 The DEC Rainbow could (officially) take 896K of RAM
(128K on the
motherboard and a memory expanison card with 3 banks of 256K chips). The
oriiginal Apricot could be pushed to 960K -- actually, there was 1Mbytes
worth of chips on the board but the last 64K was taken up with the
boot/BIOS ROM and the video memory. 
A minor nit: my Rainbow 100A model has only 64K motherboard and 768k on the
memory card (atop the 8087/8088 daughterboard), for a total of 832K. I
think that's maxed out for an A model. What Tony says is correct for B or +
Rainbows, AFAIK. Anyway that's yet one more number on the "max. mem" plot
for 808(8,6) machines.
