Mam takiego Karabasa i to nawet w obudowie z gumiaka... i dla mnie idealna wersja rozwojowa byłaby z jakimś trybem TURBO kompatybilnym ze wschodnimi klonami oraz większy RAM mogący pracować w różnych standardach. Opcjonalną Betą 128 na pokładzie też bym nie pogardził 
Jeśli można by sobie tak pofantazjować 
Hehe, the main reason why there is no new karabas-128 with integrated BDI - i have no idea where to put the connector for the floppy. I really don't want to cut any extra holes in the rubber zx case.
And regarding a possibly future version of it - i thinking a lot about that, but can't combine the wishes into the one big list / idea, like:
- add 2x AY in DIP-40 to get a turbosound (ok, seems will be funny)
- add SAA1099 (but how many software uses it?)
- add 2x TLC7528 (how many games / demos that require covox / digital sample player ?)
- add CF card as internal storage (also a question, how to handle it the best way - via ESXDOS, via FATWARE or may be by something else ?)
- add DivMMC (SD card and NMI button needs some extra holes / cutouts also)
- use a bigger 5v-tolerant altera CPLD, like EPM7512 in TQFP-144 (ok, already tested with karabas-nano and buryak-pi 2019, it works fine with 5v levels)
- add a scandoubler to get a swithable 50Hz VGA output / RGB output via the mini-din connector (does it really needed ?)
- add a simple uC, like Atmega328 to handle a PS/2 keyboard and joystick (switchable between cursor / sinclair / kempston), but again, where to put the connectors ?
- add a BDI interface. the main question - where to put the floppy connector and how to provide enough power to the floppy to avoid using an extra power adapter for it
- implement a TURBO mode (ok, already tried with karabas-nano / buryak-pi 2019, seems not so hard to implement)
- implement some additional graphic modes (hires / hicolor - already played a bit with Timex Hires / Hicolor, but not sure if it really needed by someone)
- add an extra generator to implement a classic 128 timings (this will be a tricky part, because we need to emulate a contended memory and i'm not ready for this yet with only one memory IC shared between the video controller and the machine)
Regarding the extra cutouts / connectors layout, i think it's possible to use some existing layout, like ZX Omni or ZX Next. But then we all will be deeply depends on retroradioncs factory
And also, the question is still open regarding the floppy connector.
Another idea is to forget CPLD and use some more complex things, like Cyclone IV FPGA in TQFP-144 case. Then all the wishes could be placed into the FPGA. But i don't like this idea so much, because there are a lot of FPGA based clones already on the market. Why do we need this ?
It would be great to hear a real wishes from the speccy.pl community, i need to understand how to grow the project and what is more requested / expected.
There are a lot of cuty clones already, every clone is great, and i think at some point we will generate just an entropy with a new ones, nothing more
