Not quite... The end of the ROM based PLA for the 64

[levoman]

Yes that is what PCBWay offer , pushes the price from $5 to $39 for 1um of dipped gold coating. more for 2 or 3um.
I will admit that is not bad if you buy 10 boards rather than five as it costs no more for ten as opposed to five!!

( plus delivery of course! )

I have noticed that with PCBWay if you leave it at five boards it is $5 if you select ten boards it is still $5 ?????

That works with enig as well so ten boards cost $39 + post !!!!!!

2um $62 and 3um $86.

Check JLCPCB for ENIG. Much better price AFAIK. Minimum quantity is 5 units.

To get the reduced price i can only have green or black any other color is extra.

IMHO, If you're going to have a PCB destined to be inserted in a female edge connector then having gold on the contact fingers matters far more than the color you choose. They could be Barney the Bear's fluorescent pink for all I care.

Yes that is true , however , just pointing out that PCBWay is cheaper for certain colors!

yes , i did spot it . It looks very nice but i am afraid that i am not much of an artist , more a functional type of person.

Got myself that HP 54601A. does not seem as good as the tektronix or the hameg but i will have to see how it performs. It is 4 channel , digital and with storage and 100mhz so it should do the job!

The 16 channel 100mhz logic analyzer has arrived as well ! I think that if it performs to spec it might be the better option. I know it won't show the glitches as good , if at all but it is the timing i am looking for.

Hi eslapion & levoman,


No matter if you not an artist in the graphical sense.

Looks like a very nice oscilloscope you have there levoman. Much more modern than mine, plus 4 channels no less!

What did it cost you all up?


Gee, I love how the auto calibration button on digital oscilloscopes saves me. I can really make a mess twirling the dials and pushing all the buttons nonsensically, Ha!

I've sent off a message to Bella at PCB-way asking the different price points on Gold plating of boards. Hopefully, she will be able to give us a clearer picture on costs.
I should check the prices on the competitors sites........

about £93.00 including postage and the 10uf 25v capacitor to fix it!!!

Hi levoman,

WOW! That's a great price, good buy....

Have you got any pictures of the glitch on. A dodgy PLA?

[levoman]

Have not used it yet , been busy elsewhere.

Will post some pictures when i get a chance!

My website is now up and running!!!

Sorry that is not available yet! Still trying to get my head around joomla the site building software. Will update as i can. Pick from the list at the top left to see pages.

Ordered some enig , green , zaxxdual pcb's from jlcpcb , they work out about £3.00 each including the postage. Should be with me in just over 2 weeks.

[levoman]

The new boards have arrived!

ZaxxDual is now out of prototype!!!

And i have just noticed that the High and Low bank on the 512k are the wrong way around. Will correct it and re upload.

[levoman]

eslapion do you have any 90b6's left? i would like to purchase one to use for comparison with a PLA the same as the rest.
