Re: Upgrading Kurzweil 1000 PX: Should I touch the soldering iron to the two solder pads of JP03??
If I were doing this, I think the first thing I'd tell the repair shop was the url to K1000.net, so they could see what was in play.

Re: Upgrading Kurzweil 1000 PX: Should I touch the soldering iron to the two solder pads of JP03??
Definitely not.? Proper soldering
involves heating the points / pads / leads to be soldered to about
the melting point of the solder, then applying solder to the
joint.? This should be done fairly quickly.? Correct size / power
iron , experience, etc...? Like welding, it is easiest to learn of
fairly big stuff first, then work your way dow to smaller and
smaller, preferably on non valuable practice items.? Get a few
electronic devices at a tag sale or thrift store.

The soldering iron would melt the two solder pads (at least
somewhat) which seems like a bad thing,? but would simply dripping
solder wire down on to the two solder pads even allow proper
binding/adhesion between the solder wire and solder pads?? :/
Does anyone have experience with this?

Wherever you live there should be a computer/electronics repair center near you. Patrick

I Suggest you have someone with soldering PCB skills do it for you, ?you need a good clean solid joint. ?

Re: Upgrading Kurzweil1000 PX to Pro-1: How to cut the etch of JP04???
It doesn't matter which part of the trace is cut.? The objective is
to prevent current from flowing between the square solder pad and
the round one, and as long as the trace is cut somewhere between
them, you'll accomplish this.

Hi. Which part of the trace to cut? The green line in the center
or the coppery color ones, or both?? (the arrows point to the
lines I'm referring too)

Re: Upgrading Kurzweil1000 PX to Pro-1: How to cut the etch of JP04???
If you've never seen a multilayer PC board layer before they're bound together, it's hard to fully understand how delicate this can be. (I have, I did a summer working in my uncle's printed circuit board shop) The layers are like the transparencies teachers used in school on an overhead projector. Yes, that thin. A light hand is the best idea when working with things like breaking traces. Think of it as being in the same general philosophy of the woodworking advice, measure twice, cut once.

It says not to cut too deeply because it's very likely a multi-layer board. I don't know how many layers, but surely more than one. IF you cut deep enough to break an inner layer, you got some real troubles that might not be easily repaired by even a talented tech. Also, and more likely, the idea is to *scrape*. A cut doesn't really give you the gap that you're after. You need a positive, uncompromising, interrupt to current flow and that means visible air (a very good example was provided).

Maybe 1,000 pulses are to be stopped with that jumper disconnect, but because it flexed or something, maybe 12 get through. Now what? Well, the results are entirely unpredictable. So make sure it's a good scrape like the pic Juan provided. If it still won't wake up after that, then it's possible there's another problem area.

My results, using cutting knife, and soft cut trace.? I prefer to pass the knife 20 times very softly than a single cut; this means to me: less damage to board.

I haven't done it, but I've had it done a lot. Which guide are you using? Does k1000.net cover this?

I think I destroyed the circuit board by cutting too deeply the etch of JP04. In the guide it says not to cut JP04 too deeply- but it doesn't say why: There is no text on the screen of the Kurzweil 1000 anymore, and I think it can no longer access the OS EPROMS, also I cut deep enough to expose some coppery bits. Please be careful cutting and don't make the same mistake I did. :( How would I avoid doing this again? Does anyone have experience upgrading a 1000 PX?

Thank you Nicole and others.
I'll make enquiries.

I have joined this list after this morning upgraded my Kurzweil 1000. It has been several years since I used this application. Between my last use of K1000 and now, I have installed an Index Everest embosser. In setting up the properties for K1000 to properly print to this, I notice three choices for correctly forcing new pages. Form feed, vertical tab and skip lines. K1000's default are 40 characters per line, 25 lines per page. These can be adjusted. There are no settings for binding space and number of blank lines at the top of each page and page number position so I presume the embosser just looks after those. The setup is Windows 11, and I use the supplied Index driver which is networked. Experimenting of course, but if others have found the configuration which works - I'd be pleased to learn about it. Thanks. Vaughan. Vaughan Dodd Vdodd001@... +6421 784 856
