I purchased a PiDP-11 kit in July 2019, and it has been sitting waiting for me to assemble it.  I ran across it a few days ago but have some questions before I start soldering.

Have there been significant changes in the kit between the 2019 version I have and the one currently being sold?  I know about the change in thickness of the plexiglass front panel.  Is there anything else?

Should I use the current version of the assembly instructions or the 2019 version I downloaded when I purchased the kit?

Depending on whether there have been changes since 2019, should I purchase the current version kit or stay with the one I have?

Thanks for any input.  Your opinions will be appreciated.

As far as I know, there are no significant differences, and I would just
start building the kit you have.

I built both an old version (serial number less than 10) and the later version using the same instructions, I believe. I don't recall there being any difference involving the circuit board and the electronic parts. The only difference I remember is in the acrylic panel and that some of the screws for mounting it are different sizes than the original. The sequence of steps for mounting both is the same, just find the functionally equivalent part and use that.

You should be perfectly safe with the kit you have, I would not bother getting the new kit.

But I suspect the current ones will be pretty close to the same.

Following is a copy of the message that Oscar sent out when he changed the kits to use the new, thinner, matte finish front panels.

Subject: Tindie orders: PiDP-11 kits of July 5th batch are on their way

 

Hi,

Just to confirm that I sent out all PiDP-11 kits for this batch. They are on their way with a track & trace code you can find on Tindie.com's order page.

Some important things:

  • In newer PiDP-11 kits the acrylic front panel is thinner, 2mm rather than the old 4mm. It's not a cost cut - rather the opposite. But: you need to put an extra nut on the 5 brass spacers to make up for the 2mm. Some people don't read my Building Instructions and just follow the 2019 Youtube video from Beige-O-Vision. But this crucial step is not in the movie. Do not forget it. Otherwise, the spacer is too long and can damage the case. In a picture: make sure you do this, or you risk damaging the case:

Other than that...

  • If you are in the US, the parcel is a sign-for-delivery parcel. Elsewhere, mostly, the parcel is simply delivered and a signature is not necessary.
  • If the postman does not find you at home, he might leave a note to pick up the parcel at the post office. Or you can arrange for a new delivery time online. Sometimes, people don't find that scrap of paper and the kit lingers at the post office. But if you do not pick it up soon, it'll be sent back to me...
    Therefore: IF YOU DO NOT RECEIVE THE PARCEL within the next 2.5 weeks, CONTACT ME BY EMAIL
    .
    We can check and see if it waits for you at the post office.
  • Don't worry about getting the kit working. I can always send you replacement parts if your soldering goes horribly wrong :)
  • Check the web site's Building Instructions page: http://obsolescence.wixsite.com/obsolescence/pidp-11-building-instructions

  • You can already prepare your Pi by (1) installing normal Raspbian on an SD card, and then (2) install the PiDP code following the steps in the manual (link).
  • A lot of action happens in the PiDP-11 and PiDP-8 Google Groups, so be sure to have a look there.

And, any questions or problems during the build process, do let me know!

Kind regards,

Oscar.
