[cctalk] Re: Current SOA scsi disk emulators for DEC

I'm currently using a version 5 something (5.4 I think) of the SCSI2SD in my 11/83 to run 2.11BSD, it has worked well.

[cctalk] Gb Ethernet and 10Mb links

FYI: The Ethernet standards dropped support for half duplex connections a few years back, so that if you have something that depends on half duplex links a recent Ethernet switch might not support it.

[cctalk] double cctalk membership

I followed the suggestion in a previous message to logon to the new server and set my desired list settings. Now I show up with two subscriptions for my email address, one as "nonmember" and the new one as "member". It does not appear that I am receiving doubles delivery of messages, so I'm not

Not just slashed zeroes/ohs

Having gone through many mathematics courses it was common to also place a slash on the letter Z to distinguish it from the numeral 2. Also for persons from Europe where they slashed the numeral 7 to distinguish it from a numeral 1 that commonly had an initial small upward stroke at the top

Re: P112 Floppy Controller

The P112's floppy controller is the one in the SMSC FDC37C665IR SuperIO chip. The data sheet states it is a 2.88 MB "Licensed CMOS 765B Floppy Disk Controller" and claims 100% IBM compatibility (for what that's worth).

Re: External SCSI Drives on DEC2000 AXP

Have you verified that the SCSI bus is terminated properly? A missing or improperly configured terminator can sometimes cause those sort of symptoms.

I've also used a version 5.1 SCSI2SD on a VAXstation 4000/60 without problem.

Microfiche reader spotted in Longmont, CO thrift store

If anyone along the northern Colorado Front Range is in need of a microfiche reader, it was reported to me that a Micro Design model 4010 is sitting in the Longmont Community Thrift store. My source didn't notice a price. The condition is unknown, but it appears to be reasonably intact, and a

The PROM in my 9114B committed suicide this morning, letting the magic smoke out. It was marked with part number 09114-15521, does anyone happen to have dumped the contents so I can program a new one? Thanks.

Re: Replacing cables sheaths?

Thanks for the suggestions. I currently have Rescue Tape brand self adhesive silicone tape on the cable, but it looks like it is causing corrosion of the spiral-wound metal shield wires. The wrap around heat shrink might cost more than just buying a new adapter! It looks like there is an 1/8"

Replacing cables sheaths?

Does anyone know of an effective technique to replace the sheath of a cable without needing to reterminate the ends? On all of the Apple power adapter cables I've used the plastic sheath starts to fall apart, but the adapter itself and the cable conductors are still useable. Something that

Just bought an Extron RGB-HDMI 300 (A) that handles VGA and other RGB type signals and has HDMI output. I've connected it to my VAXstation 4000/60 (very successfully), and my IIgs (reasonable but this is at the low end of what the unit can manage). Output on either my Sony 46" TV or Apple

Re: P112

Just in case someone else hasn't already responded, the P112 does not use DOS style fdisk partitioning for a hard disk. It is done in the BIOS image, and then the logical disks have to be initialized. This is described in the "P112 GIDE Construction.pdf" document. I've only used 3.5" floppies,

Re: Raised Floors

I should have been more clear in my last response. The 2x2 grid of the floor tiles does not extend to the floor, but to an intermediate layer with wider spacing of the supports at the floor level.

Re: Raised Floors

The NCAR Wyoming Supercomputer Center has raised floors of about 20 feet. The auxilary cooling and PDUs are installed down there. Needless to say, you don't pull a floor tile there unless you are on the facility staff!

Re: DEC 3000 (alpha) faultfinding

On the AXPpci33 board, the SROM is also an 8 bit device. What happens is that the CPU reads in a bit stream into cache at power up reset, where the specific bit stream is selected by the jumper position on the board. In effect the SROM can contain up to 8 bit streams. Some of them will make use
