Turns out serial cable was attached to a Keyspan. Double win and it only took me a half hour to find. Now who’s gonna clean up this mess?
Desoldering 16 memory chips with 16 pins each is NOT something one should do when feeling impatient. I got them all without a single lifted pad. This 128 will live to fight another day.
The next two parts of the Cipher series are on Symmetrical Encryption and the algorithms take quite a long time to run at 1Mhz. Having a portable rig has been really nice.
After listening to an episode of @GUp80s with @DarrenFoulds and @8BitShowAndTell I’ve gotten back into one of my favorite games: Mastermind. So simple, but it’s a good conference call thing. There’s a great port of the IBM version to the 64.
My childhood best friend has never really been on social media and checks email every other week. I asked his wife the best way to chat with him. He overheard the conversation on the phone and sarcastically said “mail me a floppy”. I thought, well okay, 3.5 or 5.25? #thatwaseasy
10 Minute lunchtime progress: My 6502 experiment board is fully working. Love the way this turned out. #commodore
I haven’t done HAM radio stuff in a couple years now, but this combination may rekindle this interest. My call sign is N4LNX #commodore #c64 #hamradio
Off on a pre workout tangent this morning. Decided to dump the SID output for 16Mb to look for evidence of that 23 bit LFSR. I can’t actually find repeats at all and this should be 24 bits. #commodore #c64
10 minute evening progress: This is moved over from the breadboard onto a compact (and neat) PCB. Last thing is the Arduino HAT daughterboard, but I’m thrilled with this at the moment. How it started, how it’s going. It’s got #commodore bones anyway ;-) 6502 is my favorite.
