# a few small corrections
I uploaded new versions of the component overview drawing and the ZX81+38 BOM.
The drawing has the position of the crystal, and the 15pF capacitors corrected, and the Value of RP1 corrected from 1K to 10K (1K probably works, but both the schematic the BOM uses 10K, as does the original ZX-81.
The BOM only has the correction that the 3.5mm jacks are not CLIFF FT6320 (that is the wrong model), but the cheaper FC68131.

The BOM only has the correction that the 3.5mm jacks are not CLIFF FT6320 (that is the wrong model), but the cheaper FC68131, that doesn't have swithces and the correct pin arrangement.
By the way the BOM is in the open source open office .ODS format, which can be opened with the free open office software, or an online tool.and probably also with Microsofts spreadsheet tool if you choose to open a .ODS file with it. I prefer open source formats..
