2021-08-01: I re-created this page on my self-hosted web server.
2019-03-15: projects - possible - icestick_6502 - small 6502 system.
2018-08-04: projects - possible - miniatom is designed for a iCE40 HX8K fpga. The LP8K has fewer I/O pins (178) than the HX8K (206), and only one PLL (HX8K PLL = 2) otherwise they look much alike. Anyway, there are only 23 user I/O pins available on the TinyFPGA B2.
2018-07-11: the TinyFPGA Computer Project Board (currently out of stock) is interesting. KiCAD schematics and so on in Github repo.
2018-03-27: perhaps I could run the PDP8-SOC on this board? Note: no source in repository.
2017-12-04: the TinyFPGA B2 arrived, directly into my mailbox.
2017-11-27: There was a sale on Tindie, so I ordered one TinyFPGA B2 without pins for USD 34.20 + shipping USD 5.- (USD 39.20 in total). About NOK 333.-
