Have been wanting to build a tiny 486 for a while now , I will be using a with a passive 3 slot ISA riser and putting all of my big box towers away in storage.
Can you share some photos of your plans? I have a 386 ISA SBC and don't know what to do with it. I don't have any 386 computers, so if it can be worked into a small machine, it would become something useful to me.
Nothing as grand as plans yet - the general.idea will be to use a 3 slot ISA riser as the backplane, with the SBC, a network card (for networking and XTIDE rom) and an ESS 1868F sound card.
So the overall size of the system will be just over 3 slots high and not much longer than the length of a 16 bit ISA slot.
Will probably use a spare pico-psu for power and a CF adapter for storage - no floppy.
Not sure of case yet - I have 3d printing facilities, but I'm no 3d artist. It will probably come down to a small enclosure from RS or Mouser, or maybe dust off my creaky old woodworking skills and fabricate something myself.
Think perhaps 50% shoebox size. That's the aim. The card I have on the way is almost identical in size and layout to the one you posted. I love the size of these things.
