Note: The handshake/timing used in the above games seems to be less stable than in the Z80 PIO version (seem to be working only if the PC software disables interrupts during transfer - unless the hardware includes automatic handshaking, which isn't seen in the Z80 disassemblies), so the four games may have been using an ''older'' PDS version (or a third-party remake).

Note that the photos seem to be are showing a spanish remake, not the origial hardware (as indicated by the "P DE FRANCISCO" text on the solder side). The two schematics are a "remake-of-PCBs on the-remake" photos are dated around late eighties (ie. the PCBs seem be authentic old hardware, the latest newest YYWW year/week datestamp seen on the chips is from week 01 of year 1989). Andy confirmed that the photos aren't showing his cards. The schematics were drawn at a later time, when reverse engineering how those remake PCBs worked), so the schematics are a "remake-of-the-remake".
