NISMOPC Posted December 30, 2020 Share Posted December 30, 2020 So, I took last two weeks off from work and since I finally had some free time, decided to work on what will become my daily set-up. 130XE with following upgrades all done by me: - 512k SRAM from tf_hh - Stereo dual pokey from tf_hh with push button mono/stereo - 4in1 OS switch from Dropcheck with 2 push buttons to select each ROM. I burned XL Boss OS, 1200XL v11 OS, XE/XL v2 and XE/XL v4 just to test out. Need to order some Eproms as the ones I have are not erasable. Currently using Best Electronics A/V monitor cable to flatscreen TV. Sporting the FUJINET SIO and my newest addition is the XF551 I rcvd today. Future plans are XF551 firmware update and some type of video upgrade, but super happy with results. Yes I kept the shield and yes it took a long time to dremel out all the openings, but d@mn it looks cool. 6 Quote Link to comment Share on other sites More sharing options...
NISMOPC Posted December 30, 2020 Author Share Posted December 30, 2020 And a video of Yoomp! And me switching from stereo to mono and back. VID_20201230_154553755.mp4 2 Quote Link to comment Share on other sites More sharing options...
Dmitry Posted December 30, 2020 Share Posted December 30, 2020 So nice. I like the matching xegs joystick and the modern white desk too - it really completes the cleanness of the look. Quote Link to comment Share on other sites More sharing options...

I've got to say, I am really impressed with the job that you did on cutting the shielding. It looks fantastic! I took the easy way out on all of my mods and just lost the top shield altogether. Very nice work! 1 Quote Link to comment Share on other sites More sharing options...
+Larry Posted December 31, 2020 Share Posted December 31, 2020 Very nice setup! S-video? And push buttons for the OS switches. That's something I haven't seen before. Quote Link to comment Share on other sites More sharing options...

That's something I haven't seen before. Thanks! Currently, the A/V cable is composite. Need to buy or make a S-video out. The plug on left is the 3.5mm stereo jack and mono/stereo switching (blue button) Edited December 31, 2020 by NISMOPC 1 Quote Link to comment Share on other sites More sharing options...
NISMOPC Posted December 31, 2020 Author Share Posted December 31, 2020 Having some odd SIO issues w/FujiNet and XF551. Going to remove the caps on the SIO pins. Seems to be hindering high speeds at certain times. Quote Link to comment Share on other sites More sharing options...
NISMOPC Posted December 31, 2020 Author Share Posted December 31, 2020 Definitely want to thank @Dropcheck and @tf_hh for their awesome products and @flashjazzcat for his recent XEGS upgrade video which inspired me to do this. 1 Quote Link to comment Share on other sites More sharing options...

Going to do the cap removal as a first pass since they are known to cause issues anyhow. No need for them... Quote Link to comment Share on other sites More sharing options...

Your post inspired me to put finally the Sophia2 sitting on my desk into my 800XE, and am looking forward to get my XEGS back from Jon ?

Here is a previous post of mine, where I show the locations of the specific caps to remove: https://atariage.com/forums/topic/290397-atari-sio-transmission-oscillogram/?do=findComment&comment=4352330 On all XE's remove C77/C78 On earlier XE's deslolder at minimum the PCB end of the ball of bodge caps that go to the SIO connector pins On later XE's where the SIO caps were integrated into the motherboard, remove C303 and C304. 1 Quote Link to comment Share on other sites More sharing options...

As can be seen, mine is the wonderful "blob" version and I will be removing all of them. I will read up on the C77/C78 as well before removing those two. This is the first time I read about those two. Quote Link to comment Share on other sites More sharing options...

This is the first time I read about those two. Oh, and lastly adding a pullup resistor to C78's location gives the cleanest transmit signal from the Atari, and allowed the fastest divisors 0,1,2 for me to a SIO2PC-USB even passing through a 1050 in my case. https://atariage.com/forums/topic/290397-atari-sio-transmission-oscillogram/?do=findComment&comment=4353844 Note: In that post I described it going to the right side of C79 in that linked post, but I meant C78 as pictured...
