Probably because we're all old buggers.
I'm certainly an old bugger :)

I think I have PCBs left. The FT232H modules are about £6-7 including delivery.
If you have some PCBs available, I'd be interested in one (which can go with your EPROM emulators when I finally work out how many of what I actually need... :roll: :? )

I had to burn a eprom for a macintosh classic the other day after spending all day looking for my uv lamp 🔦
But I did win

Take a look at the stardot threads...

@cmorley

I'd definitely like a PCB, please, as well as one of your 64KB sideways EPROM kits too please. If you can let me know the total cost inc shipping by PM I'll Paypal you the funds.

I still have your details in Paypal so should be nice and quick.

Is there any specific FT232H module you'd recommend?

Yaaaay!

BTW one of Mr Morleys ROM emulators may be useful for you.

I would love a a eprom emulator that does the MCM68766 but can be programed in a 2764 socket
And a 2532 emulator that can be programed in a 2732

That would make me smile 😃

Ooh, that sounds interesting...I have the Solidisk Sideways ROM/RAM kit for my original Beeb somewhere...but a more modern (and reliable) alternative would be good.

Another item to add to the wish list.... ;)

27C400 has a /BYTE pin so works in 8-bit mode. A pinout adapter should work in pretty much any gear assuming you have the physical space for the 40 pin module + adapter. I did an adapter for the 1Mbit mask ROM in an Acorn Master for example.

The PCB is designed to take the "CJMCU" one. Presumably because people have been searching for that term the helpful eBay sellers are selling a smaller module with different pinout under the same code now. There is a photo in the stardot thread of the correct one.
