—Dear Sirs,
Where can I find information on what hardware can be used to upgrade my old AST Advantage! Adventure 4066d?–Also referred as the “All-in-One” model as it’s monitor is housed in the case as everything else is, also. There is an empty footprint for another cpu on the motherboard and the one that is there is an 486dx2-66mhz. I want to purchase better memory cards, a graphics card and a hard-drive. The added processor it can have is what I want also, want to fix it up nice as a novelty item but want it to have maximum performance, also!

Stick MS-DOS 6.22 on that and you will have a fast PC……….
And you don’t need the 487 co-processor, because the DX2 has an x87 FPU built in.
-Since it’s an all-in-one unit, you can’t upgrade the graphics card.
-Unless you add an ISA or VLB IDE (or SCSI) controller, the BIOS will only recognize hard drives up to 540MB.
-If the motherboard uses 30-pin SIMMS, then 32MB is the maximum amount of RAM you can use (8x4MB). If it uses 72-pin SIMMs, up to 64-128MB, depending on how many slots it has and if the board has any soldered RAM.
-If it has an empty COAST slot, adding an L2 cache module will really speed things up, especially under Windows 95 or NT.
The empty socket is for a 487 math co-processor.
