Mike Shipement Has Arrived

Today is a great day! Mike shipement has finally arrived. He prepared and sent them very quickly but the USPS and the french customs are so slow! :( ... but well, now they are here.

I appreciate the way Mike made the package: very serious and professional. All the components are in perfect condition, including the beautiful MIMEO PCB. The ICs are plugged in an antistatic foam which is a good thing. See below all the components I have now:

Below are all the rare components I got from Mike (ROMS, RAMS, Signetics chips...). They are all plastic but really vintage and in very good condition. Mike certified that they are tested and functional. I trust him 100%, he's a professional person.

The PCB is a masterpiece. It is really professionally done. CONGRATULATIONS MIKE! ... Today the project is becoming "real".

I Got The CPU And The PIA

I found the 6502 microprocessor and the PIA (Peripheral Interface Adapter) MC6820. I got them from a local enthusiast who was selling a few vintage components on Internet.

He was selling one used Rockwell R6502P in new condition. I contacted him "Do you have two of them?", he said YES! I also asked him "Do you have a MC6820?", he responded "yes, a vintage ceramic one"... WOW!! Excellent! I like these ceramic ICs which are hard to find. Today I received them, they are beautiful. See the picture below:
