I have two AST Bravo computers.
A Bravo Advantage 486/33
and A Bravo 486/33
These where the first generation of Multimedia computer for the consumer made by AST.
The basic model came with
Intel 486dx2-33 CPU
8kb cache
4mb ram
2x Sony CDROM drive
Media Vision PAS16 Sound card.
Onboard video
I really like the look of the case but these computers are not easy to upgrade.
The motherboard is small and strange. Not a standard size motherboard.
I could not find any cache that would work with these motherboard.
I was able to find the manual online with jumper settings.
to use a different CPU you need to change the BUS speed to 25mhz for 486-25 or 486-50 or 486-75 CPU.
For a 486-33 you need to use 33mhz BUS speed. For a 486-33, 486-66, 486-100
Also AMD CPU's are not supported but I was able to get one to work also and also Cyrix CPU.
in the Over drive socket.
Here are my AST LC Bravo builds
1) AST Bravo 486/33
AST Bravo LC2 4/33s (486) Multimedia computer ( 1993 )
2) AST Bravo Advantage 486/33
Also I had to replace the Sony 2x CDROM drives because the drive capacitors leaked all over the circuit boards and basically destroyed them.
These AST computers are not that good. because they are hard to find compatible parts for and the CDROM drives used cheap capacitors.
Also the BIOS is not to good and the CMOS Coin Battery is soldered to motherboard.
