Fixing my Milan 040 (or not) blog

[exxos]

If you had a spare 060

Nope, but thanks, wasn't aware of that project

So a single beep sounds positive. Looking at the source, the next thing the bootblock does is try and initialise the keyboard, which is on the SuperIO chip so I suspect it might be stuck waiting for that to respond (which is difficult if it is removed ).

Quite possible Whoever updated the stuff must have never thought that chips will be missing from the motherboard

Good it booted with the original stuff though! I might have given up otherwise!

So BB104 is test_20060514.zip I dismissed it before as it said TEST 104 doesn't work either.

But next I need to fix a broken track, gunk up the solder resist I scraped off. Possibly replace the vertical simm socket.. much to do yet

Repairing the track I cut while diagnosing the problem .

Put on a gentle simmer until I remember to turn it off or the battery goes flat...

Will go on a hunt for SIMM sockets now..

The "wrong" vertical simm socket..

Thought I better clean out my solder station before starting another job!

Outwith the old.. Hopefully those damaged vias are not important!

Looks like 11 & 12.. 11 is NC and 12 is A0 But its pad and track on the bottom seems fine. So "not important" at this point in time..

In with the new 45° socket... Which will no doubt set of some people's OCD ! but I'm not changing the other three SIMM sockets I cannot be bothered

Need to find a new battery.. New PCI socket (ordered from aliexpress just ).


Probably not much else I can do until my replacement chip comes now

I do need to figure out how to actually connect a keyboard to this thing at some point though! And how the hell do you connect a mouse even ?!

Also does anyone know what form factor this motherboard is, is it a mini-ATX ? Will need to find the smallest case possible to fit it all in at some point as well..

EDIT:
Maybe a cheap case like this would do ...

This might be available online but I have the paper manual in German.

The DIN socket is the keyboard, you can use a DIN to PS2 adapter.

The mouse connects to an 8 pin connector just next to the pci slots. There should be a short internal connection cable.

I can't see any mention of the form factor but I think it is full size AT.

[exxos]

It must be designed to use one of these...

Probably had one years ago, brand new and chucked it away at some point

Can only seem to find them in the USA

[peters]

I actually drilled a hole in the back panel and got rid of the slot plate.

[exxos]

Looks like it will cost about £30 to get a bracket with PS2 connector and cable cannot even find them on Ali express.

Anyway, I have asked my UK broker for a price on the MC68040RC40 mask L88M.. They only deal with genuine parts.. But the price will probably be insanely high, but no harm in asking..... I have asked the prices for 5 and 10 pcs. No use asking for lower amounts.

I think this was the thread I was looking at regarding fake CPUs
