Another Egyptian Enterprise 64

So whilst waiting for the replacement RAM to arrive I decided that I need to make a start on the FDD interface (@stephen_usher I've been saving your video for building this) so started the build box for it today.

Not a surprise, I didn't have all the parts for it, so those are all on order now and I'll make a start building it whilst I wait for those to arrive.

There's plenty to be getting on with though as I did have quite a lot of the parts in stock.

OK the FDD interface is coming along nicely:

Spot the deliberate mistake, now corrected


One a small issue with the inductor because I ordered a part that was too small:

New one on order, hopefully the right size this time!!. I also managed to order only one LS240, silly mistake now on order too. Just waiting on some resistors, the LED and I need to find a switch and dig out a 1772, which I know I have some of.

I reckon I'll finish the FDD card before I get the replacement RAM for the expansion at this point, I ordered it 5 days ago from a supplier I use a lot and it still hasn't been dispatched...

EDIT: Memory was dispatched this morning

Oh, you're going for a full fat version.

Yeah I went for the diet Pepsi version myself

I am, I can't abide an empty socket

[rubber_jonnie]

I'll probably end up at the diet Pepsi version but I'll start full fat

Well the FDD controller is built:

So I need some disk images to test and instructions on how to do so

No Sign of the replacement RAM IC yet though it is supposedly in the post. Bizarrely the RAM test is now passing, though I am still suspicious of the RAM IC on the expansion.
