How is the Project coming on ??

Hi Audronic (Ray),
It was all put aside because my son had come to visit. He has just left recently.
I had a computer crash so I am having to start over with a couple of things. I have three projects that were put aside. One is a TRS-80 clone with VGA output and the other is a custom retro computer (also VGA) and this one of course.
I was just now thinking that I should order a Disk On Module for this.
Here is were it was 'at' from memory -
At one stage I did see a "Hello World" on the CPC that was written to the CF card on the PC so I had something going. I was getting memory corruption and I was suspecting a PSU. I did go and buy another PSU though. I don't have a scope for debugging analogue issues.
Also, both CF cards I am using came from the same place in China so I should go and buy another just in case both are faulty.
I was at the point of re-viewing all stages of the build - pinouts - specs. I remember that one of the CPLDs that I use here has a pinout error on the data sheet so that may be an issue.
So I am going to start over. I have to set up the project first as it's been packed away.
I have a logic analyzer here now so perhaps I will set that up. I have the Altera and Xilinx platform running on my laptop now as well. The pore thing is only a duel core and struggles. The desktop was a quad core - I might try to fix it.
So - I should be back here this coming week hopefully - if I don't end up spending too much time on the other projects.
On another note I have been completely retro and using wire wrap for one project lol.
