This board combines the best features of currently available RC2014 memory boards in one:
- One 512K memory chip which can be RAM or ROM (selected with 3 jumpers)
- One 512K RAM chip
- Select between linear and paged memory using a single jumper
- Select between linear and paged memory in software (from Z80 or BusRaider)
- Support for the PAGE pin on the RC2014 bus (with an optional pull-up selected via a jumper)
Plays nicely with the BusRaider.
- It is recommended that you install the PAGE jumper on this board - see note below about the PAGE jumper
- The Linear/Paged jumper should be set into Paged position if you are using RomWBW and Linear position if using a Z180 with its extended addressing mode. If you are using BusRaider along with this card then you can set the jumper into Linear position as the BusRaider software can control the linear/paged function based on the machine you are emulating.
- The RAM/ROM jumper should be set into the appropriate position for the chip you are using in socket U1. All three of the RAM/ROM jumpers should be either in the RAM position (when using AS6C4008-55SIN) or ROM position (SST39SF040-70-4C-PHE).
More details of jumpers and IO addresses are in the documentation
