Re: RSTS emulation in a browser
To answer your question, yes, yuo can down a compacted file or another and it will be able to run locally (done that but not tried yet) It does time out (but if you let it sit, suddenly it pops up, it seems to be at some sort of dynamic IP address that takes a bit to pop up. hope this hellps. bb On Fri, Dec 6, 2019 at 10:07 PM Jay Jaeger via cctalk wrote: > > On 12/5/2019 10:57 AM, John Foust via cctalk wrote: > > > > Back in 2000, Jay Jaeger generously helped me read some old backup tapes > > from a RSTS V7.0-07 system. > > > > I'm not sure why I hadn't tried before, but I recently thought I could > > try to run those circa-1982 BASIC-PLUS and FORTRAN programs under emulation. > > And maybe even in a browser.

If you try to solder to the case, the electrolyte will evaporate causing excess pressure in the case. This will burst the seal. For a lithium coin cell this can mean a fire. As was mentioned, the solder tabs are usually spot welded to the case. The heat is momentary and little pressure is created in the cell. I've dismantled the machine enough now to get the mainboard out. Right behind the cell on the opposite side of the PCB are expansion memory boards. Between those and the PCB is a black square of insulating plastic that is tackily glued to the PCB. That lifts up easily enough. There are plenty of components on this side of the PCB too. It looks like one tab is right by the label "R337" and the other is between the "R346" and "R351" labels. Just in case anyone else ever follows this path :-) I'm going to set it to one side for now and get to the same stage with the Acorn A3000 (which looks OK but the battery really has to come out now ... it will eventually fail I suppose). I might as well tackle both at the same time ... Maybe I'll take photos as I put it back together, sort of "Haynes manual in reverse". Antonio -- Antonio Carlini anto...@acarlini.com

Yes, I've done that, and it runs fine there. >There are at least three files involved, I spect: pdp11.html, pdp11.js >and bootcode.js, and probably vt11,js, pdp-11-45.svg and pdp11-70.svg as >well. Yes, I've been wishing it was better documented. But all the source is there. - John
