This is really a limited issue since the only real useful thing written for those cards is XBII from Myarc. Some people enjoy using the ramdisk functionality of those cards but since they were volatile (no power = empty ram) they had limited usefulness for anything but temporary storage. SAMS is also volatile memory, there's no battery backup or nvram.. and it is not a ramdisk though with software you can have some ramdisk"like" functionality (see below) Kind of silly to implement the Myarc standard then, isn't it? Only the one product using it? On 2/10/2024 at 5:47 PM, arcadeshopper said: Marketing... Ha This is hobby stuff at this point if people really want something. Make it you may sell 10-100 A ram board that can be compatible with all the different memory standards for the 4a would be the game changer. Add a DSR and make it switchable for sams and myarc at least to make it xbii capable and maybe partitions as a RAM disk with backup battery or nvram .. but you better do it for the fun as the market is small and unless you make both peb and sidecar models it's even smaller It's an interesting thought though...

Tursi Posted February 12 Share Posted February 12 I wonder, how well written is XB2? Maybe it'd be easier to patch it to know AMS? (I don't know how different the Myarc 512k was) 2 Quote Link to comment Share on other sites More sharing options...

(I don't know how different the Myarc 512k was) Probably the most important thing to remember with Myarc XB-II is that development stopped before they'd shaken all of the bugs out of it. It has a lot of potential, but IIRC, some of the bugs could seriously bite you when writing complex programs. Commented source code isn't in the wild, unfortunately, so the only way to improve it now would be a careful disassembly/bug hunt. . .unless Lou Philips still has a copy of the source stashed somewhere, which would still leave the bug-hunting exercise. 3 Quote Link to comment Share on other sites More sharing options...

Look at page 23(29) of this PDF for a short synopsis of the Myarc paging scheme.

+OLD CS1 Posted February 13 Share Posted February 13 My 512k MEXP-1 also conflicts with my WHT SCSI. I am almost certain the CRU-based memory banking scheme is not responsible, but rather the RAM disk is the culprit. Quote Link to comment Share on other sites More sharing options...
Tursi Posted February 14 Share Posted February 14 19 hours ago, hhos said: Ooohh. That's very different..... Never mind. Ahh... so it swaps out the entire 32k space with two CRU control bits. That's awkward to simulate with the AMS though it could be done if we can make some ROM space for a larger paging function. But, if XB2 was never really finished and there's no pressing software that needs it, maybe it best remains a historical artifact... 1 1 Quote Link to comment Share on other sites More sharing options...

My internal 64 K expansion did that too, to begin with. But then I realized it was a bad idea, and changed to eight CRU bits each controlling 8 Kbytes of RAM being paged in or out. It's a lot easier to handle if not all your program's memory disappears for you when you switch a bank. 4 Quote Link to comment Share on other sites More sharing options...
