The buss speed of the original Wallstreet series is determined by the
processor card. The 250 and 292 processor card should work even in the
233Mhz cacheless model where they will bump the buss speed of the MB from 66
to 83Mhz. The cards are sold as an upgrade for the 233 cacheless model by
PowerBooks Parts. All of the processor cards from the second generation
Wallstreet will work in all the first generation Wallstreets, where they
will slow the MB speed of the 250 and 292Mhz units down to 66Mhz. But only
the 233Mhz cacheless processor card from the first generation Wallstreet can
be used in the second generation Wallstreet, which can only be ran at a
66Mhz buss speed.

The first generation Wallstreet was available with a 12" passive matrix LCD
with both the cacheless 233, and the 250Mhz model. The units with the 12"
Passive Matrix LCD came with only 2 Meg VRAM. The 13.3" and 14.1" screen
came with 4 Meg VRAM and were available with all processor speed options.
Models with the 12" passive matrix screen also lacked an S-Video port.
