DIY builders & Homebrew Tinkering ?


Recommended Posts

Some of you may of noticed that I was selling Z80 kits on ebay for those interested in tinkering with electronics and microcomputer design.

 

I've talked Funkward-tech into selling these kits, and bespoke customs kits on ebay.com. (As i've stopped selling them !)

 

You can either buy from their website or buy direct and get wholesale prices just contact them if your interested..

 

Some important things when buying from China..

 

If buying direct, tell them your TARGET price ... the price you want to pay
Check ICs as soon as they arrive.. They will send replacements if any are DUFF.
Tell them to use static Sensitive precautions as they may not.
don't let them 'Overcharge you' !
