One quick observation: when Grant's instructions disagree with MITS's, make sure you give precedence to Grant's. I just wasted a day tracking down why my CPU wasn't working right and the problem turned out to be that I forgot to follow Grant's suggestion on P12 to replace R42 with a 4.3k instead of MITS's 6.2k.

Hi Geoff,

Yes it has been fun so far. 800 pins were soldered on the motherboard yesterday. I got the 18 slot with 8 slots supplied. It is a beauty!

Today, I worked on the D/C board - just partway through fitting the LEDs into the front panel. Every LED was tested before installing. I think I checked C7 and C8 5 times to make sure they were the right values!

I am definitely cross checking everything against Grants manual! It helps a lot. I like the way that Grant has preserved the board down to the mistake 'C' mark for SC13.

Cheers
Kelly
