I have two spares and I bought four yesterday- I have three MTXs, an Einstein and an MSX.

Should be covered. But still, I guess the 6502 won out in the end...

Saw this today, Zilog have finally brought the Z80 line, in dip packages at least, to a halt from 14th June 2024. https://www.hackster.io/news/zilog-calls-time-on-the-venerable-z80-discontinues-the-standalone-z84c00-cpu-family-723594464754 I have a few new CMOS spares for my Z80 machines, but I gues...

That's totally fine with me, Dave.

It's an honour, TBH!

[has a quick check of the Dev MTX] There's only 6 labled chips: The 3 system ROMs The motherboard PAL replacement, currently the MTX500 GAL is fitted, there's a MTX512 version too. The MFX GAL, that has the 512K standard version fitted, there's a 384K version for Magrom compatibility testing. The M...

And why look at a different FPGA board? Down to me I’m afraid . . . . . I’ve had lots of problems with procuring the Cyclone Ii boards. There were shortages on the back of the Covid thing, but availability is improving. The biggest issue though is the variable quality of the boards from the Chinese...

True, but you mad tinkerers stick labels on anything and everything

Did your head grow heavy too?

Did you have to stop for the night ?

Actually, I was more thinking of the Boy Scout/Army song 'The Quartermaster's Store':

My eyes are dim, I cannot see
I left my specs in the WC

I did not. That photo was too indistinct and my eyes grow dim...

So.... larger FPGA with more on-board RAM leading to a full TMS99xx emulation in the FPGA?

Let's recap the clues:

You have a custom ROM that does away with Retro mode.
There's an FPGA dev board plugged into it that has a ribbon cable coming out of it, but I don't see where it connects.

Going to need more to go on, Martin, as this Sherlock is struggling.
