From "Electronic Design", 93/7/22, p102
Toshiba America Electronic Components, Irvine CA, USA
announces the "Tigershark" R4000 - i486 bus interface
chipset. Signals on the R4000 (doesn't say whether PC
or SC versions) "Sysadd and Syscmd buses are converted
to a 32-bit local bus that's compatible with the 486 bus."
Two 160 lead pqfp packages. Includes a secondary cache
controller for 64-1024KByte of external cache. Sounds
like it's intended for the r4kpc variant (low-cost is
part of their target).
US$65, 1k qty per set.

ATI is selling their Mach32 PCI bus chips. Of course, we don't
have PCI on the option list yet. It's the 68800ax. But
a Mach32 would be a reasonable graphics controller.
US$55, 1k qty

Giving up that r3081 stuff, and joining the r4kpc push...
