As previously mentioned the DUALTOS 1.04 & 1.02 16bit TOS ROMs are now discontinued.They are available until stocks are exhausted.

Listed stock levels below are correct at the time of publishing this message. Other languages have already sold out and will be removed from the store.

English https://www.exxosforum.co.uk/atari/store2/#0042 (7 In stock)
German https://www.exxosforum.co.uk/atari/store2/#0127 (7 In stock)
Spanish https://www.exxosforum.co.uk/atari/store2/#0130 (3 In stock)
Swedish https://www.exxosforum.co.uk/atari/store2/#0129 (1 In stock)

In part because it is more favourable these days to have 104 & 206 ROM. But also because of the rise in costs and problems obtaining these ROMs. It is just not viable to keep every combination in stock any longer unfortunately.

I do have a small stock left of ROMs but unfortunately I fear they are not going to last long. So either they simply become discontinued until they are manufactured again ( which could probably be never at this rate) or if they are obtainable the price could be double what they are now. In which case I may not be able to stock them anyway.

FALCON 14MB INTEGRATED RAM BOARD

I have decided just to discontinue this series of board. Mostly due to the Falcon's killing certain DRAM chips. All relating to tests done in my blog
https://www.exxosforum.co.uk/forum/view ... 180#p93087

While I did develop a noise immune board I later found there was also some noise on other signals which would also need addressing. Unfortunately this would result in another re-spin of the board. But the main problem is that failures always seem to be intermittent. So it is difficult to diagnose if the noise immune board was really helping or not without a significant investigation. I am not really motivated, or have the time or patience, for spending countless months investigating and diagnosing all these stupid faults on these machines any more.

The original board which uses a 72pinn simm is still on sale and there is still a fair few of them in stock and partly assembled in my workshop. It was actually why I developed this particular board so the DRAM could be changed easily as its a 72pin simm, because a lot of original Falcon memory board failed in exactly the same way. At least with a plug-in solution if the simm does fail, then it can be easily exchanged without buying a complete new board.

Also, because sales of these have gone extremely low over the past few years then there are simply no funds in that project to continue its development any more unfortunately. I'm basically just having to write off the few remaining integrated boards and I still have a lot of capital tied up in the plug-in boards anyway.

But in any case this plug-in boards are still available for the time being.
