[POLL] Maximum RAM size owned by 8-bit Atari users

[Jacques]

Hi Guys, would just like to find out what maximum amount of RAM you have at your disposal in the most equipped REAL Atari 8-bit you own.

Thanks!

[Rybags]

1088K actually - most 1 Meg upgrades are that amount on top of a 64K stock.

ed - in fact I should say 1600K since my U1Meg equipped 800XL also has VBXE

 

Also have a RAM 320XL PBI plugin and 64K internal 600XL.

U1MB installed in my 130xe (alongside dual pokey stereo and Sophia RGB graphics) I love that machine! 

[TGB1718]

I  use 2 regularly a 130XE with U1M and 800 with Incognito (not sure why I get more of a buzz when I turn to 800 on  )

[Jacques]

Myself: 1 MB (designed by Pasiu/SSG) in 800XL & 130XE, U1MB waiiting for installation on another mobo.

[flashjazzcat]

I selected 1MB (1088K), although technically a machine eqipped with U1MB, VBXE and SIDE3 has 3.5MB of RAM.

@flashjazzcat

Thank you and I think you selected correctly, since it doesn't necessarily add-up for use by Atari at the same moment

[Jacques]

I missed 192 KB option in the poll, so if someone has such maximum amount of RAM, please pick either 128 KB or 256 KB as the closest options.

My "most equipped" Atari has Rapidus, i.e. 32 MB RAM. What I have to choose?

[+DrVenkman]

My “most equipped” is either the one with an Ultimate 1MB + VBXE or the one with U1MB + SIDE3. But do those “count”? I mean, most people don’t have VBXE set up with the core to provide additional RAM, nor can the SIDE3 RAM be used easily and transparently like the banked memory in U1MB. I mean, for anyone who isn’t Jon or Candle. ?

128K, but that's because I bought my 65XE already modded like that. I'm mostly interested in classic games and A8 is not my main micro, so didn't bother with anything more than that.

Sorry, didn't mean to ignore anyone's hardware, including these cases with 16-bit CPU.
So if anyone has something not included in the POLL, please write it down here, or choose closest match (here it would be still 1MB, although it's far off 32 MB ).

64 kb thats atari with MapRAM (mmu upgrade), normally atari has 62 kb ?  https://xxl.atari.pl/mapram/

 

 

how much memory does Eclaire have because I don't know what to select

Where's the 8KB option?  ?

I don't see why it wouldn't count. If you have VBXE, U1MB, and SIDE3, the SIDE3 loader uses RAM on the cart; you might then run a cartridge demo which fills 1MB of cartridge RAM, or an XEX demo which fills 1MB of on-board RAM, and then fills 512KB of VBXE VRAM with bitmaps and XDLs. If 'PORTB' RAM had been stipulated, then only the U1MB RAM would have counted, although Rapidus' linear RAM would have also been disqualified since it requires a 65C816 CPU to access it.

 

I suspect PORTB RAM was implied in the original question, though, since AFAIK the largest PORTB RAM expansion is currently 4MB (Antonia).

source books, math, reality, and the history of expansion generally say that 4MB cannot be addressed by a PORTB.

[drac030]

Antonia offers 4 MB only either as a linear RAM or as Axlon banked RAM. PORTB is 1 MB, because 6 is the amount of bits available to select the banks (and bit 0 is not used to select banks due to known compatibility issues).

 

The poll says "Please select amount of RAM your MOST equipped 8-bit ATARI has". So my "most equipped" 65XE, which is undoubtedly an 8-bit Atari has 32 MB RAM due to the additional board installed.

 

If "amount of RAM accessible to CPU in the first 64k of the address space" was meant, then my Atari has 320k of that (or 832k couting in the VBXE video RAM )

Ah - I did not realise it employed Axlon banking. Thank you.

Question to all those people who use 800 daily, do you all have Incognito in it or you also have other Atari computers with expanded RAM? I'm surprised that there aren't any votes for stock 48KB 800s with all the users here.

LOL! I voted 1MB due to my Incognito, but since you put it that way, my 1200XL also has 1088K total, including 512K sram from Syscheck 2 and 512K sram that's also accessible to use as extended ram on the MyIDE II I also use with it. Different memory locations are used, so it is all accessible at the same time.

It's tricky...

 

My non-Incognito CTIA 800 runs on 544 KB (16KB + 16KB out of 512Kb + 16KB), plug-and-play, no HW mods. It reverses back to 48KB (for BIT3-config) in a couple of minutes, when needed. So it is a tweener...  ?

 

But then the question is about the highest-RAM equipped... and that goes to Incognito config.

[Faicuai]

64 Gigabytes ECC... just wanted to be on the safe side for Altirra and any (unforeseen) future need.

 

[Jacques]

Whoever can't find his maximum RAM-size option in the poll, please tick the closest option (just with some comment message). Thanks and sorry for inconvenience, in the end sometimes it's hard to guess all the possible configurations

You are so true about this... I am even forgetting the Turbo-Freezer's 512KB RAM, which works well through Incognito PBI, without mentioning SysCheck's own (!)

Too true, I also have a Turbo-Freezer, but since I already have either the Syscheck 2 or Incognito on both my machines I can't activate Turbo Freezer's 512K since they use the same memory addresses from what I understand, Am I wrong about this? I still have a lot to learn about all these upgrades. Can I use both Incognito extended ram and Turbo Freezer extended ram at the same time somehow? That's the nice thing about having the sram on MyIDE II cart since it can be used along with Port B upgrades. I also have The!Cart which has the 512K sram option too, IIRC.

 

But if we are talking total ram, even that which clashes, then my 800 has 1598K!
