CPCISA

Support for ISA cards.

About the drivers (contained in the ISA-ROM v0.3)...

  • The CPCISA v2.1 firmware is completed. It accomplishes all the job for selecting mapping (port or RAM page mapping, ISA window, etc.) and configuring interrupts (IRQ) for the ISA drivers. By the way, any new version on the CPCISA Card (even with different mapping modes) will be supported by the ISA drivers without the need of rewritting them.
  • The serial/ps2 mouse driver is working for years (it uses interrupts of course).
  • The Soundblaster OPL module driver works (it can play SADT2 musics for example) but is not finished.
  • The Soundblaster sampling module works (in 8 bits mode only, 16 bits mode needs DMA capabilities) but is not included in the current ISA- ROM version.
  • The IDE Driver is working in non-interrupt mode and supports LBA. We need to improve it, the current version was just a try. The CPCISA Card doesn't have DMA capabilities so the driver max transfert rate is about 100kb/sec (using the wonderfull RAM page mapping mode of the CPCISA). Some tries with the atapi commands worked too (we can pilot a CDROM for playing CDDA).
  • Ethernet driver is planed.
  • etc.

CPCISA by Yarek

I'm going to make CPCISA compatibile bridge interface that will connect standard PC AT 286/386SX motherboard to CPC. (I will try to test also 386DX, 486 and higher but I cannot guarantee they will be useful.) Please collect the motherboards and ISA cards and be patient a bit.
