Hi all,
I promised to let everyone know when we had more Dial-A-ROMs back in stock. The NEC version has been updated to support 32K banks or 64K banks, i.e. 27C256 or 27C512 EPROM types; settable with a solder jumper. Of course, you only get 8 64K banks selectable with the even dial settings. Someone requested this and it was easy enough to implement. The FLASH timing is a bit different (a bit longer from power on to first read) than an EPROM so there may be some system out there that works with an EPROM but won't work with FLASH. We have not found such a system yet, but it is possible. https://www.soigeneris.com/dial-a-rom-for-vintage-computers Jeff Birt (Hey Birt!)
