kerobaros Posted December 29, 2019 Share Posted December 29, 2019 Hi all! Recently received a 600XL from a friend, and it seems to boot just fine. Now I need to upgrade the RAM on it, which seems easy enough, along with put a monitor jack into it. Are there any kits available for either of these mods, or do I have to track down all the individual parts myself? Once I get all that done, I'll have to decide between getting an Sdrive or the Ultimate/SIDE combo... thoughts? 1 Quote Link to comment Share on other sites More sharing options...
Paul Westphal Posted December 29, 2019 Share Posted December 29, 2019 64k mod. Ram chips are 4464’s. Best electronics might still have a monitor port kit, and consider the UAV board from The Brewing Academy 1 Quote Link to comment Share on other sites More sharing options...
JR> Posted December 29, 2019 Share Posted December 29, 2019 2nd the UAV. Very simple way to get good video out f the 600xl. 1 Quote Link to comment Share on other sites More sharing options...
xrbrevin Posted December 29, 2019 Share Posted December 29, 2019 cartridge solutions load games very quickly, SIO devices are a little slower but not much and both are v.user-friendly to use UAV gives great image quality and fitment is straightforward/uncomplicated Quote Link to comment Share on other sites More sharing options...
Paul Westphal Posted December 29, 2019 Share Posted December 29, 2019 Xrbrevin, if you could share a high Rez pic of your 600xl UAV install I would greatly appreciate it. Quote Link to comment Share on other sites More sharing options...
Paul Westphal Posted December 29, 2019 Share Posted December 29, 2019 FYI - It’s hard to tell in the pic, but one foot on that resistor next to the 4464 ram chip has been cut, lifted and had the wire soldered to it. 1 Quote Link to comment Share on other sites More sharing options...
kerobaros Posted December 30, 2019 Author Share Posted December 30, 2019 Alright, I ordered some 4464 compatible ICs from eBay, we'll see how long they take to arrive. Looking at the Brewing Academy's storefront, it seems that I want the plug-in model of the UAV board, right? Is there a good place to get the correct DIN socket for the monitor jack?

mimo Posted December 30, 2019 Share Posted December 30, 2019 @tf_hh makes a ram upgrade, 512k iirc. Also, check out how he uses a cable for av out on his SCCC board for the 400, it may be easier to do something similar for your UAV upgrade on the 600xl?

xrbrevin Posted January 2, 2020 Share Posted January 2, 2020 yes, inconsistent part numbering.. pincount confirmed good for this venture tho ? Quote Link to comment Share on other sites More sharing options...

Not really, the part numbers differed between manufacturers. I know them as 4464, probably because of TI, many others used 41464. Fujitsu: MB81464 Motorola: MCM41464 NEC: D41464 Samsung: KM41464A/KM41C464P Texas Instruments: TMS4464 Edited January 3, 2020 by BillC Quote Link to comment Share on other sites More sharing options...
kerobaros Posted January 3, 2020 Author Share Posted January 3, 2020 If the Postal Service cooperates, I should have two deliveries today: one package with my RAM ICs, and one package from the Brewing Academy with a new power adapter, a monitor jack, and a UAV board. I desoldered my channel 2/3 switch and cleared the solder out of the monitor jack mounting holes before work last night in preparation for a busy evening of soldering. Quite excited! I'll keep you all updated how things go. Also, I managed to rig together an SIO2PC cable the other day from parts I had around the house already, and tested it out by loading the cassette version of Space Invaders. Any suggestions for what I should use to test my system after I get things out back together? Quote Link to comment Share on other sites More sharing options...
xrbrevin Posted January 3, 2020 Share Posted January 3, 2020 sounds like you have a good session lined up hehe ? test with your favourite games but also try 64k games too. it should behave just like an 800XL after the RAM mod. the inbuilt RAM self-test should be booted with option held in order not to load basic. UAV is super-sharp compared to standard so any software will give pleasing results Quote Link to comment Share on other sites More sharing options...
Sugarland Posted January 3, 2020 Share Posted January 3, 2020 I also recommend UAV connected to a cable running to a female 5 pin DIN coming out of the back of the computer like the SCCC uses. This way no case modding/drilling is needed. Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted January 4, 2020 Share Posted January 4, 2020 The 600XL has great s-video once the blurring cap is removed. If you can be bothered to find/do the 600XL Supervideo mod, it's even better. 1 Quote Link to comment Share on other sites More sharing options...

SS Posted January 7, 2020 Share Posted January 7, 2020 I am late to the party on this one but I have a 600XL with an ANTONIA board and a SOPHIA board installed in it. This gives the 600XL a huge RAM upgrade, seven selectable OS and BASIC slots, and a digital output. It is pretty much a perfect machine now.

Please elaborate I forget the component number at this point, but if you search for tf_hh's comments on 600XL video tuning, all will become clear (literally!).

+tf_hh Posted January 7, 2020 Share Posted January 7, 2020 On 1/4/2020 at 1:25 AM, kerobaros said: Blurring cap? Please elaborate. It´s a 180pF ceramic cap, mostly in disc shape, with component name C109. Remove it and the picture will be MUCH clearer. 2 1 Quote Link to comment Share on other sites More sharing options...
xrbrevin Posted January 7, 2020 Share Posted January 7, 2020 is it still beneficial to remove the blurring cap even if you already have UAV installed? Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted January 7, 2020 Share Posted January 7, 2020 I did this plus a full SuperVideo mod on one 600XL and aside from some feint clocking bars (which perhaps the blurring cap was supposed to obscure) which may be alleviated by better cable shielding, s-video is really nice... one level below UAV quality, IMHO. 1 Quote Link to comment Share on other sites More sharing options...
