Hi fellas, i recently noticed that my U1MB upgraded 600XL shows some extra info while memory test is running. My U1MB has the custom firmware with PBI BIOS and booting with XL OS 1.3. Notice the extra boxes at the bottom of the test screen. Is that the extended memory check result? It will show 4 extra boxes and i thought those might be the extended memory banks.
WOW! I totally forgot about that until just seeing it now! It's showing the 4 extra 16k banks of the 130XE! I haven't seen that screen for close to twenty years! I should see it it shows up with one of my XL OS's on the 32-in1! I think I've only ever used the Self-Test under only Warp+ OS. MAN! I can't believe I forgot about that! But there was some part of me that remembered something of it, because I remember making a post asking how many rows of blocks the memory test was suppose to use, when I was working on memory issues, because 3 rows didn't "look" right to me from memory!.
Atari 800XL, 2x1200XL mobo, 1x1200XL computer:( W/ AtariMax 256/ 512K Rambo, AtariMax 32-in-1 OS, "Gumby" Dual Pokey stereo mod, Super video 2.1 mod, hi-speed SIO mod, full PAL conversion), AtariMax MyIDE 2, SuperSDX w/R-time 8 cart, Happy 1050 W/ 1050toPC and SIO2PC device and com ports, RIX video b.o.b, APE-LINK SIO extender, 1010 tape deck, 1020 plotter, 1030 modem, CX22 trackball, CX77 touch tablet, ST mouse, Wico Command Control and CX40 joystick w/Stikstand.,
XLs with a Freddie will produce the 4 bars for extended ram also
And that probably answers my question if I could get them to show up on my 256K Rambo 1200XL-no Freddy chip.
Also of note is what is still missing; it all only adds up to 112K with three rows of 16K in 1K increment blocks and then 4 16K blocks...still no test of the memory hiding under the OS! I remember this confusing me back in the day, with my 130XE, trying to figure out how they split up those little green blocks to come up with the full 128K. It actually wasn't until just a couple years ago, dealing with Rambo upgrades and extended memory tests (none of which include the memory under the OS-except one I found VERY recently) that I finally came to learn/understand why this extra 16K isn't counted in any other memory test, or is shown to be bad memory!
But now I once again own the book Mapping the Atari, and like when I owned it 30 years ago, I still haven't read/studied it and have been waiting for it all to come to me via proximity and osmosis.
Attached below is the first memory tester I found that properly accounts for a full 256K, at least, with no error or showing 240K instead. It's from 1986, and is the one I just recently came across. I *think* the second .ATR is the "backside" the first .ATR mentions on it's main menu, and it came in the sme zip folder.

This memory test (shown above) works with 65XE, 800XE and 130XE that have space for 4 chips (32k each) and a 130XE board. (It will not work with 65XE/800XE with 8 chips (8k each) nor with 130XE with 16 chips (8k each).)
Of course the 65XE and 800XE with the 130XE board do have space for four RAM chips, but only two of them are populated, you have to insert the two missing chips (and a few other components, e.g. the GAL) yourself. Alas, most if not all of the 65XE and 800XE computers with a 130XE board and space for four RAM chips were made in China and do have the faulty GTIA chip...
8bitbaz: Oh, I'm sure you did, fella. It's my memory again. I d'load these menus but I don't always git chance to go through them all: I must have a bash at these Auras though as they seem to have some cracking bits n bobs onboard. Cheers Brenski & Baker.

Baker: I thought I'd posted his site somewhere before on AS, though at that time some of the Synapse area was still "under construction" and the Electronic Novels weren't there. lots of great stuff from all over the world all categorized by country and publisher

8bitbaz: Some beauties archived-away there, mate. It's like Christmas all over again!

Baker: click on games at the top, then Synapse, then electronic novels. You will still have to get the books and manuals from Atarimania where the uncracked versions are at.

8bitbaz: Cheers, Baker. I will investigate... Many thanks

8bitbaz: Yes, we seem to have hit another spell of the 'great and the good' passing-on, Brenski. That voice of Delores was indeed something else. My Cranberries faves: Zombie, Ridiculous Thoughts and Desperate Andy...can't think why

Baker: Here you go Baz, you still need two drives with both disks in on side 1, when it comes to the password from the book it just shows the hacker's name, no password needed, just continue mrbacardi.000space.com/?i=2

8bitbaz: It's not perfect, this new shoutbox, Fred, ie. the BOLD doesn't really look much bolder than normal type and it seems to be italic by default, but I do prefer it to the original, so well done, Brenski. What do other peeps think?

8bitbaz: Baker - I'm very interested in those electronic novels - please drop me the link, buddy. Tim, you sound "snowed under" with work, mate. Drop in here for some leisure time whenever you can, fella.

8bitbaz: I'm just back from driving through a blizzard in the wilds of Holderness just east of 'Ull. Rum do. Couldn't see a damn thing: white over. Mind, thawing out there now.

timothykline: Thanks, 8bitbaz! Incredibly, I'm still pulling 50-hour work-weeks, so makes it tough to participate, much less fawn over my Atari gear. So, I try to stop by for brief visits to see what I get to miss out on.

Mclaneinc: Yes, a little confusing...

Fred_M: To be honest I think the old shoutbox was much easier to read... What do the other users think?
