Checksum checks out OK: 002CF656MartinB wrote: ↑Tue Jul 31, 2018 1:57 pmThe Elk-modified AMX rom that I prepared for Stuart and that he posted earlier in this thread, ('AMX' on side 2 of the posted dsd image), has a Checksum-32 of $2CF656. If you get the V4 EEPROM utilities from here, you can use the EEP16 tool to calculate and display the checksum of any installed sideways rom or ram-bank. With EEP16 on a disc, type *EEP16 SUM <n> where <n> is a single hex digit between 0-F reflecting the sideways rom or ram-bank to be checked, and the installed Checksum-32 for the given rom will be displayed. In this case, you should of course see $002CF656.
I’ve been thinking about trying UPURS instead of AP5 to prove the smallymouse works but I will have to make a real disk too.
If Neil uses UPURS to make a fresh floppy from Stuart's image post, we'll at least know for sure that all the software and firmware has been imported correctly. I wasn't suggesting that there's anything wrong with the AP5 but when one has an apparent system configuration conflict, it's always best to strip back to the minimum/basic possible config as a starting point.Duncan wrote:When I saw gobbledygook before I should have clarified the ROM was fine it was the Amx art software that was corrupt.
But if he takes AP5 out how will he use UPURS with no user port? No mention that he owns a EUP.MartinB wrote: ↑Wed Aug 01, 2018 10:06 pmIf Neil uses UPURS to make a fresh floppy from Stuart's image post, we'll at least know for sure that all the software and firmware has been imported correctly.

Ah okay you mean you built the EUP (Electron User Port) board so you do have one. That was the missing piece of information. You called it UPURS instead of EUP, hence my confusion or you would have been connecting upurs cable to air.
I knew Neil had an EUP.....Duncan wrote:That was the missing piece of information.
Ahh yes, sorry, I got the EUP last year for the UPURS function, so that’s what I call it in my head, didn’t even think about the User Port until this thread lead me down that path. All the parts have been sat in a box for over a year.
Ok, I won't hijack the thread with my own issues then but I can't get any mouse to work with the smallymouse now (it was working fine for a few weeks that's why I assumed it was the ps/2 usb mouse had failed, and that was why none of my nornal usb nice worked with it, but in the light of what you've said I see the issue must be elsewhere).simoni wrote: ↑Fri Aug 17, 2018 5:49 amSmallyMouse2 doesn't require a PS/2 compatible mouse - it has real USB support. Any mouse should work, even wireless ones.
The only hardware reason SmallyMouse wouldn't work with something (assuming the connections are correct) is power - USB requires 5V. The interface to the computer is basically analogue since it's just switching, so there is very little to go wrong (it's also proven on many (many) 8, 16 and 32 bit machines).
