+orpheuswaking Posted July 25, 2017 Share Posted July 25, 2017 Still working out some bugs on a couple boards. On the plus side it's allowing Michael to continue to refine the board. Quote Link to comment Share on other sites More sharing options...
+mytek Posted July 25, 2017 Author Share Posted July 25, 2017 Ditto on what orpheus said. As it turned out the whole issue of being able to have internal direct connectivity for SC1224 ST monitors via VBXE and Sophia upgrades through the on board DIN-13 jack, was a big bust and needed an overhaul. In order to arrive at this conclusion, I first needed to get my hands on a monitor to test with, which I recently lucked out and got a good working one for a steal from a fairly local source (I hate the idea of shipping CRT's across the country). And then my luck was extended when Bob Woolley and I were able to find two more in his stash (one JVC and one Goldstar). I'll be testing with his Goldstar one down the road. Anyway suffice it to say I now have a working solution, and a once again revised PCB layout based on discoveries made in the last several days. - Michael 2 Quote Link to comment Share on other sites More sharing options...
+Stephen Posted July 25, 2017 Share Posted July 25, 2017 Well, I seem to be the last one with a non-working (PAL) setup. I'll post my latest detailed findings. The initial problem was corrupted PMG when running in PAL mode.Upon advice from Mike, I switched U11 from a 74HCT08 to a 74LS08 and reomved the jumper between pins 5&6. This made the system completely unstable. It would crash before booting most times, and from SDX, just doing a DIR CAR: would guarantee a lockup. Also, the PMG corruption was still there. I tried running NTSC clock & crystal with the PAL chips installed. I still got PMG corruption and crashes. Swapped CPU (original was UMC UM6502I out of an 800XE) for a 1200XL CPU. System seems stable now (before, DIR CAR: would immediately crash) but PMG issue is still there. So I started swapping ANITC and GTIA chips (both NTSC and PAL) and discovered: Everything works UNTIL a PAL ANTIC is installed. AMI 9119MFU system is completely unstable with 74LS08 AMI 8730MDX system is more stable but still has borked PMG When in SDX, doing a DIR CAR: will crash it in 2 lines.PAL clock with NTSC ANTIC - everything works finePAL clock with NTSC ANTIC & GTIA - everything works fine I'm at a loss for what to check next, but hopefully these symptoms can offer a clue as to what the problem is.

+Firedawg Posted July 25, 2017 Share Posted July 25, 2017 Thanks to Michael and his test crew!!! I will not lie as my anticipation level is high. I have been involved in development projects in the grassroots and trust me these guys are taking on the bugs and hitches that we do not want to deal with when the board is released into the wild by Michael. Take your time fellas and do what needs to be done. Thanks again!!! Mike 5 Quote Link to comment Share on other sites More sharing options...
+mytek Posted July 25, 2017 Author Share Posted July 25, 2017 Did anyone ever see the remake of the 'The Fly' movie that came out many years ago with Jeff Goldblum? To put it into a nutshell a terrible accident occurs when he tries to teleport himself unknowing that a fly slipped into the chamber with him. Bad news was that it created a version of himself mixed with fly DNA, never a good thing. Anyway I think Stephen's XEL board might have suffered the same fate, only heaven forbid a C64 sneaked in when it got teleported {media]https://www.youtube.com/watch?v=Q-kf8NYhoCQ[/media] - Michael 4 Quote Link to comment Share on other sites More sharing options...
toddtmw Posted July 27, 2017 Share Posted July 27, 2017 I know I asked and the answer was "no", but I would love to see an option where you could hook a board to a standard 3.5" IBM floppy and then connect to to SIO. (Kind of like what you can do with an XF-551, but without the XF-551.) Thoughts? Quote Link to comment Share on other sites More sharing options...

toddtmw Posted July 27, 2017 Share Posted July 27, 2017 Oops. I posted in the wrong thread. I asked over in that thread and was told that it wouldn't work that way. (These threads have similar names...) Quote Link to comment Share on other sites More sharing options...
Kyle22 Posted July 27, 2017 Share Posted July 27, 2017 Todd, since you posted here in this thread, I kind of assumed you wanted an INTERNAL board for an INTERNAL drive. That's what this project is, an Atari in a PC case. A really small and nice one at that. If you want an external, normal, proper XF-551, then Best Electronics has them in stock, and you can easily find the Bob Wooley XF 3.5 Mod. by searching. 1 Quote Link to comment Share on other sites More sharing options...

marty Posted July 27, 2017 Share Posted July 27, 2017 Wow! Double wow! I hope you aren't tired of hearing this but will someone here eventually produce a finished a turnkey version of this board with case and storage? 2 Quote Link to comment Share on other sites More sharing options...
+mytek Posted July 27, 2017 Author Share Posted July 27, 2017 You know, feature creep can go on literally forever. Yes I agree. So that is why only those things that are required to get all of the originally planned aspects fully working are being implemented at this point. Some things were enhanced from V1.0 to V1.1, and some additional break-out headers were implemented, but nothing radically new has been added. Whatever is going on with Stephen's board concerning PAL, will not hold up having the next small run of test boards made, since thus far his appears to be an anomaly that is likely associated with something external to the motherboard design. I say this because for the most part all circuit aspects concerning timing are essentially replicated from an 800XL, and we also have two boards that do work correctly in PAL mode. My only limitation is money, but even that won't hold up the next run for long. Wow! Double wow! I hope you aren't tired of hearing this but will someone here eventually produce a finished a turnkey version of this board with case and storage? That is a very good question, and not one that I can answer with any certainty. Anyone is free to do so once the designs have been released, and no one needs to seek my approval in order to do so. - Michael 3 Quote Link to comment Share on other sites More sharing options...
Theoryman Posted July 30, 2017 Share Posted July 30, 2017 Got my U1MB, Rapidus and my VBXE today... Got my ITX case. Got a 5VDC 5A brick to go with the case... Got my Atari chipset chips...

Do you need a beta builder for the new PCB revision? -- 5 amps is pretty hefty. Just so some someone doesn't get the wrong impression, a 2 amp power supply is more than sufficient, but more amps certainly doesn't hurt. Thanks for the offer to beta, but that was really only required for the first rev boards, which had a lot of uncertainties due to the newness factor, and not knowing what was critical, and what was not. - Michael Quote Link to comment Share on other sites More sharing options...

+mytek Posted July 31, 2017 Author Share Posted July 31, 2017 Status Update Stephen's going to send me his board to scope out, so I will at least wait on ordering the verification board set for V1.1 until I have had a chance to see what is causing his PAL issues, as well as some of the other instabilities he reported when changing the 74HCT08 to other faster versions. Be good to rule out any potential design problems that might be attributable for these quirks. - Michael 8 Quote Link to comment Share on other sites More sharing options...

+mytek Posted August 1, 2017 Author Share Posted August 1, 2017 Now for a tease... I got some panels made at Front Panel Express and I've got to say it really starts to give a more complete image to what I had in my mind. Still need to install the new 3D printed Cart Tunnel (being fabricated), and also the status LED pcb (also being fabricated), but this thing is really starting to take shape. - Michael 18 Quote Link to comment Share on other sites More sharing options...

+H454 Posted August 2, 2017 Share Posted August 2, 2017 That looks amazing! Is their and Idea on pricing? even just a ball park? Also, are you going to try using something that isn't blue LEDs or worse RGB? Red LED always look right, I can't be the only one tired of super bright blue on everything. Super excited for a release, most cool projects die early on, enter development hell or are one offs. Thanks for seeing this through! 2 Quote Link to comment Share on other sites More sharing options...

Also, are you going to try using something that isn't blue LEDs or worse RGB? Red LED always look right, I can't be the only one tired of super bright blue on everything. Super excited for a release, most cool projects die early on, enter development hell or are one offs. Thanks for seeing this through! The power indicator has a blue LED (comes that way), but all the other LEDs will be green, with one red one for the SIO2PC TX status. EDIT: maybe I'll make the CF Card activity also red. If I were to ballpark the case with the custom panels I would say roughly around $200 including shipping (this hobby isn't cheap ). Of course this is my first take on enclosing the 1088XEL motherboard, and I'm sure there are cheaper (as well as more expensive) ways to go. Anything I do will be a part of the final release, so that means the panel files are included if anyone wishes to copy what I've done, or wants a good starting point for their own customization's. I'm really looking forward to seeing what other people's take on an enclosure will be . - Michael Edited August 2, 2017 by mytekcontrols 3 Quote Link to comment Share on other sites More sharing options...
+Stephen Posted August 2, 2017 Share Posted August 2, 2017 That is just beautiful! I'm really glad I ordered that Realan case now. I'll definitely be ordering those top and back panels! What are you using for the Atari logo on the front of the case? 1 Quote Link to comment Share on other sites More sharing options...
