  1. I’ve been following your Z80 playground playlist on YouTube. I fancy having a go at building your system. Would you be able to package this up as a kit?

    1. Yes, that is exactly what I am in the process of doing. I will make the kits available, plus a ready assembled version too if you would prefer that. Are you specifically interested in assembling it yourself? I am planning to put the kits on eBay for roughly £50. I will make sure you know when they are available. I’m on to v1.2 of the board now, and a new video will be appearing soon.

      1. I’m more interested in assembling the kit myself. Alternatively, as I already hold a number of the 74 chips, I would also be interested in purchasing just the motherboard PCB with monitor and a BOM.

        Good luck with the project.

    1. Ah, well a kit is even easier for me to provide. I’m in the process of working on the documentation etc. Do you want to contact me directly at “john ATSYMBOL 8bitstack.co.uk” and you could join the “early adopter program”?!?!?!

    1. You are right. This is actually the schematic for v1.1, and I am now on v1.2 so I will post the new schematic right away…

    2. But for the record, they are current-limiting resistors for the LEDs, so basically any value between 330R and 2K will be appropriate, depending on the LED you use. I used 1K with my ultra-bright 2mm LEDs and they were easily bright enough.

  3. Hi there:
    I’ve been following your Youtube channel for a while. Unfortunately, I arrived late for the Ebay offer.
    Is there any kind of list for the next batch?
    I would prefer to solder it myself, but I will be fine also with the assembled kit.
    Thanks in advance.

    1. Yes, the next batch will be in kit form rather than assembled ones. I’m ordering new components. We’ve got a new lockdown just starting here, but hopefully I’ll still be able to get on and make the kits up!
