For those who now wish they had paid later to get the REV B1 boards.. if everyone adopted that attitude, Absolutely nobody would have purchased the first board, and the project would have likely been abandoned Being an early adopter means you're an early adopter. I have one of the early boards here...

I swapped out the -38 mmu and glue for the originals and the machine booted up just fine. So it appears there are differences between the old and current version. No idea what yet though. Now we go into rumor territory ... but I _think_ I've seen it claimed that the very first MMUs couldn't do more...

Yes, but slightly different frequency. 32.04245 MHz. 32.0424 MHz CO25944 32.04245 MHz C100281 (Mega Oscillator) 32.084988 MHz CO70176 (Falcon) 32.084988 MHz CB102275 (STE / MegaSTE PAL Oscillator) 32.215905 MHz C398097 (STE / MegaSTE / TT Oscillator) 32.21590 MHz CB102649 (Falcon Square Oscillator)...

I have also realized this thread is specifically about Falcon main clock oscillator. Should you be interested, I have a stock pile of these:

Those are not just Falcon - that's the main PAL oscillator for the whole of the ST/STE series.

I followed the Epson links through to a distributor in Germany. You need a special programmer, but it looks like they can be had in low numbers at around 2.5 EUR each.

(I didn't check for a DIL package)

Well that was quick. https://centuriontech.eu/product/customized_oscillator/ "Custom built crystal oscillator in DIL14 “metal can” packaging with output customized per your specification. Please input your desired values below. Frequency must be within 0.500MHz – 133.000MHz interval." At €7.5 it's d...

The -20 GLUE has "short top border" (PAL screen starts higher up on the TV/monitor than on the later revision)

A lot of demos will fail to remove upper border/start fullscreen on those machines.

Huel have, for a long time, insisted on adding a field not mandatory or needed for Swedish addresses to the slip. When it goes through DHL's system, they for some reason think that field is the "top" name field. I have had lengthy debates with store clerks explaining that no, my driver's license doe...

Yes - for the circuit designed above.

Interestingly enough I found Atari's part number on Alibaba for the oscillators ... now that I have a hard time believing.
