I'm running out of room in the Falcon ROM now :lol:

The buffer underrun on the CPU is a speed limitation of ROM access... if only it ran faster...

@exxos Can't you use the Hitachi EPROMs for this rather than OTP ROMs (Microchip/Armel) to save a bit of cost?

You still have them listed in your store ;)

Edit - I'll be interested in the final version for my Falcon too (if/when it breaks again)... :roll:

Yeah, but I spend more time trying to straighten the pins on the things than anything.. and I get in a bother as I don't know if the code is broken or the ROM is not making good contact.

I keep trying to find some better EPROMs, but not had any luck so far :(

Most likely make the end posts out of metal.. because.. reasons.. :lol:

Possible if the socket pins bend a bit, the wires can flow more at 45 deg and can then get some heat shrink tubing over them. Failing that, might have to resort to liquid bodge tape or resin :lol:

Are you planning to use a relay for the 030/060 switch or how is that going to be solved?

Can't you boot from the cartridge port? Then you could use cheap UV Eproms or a Sidecartridge.

Btw, this would be a really nice project. There's a ton of solutions for putting replacement chips/PCBs into ST/STE sockets but when it comes to Falcon, zero. So anyone with Falcon is stuck with the stock ROM and yeah, when you are investigating a broken machine, wiring up CT60 (to use its flash from) and wait for it to take the lead in booting is quite pointless...
