Thank you for making your UPURS software available. I'm also trying it with a daveejhitchins-supplied cable and UPURS 2.0 ROM plugged into a New AP5 in a New Plus One with a New AP6 and an old Electron - but I can't get it to work.In specific answer to the AP5 question and assuming we are talking about Dave H’s new AP5, the latter not only supports UPURS but has specific connection points for both my UPURS and I2C project functions via (I think) PL1 and PL2 respectively. I think the bespoke Elk UPURS version used for the AP5 is V2.0E which includes an MCG loader
I've FTClean'ed a Windows XP computer, installed the drivers (the download was called "CDM 2.08.24 WHQL Certified"), am running Hercules SETUP Utility 3.2.8 and am able to toggle the CTS indicator. I've unplugged all unrelated ROMs and switched off the tube and MRB.
However, I get "Chunk Type" errors no matter what double-unzipped UEF file I try with *UPCFS.
And *UPLOAD R<id> yields an immediate "Transfer Ended" message yet loads nothing into any sideways RAM bank.
(I also get "Track No.>79" errors with whatever SSD file I run through *UPSSD, but I assume that's because I'm trying to write to MMFS even though the manual makes it clear the command is for physical floppy discs (which I don't have)!)
I've run through the troubleshooting pages of the manual and have tried checking the DTR box but am still stumped. Any idea what the issue could be, please?
