Gang: I asked a question regarding what I thought was a software problem in Usenet; now it seems that this might actually be an odd hardware problem in the framebuffer or monitor that I am using with my HP735. I think that I might actually get better advice on this list. I am including the posts below; they appear in reverse chronological order; please start reading at the bottom. carlos. From: cem14(a)cornell.edu (Carlos E. Murillo-Sanchez) Subject: Re: Some fonts fuzzy/blurry in 10.20 CDE apps Date: Wed, 29 Aug 01 11:51:53 GMT Organization: Cornell University Electrical Engineering Oh-oh. You are right, I have just looked at the image in another system and it looks fine. Now, this is _very_ hard to understand: why would some fonts (even some with very small/narrow features) be displayed fine by the CRX24Z and others not? Since thist now seems to a hardware problem, I have cross-posted to comp.sys.hp.hardware. One more clue: when an improperly displayed font is against a light background and you proceed to highlight it such that it becomes white font over black background, it looks fine! But if the highlighting is white over some lighter background (such as yellow in Netscape) the problem remains.

Heurikon (was: RE: Solbourne VME Boards)

by ken＠seefried.com

From: "McFadden, Mike" <mmcfadden(a)cmh.edu> > There used to be a www.heurikon.com page. They are at http://www.artesyncp.com/. They've changed "corporate focus", so support for things like my V532 (NS32532) and Nitro260 (MC68060) are not a priority, although their support folks have really done all they can to help me out. Nice people. Ken

S-100 Power Supplies: thanks!

by ajp166＠bellatlantic.net

Rich, If you need a S100 PS I have one free for picking up. That transformer is far to heavy to ship. FYI this one has the regulators for 8" drives.

Plessey "PDP-11"

by pete＠dunnington.u-net.com

I've acquired a Plessey PDP-11 clone, which has a KDJ11-AC and a bunch of Plessey boards (no other original DEC parts). I was interested in it because it has a full install of RT11 V4.00 and TSX-11, and it has a SCSI (or maybe just SASI) card in it. However, it has no documentation :-( It also has no floppy, just a winchester and an ancient QIC tape drive. Has anyone got any information on the Plessey cards in this machine? Here's the layout: [ DEC KDJ11-AC ] [.....empty.....] [.....empty.....] [ 705919-001 "MIN 1360" 1MB RAM ] [.....empty.....] [ 703755-600E ] [ 703330-100L ] [.....empty.....] [ 703330-100L ] [ 703330-100B ] [.....empty.....] [ 703330-100C ] [.....empty.....] [.....empty.....] [.....empty.....] [.....empty.....] [.....empty.....] [.....empty.....] [.....empty.....] [.....empty.....] [.....empty.....] [.....empty.....] [.....empty.....] [ 705200-300E ] [ 703365-100J ] [.....empty.....] 705919-001 is 1MB DRAM. The board is 1/4 populated, with 36 DRAMs. 703755-600 is a tape controller. It's connected by a 50-way ribbon cable to an Archive Corporation Cartridge Tape Drive, Model 9020L-2. QIC02? QIC36? 703330-100 is a DLV11-J lookalike. Links and switch settings unknown! I could probably work out the address and vector switch settings without too much trouble, since I have four of them set for consecutive addresses, but I don't know about the rest. 705200-300 is a SCSI (SASI?) disk controller. It appears to emulate an RLV21 with 4 x RL02, and has a Wren-2 43MB drive on it. It has a couple of PROMs, one labeled "UK5" and the other "335-100A". 703365-100 has a serial line for the console terminal, connections to the front panel switches, terminators, a bootstrap (?) made up of 4 x TBP28L22 PROMs, three 8-pole DIL switches and several wire-wrap posts. Any info/docs welcome, as would be formatting software (or instructions, if it's built in) for the disk controller... -- Pete Peter Turnbull Network Manager University of York

Altair documentation

by mranalog＠home.com

Hi, Does anyone know how to contact Steve Shepard in Albuquerque? Has anyone talked to him lately or know if he still sell copies of Altair manuals? It's been a couple of years since I talked to him and I don't think I ever did have his email address.

Corvus OmniNet Protocol???

by aek＠spies.com

The basic transporter was a Motorola synchronous serial interface chip, a 68xx microcontroller, and a Corvus ASIC. NEC built an integrated device for them later. The service manuals for some of the early peripheral controllers described it in detail, unfortunately the only person that still has that information is Eric Lander, and I have no good contact info for him any more. The Macintosh version of the Constellation software just used the SCC I assume in HDLC mode.

Solbourne VME Boards

by mmcfadden＠cmh.edu

Several types of Heurikon boards are listed in the VME bus FAQ. About 1988 we used to build Heurikon based Unix systems for medical image processing. We used the Multibus variety not VME. 400MB Fujitsu eagles 800/1600 bpi Kennedy tape drives 40MB QIC tape drives Hyperchannel Network RAMTEK color monitor 512X512 Megascan BW Monitor 2500 X 2000 Later we added 12" LMSI WORM drives Each image was 10MB and I put 4 per tape. There used to be a www.heurikon.com page. Mike mmcfadden@com

Opening a Z-19: Thanks!

by r_beaudry＠hotmail.com

Hello all, Thanks to those who answered my inquiry on opening a Z-19. You were spot on, and the case opened quite easily! There were no physical signs of damage, so I replaced the cut-off power cord, and fired it up. Unfortunately, the same problem as my Osborne I -- no CRT glow from the neck, and nothing on the screen. Twiddling the brightness did nothing. Oh well, one more thing to fix. I did pull it from a dumpster, so what can I expect, right? :-) I'm not going to ask for docs or information at this time, as I have two other major projects to dive into (the Northstar and the Osborne). When those are done, I will revisit the Z-19. Thanks again to all who helped me "crack the case" :-) hahahahhaha Rich B.
