1. MIT OCW

1.1. 18.02 - Multiple Variable Calculus

1.1.1. Session 100-102

2. Mill Controller #2

2.1. Repurpose 'boss' hard drive

S/W configuration done.

2.2. Need to investigate new HW/SW for eventual replacements

2.2.1. Old crap ain't gonna last forever

2.2.2. Buildroot/Linux 5.15 PREEMPT + latency tools

First pass done - boots on real hardware

3. Alum Rock Data Center

3.1. need to check rocky, others? (arch?) for suitability

4. OLPC

4.1. Needs ML1120 coin batteries to fix "invalid system date".

5. Virtual Orchestra

5.1. sfz file tests

5.1.1. need tooling to edit sample files

5.2. increasingly skeptical whether quality results are possible

5.3. maybe should treat as platform for concatinative synthesis

5.4. maybe should just accept the limitations and work with it

One should not be disappointed that a guitar can't sound like a flute.

6. gat

6.1. spectrogram done - matches 'octave' output

7. marble computing

7.1. Programmable Marble Gate Array

7.1.1. Software complete (enough)

7.1.2. Ball sensor

Lite-on 15mm slot sensor effective.

7.1.3. Rework hardware

Eliminate all taped on part mountings (which are most of them!).
Use type-t-parts below for some supports (platform server, boards).

7.1.4. Display

Don't need. Use term CLI for now.

8. type-t-parts

C++ program(s) to generate 3D printable Type T parts.

9. small graphics display

9.1. Use 320x480 OLED display and ESP8266+WiFi

9.2. BWIF (Barely Working Image Format) designed

9.3. pamtobwif/bwiftopam mostly complete

Debugging. Large and small uncompressed bit/gray/pixmaps works on round-trip PAM comparison test.

10. mcd05 32 button/led box

10.1. Recovered schematics.

10.2. Planning software.

10.3. Received STM32F767 Nucleo144 with Ethernet.

10.3.1. Test program running.

10.3.2. Need to consider CoAP multicast discovery.

11. More project ideas

11.1. Zuse Z3 simulation in Verilog

Good excuse for floating point ALU design.

11.2. GMPForth ports to simulators

11.2.1. SIMH for 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 available!

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

11.6.5. Could use small foorprint monitor in asm (gmpmon?)

11.6.6. Started planning for 6502.

11.7. Existing 'retro' hardware still working?

11.7.1. OSI Superboard

Unknown. Composite to VGA adapter didn't seem to work. Needs analysis. Found OSI model 610 board underneath!
