Great kit!
For RC2014 Classic - Homebrew Z80 Computer Kit
This is a great DIY kit for those who would like to get into retro computing, Z80 assembly or to just learn the basic organization of a simple computer via hands-on experience. It requires a fair amount of homework getting all the ICs and other components you will need gathered together if you buy just the bare kit, but that is part of the fun. Also make sure to reference the schematics, photos and other docs on http://rc2014.co.uk/ as there isn't a compiled build guide that I am aware of. However, there isn't a huge need for it to be honest. The only issue I had was not knowing where to set the jumpers for the ROM board (0000-1FFF, of course). Also, if you want your kit to turn out like the one in the photos bear in mind that all of the boards do not face the same way when plugged in to the baseboard, but you'll want to solder the header pins to the modules all in the same orientation or else you may get a surprise when you try to plug the clock module in and find it hits the ICs on the RAM module. Just take your time and triple check everything before you start soldering.
One last tip, unless you get one of the new custom made backplanes use some masking tape or painter's tape to mask off the perfboard in nice straight lines on either side of the pins when you solder the female headers on to keep the bottom of the board from looking all sloppy.
If I get the time I will write up a guide based on my experiences and send to the store owner. I just got my hands on a EEPROM programmer and a blank EEPROM in order to do some assembly language programming. The author/store owner was very helpful in pointing me in the right direction for getting started on that.
