1. MIT OCW
1.1. 18.02 - Multiple Variable Calculus
1.1.1. Session 79-83
2. Emergency Crystal Radio
2.1. Need to finish desoldering
3. Mill Controller #2
3.1. Repurpose 'boss' hard drive
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. need tooling to edit sample files
6.2. increasingly skeptical whether quality results are possible
7. gat
7.1. spectrogram done - matches 'octave' output
8. abby
8.1. installed three wire chassis fan - too noisy
8.2. need to get 4 wire chassis fan
9. marble computing
9.1. Programmable Marble Gate Array
9.1.1. Logic table to operation 'compiler' mostly complete
9.1.2. Nucleo-f303re controller in progress
10. More project ideas
10.1. Zuse Z3 simulation in Verilog
Good excuse for floating point ALU design.
10.2. GMPForth ports to SIMH
10.2.1. SIMH maybe some targets (vax)
10.2.2. MAME looks interesting for microprocessor system emulations
How to support erzatz systems?
10.2.3. Ports to classic figFORTH targets
10.3. GMPASM assembler
May be useful for handbuilt and rare systems (DMX1000?).
10.4. Extracting ISO Superboard Forth ROMS for MAME emulation
10.5. 'bwocl' OpenCL tooling
10.5.1. Offline compilation
10.5.2. Standard Kernel Running
10.6. hardware support for classic 5V CPUs
10.6.1. RTX2000, CDP1802 still in production!
10.6.2. 6502, 68000, 320C30, others on hand
10.6.3. CPUs with async bus may be supportable without RAM
10.6.4. Use Nucleo w/ 5V tolerant IO as boot loader controller
10.7. Existing 'retro' hardware still working?
10.7.1. OSI Superboard
Unknown
10.7.2. Super Jolt
Unknown
10.7.3. Ampro Little Board
Not booting. Needs analysis.
10.7.4. Rockwell R65F11 Demo board
UART spits out something but may have settings wrong.
