I'll be posting more on this later, but my "final" hardware acquisition for the foreseeable future has just happened: a Commodore 128D (NA version - metal case).
I'm probably going to be getting the machine in the morning. But tonight I received the NOS keyboard. I saw a gentleman on Ebay selling one that was still in the original plastic baggie, so I reached out to him. Turned out he had another he was willing to sell me for much less (that original C= bag is worth more than its weight in gold).
Anyway, the keyboard arrived tonight via USPS. I have to say, it looks amazing. (Note: my kitchen lights use yellow bulbs).
