1. MIT OCW

1.1. 18.02 - Multiple Variable Calculus

1.1.1. Session 86-87, pset11

2. Emergency Crystal Radio

2.1. Need to finish desoldering switch

If I can find it…must of put it in a "safe" place.

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

Can write to display

10.2. VT340+Regis graphics

11. More project ideas

11.1. Zuse Z3 simulation in Verilog

Good excuse for floating point ALU design.

11.2. GMPForth ports to SIMH

11.2.1. SIMH maybe some targets (vax)

11.2.2. MAME looks interesting for microprocessor system emulations

How to support erzatz systems?

11.2.3. Ports to classic figFORTH targets

11.3. GMPASM assembler

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

11.4. Extracting ISO Superboard Forth ROMS for MAME emulation

11.5. 'bwocl' OpenCL tooling

11.5.1. Offline compilation

11.5.2. Standard Kernel Running

11.6. hardware support for classic 5V CPUs

11.6.1. RTX2000, CDP1802 still in production!

11.6.2. 6502, 68000, 320C30, others on hand

11.6.3. CPUs with async bus may be supportable without RAM

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

11.7. Existing 'retro' hardware still working?

11.7.1. OSI Superboard

Unknown

11.7.2. Super Jolt
