Ricky Spanish Posted September 11, 2022 Share Posted September 11, 2022 So after some serious consideration, I've decided to get the U1MB for my ATARI 1200XL All I need is just the unit & nothing else, correct ? Is there a instructional PDF or similar for the U1MB that explains the install & functions of it ? Can't seem to find one. Thanks. 1 Quote Link to comment Share on other sites More sharing options...

+x=usr(1536) Posted September 11, 2022 Share Posted September 11, 2022 No worries Be interested to see how you get on with it; I'm giving it consideration as well for one of my 1200XLs. Quote Link to comment Share on other sites More sharing options...

Totally recommended, I love my U1MB/SIDE3 combo - Even better with FJC's latest firmware. 4 Quote Link to comment Share on other sites More sharing options...

Beeblebrox Posted September 11, 2022 Share Posted September 11, 2022 (edited) @Ricky Spanish good luck. Remember you will likely need to add a 100pf ceramic capacitor to the back of the U1mb re the known instability issue when used with a 1200XL. I had to. Dead easy.

Another option is Dropcheck's 1200XL cartridge extender PCBs. These also come in handy for doing stuff on a 400 or 800 where you need to have the cartridge door propped open but want easy access to the cartridge slot(s). Been using them for a couple of years in order to avoid filing cartridges and they work great. Quote Link to comment Share on other sites More sharing options...

My absolute favourite would be a switchable dual version with vertical slots (so it would take up less space left of the 1200XL). 1 Quote Link to comment Share on other sites More sharing options...

Funnily enough, SIDE3 was actually my use case for originally ordering one. Check the link - she's now offering both the original PCB and one with a right-angle slot that lets the cartridge sit vertically 2 Quote Link to comment Share on other sites More sharing options...
Ricky Spanish Posted September 11, 2022 Author Share Posted September 11, 2022 Ok, so other than the capacitor.. I don't need anything else and I can run the U1MB as is correct ? Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted September 11, 2022 Share Posted September 11, 2022 (edited) Given the 1200XL needs to be converted from a dual OS rom chip setup to single OS system for it to accept the U1mb, you'll need the 28pin OS and 20pin sockets for the os conversion as per FJC video and then capacitor should you need it. (Most likely will). Also if your U1mb is the cheaper version with the old 2012 candle firmware you'll wanna flash FJC's latest 2021 u1mb firmware. So you'll need a storage medium to do that, (SIO2PC connection , Sdrive max, Sio2SD, Side 2 or 3 cart AVG cart, etc).

Havok69 Posted September 12, 2022 Share Posted September 12, 2022 Ouch! That's only about five times too much! Or, its triple what I paid for my 1200XL... There must be somebody in the tundra where you live that could do the upgrade. We don't have any Canadian FJC's here? Quote Link to comment Share on other sites More sharing options...
+slx Posted September 12, 2022 Share Posted September 12, 2022 Some 1200XLs have those sockets already. Mine had and all I needed for the U1MB were a few motherboard connections and jumper wires. Iirc there were holes in the mobo for all the required signals. Quote Link to comment Share on other sites More sharing options...
Beeblebrox Posted September 12, 2022 Share Posted September 12, 2022 (edited) @Ricky Spanish honestly it's s not that tricky and all detailed in FJC's video. Give it a watch and you'll see. We'll worth it as ever to get all the U1mb functionality. It's all reversable if you keep hold of the Os rom's and mmu, etc. @slx the 1200XL's 2 x 16k OS Rom chips are 24 pin whereas the U1MB's ribbon connector is 28pin (the same as the XL/XE OS S ROM chip). The 1200XL's pcb itself comes with 28pin holes so did your 1200XL have 28pin sockets in which your 2 x 24pin rom's were installed? Mine didn't have sockets but I am very used to socketing A8 pcb's these days. Edited September 12, 2022 by Beeblebrox 1 Quote Link to comment Share on other sites More sharing options...

I'm sure it isn't any I watched all of his 1200XL videos many times. I still need donate to @flashjazzcat channel because frankly all the information he gives is worth it's weight in gold. Think I'll make that a monthly thing. <- I encourage everyone to do the same that watches his vids.

I think it did but I’m not 100% sure. It’s been a few years and I’d need to open it up and have a look. Quote Link to comment Share on other sites More sharing options...
