+Larry Posted March 26, 2015 Share Posted March 26, 2015 I'm choosing a host for my VBXE (Candle, V2), and I'm leaning toward a 64K, 600XL. Has anyone done this or know a reason why it would be more difficult than an 800XL or XE? -Larry Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 26, 2015 Share Posted March 26, 2015 I think it's been done. I suspect the RF modulator might need to be taken out though... there's not nearly as much space available above Antic, remembering the adaptor board plugs in then VBXE board into that. Another issue might be clearance of the keyboard. You'd either need to ask candle, FJC or trawl through the VBXE install threads. It's been something like 5 years since I installed mine (800XL) and probably 2 years since I've even looked inside the machine so it's becoming an old memory.

flashjazzcat Posted March 26, 2015 Share Posted March 26, 2015 Yeah it'll fit, but you'll need to use the XL adapter which throws the VBXE out from behind ANTIC and possibly lower a few components on the motherboard. I'll grab some photos later on. Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted March 26, 2015 Share Posted March 26, 2015 Here are a couple of photos of my 600XL installation: As Rybags said, the RF modulator definitely needs to come out, and I un-socketed a few ICs behind ANTIC to ensure the VBXE lay reasonably flat: 2 Quote Link to comment Share on other sites More sharing options...
+Larry Posted March 26, 2015 Author Share Posted March 26, 2015 Thanks, Jon! I appreciate the photos. Looks nice in yours. This somewhat hinges on Lotharek selling me an XL adapter. That adapter looks very handy -- I've seen other things that need the set-back. -Larry Quote Link to comment Share on other sites More sharing options...
Mathy Posted March 26, 2015 Share Posted March 26, 2015 Hello guys Does anybody have a picture (or two) that shows the difference between the (VBXE with the) XL adaptor and the XE adaptor? Sincerely Mathy Quote Link to comment Share on other sites More sharing options...
+Larry Posted March 26, 2015 Author Share Posted March 26, 2015 If you look at the two photos at Lotharek's site, then you can see the difference. Not well, but you can tell. The XL has a of more setback than the XE. Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 27, 2015 Share Posted March 27, 2015 XE version of VBXE is different, has the long pin header pointing downwards where the XL one comes off the end of the board, so Antic adaptor obviously different to match that. I should also have added. You need it to be a 64K or more base machine before you start. If 64K then it's best to run VBXE in "R" Rambo compatible mode otherwise run in native "A" mode firmware.

For now, my 80 column ANSI terminal emulator even runs in 16K. EDIT: well, I thought it did, but now that I think about it, I probably creep just over the 16K line since I am (inefficiently) placing things after the VBXE memory window, thus wasting a whole 4K, plus whatever free space there was before the 4K boundary that the memory window lies on... (guess I'll fix that, I'd like to be able to boast that it runs in 16K) EDIT 2: fixed Edited March 27, 2015 by Joey Z 1 Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 27, 2015 Share Posted March 27, 2015 Technically it's fine to run VBXE on a 16K system. But practically, you'd probably find that no software designed for it would work. The trouble and expense of a VBXE upgrade is ~ 1-2 hours labour and $150 or whatever it costs these days. The trouble and expense to upgrade a 600XL to 64K is ~ 1/2 hour labour and a few bucks at most for 2 Ram chips. Quote Link to comment Share on other sites More sharing options...
+Larry Posted March 27, 2015 Author Share Posted March 27, 2015 Well, bad luck for me -- Lotharek can't supply the XL adapter as a separate purchase. But looking at my XE VBXE, is there any reason that I can't connect the VBXE to the adapter via this? http://www.amazon.com/Phantom-dupont-cable-200mm-female/dp/B00A6SOGC4/ref=pd_sim_e_3?ie=UTF8&refRID=0500Y42AZXZ0DZN3CM7N Alternatively, I could desolder the female connector on the VBXE and put in regular header pins and then use a ribbon cable and female connectors at both ends, but I'd like to avoid desoldering on the VBXE. -Larry Quote Link to comment Share on other sites More sharing options...
Rybags Posted March 27, 2015 Share Posted March 27, 2015 I guess a ribbon cable could work, we use them for our Ultimate 1 Megs. It comes down to placement in the 600XL though, space can be a real issue. And you'd probably want to have consideration for future upgrades like U1Meg.

I imagine for such 'low speed' it would probably be fine though. Quote Link to comment Share on other sites More sharing options...

Normally I would, but for this one, I plan on having an accelerator in there. The accelerator has on-board Rambo, and it also takes care of the the base 64K. CPU, MMU, ram, and a couple of support chips get pulled. The accelerator drops in. The VBXE does require some work, but when this is finished, it should make a very nice machine. At least that's the plan. -Larry Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted March 27, 2015 Share Posted March 27, 2015 (edited) I think I can provide a spare XL adapter, but some desoldering work on the VBXE will be unavoidable (which I could also undertake). Did Lotharek explain what's preventing him from selling you an adapter? Edited March 27, 2015 by flashjazzcat Quote Link to comment Share on other sites More sharing options...
+Larry Posted March 27, 2015 Author Share Posted March 27, 2015 Hi Jon- Thanks, but let me try my cable hookup before you do anything. I've already ordered the cable from Amazon. Lotharek says he doesn't have spares -- just enough for his VBXE's. I've got a Hakko desoldering gun -- if push comes to shove. :-) I see what you mean by looking again more closely at the pic you posted. I think that XL adapter would be handy for quite a few things -- just leave the 40-pin connector off the adapter board so that the user could configure to his/her needs. In fact just selling the pcb would give a lot of flexibility -Larry Quote Link to comment Share on other sites More sharing options...
BillC Posted March 28, 2015 Share Posted March 28, 2015 The VBXE/adapter connection is a 40 pin header, perhaps a short IDE extension cable. This would be much easier(and less risk of damage) than desoldering the female header from the VBXE. They are available in various lengths. http://www.ebay.com/sch/i.html?_from=R40&_trksid=p2047675.m570.l1313.TR0.TRC0.H0.X40-Pin+Male+to+Female+IDE+Extension+Cable.TRS0&_nkw=40-Pin+Male+to+Female+IDE+Extension+Cable&_sacat=0 1 Quote Link to comment Share on other sites More sharing options...

Thanks, for some reason, I could only think of female-female connectors. If that cable that I ordered doesn't work well, I'll get one of the IDE extenders. -Larry Quote Link to comment Share on other sites More sharing options...
