Ah, but did you try the flash.ttp I posted here? I've seen that work for sure with rev5, whereas dfbflash.c might be targetting a different hardware configuration (I don't recall).

Hi BW. Yep. I did. Still doesn't verify. I'm using an eBay 5 for $10 CPLD though so I'm starting to suspect that. The $50 genuine one is still stuck to that faulty board I had made (the one where I skipped the two inside layers)
It's possible (I've seen some ebay chips simply have some pins not working), but the odds of it being one of the few pins that controlls the flash seems low.
4k7 will be fine. Don't change 'em if they're on there.The RAM and bus switches arrived so I've fitted that but it's not detected. I might make tonight's project to recover and fit the genuine CPLD. I also made a bit of a stuff-up and accidently ordered and fitted 4k7 resistor arrays instead of 10K. I don't know if that would cause any problems. I have the correct ones on order now.
OMG Sweet! I didn't even stop to think about whether TOS 4.x supports Alt-RAM. I guess CT60-TOS has made me take things for granted.Badwolf wrote: ↑Fri May 13, 2022 10:19 am When you say 'not detected', just to be clear, unless you're using (hardware booted!) EmuTOS, the TT-RAM isn't auto-detected. You have to run FASTRAM.PRG or MAPROM.PRG (https://github.com/agranlund/tftools) or their equivalents from the auto folder.

I'll run some tests and if all good, I think I'm going to call this DFB1r5 built and working.
That's very kind but I reckon the postage would be more than the chip. I need to put an order in when they're back in stock.The flash will be good fun once it's working. I might order a 29f400 if I can find one. I can mail you a spare 29f800 (no cost, I'll pay postage) if you'd like one for testing/development.
Posting a reply here, to this specific question.

Meantime, I have posted experimental binaries for DFB1 there if anyone finds time to try them out and report what works/doesn't.
