For ROM expansions there is no problem with the ASIC, they are at different addresses. It's the same as before, just smaller and easier to assemble for me :)
I'm thinking about a RAM expansion that's ASIC compatible, but, more on that later. I have some soldering, testing and shipping to do now!

For RAM expansions please consider to fully implement RAM mode &C3 like Revaldhino did - just it case it's supposed to run with 464 / 664 computers.  :)

I plan to do things for 6128 and plus only. I don't have other hardware to test with. And what revaldinho did is fine for these usages anyway :)


But I will clearly advertise that it is not fully compatible with 464/664 to avoid any confusion.

Good to know. It's the era of CPC 6128 and 6128 Plus anyway.  ;D ;D ;D

Received my FlashGordon a few days ago and it is so good - thanks PulkoMandy.


I also tried it on my CPC464 and it works on that too. The 464 only initialises the first 8 ROM slots of course.  I've not given it much to do but the MAXAM1.5/Protext combination work just fine.


This is a great Wiki!

I think you can move the "booster" rom to slot 6 to get it to initialize the remaining roms in that, but I have not tried. I don't have a working 464 around.

It has not changed since the first post in this thread. 25€ including shipping.


All boards have been delivered for the previous batch but I can order and assemble more. It will take a few weeks to get the PCBs delivered.


I will make some slight changes to the board again to replace the jumpers with actual switches.

And for the management of ROMs you can use ROManager 2.37 (new update online) for FutureOS. See my homepage (signature).  :)

Hi, "booster" in slot 6 crashes my 464. No problem, I'll code something, test it and let you know. Thanks.

Hi there,


A new batch of 10 boards is on the way to me. I made some further changes to have DIP switches instead of jumpers to enable/disable ROMs, and some other small fixes. Still accepting orders if you need one of these!

The Booster ROM from Inicron is for the CPC6128 to provide 32 ROMs instead of 16 ROMs. It needs to be located at ROM 15.

Hi Pulko, I would please like to order one of these new units for myself. :)  The function of ROM 7 replacement is great for 6128plus.  :)

Today my FlashGordon arrived and it works great. I use it for my 6128plus, because it does provide ROM 7.
Of course I had to install a proper OS and ROManager 2.37 first. But now it's on a Mother X4 card with dxs RTC and 4 MB RAM. Put my HD20 there too and... all fine! That was lot's of fun this night. Thank you!!!

If a CPC can have 4mb of ROMs, why is it nobody has created a 4mb ROMboard yet?  perhaps a super flashgordon could support 4mb of ROM?

it will be done, for sure, and even more  :P

think about this => some emulators limit rom number to...   16!  ;D

We are limited by the size of available flash chips. Larger chips will usually be NAND flash (not directly usable on CPC, would need more electronics) and/or require 3.3V power instead of 5V. So, it would need 8 memory chips to reach 4MB. It's possible, but is it useful?


However, the FlashGordon can be used to provide either rom slots 0-31 or 32-63. So, if you have two of them, you can modify the second one, and enjoy 1MB of ROMs on your CPC (there is a track to cut and a jumper to close with some solder, on front of the board).


For larger sizes it makes sense to do something like the C4CPC. It can be a 32GB ROM expansion if you put a large enough SD card in it.

One of my CPC6128 has a 2,5 MB internal Flash ROM expansion. Well, the size to erase Flash is 64 KB, which makes it a little more different of course. But it works well. It also got 4 MB of internal RAM.


What we do need to consider is that the CPC can handle 4 MB or ROM, but the 6128plus is limited to 2 MB, because starting at ROM number &80 everything is reserved for the Cartridge (which can use a max. of 512 KB).

I think you mean the PLUS not the 6128?
