Hans Oranje "MiniMapper" HELP

Hi,

I want to make the 1Mb MiniMapper from the hansoranje.nl website.
Is there anyone that made it already, or is there someone that can help me, because I'm a but confused about the schematic.

Do I make this onto a cartridge print, and put it into a free slot... or do I have to put it inside my Sony HB-F700P ??
If I look at the wiring of the schematic, most of them are similar to the MSX slot pinout, but not all pins are there. For example the MUX, MA18 and DOC-P6 wires are not in the pinout of the MSX slot. Where do these go ??

I tried emailing Mr. Oranje, but he doesn't respond unfortunately.

Many thanks in advance !

i make this schematic in a VG8235 but never on HB700
look schematic for philips 8245 on Oranje site for more MUX and DOC-P6 info
the MA18 is just internal signal , the mapper use L8 L9 for SIMM

the MUX is on Philips only , in the HB700 the signal is MPX pin 41 of S1985 and pin 1 of IC 17 and IC 22 ( 74LS157 )

Thank you for your info.

I think I'll play it safe and try to build an external Memory Mapper instead.
I found this link that uses an old PC SIMM. It seems simple to make, if I can find all the parts I need...

Merci beaucoup for the schematic Jipe !!
I will definitly try to make it in my HB-F700, but I'll try to make the external memory mapper aswell, just to test if it works.

Again... many thanks, I'll let you know if it works (or not).
Merci !!
