Just a wild guess, but if you have an HP 35731A monochrome monitor, try it with that. That wants composite video but with a horizontal frequency of 30KHz instead of the more usual 15KHz. HP used that on several different systems. There may also be a jumper on the video card to select the horizontal frequency, but the only thing I ever saw this on was the HP Multimode Display Adapter for the Vectra (sort of a combination of the IBM MDA and CGA that was good for confusing "smart" software). -Frank McConnell

There are copy machines that can optically adjust the image distortion that takes place as the page curves away from the scanning bed? Cool! We don't have them around here, tho... libraries around here are lucky to be able to keep the electricity on... -dq

PDP-8/E questions

White leds are a bit blue rich though they would work. One point is that there are some 28 or so leds/lamps and good ones will not be cheap and cleap ones will not be good. Allison

FS/FT: PDP core memory boards

by mrbill＠mrbill.net

I've got two of these: (from the Field Guide): H215 Unibus 8-Kword 18-bit (parity) H213 (used in MM11-LP, ME15) in what looks to be great (for their age) condition. I dont have a box to test them out in, however. Would like to trade for 10baseT ethernet switches, especially Kalpana or Cisco. Bill -- Bill Bradford mrbill(a)mrbill.net Austin, TX

Northstar Horizons Possibly Available

by ajp166＠bellatlantic.net

I have two already, not adoption here. But if you need info... Basic machine is S100 Z80/4mhz, if ut ran NS* dos no memory below 2000h so usual config there is 48 maybe 52k. If it's running CPM then ram from 0000 to E800 and continues at F000 to FFFFh. Two serial ports, One parallel that can be centronics compatable as an option. FDC is raw TTL, runs hard sector 10 per track and if the later controller is installed double density at 10 sectors by 512bytes with up to 80 tracks and two sides (800k). The older single density controller was 10 sctors by 256 by 35/40 tracks single sided(80/100k) . Media is getting hard to find but is reliable. An easy machine to get and keep running. Most common upgrade was memory and a softsector controller.

Hi Gang: I just completed grad school yesterday, and as such am hoping to be back into classiccmp more regularly! I noted this afternoon that there are 2 Northstar "Horizons" possibly available on campus. I'm not into these S-100 (IIRC) beasts but others may be. Can anyone tell me something about them? Anybody interested in adopting them? They're in poor to fair shape, but look like one could get them going again without too much trouble. Kevin -- Kevin McQuiggin VE7ZD mcquiggi(a)sfu.ca

[Fwd: RA90: What's error E0 and 7C (and others)?]

by gunther＠aurora.regenstrief.org

Hi, please, someone with an RA90 service manual (Joop?) can you give me a list of the error codes? Or is the RA9x service manual scanned somewhere? I have tested out my two SA600 racks' worth of RA90 drives and found that 7 out of 16 have some problem. They all had a problem with their fans not spinning up at first, but after a couple of attempts this seems like not a big problem. There is only one that's really dead (drive, not power supply) in that the green LED at the rear (on the power supply) lights up only dim and nothing will come up at the front at all. This is same with a different PSU swapped on, so it's the drive, not the PSU. Not quite sure what to do with that one. But 4 or so of them fail only when trying to spin them up and return an error code 7C. It sounds like they do spin up but when trying to seek the fist time they immediately determine they failed. OTOH, in at least one case just retrying it a couple of times will eventually bring it up and running. Another 2 of them fail earlier when trying to spin up. They come up with erorr E0 pretty much as soon as it's trying to spin up. Yet another one comes up with various errors even before spinning up, and one more seems to work but somewhere down the road may or may not fail with various errors. 54 is one I can remember, but there were all kinds of numbers, none of which mentioned in the RA9x user manual. thanks for your generous advice, -Gunther PS: But I do have one full SA600 rack with working drives and boy, it's pretty impressive firing this up. So many buttons to push and lights to monitor, it's fun. One drive contains VMS 7.2 and I'm sure lots of goodies, but I will not back those up. Once I've switched to UNIX I can try RAID with them :-). Does anybody know if the HSC90 by itself does RAID given a disk array and the proper configuration? -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org -- Gunther Schadow, M.D., Ph.D. gschadow(a)regenstrief.org Medical Information Scientist Regenstrief Institute for Health Care Adjunct Assistant Professor Indiana University School of Medicine tel:1(317)630-7960 http://aurora.regenstrief.org
