the venerable 80186 (and 80188)

by feldman.r＠comcast.net

The HP 100LX/200LX/1000CX/OG700LX use the "Hornet" chip, which contains an 80C186 along with I/O, display and other modules. There is info on this chip (block diagram, pinout) at http://www.daniel-hertrich.de/en/knowledgebase/hplx/hornet ?

Help restoring early issues of Mark-8 Newsletter

by lausadel＠gmail.com

Hi. Just wondering if you ever figured out how to chemically lift images from faded dittos. I have the same problem with a personal document that you did with the Mark-8 Newsletter. Thanks. --Dawn Lausa

VAX 11/750 2.5V supply problems

by david_comley＠yahoo.com

I have been trying for some time to repair the 2.5V supply on an 11/750, without success. The symptoms are loud squealing which changes back and forth in pitch (in fact it sounds a bit like RTTY, only over a couple of pitches), OVERCURRENT and REG FAIL indicators on the status panel on the back of the machine. All the boards are pulled from the backplane and I?m using dummy loads on the supply. There?s no evidence of shorts on the chassis or on any of the supply outputs. I?m testing with the voltage sense wiring in place. The output electrolytics have been replaced on the 2 regulator boards and the big electrolytics on the primary side check out OK. I?ve measured 300V DC across the switching transistors on the primary side. I?ve not detected any problems with the electrolytics on the 30V supply and 2.5V supply but I have ordered replacements just to be on the safe side. I?ve checked over all the diodes and transistors with the Huntron tracker with no obvious evidence of any failures. So far all I?ve really been able to establish is that there?s no output on the ?secondary? side of the supply, that is, the 30V supply which drives the +/-5VB and 12V regulators, and the 2.5V main output of the supply. I think the REG FAIL lamp is a red herring because without the 30V supply active, REG FAIL would have to be lit if I understand the schematic correctly. I?m posting on the off-chance that someone has had this problem and has dealt with it. I?ve been looking at this on and off since July but haven?t made any headway. Thanks for any suggestions the group may be able to offer. By the way, the story of the machine and work done to date is at http://comley.us/browse.php?&action=show&artefactID=1051 -Dave

Data General software agreement pre-announcement (Merry Christmas)

by bruce＠Wild-Hare.com

Data General legacy preservation fans - After 9+ years of negotiations, Wild Hare has secured an agreement with Data General to recover, archive and release Data General 16-bit and some 32-bit software for educational and non-commercial purposes. A official announcement will be made next month, but I wanted to let list members know that sometimes good things can happen. A special thanks is extended to the amazing William Donzelli, and to the quick-footed Carl Friend, who made the physical tape rescue in Massachusetts possible. Thanks also to the legal and technical folk at EMC (Data General) who finally made this a legal reality - and who might prefer annonymity at this point. Details will be posted in a few weeks, but I wanted to share this bit of Merry Christmas for DG fans.
