So ive got a bit of catching up to do @stephen_usher but I shall get there in the end.
It's not a race. :-)
Nope, it's not, I don't think I'd be winning any races at the mo..... Maybe the one for the worst memory..... Just using your posts here as inspiration to get the enterprise working properly and with some nice upgrades.
If it ain't broke, test it to Destruction.

Yay! I have games to play on the Enterprise...

Most of them are hacked ("converted") versions of Spectrum games though... Which don't always work correctly, and often switch into an HDMI non-compliant video mode, so I have to switch to RF.

Some are hacked CPC games... Which look a lot better.

Then there is the very good software based Amstrad and Spectrum emulators though, which run full speed...

Then there are the few native games, such as the port of Yoomp, which look and sound very good.

Added code to the MiNT kernel (still there the last time I checked) + put together MiNTOS.
Collection now with added Macs, Amigas, Suns and Acorns.

So, this was the hacky version...

And now that the 74LS240 and 22V10 have arrived, the proper version...

And now begins the task of designing a case for it.

I'm going to have to read through your and @PhilC's Flan stuff before mine arrives :)

I am awaiting a batch of 5 RGB2HDMI boards so one of those will no doubt see service in it.
Collector of many retro things!
800XL and 65XE both with Ultimate1MB,VBXL/XE & PokeyMax, SIDE3, SDrive Max, 2x 1010 cassette, 2x 1050 one with Happy mod, 3x 2600 Jr, 7800 and Lynx II
Approx 20 STs, including a 520 STM, 520 STFMs, 3x Mega ST, MSTE & 2x 32 Mhz boosted STEs
Plus the rest, totalling around 50 machines including a QL, 3x BBC Model B, Electron, Spectrums, ZX81 etc...

It's analogue RGB, so make sure that you get the correct daughter board for the RGB2HDMI.

I believe it is, but I will check. Regardless I plan to use or sell the PCBs myself so If I have ordered the wrong one I can just order some more.

If you're prepared to wait for delivery about a week to ten days you can get stuff from JLCPCB very cheap, my RGB2HDMI boards came out under £5 with delivery.

First iteration of a case for the floppy interface done. Needs a bit of work to the top half, then I can work on the "floppy hat" to fit on top containing a Gotek drive.
