HP 2000 TSB simulated?? YES! 2000 E, and F and Access have all be en running.

by MGemeny＠pgcps.org

Hi folks, Well, the haunted house season is over and the cleanup continues. Now I'll have more time to put into the HP2000 simulation project. As you may remember we did get HP2000 Access running under simulation, as well as "E" and "F". But so far no one is running a system full time. I was running the system under Windows, but Unix and Mac are supported as well. We have most all of the documentation including the source for Access date code 1812, and should have most all of the contributed libraries. Would any of you have access to other HIBE tapes? Ether in your archives or in archives of data centers you used to support? We still have more HIBE tapes that need to be converted to CD ROM and lots of work sorting it all. It sure was nice the first time I launched a telnet to my windows box and got the "PLEASE LOG IN" prompt, and it was even better once I has able to log in and play Adventure. Since the simulation is faithful to the hardware, the original operating system binaries don't even know that they are not running on real hardware. I even have to use an image of the actual 2100 paper-tape bootstrap program to get Access running under simulation. With this approach to the simulation, every feature, flaw (if there were any), or quirk is faithfully reproduced. I'm trying to get HP to allow a hobby use open license, but until then the package is available only on an as needed basis. Do you know anybody who may want to play sysop and keep a system running for the public to play with? If so, just drop me a note. Mgemeny(a)pgcps.org Ps. We also did a paper on the project, which can be found here: http://descanso.jpl.nasa.gov/RCSGSO/Proceedings/Paper/A0053Paper.pdf <http://descanso.jpl.nasa.gov/RCSGSO/Proceedings/Paper/A0053Paper.pdf> Thanks in advance, Mike.

Probably not at Home Depot, but specialist hardware suppliers (any rack supplier) will have them, or Tinnerman Palnut themselves. Try a Google search for "tinnerman" :-) Or see if any local suplus places have any (look for them still attached to racks). You'll find that using ordinary nuts and bolts is often very difficult, because you often can't get your fingers in to hold the nut. > I've got part of the original rails :).

Correct, there are usually three (or four) screws at the front, and the same at the back. If you've got two parts of the rail, one sliding over the other, you're just missing the back brackets. If you've got only one part, fixed to the side of the drive, you have slightly less than half the rail (you're missing the larger part, with all the ball bearings, and missing the back bracket). The back brackets are plated steel channel, about 8" long, that fit over the stationary part of the rail. The end is bent over into a flange that bolts to the inside of the rack's vertical member. I dare say you could make something that would do the job. -- Pete Peter Turnbull Network Manager University of York

Grandfather system RTE6/VM?

by aek＠spies.com

I think Al said he might have found some reference that proves that the IOP firmware was actually ported by HP to the E. Can you confirm? -- The part numbers for the E version appear in the 2000 section of the M/E/F CE manual. It has 6 proms listed instead of 12. I still think it's possible to convert the MX version to the E. Bob and Mike figured out what the instructions do (from memory something like cnvrt isn't even used..)

HP 2000 TSB simulated?? YES! 2000 E, and F and Access have all been running.

My computer is up and running 24 hours. I have some particular interest to play with the HP2000, and sould like to get the package to put it online (and play with too).

How does one use the Museum page? Also, how does one find information on a computer that one is looking for? What is a WIKI? On your page, you mention that one should be willing to pick up any machine that is offered. While this is a nice thought, I couldn't even justify the price of gas to pick up a no name 286 PC. I don't know anyone that would pay shipping on such a machine. I would cost me extra to bring it to the land fill transfer station that I go to because these are considered hazardous waste. Under these conditions, I don't think I could consider myself a curator for your page although I would otherwise love to post my collection. Dwight

Stacking two 9 volt alkaline batteries should be enough to make the unit operate properly, giving 18 volts. If you find a problem here, you can always cut open a 9 volt alkaline battery and remove enough cells to make up the 4.5 volts. The alkaline units have separate cells that can be individually removed. This is unlike the stacks that are used in 9 volt carbon-zinc batteries. Be careful to leave enough welled strip to solder to so you don't over heat the cells. Later Dwight

Burgess XX15 Battery Specs?

by classiccmp＠earthlink.net

I have an old Triplett 631 VTVM/VOM (that I use with classic computer stuff, of course) that uses a Burgess XX15 battery. The XX15 is 22.5V and is no longer made. There is a "fix" for this situation posted on the Web that substitutes several currently made 22.5V batteries. But, I'd like to see if there are any other ways of replacing the XX15s. So, does anyone have an old spec sheet for the Burgess XX15? I couldn't find anything on the Web. Thanks, Dave

Another TRS-80 OS

by alhartman＠yahoo.com

There was Multi-DOS by Vernon Hester, it worked on Model I/III/IV He also made a simple version called V-DOS (I think) for Game manufacturers. Percom also had Double-DOS There were quite a few more, Percom had it's own incompatible DOS for awhile also. And then there were the various CP/M flavors for the TRS-80 like Lifeboat, Lobo, and others. Al __________________________________ Do you Yahoo!? Protect your identity with Yahoo!
