Original PCB from Rodney Knaap. (1998)


(Note: Straps are added on the front side, originally designed on a single side PCB)

Old Gerber PCB (No mask screen on it):

Include skinscreen, but can be removed for fun...

Hi,

Have a look to the rebuiled ZX97 lite from Danjovic (c)2019.

ERRATUM:

The 2N3904 (T1) transistor seen (is) upside down in the video pictures generator.

Emetter (1) is to the up and the collector (3) it to the down side.

In fact, a NPN transistor can work in EBC or CBE, but its specifications may be corrupt by this mistake.
