1. MIT OCW

1.1. 18.02 - Multiple Variable Calculus

1.1.1. Session 88-91

2. Emergency Crystal Radio

2.1. Finished desoldering switch

2.2. Radio constructed

2.3. Need to test

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. small graphics display

10.1. Use 320x480 OLED display and ESP8266+WiFi

Can write to display

10.2. VT340+Regis graphics (Abandoned)

OLED display cannot hardware scroll in required direction

10.3. Direct btmap interface

Cannot find suitable existing image format for memory constrained receiver, so constructing a new format.

11. mcd05 32 button/led box

11.1. Recovered schematics.

11.2. Planning software.

12. ca-r

https://github.com/daniel-kelley/ca-r/issues/34 Another ancient stalled project trying to be completed.

13. More project ideas

13.1. Zuse Z3 simulation in Verilog

Good excuse for floating point ALU design.

13.2. GMPForth ports to SIMH

13.2.1. SIMH maybe some targets (vax)

13.2.2. MAME looks interesting for microprocessor system emulations

How to support erzatz systems?

13.2.3. Ports to classic figFORTH targets

13.3. GMPASM assembler

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

13.4. Extracting ISO Superboard Forth ROMS for MAME emulation

13.5. 'bwocl' OpenCL tooling

13.5.1. Offline compilation

13.5.2. Standard Kernel Running

13.6. hardware support for classic 5V CPUs

13.6.1. RTX2000, CDP1802 still available!

13.6.2. 6502, 68000, 320C30, others on hand

13.6.3. CPUs with async bus may be supportable without RAM

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

13.7. Existing 'retro' hardware still working?

13.7.1. OSI Superboard

Unknown

13.7.2. Super Jolt
