Did a full restoration of my wife’s Grandfather’s TI-58C. They are notorious for bad ram and this one needed replacing. Also converted it to a DC wall plug. Now accepts assembly language programs and the built in functions work. Very cool late 70s tech. But .27 amps, yikes!

I managed to enter all 196 Bytes of Lunar Lander by Jim Butterfield (BYTE April 1977) by hand with no errors on the first try. Such a fun game and a great way to learn 6502 Assembly programming the hard way. #commodore #shortcutsareboring

I’ll do most programming over serial from here on out. But from an 8 Bit computer thank you very much. These Striketerm settings work great with my serial adapter on my C64

Got this KIM-1 replica together in a couple hours tonight. Was a fair bit of soldering but now I can computer like it’s 1976. 17 instructions to do a counter. Tomorrow morning we’re playing Jim Butterfield’s Lunar Lander on this thing! #commodore

Mentioned yesterday I’ve been going through this Math for Deep Learning book this week. The examples are all in Python, so I’ve been reimplementing every one in Julia. This not only gets me to really think about what I’m doing, but strengthens both my Python and Julia chops
