TGB1718 Posted November 17, 2019 Share Posted November 17, 2019 (edited) It maps into to 4K 'hole' above 48K, I modified the left cartridge slot to accomodate it, I can't remember if it's accessable if Basic is inserted, (will pull my 800 out and check later) But I used it mainly for debugging assembler programs using BUG65, the extra 4K moved everything up nicely and gave me room to load BUG65 in higher memory. I was develping some games at the time, so needed all the RAM I could get. Just checked with BASIC inserted and it does still allow me to save data into the 4K RAM, did a poke 52000,34 ($CB20) and it read back 34. Obviously BASIC can't see this RAM so it just shows 37902 free Edited November 17, 2019 by TGB1718 Extra info 1 Quote Link to comment Share on other sites More sharing options...

Neat. Full 52K mode without a left cart present. Well, the 4K is still there above BASIC, but wont be used automatically. Good for ML routines, PM data, character sets etc without consuming regular RAM area. Im curious how extensive the mod was the re-address the right cart port.

Yes, it does that with disk BASIC, also BUG65 uses it, for some strange reason MAC65 won't use it (disk based version) Quote Link to comment Share on other sites More sharing options...
Sinjinhawke Posted November 19, 2019 Share Posted November 19, 2019 I guess this is mine. Had it since the early 90’s. The rest of mine are much more common. 1 Quote Link to comment Share on other sites More sharing options...

Gunstar Posted November 30, 2019 Share Posted November 30, 2019 I'm sure this thread topic intends rare cartridges to be production carts? I guess the rarest I have is the Super-Sketch Graphics Master cartridge that came with my Super-Sketch tablet. Other than that, I have some very limited edition home-brew's of Commando, Xenophobe and Tower Toppler. Commando and Xenophobe cartridges were purchased from Video61, but new labels were made for them along with box and manual. Tower Toppler is not from Video61, my version works flawlessly and without bugs; it was made from scratch by the person who made the boxes/labels/manuals for the other two.

+slx Posted January 21, 2022 Share Posted January 21, 2022 My rarest ones would be Coconotes, Congo Bongo and MS BASIC II, unfortunately cart only for the first two. I was astonished to see MS BASIC II listed as „8“ on Atarimania. Sorry, no pictures. Quote Link to comment Share on other sites More sharing options...
DavidD Posted January 21, 2022 Share Posted January 21, 2022 (edited) I have a copy of Bounty Bob Strikes Back -- I found it in a thrift store years ago. I thought I read something a few years ago that implied it was somewhat hard to find... Other than that, I don't think I have anything that uncommon. The weirdest looking things in my collection are probably JOURNEY TO THE PLANETS and K-RAZY ANTIKS, but I didn't think they were necessarily rare. I feel like I have a copy of Congo Bongo too. I remember playing it and I don't remember loading it off a disk. Edited January 21, 2022 by DavidD Quote Link to comment Share on other sites More sharing options...

Mclaneinc Posted January 21, 2022 Share Posted January 21, 2022 My rarest cart is my BASIC cart, it's now the only cart I have so has to be my rarest I love that Super Sketch Cart Matt, looks like a computer variant of a Sketch a Graph, a toy from the 70's (I'm so going to buy one soon as they are still made (they toy, not the cart)) Hey, it's nice to have a toy from your past.. 4 Quote Link to comment Share on other sites More sharing options...
StickJock Posted January 21, 2022 Share Posted January 21, 2022 I have a couple of boxed Super Sketch kits. I have no idea what they are worth, tho. I've never used them and I'm not sure where I got them. Quote Link to comment Share on other sites More sharing options...

mimo Posted January 21, 2022 Share Posted January 21, 2022 A rather poor condition Gibellie Firebird cart. It's rare for a reason. I did have a boxed version at one point, but as usual had to sell the stuff that was worth something. Also a really rare cart made from Lego and absolutely no idea what it is, but it's probably a "The Pill" clone? But no switch 4 2 Quote Link to comment Share on other sites More sharing options...
