History
2023-09-17: updated the rust toolchain via rustup update. Check
tingo@kg-core1:~/personal/projects/2023/rust/embedded/neotron/Neotron-Pico-BIOS $ rustup check stable-x86_64-unknown-freebsd - Up to date : 1.72.0 (5680fa18f 2023-08-23) nightly-x86_64-unknown-freebsd - Up to date : 1.74.0-nightly (7d9bce327 2023-09-16) rustup - Up to date : 1.26.0
2023-07-13: The Neotron Pico PCB is 244 x 171 mm, the largest size for a microATX motherboard is 244 x 244 mm.
2023-07-10: tried with a different monitor (HP L1940 T) this one get the full picture from the Neotron, both in logo and startup screens. Also reports mode as 640 x 480 @ 60 Hz.
2023-07-09: the monitor I'm currently using (Compaq TFT 8030) reports the mode as 640x480, Horz Freq: 31.5 kHz, Vert Freq: 60.0 kHz.
2023-07-05: added a CR2032 battery, and now the RTC remember date and time, as set with the 'date' command.
2023-07-04: SDcard - I insert a 64 GB SDcard (exFAT). Now the 'lshw' command tells me under Block Devices that SDCard0 has bs=512, size=59392 MB. The 'lsblk' command tells me the same, with other words:
> lsblk Block Devices: Device 0: Name: SdCard0 Type: SecureDigitalCard Block size: 512 Num Blocks: 121634816 Card size: 58.0 GB (62.2 GB) Ejectable: false Removable: true Media present: true Read only: false
when I try the 'dir' command, this happens
> dir Listing files on Block Device 0, / Error: FormatError("Partition type not supported")
so probably no exFAT support. I replace the SdCard with one that is FAT32-formatted.
> dir Listing files on Block Device 0, / 0 file(s) 0 bytes
yep, that was it. I put some files on the SDCard (from the Neotron-SDK repository) and now I can see them with 'dir', load them with 'load' and run them with 'run'. This stuff works.
2023-07-04: connecting up a VGA monitor, I get output. so things are working. Nice. Later - added a PS/2 keyboard, I can type commands. Commands are: help, dir, config, lsblk, readblk, dir, lshw, hexdump, run, loadf, load, screen_clear, screen_bench, screen_fill, screen_mandel, input_kbtest,
2023-07-04: programming the Pico with the Neotron BIOS. I wired up a picopobe to the debug connector in the Pico (SWCLK, GND, SWDIO) and powered on the Neotron. check for the probe
tingo@kg-core1:~/personal/projects/2023/rust/embedded/neotron/Neotron-Pico-BIOS $ probe-run --list-probes the following probes were found: [0]: Picoprobe CMSIS-DAP (VID: 2e8a, PID: 000c, Serial: E660D4A0A71CA332, CmsisDap)

nice.
2023-07-04: bought a 39-1512 27 W power adapter for NOK 199.90 from Clas Ohlson. Max current is 2.25 A, and it can be switched to 12 V. Verified the 12V setting, found a plug with ID 2.1 mm, inserted it and verified that the center pin is positive, and that the voltage is 12 V.
2023-06-13: today I got a pickup message, and in the evening I picked up the package at my local pickup point, Extra Trondheimsveien. I had to pay NOK 275.- in VAT and NOK 149.- in customs fee. So add NOK 424.- to the total price. More tracking info:
13 June 20:31 The shipment has been delivered. 13 June 09:45 - 0506 OSLO The shipment has arrived at Extra Trondheimsveien. 12 June 12:51 - 0024 OSLO The shipment has been sorted and forwarded. 12 June 12:29 - 0024 OSLO The shipment has cleared customs and sent to the recipient.
2023-06-09: the tracking information from the Nrwegian Postal service is interesting:
9 June 08:09 - 1470 LØRENSKOG The shipment being processed for import. 9 June 07:12 - 1470 LØRENSKOG The shipment has been sorted and forwarded. 7 June 23:05 - 1470 LØRENSKOG The shipment has been sorted and forwarded. 7 June 17:27 - 1470 LØRENSKOG The shipment has been sorted and forwarded. 5 June 11:40 - 1470 LØRENSKOG The shipment has been sorted and forwarded. 5 June 10:56 - OSLO LETTER CENTER The shipment has arrived in destination country. 31 May 03:31 The shipment has been sent from origin country. 30 May 12:30 The shipment has been collected.
either they have shipped the package back and forth for four days, or they have done nothing but repeating the same tracking info for four days.
2023-06-03: I need a box for the machine. Buy a Phanteks Enthoo Evolv mATX TG, or make my own?
2023-06-03: I created this page.
2023-05-30: the order was shipped.
2023-05-28: I ordered a Neotron Pico v1.1 Full Kit from theJPster on Tindie. Price was USD 99.- shipping USD 14.- in total USD 113.- which is NOK 1306.75 at current rates.
