What else but an Atari 1040 box cut down.
Re: PaulJ's H4 Mongrel Build x 2
Have almost all the discrete components and surface mount stuff installed. Most likely will not put on the 16 mhz osc since it covers 99.5% of the pads. Missing the 75 ohm sm resisters. They were backordered. Shesh... usually check that everything is shipping. So I had to place another order to cover missing items. They should be here Wednesday so I expect to power up on Thursday baring any more missing components.

Re: PaulJ's H4 Mongrel Build x 2
Coming along nicely @PaulJ.
Re: PaulJ's H4 Mongrel Build x 2
Pretty much finished up with the parts I have. Ran into one part I'm short, SN74LS07.. 
Is there something I can use until my 07 shows up wednesday? The 75 ohm SMT resisters show up Tuesday but I can run without them with the diagram. So were getting there.

Re: PaulJ's H4 Mongrel Build x 2
You have to use the correct parts
Re: PaulJ's H4 Mongrel Build x 2
Realize that but sometimes there are parts are close enough where you can substitute. Shesh I even ask Phil if there's something I could plug in backwards that would work.
Guess I'm just going to wait. Re: PaulJ's H4 Mongrel Build x 2
Well everything showed up today so I have finish building the board waiting for that pesky sn74ls07 which should show tomorrow. 
I do need to set all the jumpers since a lot of the pins were not installed when I set them initially. So planning to shoot the juice to it tomorrow and check for any of @PhilC magic smoke.
