HP 2000 TSB question

by west＠tseinc.com

I finally finished testing out all the memory boards in my two HP2100's. I was getting misleading results for a long time due to my lack of understanding of the way the memory subsystem operates - it has to be tested in a very specific non-intuitive (and undocumented) way. Turns out I have four bad boards; three 8K SSA core stacks and one 16K ID board. These two systems ran HP2000 Access TSB, and had 32K each. My question is (before I spend time hunting down replacement boards) does anyone know what the memory requirements for the main and IOP cpu's in 2000Access is? If I can get by with less than 32K in each cpu I can forgo getting replacement boards for the time being and perhaps run with 24/16. Any ideas? Jay West

Can someone here telnet to my 11/35

by dylanb＠sympatico.ca

Thanks everyone for telnetting into the 11/35. It seems the 11/35 could handle the guests but not my PII-350 :-(. The terminal server is now repaired and it looks to be stable. .. though probably not as stable as the 11/35. I will be putting online many different PDP-11s/PDP-8s online throughout this week and the coming months. The 11/35 will have FORTRAN IV, MACRO and FOCAL added to it (with a lot more games) later on today. http://www.pdp8.com/telnet.htm Enjoy! PDP-8 and other rare mini computers http://www.pdp8.com

The BIOS on this particular box seems to see it as the slave device on the IDE interface if there is a real IDE drive installed on the 44-pin connector. The problem with this box is that there is no way to import software since the SanDisk is soldered on, not plugged in, like some embedded designs. What appears to be necessary is to install an alternate OS on a laptop drive that is installed in a _real_ machine, then stick the drive on this closed box. > However, I'm wondering if there is a way to also use it as a Serial > terminal. There does not appear to be an RS-232 port, but I have two options - one quick-n-dirty, the other only theoretically possible. First, I have a box that simulates a CO. I can stick a modem on the other side of this thing and use its internal modem at 33.6 (maximum speed without a digitally- enhanced ISP on the other end) or down to 9600, say, and simulate a dial-up connection with whatever software is handy - I'm fond of Kermit myself. Alternately, it may be possible to remove the modem and add a MAX-232-based level converter and run a cable outside the case for "real" serial devices. I plan to inspect the innards and hang a scope off of whatever interconnects there are. Worst case, the UART is embedded in the modem and I'll have to be more creative by probably installing a 16550 on a daughter card in place of the modem. I don't know if I'll go to that extreme. > Do USB drivers for DOS exist?

Agreed, but I may stick a Linux Router Project kernel on the internal SanDisk and mount stuff via NFS - slow over the parallel port, but it should work once I get an adapter. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

I'd assume that it's the same at CC; you probably buy the > box there for $99 + tax without the internet service. OK... here's the scoop... my local CC is backordered over a dozen units. I put down a $20 deposit on one and it is supposed to arrive in two weeks. The way the billing works is you pay $99 + tax for the unit and as soon as you connect it to a phone line and give it the go-ahead, the unit connects with the central office somewhere and you enter in credit card info and pick yout billing plan. If you never connect it to a phone line with the default QNX software, you never have to worry about signing up. I expect this policy to change when they see hundreds if not thousands of units sold with no service started on them. Until then, I've (almost) got mine. Now all I need is a DE-620. -ethan ===== Even though my old e-mail address is no longer going to vanish, please note my new public address: erd(a)iname.com The original webpage address is still going away.

What about the USB port? It seems like they are not using it in the iopener configuration but is it available to other OS's? If it is then eveything and more can be hooked up: scanner, CD Writer, floppy, mices, printers, joysticks etc... lokk pretty good for the bucks. I'm making a stop on the way home tonight. Now what is a good source of 2.5" HD's. How about the SanDisk is that a port or is it soldered on board?

Red Erasors

by edick＠idcomm.com

The eraser I always saw recommended was a "pink pearl" which was in commonly available supply at any office supply store. I never bought into the notion that the substance I was removing was "corrosion" for the simple reason that the backplane connectors and the PCB's were gold-plated. Since the eraser always left a clean gold plated edge connector, I quickly concluded it was dirt and not corrosion that was accumulating at the interface between PCB and backplane. I found much less of this occurring in clean environments where dust didn't accumulate in the equipment cabinets, so I did what I thought necessary to exclude dust from all the cabinetry, and, guess what! ... There was much less "corrosion" in the cleaner boxes than in the dirty ones. Dust doesn't cause corrosion, does it? It could cause abrasion, but I doubt that's at the root of these problems. My question would have to be, "How do you clean the backplane connectors?
