AST Research

Before AST became one of the largest PC-compatible manufacturers in the world, they were making graphics cards for IBM's PC range (PC, XT and AT).



Graphics Cards

AST-3G Model 1

The AST-3G Model 1 was AST's third-generation graphics card. It supported MDA, CGA and EGA. Click here for the user manual from March 1986.


AST-3G Plus (1986)

Part Number: 202104-001

The AST-3G Plus was another of AST's third-generation graphics card. It suppo

rted up to the EGA standard. It was based on the Chips & Technologies CS8420 chipset, and had 256 KB of onboard video memory.

It came with one 9-pin EGA D-SUB port, two RCA video outputs, a lightpen socket, and a parallel port which required a cable to be connected to one of the headers on the board.

There was an option chip that also allowed backward compatibility for Hercules and CGA.


AST-3G Plus II (1987)

Another EGA card from AST.



Another VGA card from AST.


Launched: 1987
Part Number: 202262-001
Memory: 256 KB
Bus: 16-bit ISA
Chipset: Paradise PVGA-1A

Processor Boards

AST HotShot/286

Part Number: 202160-001

The HotShot/286 was a CPU upgrade board for the IBM PC or PC/XT computer. It contained an Intel 80286-10 CPU and cache memory.


AST Xformer/286 (1987)

Part Number:

This motherboard was designed as a direct swap for PC and XT-class computers, and came with an Intel 80286 running at 10 MHz, and 512 KB of RAM (expandable up to 1 MB). Expansion Slots were four 16-bit ISA, and four 8-bit ISA.

It came with a utility diskette that allowed you to configure the card. You would simply run 'ASTUTE' from the floppy disk. The CPU speed could be switched from 6, 8 or 10 MHz using Ctrl-Alt-Up and Ctrl-Alt-Down, all at zero wait states.



AST 386 Daughterboard

Part Number: 202347-002

Don't be fooled by this one - it's not a CPU upgrade card like Intel's InBoard 386/PC or 386/AT. Its actually the main daughterboard in the AST Premium 386 desktop computer range. For the Premium 386 launched in 1989, AST attempted to innovate the internal layout of a desktop PC, by having a mainboard which consisted almost entirely of just the usual ISA expansion slots, but two of these slots had a proprietary extension into which would be installed this "386 CPU" daughterboard. On the daughterboard was a 386DX CPU running at either 25 or 33 MHz, 387 coprocessor, and main memory via four SIMM slots. The second ISA slot that also had this proprietary extension could be used for other AST cards, such as a FastRAM memory expansion card.


AST 486 Daughterboard

Part Number: 202397-003

As above, but is a 486.
