PhilC's H4 Mongrel edition build x 3

[PhilC]

Finally remembered to feed Harry, so it's over to you exxos...... no rush..... :poke: :poke: :poke:

How’s the prep work going PhilC. I see derkom has started gathering components. I think this is going to be another epic adventure :)

[PhilC]

I've got enough parts for two complete boards, maybe 3 if I finished scavenging other boards first I think.

I think I'm probably going to play skip the sockets on the mfp, shifter etc after the hassles we had with the Alpha, I'm probably also going to build one with the smt MMU etc as well I think.

Then once it's done, got lots of toys lined up to test it with, including a TF534 or two :twisted:

What about you Icky?

Ah ha.

Well one of mine I am going to do similar to your thoughts above and skip sockets and solder in the chips directly. I will test the chips out on the original Alpha to make sure they are functioning correctly before soldering in. I will socket a few still such as the shifter so I can test out Smonson's HDMI / DVI shifter etc on the H4.

I have a firm belief that this board will be a lot easier to get up and running as it is basically the Alpha with all the fixes etc in place. We have been pouring over the schematic and board and have fixed a few items as we have spotted them. We expect we will have one or two minor patches (no towers - famous last words) :)

One of the other boards I am going to build it a bit differently as I want to use it as a development board for the next revision after the H4. i.e. I want to be able to plug in the FPGA Blitter etc.

Fixed Alpha yes - working board, its a new board with a ka-zillion changes, so no :P :lol:

Has anyone noticed the "lack of" TTL chips on this new board yet...

:hide: :hide:

I'm going with full optimism on the H4 - ;)

I'm too scared to look any more exxos.

Anyway, I'm hoping the H4 will be easier, especially with lessons in fixing learned whilst working on the Alpha.

As for towers, I'm sure they will appear once or twice 8-)

So, these arrived today.

Parts arriving tomorrow as well, so looks like I've got some catching up to do.

But first time for a hot chocolate.

New mug @PhilC ? ;)
