Hi!
Yay! Just received my Core PCB (thanks again Smash!)
I am going to order some samples to build my first MB.
I am wondering, for MIOS (future project) what chip is needed?
PIC18F452-I/ML; PIC18F452-I/P; PIC18F452-I/PT; PIC18LF452-I/L; PIC18LF452-I/P; PIC18LF452-I/PT
For the MB64: PIC16F877-20? (Not available as free sample?)
And finally, for the BankStick chip: ? (Heard you could get those as well but I’m not sure…)
Anything else I should get?
TIA!
Youb need the 18f452 i/p. Ordered those from the sample site also. hmmm wonder if my 40 days are up so i can order some banksticks ;D ;D ;D

I can’t take any credit for that, I merely passed them on in behalf of a very cool Midiboxer. :)
Have Fun!

18F452 I/P is definitely it, The banksticks I got were the 24LC256I/P, and I also got the 24LC512I/P, cause you never know what the future may bring.
Nice! Thank you 
Any info on the 16f for the mb64? There is the 16f877A that seems available as a sample, would that do?
Smash: you’re right so here is the correction:
Thanks anonymous MBer for the cool gift and thanks Smash for all the rest
Bump! (Just to make sure no one knows 
)
I don’t mean to be annoying but could some1 clear up this question for me?

How or indeed where do you get these free samples?
Hi there!
microchip is giving free sample pics… you can get them on their website at http://sample.microchip.com/
I was just asking about if I could use 16f877A instead of PIC16F877-20… otherwise I’ll just buy a 16f877a!
Yes, the PIC16F877A is working, you only have to take care with the JDM programmer. This chip has a special setup, and you need to increase the IO delay to 20 in order to lower the programming voltage.
Best Regards, Thorsten.
ok so I just need to build/configure the JDM module differently?
Will that affect performances in any way?
Thanks! this project is getting me very excited but I don’t know that much about electronics
JDM stays the same. IO delay is a menu option in IC prog
OK nothing else will change right?
I’m gonna place the order today!
I’m also trying to scavenge a DIP housing from an old motherboard for my pic Unsoldering is harder than I thought hehehe
EDIT: ACK! Is it the pf16f877a-I/P or pf16Lf877a-I/P
I’d say the first one but I want to be sure (can’t understand the difference between the two)
I should be done asking questions about that after this one
That was a stupid question NM
why don’t you just order the regular pic16f877-20 (20 means 20 mhz, make sure you order a 40 pin version, P and I/P just refer to the temperature range, I/P is for hotter environments I think. Both will work in a midibox) from microchip? Order a pic18f452 while you are at it, for future upgrades. (and a bankstick chip) Even though you will wait for your free sample, you will be building the rest of it while you wait anyway.
Thanks for those additional details, it really helps
As for the 16f877-20 it wasnt available as a free sample so that’s why I took the other… I could’ve ordered it but I’m not really good in electronics so I prefer to “practice” on free chips
I got some banksticks as well as the 18f too
Microchip stopped shipping to australia :'(.
Yeh when I start making synths professionally, you know who’s products I WON’T be using!
Bastards… I saw their logo on a champcar race last night… For the price of that Ad they could have shipped enough PIC’s to bury me alive!!!
Still that 18F is pretty impressive ;D
I got my samples from Microchip after 2 weeks, even though they said 4 months, so worth going for even if you think your box will be finished by the time they arrive.
I got a free sample… including pic16f877-20, and I live in Australia, that was about 2-3 months ago max… There is a microchip office in Epping, Sydney. (though I ordered from the website, took 2 months to arrive!!)
