Due to lack of interest, I never re-submitted the fixed boards to my manufacturer.  I sit on too many things already, like 100 of these.

:sad:

Something like this won't move right away. It's the "Field of Dreams" effect at play here.

I thought I'd propose something, though. Once a bankswitch scheme is set, it seems difficult to change. However, I'd propose changing the hotspot range for DF and BF to 1FD0-1FEF and 1FB0-1FEF, respectively. No board changes required, just some minor changes in PLD code are needed and you free up 16-48 bytes in each bank.

I was hoping to use the largest ROM board possible for Tunnel's & Trolls as batari BASIC now supports way over 32k

 

Are there still options for 64k+ boards? 

 

UPDATE: Just PM'ed CPUWIZ.  No 64k+ w/o RAM either.

The regular AA bankswitch board supports 64k without RAM.

 

I wasn't going to do a "Melody Encore" but I'll look into it if the CPUWIZ board won't happen. If I do, this will be a through-hole deal, and there will be quite a few parts to solder on (I won't do any soldering except the ARM chip.)

Rev.B is in the house, still needs testing, just came from China about half an hour ago.  You can thank 'theloon' for this being made.  Supports SuperBanking technique, without SARA, which means no wasted bytes in the ROM space.

 

Excuse me, but I need to solder some sockets now...
