Just collected this....
« on: 20:25, 08 November 17 »
.... For 20eur it was worth a punt if it works or not.

At the moment power led is good, but nothing else so probably ram gone bad.

But it has an usual combination of French keys with qwerty layout. Anyone else encountered such a beast?

Hope you get it working.  :)

Looks like someone has just swopped the keys over to me, the heights are wrong.  ???

Can you stop posting pictures from your phone until you've worked out how to sensibly size the pictures?

Whilst sitting in ikea I have installed a 2nd camera app. @Bryce does this suit your eyesight better?

What about a sensible auto-resize option instead?

I think the problem with those types of forum mods is that they no longer allow the other picture options such as thumbnail etc? But I could be wrong.

OK, back on topic....

RAM is gone for sure. It's a cost down board. Anyone recognise that rom? Looks a bit "custom" to me. Possibly unsoldered.

Currently burning the lower rom RAM test.

That's an EPROM, so someone has replaced it in the past.

Bryce.

P.s. Nicely sized pictures by the way :)

12.45 eur for 8 new 4164s and 2.94 for 10 sockets.

Edit: I cannot feel a depression for the window of that rom/eprom. It will be very interesting to get it up and running and find out how the machine behaves.

Also nicely sized cost down board. I knew these were small but I did not realise they were *that* small. Serious room for Internal expansion. I wonder if I could shoehorn a symbiface 2 and ide to sd card reader into the case?

You also have the option to use 2 64kx4 bit instead of the 8x64kx1. It' the 2 empty footprint next to the pre-asci. It may be cheaper  ;)

It might have been as I have some 41464 ram here already. Ahh well ordered the original fitted parts now.

Step one done. All old ram removed. No lifted traces. My neatest desolder job ever... I'm getting better at this shit lol!

Hopefully I won't have to send this one to @bryce for an "oops I f*cked up" type repair.

I thought the same thing but I didn't mentioned that as it would be the ultimate trolling  ;D ;D ;D

So having taken the 'oh so small' board out today to desolder the ram (I am just gonna replace the lot) I think I have found a solution to internally mount a symbiface 2 (I have 2 of them afterall) but this raises a question....

What is the best option for fitting a ribbon cable inside a cpc case. Strip the ends of the cable and solder onto the centronics mounting points? Fit a centronics connector backwards (pointing into the case) and then use a ribbon cable with every pair of 2 wires twisted? Or something else. Ideally I still want a working expansion port for an m4 board!

OK last problem with this cpc.... Tape counter! Has anyone got a 3d printable reset button file? Or a part number for a compatible replacement counter?

Off-Topic:
Off-topic again, but no additional mods are needed on the forum, assuming you post from the desktop; when uploading an image you have the option to post inline, end-of-post, thumbnail or original. As Bryce said, other mods will probably interfere with this functionality...
