Just got myself an A3000... need some help! :D

[mechy]

ah cool, ok, so CIA's are linked to keyboard control. good. i wasn't sure. i'll give them a swap and see what happens.

that's good info regarding the memory, vesalia website seems to show that they have some km51440az zips in stock in packs of 4. ordered 8 packs, and an indivisionECS, and 3.1roms, but haven't recieved an order confirmation email yet....

aaanyway, lets swap those CIAs

thought. if i put a 5pin din to ps2 adapter on the A3000, can i use the A4000's keyboard?

---update---
swapped the CIA's nothing's changed. managed to break a leg on pin 9 by being a little bit ham fisted. :grr: but wedged a piece of wire in there to make the connection.

The typical 5 pin to ps2 adapter works and will allow the use of a 4000 keyboard.
if you cant find zips, i do stock the 1mx4 at http://www.a4000t.com

To answer some earlier question.. the 3000 must have the backplane to boot. this is normal.

cool, i'll see if i can find a keyboard adapter. sure i have one somewhere...

sorry, yes, i did mean the daughter board, and yes i do get a yellow flashy screen without it ok good, so that's normal. right. learning lots today.

ok, battery damage. taken a photo of it, and it looks much worse properly lit with a camera flash than under the energy saving bulb in the bedroom

i've tickled it with some vinager, and some cotton buds, is that going to be enought to stop it?

Mechy, thanks for the zips offer, i'll give you a shout if i get stuck otherwise

---update---

tried a 5pin to ps2 keyboard adapter. brand new adapter, the bag not even been opened. plugged it, plus a known good A4k keyboard into the 3000. she wouldn't boot.
so unplugged, let the machine boot to workbench, then plugged in the adapter and keyboard. screen went grey and no drive activity. unplugged and she rebooted.

upshot is, i've found a way to reboot without switching off and back on again... and we now know it's something on the mainboard that's not happy.

I wonder of +5v is missing on the keyboard port?

ok, after double, and triple checking which pin supplies 5v, i got out my trusty multimeter... wait, no i didn't - i couldn't find it, so stripped the wires on a tiny PC fan and stuck the ends in the keyboard port holes and switched 'er on!

no movement. nothing. ... phew... in a twisted way.

spliced a wire from a drive power header to the 5v supply pin on the port. woohoo! all is working! both with the A3k and A4k keyboards!

now just a case of making something more permanent.


now, the battery corrosion. so i should be good with it like that? so need to put something on it to stop further oxidizing?

thanks again all

Good deal.. i would fix the fuse right in that +5v circuit if you can,since if it ever gets shorted again it may take out a trace without it

On the traces he is right-open copper will oxidize, i was going to suggest it,but i wanted to be sure there were traces left after cleaning before telling you to coat it lol.
