Now begins a new adventure, this one I'm taking my time on. The last system I built took about 7 months and it's still not done so I expect this to take me a while.

What I have so far:

Baby AT Mainboard, M915I or 80486VIP haven't yet confirmed which

It seems to have LBA with a 8GB limit, it's odd because the BIOS only has primary master/slave yet the board list secondary, looking at the traces most run to the 'primary' and it makes me wonder if the two onboard IDE ports are actually master/slave and meant to look like 'dual channel'- I'll have to test this out.

Intel P24D 80486 DX2 66Mhz, HSF appears to be epoxied to CPU
2x 4MB , 1x8MB FP SIMM MEMORY

DIY PC D480W-W-RGB ATX Mid Tower Case, 2x 5.25" Bays

Sound Blaster 16 CT2910 ISA

S3 Trio64V+ 4MB PCI Graphics card

On order/waiting for it to arrive:

QD6500A 2.0 Vesa Local Bus multi IO controller.
1x 64K x 8 BIT SRAM DIP-32 + 8x 128K x 8 SRAM DIP-32

Due to limited space I am not sure how to address floppy, I would like a 5.25" but that means I need a expensive dual floppy to fit in this case with a CD rom.

I'm looking for inspiration, ideas and tips.

No L2 cache?

1x 64K x 8 BIT SRAM DIP-32 + 8x 128K x 8 SRAM DIP-32

On order from China, 2-12 weeks 😜
This board did not have fake cache, just none and the BIOS chip is socketed. Better than some of the versions of this board.

Made some progress today,
I was hoping to use a IDE to MicroSD card but I can't seem to get it to boot, FC1306T is the listed chip with a small flash, but doesn't seem to be bootable.
Did manage to benchmark it, format the drive Fdisk etc.. all appear to work just not booting (partition is active)
