  1. Will you be making the 3D models for the plungers available? If they are on your github, I guess I don't know which files. I was thinking it would be an .stl file. I would be interested in a plate and PCB as well. Nevermind on the file, I'm very new to 3D stuff, so didn't realize the .scad file was what I needed..
  2. @bfollowell Look up drag soldering videos on youtube, the key here is high quality flux, don't skimp. Alignment is also key, make sure the contacts are perfectly aligned, and it will go smoothly. I usually will put solder on only one contact, then move the piece to be soldered onto that pad, while holding the iron on that pad. Reposition if necessary, until you get the alignment nailed, then you drag solder from the opposite side. For hand soldering, this is much easier than using paste and a heat gun, which can definitely warp a flex circuit. In fact unless you have a stencil and a reflow oven, for the most part drag soldering is the most effective and easiest in my experience.
  3. Thanks for all the suggestions, I'll take a closer look by this weekend. @mattsoft Thanks, I don't have a problem with doing that, is this a typical symptom of caps?
  4. Lines are moving, and jittering, though they seem to slow down as it warms up.
  5. Was wondering if anyone had any ideas on what's causing this horizontal line distortion on this monitor. Was working, but now I'm getting this. I do have a service manual, but definitely not familiar with CRT troubleshooting.
  6. The TL866II+ cannot program Eproms that require +21V for the programming, it only goes to +18V, that might be the problem. However on another note, they work great with EEPROMS like the Winbond W27C512, which are pretty easy to get, and not that expensive. I found an Aliexpress shop that sells genuine versions, that are used, but in great condition for basically $1 a piece.
  7. It could also be that there are existing issues with VBXE, that have been brought up ad nauseum, for literally years and haven't been addressed, which doesn't help in people wanting to use it. Ignoring your userbase seems counterproductive.
  8. The board is a 130XE remake, that is mostly just a duplication, but also UAV has been added on board, as well as a 512k Ram upgrade, also a TK-II interface is available (not mandatory), which allows you to hook up a PS/2 Keyboard. Technically it's remake of the 65XE, because it only has 64k Dram, if you don't use the 512k upgrade. It does need a case with an ECI port. Santosp only made a few runs of the board, supposedly some are also available through ABBUC, but I hadn't heard any info other than that.
  9. FYI, just in case anyone didn't know. You can use the AT28C64 to replace the 27Cx, and it is much easier to get, plus as an EEPROM it is easily re-flashed, no UV needed, you can use this as replacement for Basic roms. Also the GAL22V10, can be replaced with ATF22V10C also an EEPROM, again easier to source, and flash (at least with a TL866II+ burner). This is what I am using in my board.
  10. A few questions for you adam242, you say you are using the standard video output, have you tried the UAV output, since you have that populated? Are you getting any sound, you know the standard "pfffftttt" when it boots? If you are getting sound, at least that narrows down to video issues most likely. I would suggest highly that you get the U34 populated with the sram13.jed flashed to it. There are a lot of signals being remapped through that chip. My note was definitely with the 512k SRAM, and U34 22V10 installed. The only difference with my setup was no battery backup. This remake board was designed specifically for the 512k integrated, just from probing myself, I know that the MMU Pin 16 that is normally connected to Freddie Pin 4, is not physically there, specifically to use this memory upgrade, normally you would have to lift that pin and solder to it, connect it to the 22V10, and some other stuff. It probably won't work without it. Not sure why you are leaving the memory upgrade out, it's not like the chips are expensive. It's less than $10 for both chips (512k SRAM, and ATF22V10C) at Digikey. I can't see what Santos said with the two bridges so not sure about that.
  11. I guess I was just looking for background information, faqs, that sort of thing. Stuff you might expect to find under docs.
  12. I've tried to go to the Spectranet site (http://spectrum.alioth.net/doc/index.php) for a few months now, it seems that it is non-functional, and based on what I've searched out, it seems that it's probably been abandoned, or not updated in quite a while. Thanks
  13. Ah nothing special, I just misread in the VBXE install instructions the D6XX connection, thought it was only needed if using U1MB. It doesn't work to good without it. I couldn't figure out why it was working in my 1088XEL, but not on this board. RTFM closely..
  14. Nevermind, I figured it out. I can be stupid sometimes..
  15. Anyone running VBXE on these yet? I'm having some issues getting it running.
  16. I was confused as well. I can verify that you cannot use the original Atari factory basic rom, the mod has nothing to do with it. If you want to use the factory rom, you would have to create an adapter to switch the pinout. In order to use a 27Cx, you need to do the mod, it won't work otherwise. One other note, I didn't want the battery backup, so I didn't order/install parts for it. You need to jump pins 5-6 on the U12 footprint, otherwise no worky..
  17. Would it be possible to get the VBSOX3 plugin with the NTSC palette?
  18. Santos, I actually thought the upgrade of the video connector to 8 pin DIN was very clever. I think that it might have worked with both at the same time. I think you can use composite video as substitute for CSYNC (I could be wrong about that), so you would only need the RGB connections, as Sync (Composite), Audio, and Gnd are already available, without having to disconnect UAV, not sure why you have +5V there, I don't see that connection on VBXE output. After I get everything working, I may actually try this to see if it works, using composite for sync. On another note, I noticed a 75ohm resistor silkscreen on the board (not part of UAV portion), but it wasn't listed in the BOM, was it just missed, or is this actually supposed to be a different value? Looking at the two revs, it seems this is only on the Rev2 board. After checking the Mouser project, it does seem that the 75ohm resistor is there however.
  19. I can't remember, but if there is an encrypt selection, that will also cause it to fail on verify. The other thing is if you are trying to do vector tests on the TL866II+, there was a slight issue on the configuration of the test that caused it to also fail. You can see the issue, and solution here: I'm assuming that XRAM should be able to test the 576k for functionality.
  20. So SJ1 isn't a component, but a jumper? Does anything need to be removed component wise from the motherboard (like the standard 130XE), or is it taken into account already? VBXE install instructions aren't very clear on which components either, it just has a red square that says remove all components in the picture, but that includes Freddie, which I don't think is the case. If I'm understanding correctly, in order to use UAV, first have to remove jumpers from 4-5, and 7-8 used for VBXE, then place jumpers for UAV. Both VBXE and UAV cannot be connected at the same time with this configuration, of course adding a separate connector for one or the other would allow that I believe. But no tying 1-4-5 and 3-7-8 together. To do this without opening the case, could wire in a DPDT switch for this purpose. The question was for this board specifically, using the built-in connections, not in a general case, I was aware that they can be used together, as I had them working on 1088XEL.
  21. Completely missed the note in the original BOM about reusing the Ferrites, duh.. I do have one other question, along with those left above. What is the SJ1 surface mount component on the backside? Seems that it goes to the 5V to Pin4 on the UAV/VBXE jumpers. Seems kind of critical since it's an open otherwise. I don't see it in the BOM, or in the Mouser cart.
  22. Any idea when we might be seeing this core palette change, for those of us that aren't using this with U1MB?
  23. Got my board the other day, looks good. Have a few questions.. Can UAV and VBXE be run at the same time, or is it one or the other? Are there VBXE install instructions for this? The normal 130XE installation is calling out a bunch of parts that need removing, not sure if parts needed to be removed, and if so, which ones. I'm assuming the Video Setup 10pos header is for the VBXE connections, not sure which ones to connect to which. I could back trace, and make some educated guesses, but if you have a list already, that would be better.. Can Ferrite beads be reused from original 130XE MB?
  24. Thanks, I did look in the Bom that was posted here, but there weren't specific numbers, and I didn't see a link for a basket/shopping cart.
  25. Santos, regarding the SMD ICs for the UAV. Are all of these SOIC format? There are several different SMD footprints for these, including different SOIC as well, the BOM only specifies model, not specific footprint.
