====== DSKY ======

//PCB is marked with “v3” but it seems like this is in fact the same as v2. I just uploaded the gerbers directly to JLCPCB without any modification.//

DSKY keyboard/display unit to be used with the SBC v2 or v3.

I used SBC v003A (it needs a 26 pins par connector not IDE)

Its powered by pin 25 on the par port via K9[2-3] on the SBC.

K1 on the DSKY need to be jumpered [2-3] to get power from pin 25.

Set PC-terminal (I used Tera Term and a USB to serial adapter) to 9600 baud 8N1 and no flow, VT100 is okey, see pictures below for furter details.

Boot options:

DSKY button “BO” + “0” = Boots to Serial monitor

DSKY button “BO” + “1” = Boots to CP/M v2.2. Look in drive F: and G: for some tools.

Not sure about the key labeling on this version of the DSKY PCB vs the pdf manual…?

(I have some extra pcbs in Norway if anyone interested)
