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.

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' !


Below is a rough guide to the prcies I paid for some ICs, this may be useful when costing a project ?

I've bought stuff direct from them, pretty good, items arrived OK, though stuff from China can take a while to arrive ! Will replace any damaged or not working items.

The V9990 ICs are quite expensive... I suppose because they are more difficult to source.
The OPL4 YMF278b are obtainable but i don't know the price off hand.

Practically all the ICs needed too build an MSX 1 & 2 are still available either as NOS (New Old Stock) or as working pulls. Never seen any R8000 CPUs.. Don’t think you'll get these if you wanted to build a Turbo R !

if you fear to pay 20 US$ for a v9990, you aren't part of that niche market!. That price for the chip is just fine.!
