1. MIT OCW

1.1. 18.02 - Multiple Variable Calculus

1.1.1. Session 84-85

2. Emergency Crystal Radio

2.1. Need to finish desoldering switch

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. have another 3 wire fan from DET which may be less noisy

8.3. need to get 4 wire chassis fan

9. marble computing

9.1. Programmable Marble Gate Array

9.1.1. Logic table to operation 'compiler' done

9.1.2. Nucleo-f303re controller IO done enough for servos

9.1.3. Waiting for servos

10. samll graphics display

10.1. Use 320x480 OLED display and ESP8266+WiFi

10.2. VT340+Regis graphics

11. quilt table stands

Small stands for quilt table to support opened table over quilt frame. Good thing they were simple because in the end turned out to be unnecessary - the quilt frame can be adjusted to support.

12. More project ideas

12.1. Zuse Z3 simulation in Verilog

Good excuse for floating point ALU design.

12.2. GMPForth ports to SIMH

12.2.1. SIMH maybe some targets (vax)

12.2.2. MAME looks interesting for microprocessor system emulations

How to support erzatz systems?

12.2.3. Ports to classic figFORTH targets

12.3. GMPASM assembler

May be useful for handbuilt and rare systems (DMX1000?).

12.4. Extracting ISO Superboard Forth ROMS for MAME emulation

12.5. 'bwocl' OpenCL tooling

12.5.1. Offline compilation

12.5.2. Standard Kernel Running

12.6. hardware support for classic 5V CPUs

12.6.1. RTX2000, CDP1802 still in production!

12.6.2. 6502, 68000, 320C30, others on hand

12.6.3. CPUs with async bus may be supportable without RAM

12.6.4. Use Nucleo w/ 5V tolerant IO as boot loader controller

12.7. Existing 'retro' hardware still working?

12.7.1. OSI Superboard

Unknown

12.7.2. Super Jolt
