He/him. This is one of my alter egos in the retro world. Read about this instance on front page. My goal is to be able to post here from a 286* running DOS. Might be a while..

and enthusiast with a craving for retro (mostly PC) hardware. Four kids and a wonderful patchwork family.

And it lives! Apparently I'm officially operating a Motherboard Bakery! :)
Now I need to get it properly configured and tested with DOS, then I can move on to the next steps - which involve the CPU upgrade, and assuming that works, creating actual, physical floppies.

(In other news, the instance on this poor Pentium Pro server is sweating hard whenever I post something. So let me know at @ltning@anduin.net if you have problems receiving/reading my posts. I've made some tweaks but it will be unavoidably detained for a while following each post, my apologies for that..)


Picture of BIOS during boot. It's a 1990 American Megatrends BIOS, for the TD60C board, BIOS version 2.42B. It shows a 20MHz CPU clock and 15872 KB RAM tested OK.

    Dark-ish picture showing motherboard mounted horizontally on a transparent acrylic surface. Underneath a combined 5.25 inch and 90mm floppy drive. The installed RAM lights up in different colours, four sticks with blue, purpole organge and yellow LEDs, respectively. VGA, network and sound cards are also visible.

      @ltning any 286 over 16mhz is a unicorn!
      Great find!
