As far as I know converting a Compaq Prolinea 4/33 to use a Compact Flash card should be easy, although I want to make sure what I'm doing is correct.
The Compaq Prolinea 4/33 is an interesting system, as mine is from June 1993 and it has built in IDE\Floppy\Serial\Parallel\Graphics (Tseng ET4000), as well as built in PS/2 ports. It has 4 72 pin SIMM slots, 3x 16-bit ISA slots on a riser card. It has a single 5.25" drive bay (occupied by 1.2 MB 5.25" floppy), a external 3.5" drive bay (occupied by 1.44 MB 3.5" floppy) and an internal 3.5" drive bay for a hard drive.
As for my 1st question, I want to replace the hard drive with a Compact Flash card. This here should be simple, just add a IDE to Compact Flash adapter and a CF card. Make sure the BIOS can recognize it and have fun. The adapter I found is here, a IDE to CF adapter that replaces a expansion slot blanking plate for easy removal.
Going off of the Compact Flash conversion, I will need a Compact Flash card. I don't know what all will work. The only card I have right now that isn't a 4 MB or 32 MB card is a 512 MB Lexar "Platinum" 40X card. I have no idea if this will work, I can't find anything about it on the internet. From this, does anyone know of a card that can be acquired for around $5 or less that will work, and be anywhere from 256 MB-2 GB (FAT16 partition size limit).
As for the final question, upgrading the original 33 MHz 486 DX to a 66 MHz 486 DX2. As far as I know the DX2 will run on the same config as a 66 MHz 486 DX, as it uses the same bus speed and voltage with a internal 2x multiplier for the 66 MHz. I myself have a computer with a 66 MHz Intel 486 DX2 that I can try as long as I don't risk completely burning up my processor and\or computer.
