We used to use it for our DEC Qbus and VAXBI bisync/SNA protocol emulator boards... very fancy stuff for classic equipment. A few gotchas like you can't access the registers in back-to-back I/O instructions... there's some internal delays especially on the 4Mhz parts when used with an 8Mhz MC68K CPU. I expect that on a 6502, there's no problems, though. Also, the ASDG Serial card for the Amiga used the Z8530 - 6Mhz and 8Mhz versions. -ethan ===== Infinet has been sold.
