Emulex SC03 disk capacity patch manual scanned

by Christopher Zach

Hi all! I noticed that while the Emulex SC03-B1 manual is on Bitsavers, the instructions for how to patch and use this board on a 22 bit Q Bus system are not. In the manual it says to "Write emulex". Fortunately I did 40 years ago and I have the "Emulex Disk Capacity Patches to DEC PDP-11 Operating Systems" manual which is now scanned and online at https://www.crystel.com/dec/sc03 Emulex document ID is PD9951002 Rev A, March 1983. Covers Rsx11M 3.2, 4.0, RSTS/E, and M+ versions at that time. Every page is scanned as a 300 DPI TIFF image, and there is a PDF version of the whole manual as well. Apparently they use the RH70 Unibus driver (which supports 22 bit without the unibus map) and then change a few bits to make it work on Q Bus. Enjoy and bitsavers owner please stick this in your archives as well. Chris

Re: vintage computing web sites

by donald donaldwhittemore.com

In the early 70s I worked at a place that had 2 S360/40s. On the 23rd floor of a 45+ year old building. At least 8 tape drives, 2 control units for them, 2 full banks of 2314, 2 1403 printers and 2 2540 card machines. I would assume updated wiring would have to have been run up 23 floors. When I started there was 1 S360/30. Don’t know if the normal building wiring would need to be updated for that.

I, for one, have fond memories of the S/360-20, 30 and 40. I ‘grew’ up running and programming those systems. FWIW, I have a punch card archive at www.ibmjunkman.com

by Bill Degnan

Does anyone have, or has even seen, a Computer Data Systems "Versatile 2" s-100 computer from 1977? The company that produced it was from Newark, Delaware USA and I have been trying to track one down because I live nearby. Thanks Bill

Esprit Opus 220 serial terminal

by Holm Tiffe

Hi there, at the beginning of the 90ies I've repaired some Esprit Opus220 terminals for an local computer shop. Problem #1 of those seriaal terminals was a bad the Flyback Transformer. The Shop managed to get a bunch of those FBT's new from Taiwan so I could successfully repair approx 10 of those terminals. I'm still own one of them, still in functional condition (orange 12 or 14" CRT).. My stash of goods should still contain two of those Replacement FBT's, but after a move in 2020 I have to locate them.. So far so good. Now the Problem: I have an Grundig CD313 monitor from an CNC EDM Machine on the table, the FBT Grundig 29200-003.05 is bad and I want to repair the monitor for the small company owning that machine. Unfortunaltely they are located some miles away from me.. My hope is to locate the two new FBTs and adapt one of them into the Grundig CD313 Monitor..where I have the schematics for. It where pretty nice if I could get the schematics from one of that Esprit Opus II (220) Terminals to look at the wiring for the FBT ..and that's my problem.. has anyone the scheamtics for those Opus terminals?

Any Interacts out there? 1978, 8080-based system

by Steve Lewis

Checking on if anyone has an old Interact system out there. It wasn't widely successful, but gained some popularity around Ann Arbor, MI. I've not come across one of these yet. But I've come across one of its "Killer Application", a tape-based program called Message Center that lets users construct banner message scripts with a few video/audio effects. Would be interested to see this "for real" rather than just in the MAME emulator. Or also to hear any stories about the system, such as anyone who actually used one, or saw one being used at a storefront? -Steve
