1. MIT OCW

1.1. Done for the year.

2. Mill Controller #2

2.1. Mounted on display enclosure

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. Received ML1220 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. Done.

8. small graphics display

8.1. TFTP rgb 565 graphic works.

8.2. Hope to never use ESP platform ever again.

8.3. Done.

9. RIOT drivers

Implemented - needs testing.

9.1. WS2801

9.2. Velleman KA03

9.3. Velleman KA05

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.

10.3.3. Consider simpler architecture with STM32F767 as a 'hub'.

11. AMD 2900 bitslice computing

11.1. Probably my oldest uncompleted project

11.2. Exploring possibilities for something constructive

Create verilog models for 2903/2910 and verify against hardware?

12. More project ideas

12.1. Zuse Z3 simulation in Verilog

Good excuse for floating point ALU design.

12.2. GMPForth ports to simulators

12.2.1. SIMH for 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 available!

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

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

12.6.6. Started planning for 6502.

12.7. Existing 'retro' hardware still working?

12.7.1. OSI Superboard

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