Apple II

I've recently restored this Apple II+ Clone. It has a UM2316 as character ROM. The Chip itself is replaceable with a 2716 eprom. But none of the standard Apple II Character ROMs works.

The connection between the ROM and the 74166 totally diffrent from what it is in a regular II+.

Does anyone regognize this board? Are there any Informations / ROM images available anywhere?

Hello. I am newly to join this forum. 

I have Apple II plus (Rev.4) which I bought I was high school student(38 years ago!).

I kept it for a long time and draw out to share the excellent machine with my son.

I've found various ones for the II-II+ models where the encoder is on the keyboard it's self, but none for the ][e or //e models with the AY-5-3600 on the motherboard.

I've got it in my head I could roll my own with a small Arduino (Nano maybe...) but I detest reinventing the wheel, so I thought I'd ask you folks if it's out there and I (or Google) has simply missed it.

I'm new around these parts, so why no start with an odd question? I've got a crazy idea but I need to know if the //e mobo will fit.  I figure a bunch of you probably have nekkid motherboards around and could dash off two measurments for me.  So would you kindly?

TIA.
