This is interesting. I have an a500 trapdoor expansion on the way but I may try and build a clone with modern parts. e: looks like this was done recently http://www.techtravels.org/amiga/amigablog/?page_id=942 Anyway, sorry for derailing this thread.

Cheers :thumbsup:So the DRAM is replaced by SRAM, I guess the GAL takes care of the different modes of addressing. I wonder if this could be done for other Amigas.

These are made with modern memory chips and a single GAL? Could you read off the part number on the memory ICs, if you don't mind?

I'm going to take next in line if things fall through.

That's interesting, thanks. :thumbsup: I might ask someone with access to IPC standards to see if this is covered, I wonder if someone has determined if it's necessary to neutralize before cleaning.

The IPA won't neutralize it, but it will displace it, though you might need some elbow grease too. I'm not too convinced that acid could seep into internal layers as it's almost always a surface corrosion effect and the epoxy and fibreglass don't seem to effected by it. I've never seen any...

What's the reasoning behind using lemon juice if you clean the board with IPA anyway? A good scrub with IPA and a rinse should remove any acid. I've done some repairs where capacitors had leaked and started to corrode some traces, I just dipped in 99% IPA, scrubbed, rinsed with de-ionised water...

I just flashed one and put it in an A500 last night and I think I may just get some longer cables and run them out the floppy opening. You really do need access to the buttons. Otherwise it's great.

There is a replacement firmware here https://github.com/radiomanV/TL866 but it is very early in development. There is mention of support for 27c4001 and 27c4000 devices, I don't know about 27c400. The hardware is certainly capable of it, but like with most programmers someone has to implement...

I have a TL866 that I bought on eBay that I really like, USB and works on Windows 7/8. They are available with adapters and 3rd party software is also starting to appear.

It's not open source, the release is not licensed for any kind of re-use. I don't think the archive can even be legally re-hosted on another server.

Still searchin' :)

I realise that these are available on eBay, but I thought I would check if anyone is selling one used for a better price. Let me know!

Sorry, forgot to ask if this came with a PSU? Thanks for checking postage costs.

I'm interested in the unboxed 64c if it's still available, how much would it cost to post to Dublin?
