PC and compatibles
General PC hardware, shared expansion buses, specific vintage models, and modern compatible systems.
Expansion buses
ISA, Micro Channel, EISA, and PCI boards for PC-compatible systems.
| Computer, compatible system, platform, or interface | Introduced | Products |
|---|---|---|
| EISA expansion boards Extended ISA expansion boards for EISA systems. EISA slots can accept many ISA cards, but EISA cards require the extended connector and an EISA host. | 1988 | 0 |
| ISA expansion boards ISA expansion boards for PC systems, including original 8-bit PC/XT cards and later 16-bit AT cards. Check each listing for bus width and software requirements. | 1981 | 18 |
| Micro Channel expansion boards Micro Channel expansion boards for IBM PS/2 and other MCA systems. MCA is electrically and mechanically distinct from ISA and EISA. | 1987 | 1 |
| PCI expansion boards PCI expansion boards for PC-compatible desktop systems; check voltage, slot, firmware, driver, and operating-system requirements for each card. | 1992 | 1 |
General hardware
Drives, input devices, and other upgrades using shared PC interfaces rather than one expansion-card bus or exact IBM model.
| Computer, compatible system, platform, or interface | Introduced | Products |
|---|---|---|
| General PC hardware Upgrades for PC systems that use shared drive, keyboard, serial, parallel, display, or other interfaces rather than one expansion-card bus or exact IBM model. | 1981 | 19 |
IBM-specific systems
Upgrades whose evidence names a particular IBM PC model.
| Computer, compatible system, platform, or interface | Introduced | Products |
|---|---|---|
| IBM Personal Computer 5150 The original IBM PC with 8-bit ISA expansion slots and external floppy-oriented storage. | 1981 | 11 |
| IBM Personal Computer XT 5160 IBM's hard-disk-equipped PC successor with eight 8-bit ISA expansion slots. | 1983 | 14 |
| IBM PS/2 Model 30 286 IBM's 10 MHz 80286 desktop with VGA, 16-bit ISA expansion, and a 1.44 MB 3.5-inch floppy drive. | 1988 | 1 |
PC-compatible systems
Non-IBM PC-compatible computers, modern recreations, and their model-specific hardware.
| Computer, compatible system, platform, or interface | Introduced | Products |
|---|---|---|
| Compaq Portable III Compaq's 12 MHz 80286 portable PC, offered with an optional two-slot 8/16-bit expansion unit. | 1987 | 1 |
| ITX-Llama A Mini-ITX x86 system designed for late DOS and early Windows 98 software, with integrated period-style audio and modern storage and networking. | - | 4 |
| Micro 8088 A compact modular IBM PC/XT-compatible computer built around an 8088 or NEC V20 processor board and an 8-bit ISA backplane. | - | 7 |
