I got this socket 3 motherboard

ZIDA 4dps

It is a beauty. i never had a small compact board with PCI and ISA, it also accepts amd x5 133 i belive, and only takes FPM ram.

I have not tested it yet, but upon examination i did find some things broken, and i need advice on what those parts are in order to buy replacements.

this is the full board

these 2 are the broken components:

From what i understant the first one is a ceramic capacitor
Capacitor (472)
4700 pF
[4.7 nF]

The other one is a diode, somehow it has a broken leg, and maybe broken in the inside too,
but i have no clue on what diode i need to replace it with.

can anyone help?

thanks guys

i replaced the diode. the board had the fpm 8meg memory on upper slot. did not boot
changed memory to down slot and booted bunch of times

then changed to 16mb fpm memory and did not want to boot. tried like 30 times and did not boot nor gave video signal
even changing to the original memory and it did not post.

another lottery boot motherboard?

after hours i was able to boot using a 4mb fpm stick

should i replace all caps? its strange that it did not post,not even with the original memory that worked

Check for cold or cracked solder points as well. I'd replace that one tantalum (tantrum) cap by the ISA slot, if I were you.

i was able to get it up and running nicely
the problem was the memory

the board is only compatible with FPM memory ,but even using that memory is a lottery
because i got a bunch of FPM 16mb memory with chips on one side and it refused to boot

but using FPM memory with chips on both sides i was able to reach a total of 32mb
very nice board
