HiroProX Posted March 17, 2011 Share Posted March 17, 2011 (edited) I would like the second two corvus interfaces off the assembly line, please! For the record, what exactly has to be "tuned" between PBI of different Atari's? He was referring to how some mods cannot co-exist, for example, Internal MyIDE and IntSDX.

fibrewire Posted March 17, 2011 Share Posted March 17, 2011 Oh. I saw in other posts something about a timing issue. That sometimes an ICD MIO will need to be tuned, so i thought there was some kind of timing issue between PBI and peripherals. Quote Link to comment Share on other sites More sharing options...
HiroProX Posted March 17, 2011 Share Posted March 17, 2011 (edited) The only issue I can see with devising a standardized "PBI 2.0" is getting all of the most prolific hardware designers to sit down and begin hashing it out. That alone gives me mental images of herding cats. But it might be a good use for an IRC chat. Anyone game?

For the record, what exactly has to be "tuned" between PBI of different Atari's? He was referring to how some mods cannot co-exist, for example, Internal MyIDE and IntSDX. I would think the reference was to the variance in Phi2 timing on different machines, compounded by the increased bus capacitance of additional internal mods.The exclusivity of Internal MyIDE and IntSDX is primarily a physical one, which is to say you can't simultaneously plug both upgrades into the same OS ROM socket. An internal MyIDE on the CPU socket and IntSDX on the OS ROM avoids that problem, but the bus capacitance issue may require additional "tuning". I personally run a 130XE with IntSDX, a custom CPU-mounted RTC board, Stereo Pokey, VBXE2, and a 1MB RAM upgrade. However, it required a timing mod before an extenal MyIDE cart would work. Whether this is solely down to the proliferation of internal mods, I am uncertain. Edited March 17, 2011 by flashjazzcat Quote Link to comment Share on other sites More sharing options...

Wouldn't it be best to just survey them and someone like MG or Curt make the call? Edited March 19, 2011 by Defender II Quote Link to comment Share on other sites More sharing options...

Well the first thing is to figure out what, if any additional signals are needed for new hardware ideas, etc. Quote Link to comment Share on other sites More sharing options...
Louis Posted April 12, 2011 Share Posted April 12, 2011 Is there a system to use multiple cartridges on the same system? Or is the 1090XL basically what it does? In that case, you could add whatever cartridge you want. MyIDE, SpartaDOS X, Mac/65. So I can finally use the MyIDE together with my Sample Cartridge! >>Louis Quote Link to comment Share on other sites More sharing options...
flashjazzcat Posted April 12, 2011 Share Posted April 12, 2011 Any kind of XE adaptor with two cart slots on the back would be damned handy IMO. MG makes one for the MIO, I believe (although its prime purpose is the connection of the MIO, of course). I'd also like to use a passive MyIDE cart with other carts. The 1090XL is something quite different: it was a parallel bus expansion system, for connecting hard disk interfaces and other expansion cards to the XL's PBI port on the back of the machine.

Fox-1 / mnx Posted April 12, 2011 Share Posted April 12, 2011 What about this solution? ----------------------- ----------------------- ----------------------- ----------------------- One cartridge slot in the back (or on Black Box in this case) One cartridge slot on top.

Well the first thing is to figure out what, if any additional signals are needed for new hardware ideas, etc. The IDE Plus 2.0 device has shown that the signals on the XE ECI should be the minimum starting point for any new PBI standard, since some cartridge control signals are required for devices like intSDX to operate as external devices. Any kind of XE adaptor with two cart slots on the back would be damned handy IMO. MG makes one for the MIO, I believe (although its prime purpose is the connection of the MIO, of course). I'd also like to use a passive MyIDE cart with other carts. The XE adapter MG made is a reproduction of the original ICD version which allows the MIO to be used with a 130XE. The 1200XL PBI EXTENDER BOARD he made also had the dual cartridge slots. Quote Link to comment Share on other sites More sharing options...

Did you find any problem when working with multiple cartridges? Quote Link to comment Share on other sites More sharing options...
Fox-1 / mnx Posted April 17, 2011 Share Posted April 17, 2011 Did you find any problem when working with multiple cartridges? Only with cartridges that won't work together anyways. You can't insert 2 game carts and expect it to work :-) The port on top can be switched off so can be used for Sparta-Dos 3.3 on cartridge while the other cart can be a RT-8, or USB cart, or a sampler cartridge, or whatever. Haven't checked yet if it actually works with a 1 or 8 Mbit flash-cart. Quote Link to comment Share on other sites More sharing options...

I have an original ICD adapter and it is excellent. I can use the MaxFlash versions of SDX and my repro RT-8 cart with no issues (the 8Mb version does not work with the RT-8, but the 1Mb and 1Mb + MyIDE carts do).

JohnBuell Posted September 25, 2011 Share Posted September 25, 2011 Is anybody still making cards or extensions to use multiple cartridges in an XL or XE machine? Quote Link to comment Share on other sites More sharing options...

Keatah Posted November 13, 2016 Share Posted November 13, 2016 Ohh how cool! I had no idea, absolutely no idea Atari even toyed with the idea of an expansion chassis. Let alone made them. Anyhow, this looks to be much better than the ratbag thing they made for the Apple II back in the 70's. Whatta shitbox it was. Quote Link to comment Share on other sites More sharing options...
Mechanicjay Posted November 14, 2016 Share Posted November 14, 2016 Found the 1090XL Technical Notes while browsing old comp.sys.atari.8bit threads. Fascinating! "3.0 Future Enhancements The future enhancements include a SIO card to allow operation with the current Atari 400/800 line as well as the option cards stated in the introduction. As of this document no option cards are defined." It would be pretty neat to see a reproduction of this come to pass, though without cards to actually throw into the box, the concept is kinda DOA.

kenames99 Posted June 10, 2022 Share Posted June 10, 2022 hi, I am sure everyone here has seen but there is a new 1090XL pc board design available and open to everyone. it is at I have not done any work on the chassis for this project so if anyone wants to jump on that, please do. Thanks everyone. Ken 7 1 Quote Link to comment Share on other sites More sharing options...
