ZX81 ULA-in-a-CPLD
Re: ZX81 ULA-in-a-CPLD
Yes, that price is more than acceptable
The danger might be that at low prices the demand might be quite high.
I'd take five for example.
Andy, are you soldering them manually?
Any other plans for the coming years?

In theory, there is no difference between theory and practice. But, in practice, there is.

Can Sell my Retro be used for preorder? Then you will know how many to produce.

Re: ZX81 ULA-in-a-CPLD
I have ordered 100 PCBs i don't forsee any problem getting hold of components, passives have been ordered in bulk ( relatively low price ) I have cplds for 30, but will likely order more immediately. Yes I am hand soldering them, getting rather proficient at those 0.5mm pitch qfp I have included a few quid in price for my labour time.
Perhaps a bulk order for our German brethren can be worked out that would at least save some postage costs.

Re: ZX81 ULA-in-a-CPLD
@Andy, if you up the price to say £30, you could almost retire at this level of demand
Of course, you would want someone who suggested this idea not to loose out, so would supply him (me) with a couple of units at cost price (£15)

There are four lights!
Step up to red alert. Sir, are you absolutely sure? It does mean changing the bulb
Looking forward to summer being good this year.

Re: ZX81 ULA-in-a-CPLD
Could I reserve a couple from the first batch please
Re: ZX81 ULA-in-a-CPLD
For you Mark I'd be quite happy to do a BOGCT offer... For clarity that is Buy One Get Charged Twice
However it's not really my intention to become rich, I believe a fair price that includes something for my labour is better for everyone.
