A deep interest in the pre-Windows home computer revolution, specifically the 8-bit, Commodore, and Amiga scene that defined that period of immense technological change for the home computer user.

While I wait to test my mods... Not even Halloween and I'm scared out of my wits 😱 as I cut into a 40 year old plastic case for the Magnavox CM8562 (a sister of the Commodore 1084) in order to add analog RGB via the DIN and SCART ports. But I think I did ok! 😏

At the same time as the 1530, I acquired this lovely board. Has faults, but looks like new. I suspect it's either a faulty VIC-II or the LS258 at U14. Not ruling out the old PLA or its associated logic U15 / U27 though.

As CeX offers to take retro tech trading into the mainstream, there's going to be profit margins and taxes to consider, and the middle-aged men of This Week in Retro are all over these details for your weekend enjoyment.

While I wait.. I made feet! Got a Magnavox or Commodore 1084 variant with worn down or missing rubber feet? Print your own! Curved bottom feet, great for printing out with ABS, PLA, TPU, or Siraya Tenacious resin or print flat bottom feet & attach rubber bumpers www.thingiverse.com/thing:7401701

It passed the smoke test! No magic smoke!! 👾🎉😁 6 caps, 3, diodes, 27 resistors, and 9 transistors later, the composite is still working 😆 I don't have anything to test the RGBi. I have to create a cable to test the Analog RGB (the changes I made) - those parts don't arrive until tomorrow. 🤞

Can this Magnavox RGB 80 be converted to a Commodore 1084? ... more to the point -- can >> I << do it!?!? Tomorrow the smoke test. 🚭 👀 Friday, I'll build a cable .. and maybe get to test to see if it works!

So I got my hands on a Magnavox RGB 80 (CM8562) .. which a sister of the Comodore 1084 .. one of the variants. It only has composite and RGBi (CGA) .. but on the motherboard, there's circuitry for Analog RGB ... should I add in those missing parts ... or ?!?

The Commodore Amiga 1000 is all back together! Nice and clean inside, though I still have to inspect and detail the keyboard. The Parceiro II+ really does a good job updating the system with 8MB of RAM and SD card hard drive partitions -- it loads Kickstart and then boots into Workbench right away.

That Commodore Amiga 1000 that I've been working on .. it's amazing it still works after all these years. All I've been doing is cleaning it up. I didn't have to fix a thing. "Refurbished by Commodore" Cleaned by me 🥰

The Commodore Amiga 1000 almost all back together. I had to test everything to make sure there were no problems. 🎉👾 .. it powered up perfectly! Time to get the cover back on and snap in the Parceiro II+
