RE: [N8VEM-S100:2139] Happy New Year to all

Not sure about the 8088 Fabio, it’s Andrew’s call.  Actually the 8 bit VGA should work perfectly fine (and fast) with the future 80486 S100 board. That’s because the 80486 has 8, 16 and 32 bit data bus capability.   This is not the case for the 8086, 80286 or unfortunately 80386.   However I’m not recommending most users start with an 80486 board. It’s going to be complex, best to start with the 8088.  That board is now very reliable and fine-tuned.

Ok, apparently I just found out where my next paycheck is going to be spent :-)
I'm putting myself in line, if possible, for a Z80 v2, SMB, 286, 386, 16MB exp and probably the VGA board (I'm pretty sure I have the TVGA9000 chip in one or two ISA cards around home...).
The interest in the VGA board depends on respin for the 8088 CPU card. Any plans on that?
