GSB-V2 for EV4 slotexpander

A new version of the GSB (Generador de Slots Advanced type B) for the EV4 slotexpander is now available. The EV4 is a special slotexpander that also can expand slot #0 and #3. On top of that the EV4 supports mapped SRAM. The GSB is the slot signals generator card for the EV4. The first versions of the EV4 and GSB were sold about 2 years ago. Now there is a new version of the GSB with several interesting improvements. The GSB-V2 contains 512K FlashROM and 512KB 20ns SRAM. The FlashROM is seen by the Z80 as 8 block ofs 64KB, in expanded slots #0.0 - 0.3 and #3.0 - 3.3. The SRAM is a standard 16KB mapper allocated in one of this expanded slots. This configuration is similar to the internal configuration of MSX2 or turboR systems. For additional information you can mail to lpadial@teleline.es.
