Last year, I discussed the idea of a packet-assembler-disassembler on rec.ham-radio.packet (now rec.radio.amateur.packet) which uses a SCSI link to the host. This is a project I've had on the back burner since then, mostly 'cause I wasn't looking very hard for data on SCSI interface chips. Now, while perusing some Zilog literature, I discover they offer a chip which combines the Z85C30 SCC (ubiquitous in packet radio) and the Z53C80 SCSI. The Z85C30 SCC is a very well known quantity; however I know nearly nothing about the Z53C80. Are there any readers who have used either the Z85C80 SCSCI (the combo) or the Z53C80 SCSI? I'd like to know about this SCSI controller, particularly any difficulties with the part or availability. Thanks, Dana -- * Dana H.

I'm almost sure (99.9%) that the Z53C80 is the same as a very well known NCR SCSI chip - 5380. It's a _standard_ SCSI device and quite well behaved. One thought - both chips come in 40 pin cases, so the combination might be hard to use: I mean PGA is not very nice for home projects. -- |--------------------------------------------------------------------------- | -Alex Freed (The opinions expressed are my own. | However everyone is entitled to them.) -- |--------------------------------------------------------------------------- | -Alex Freed (The opinions expressed are my own. | However everyone is entitled to them.)
