1. MIT OCW
1.1. 18.02 - Multiple Variable Calculus
1.1.1. PS9 con't.
2. Emergency Crystal Radio
2.1. Broke inductor selector - oops. Fix/replace?
3. Mill Controller #2
3.1. Try Alpine Linux
3.2. Need to investigate new HW/SW for eventual replacements
3.2.1. Old crap ain't gonna last forever
3.2.2. Buildroot/Linux 5.15 PREEMPT + latency tools
First pass done - boots on real hardware
4. Alum Rock Data Center
4.1. Using CentOS 7 for now - good until 2024?
4.2. need to check alma, rocky, others? for suitability
5. OLPC
5.1. Needs ML1120 coin batteries to fix "invalid system date".
6. Virtual Orchestra
6.1. sfz file tests
6.1.1. Started new audio tool program to replace aftools
7. i5 system
7.1. delicate primes
7.1.1. Verified 294001 is a delicate prime in base 10
7.1.2. Determined 294001 is delicate in bases 2 and 10 but not in bases 3-9,11-16
7.1.3. What is the smallest delicate prime N in any base 2..(N-1)?
Does this question even make sense?
7.2. i5-12600K CPU
7.3. 32GB DDR5 mem
7.4. 512GB SSD
7.5. AMD Radeon RX 6800 GPU
7.6. ~100 compute cores across all devices
Hopefully won't have to do this again for a while. This blows the toy budget for the year.
8. More project ideas
8.1. Zuse Z3 simulation in Verilog
Good excuse for floating point ALU design.
8.2. ENIAC simulation in verilog
Probably too big a nut to chew.
8.3. GMPForth ports to SIMH, DYCyber targets
8.3.1. SIMH maybe some targets (vax)
8.3.2. DTCyber suboptimal due to data/addr word size mismatch
8.3.3. MAME looks interesting for microprocessor system emulations
How to support erzatz systems?
8.3.4. Ports to classic figFORTH targets
8.4. GMPASM assembler
May be useful for handbuilt systems.
