Posting will slow for a while

So I’ve gone back to work after an extended holiday, so output is likely to slow for a bit. However, I’m still doing retro “stuff” so I thought I’d share some of it.

Having said that, my SE/30 needs to be broken down and the Digital board needsContinue reading “While I wait for orders to arrive”
