Atari 800XL: Ultimate 1MB upgrade
Posted: Wed Jun 05, 2019 10:08 am
Despite upgrading my 65XE to 128kb, I still wanted more, but had always been put off the Ultimate 1MB due to it's cost.
I decided the other day to check, and was happy to see the price had dropped,so I decided to take the plunge and order one. What are the benefits of the Ultimate 1MB I hear you say?
Of particular interest were the memory options above 128K, which would allow for demos like Numen to be run.
Anyway, mine arrived today:
And I will post details of the surgery for all to see, which will see me remove my Ape Warp 32 in 1 (https://www.atarimax.com/warpos/documentation/) come out in favour of the Ultimate.
The APE Warp will then find a home in my 130XE.
More on this subject soon.
