Re: OT? Upper limits of FSB

Interconnects at 28Gb/s/lane have been out for a while now, supported by quite a few chips. 56Gb/s PAM4 is around the corner, and we run 100Gb/s in the lab right now. Just sayin’ ;-). That said, we throw in about every equalization trick we know of, PCB materials are getting quite exotic and

ISO - 386 or 486 system or cplt mobo

I'm interested in finding a 386 or slow 486 machine or moboj ust for playing DOS games. Does anyone have such a thing sitting around, looking for a home? Thanks in advance.

Hi Jake, I don't have a UC04, but its manual states its  Peripheral Interface is SCSI single ended.  The pinout is just like the UC07, except for terminator power.     Jerry On 1/5/19 4:46 PM, Jacob Ritorto via cctalk wrote: Hey all, Anyone know whether the Emulex UC04 works with the

The copy of the KD11-EA engineering drawings (in the 11/34A Field Maintenance Print Set, MP-00190) on Bitsavers is missing most of the pages that hold the microcode flow diagrams. I have a set of the KD11-EA FMPS (MP-00192), which does have all the missing pages, which I can eventually scan.

Hey all, Anyone know whether the Emulex UC04 works with the sd2scsi? I just bought a uc04 and it won't talk to any of my old scsi disks, seems to think there's supposed to be a "controller" in between :\ yuck. thx jake P.S. While I'm at it, anyone know how to get UC04 to talk to directly to

I'll assume you've read: https://en.wikipedia.org/wiki/Front-side_bus Even though synchronization base clocks have remained low, parallel buses can run up in the low GHz range (sub 4) in terms of data line transitions per second with as many as 128 parallel wires in sync. It's not just
