* The notetaker has an 8-slot backplane, with the following cards in it:
* I/O Processor card (8086@8Mhz, 8259pic, 4k ROM, Keyboard UART, DAC1200 (multiplexed to 2 channels))
* Emulation Processor card (8086@5Mhz, 8259pic, 4k RAM with Parity/ECC/Syndrome logic)
* Disk/Display card (WD1791 FDC, CRT5027 CRTC, EIA UART)
* Memory Control Module \_ (buffering, refresh, and Parity/ECC/Syndrome logic lives on these boards)
* Emulation Processor card (8086@5Mhz, 8259pic, 4k of local RAM with Parity check logic)
* Disk/Display card (WD1791 FDC, CRT5027 CRTC, EIA UART, AD571 ADC, 8->1 Analog Multiplexer)
* Memory Control Module \_ (bus control, buffering, refresh, Parity/ECC/Syndrome logic lives on these boards)
* Memory Data Module /
* Memory Storage Module x2 (the 4116 DRAMs live on these boards)
* Battery Module *OR* debugger module type A or B (debugger module has an i8255 on it for alto<->notetaker comms, and allows alto to halt the cpus [type A and B can debug either the emulator cpu or the iocpu respectively] and dump registers to alto screen, etc)
