- Hello Steve,
-
- perhaps ou understood something wrong, but the normal 53C80 is the SCSI-chip without 8530 in
- the TT but you are right, that there are circutes, which have implemented the 8530.
-
- But there's a much easier solution. Someone in our MausNet pointed out, that there is
- a newer 85230 which is also pin- and soft-compatable and have more buffer than the normal
- one. As I can remember it was something above 6 bytes.
- And now AMD, too, offeres a even newer version of the 8530 which will have even more buffer,
- but I've no more informations about this chip.
