/AT and similar computers based on the Intel 80286 and its immediate successors during the 1980s. The bus was (largely) backward compatible with the 8-bit bus of the 8088 -based IBM PC, including the IBM PC/XT as well as IBM PC compatibles.

2022年1月19日 · Since the last decades we have seen several 32bits ISA standards appear. Some of them like RISC-V, MIPS or Power are now even open-source. Is there such a standard for 8bits ISA? I have feel that 8bit CPUs are completely abandoned in favor of 32bit today.

2024年9月26日 · ISA 8-bit Backplane 是一个紧凑的 8 位 ISA 总线背板，设计用于构建 IBM PC/XT 兼容系统。 该项目由 skiselev 开发，旨在提供一个更小的 Micro ATX ISA 背板版本，适用于使用 Micro 8088 处理器板和 8 位 ISA 卡的系统。

ISA 8-Bit Ethernet Controller is an open source network interface controller (NIC) card, designed specifically to be used in computers with 8-bit only ISA (aka XT) bus, such as IBM* PC, IBM* PC XT, various PC/XT compatibles, for example Micro 8088 system. It is based on Realtek RTL8019 ethernet controller and is NE2000-compatible.

2019年7月21日 · This project is to create a simple 8-BIT ISA I/O board for use with classic IBM PC/XT/AT systems for the purpose of experimenting with creating of BIOS Extension ROMS. The design includes a GAL16V8 chip for decoding the I/O address and eight LEDs that show the status of the 8-bit register.

Compact ISA 8-bit Backplane board. This backplane was designed as a smaller version of Micro ATX ISA Backplane. It can be used to build a compact IBM PC/XT compatible system using the Micro 8088 processor board, and the 8-bit ISA cards that I've designed: ISA Super VGA, ISA Floppy Disk and Serial Controller, XT-CF-Lite, ISA OPL2.

2016年2月13日 · It is called XTMax and it combines the functionality of three ISA cards: 1) Conventional memory any amount up to 640 KB with zero wait states and fully supports DMA so it can be used with physical floppy and hard drive controllers. 2) 4 MB of Expanded RAM using an updated LoTech EMM driver.

2024年11月17日 · XTMax is a software-defined 8-bit ISA card which uses a Teesny 4.1 microcontroller board that provides the functionality of THREE vintage ISA cards. It can expand "conventional" motherboard RAM up to 640 KB, adds 4 MB of Expanded RAM, and provides hard-drive access using a MicroSD card.
