In know that SunOS demands parity SIMMs, sparclinux might too, but I'm
not 100% sure.
>From the hardware FAQ:
Memory consists of up to sixteen 1M (501-1408) or 4M (501-1625
or 501-1739) x 9 30-pin 80 or 100ns SIMMs, in four banks. Banks
must be filled in the order 0, 2, 1, 3, and SIMM types may not
be mixed within banks.

Without proper ram you get no video. It should show video without
keyboard being plugged in. On my LX it shows video, complains about
no input device and jumps to serial console. Unplugging the video
card will guarentee going to the serial console.

We might here (packed in a storage box currently - let me know). It
is an 8 pin DIN connector:
The pinout of the DIN-8 connector (female, on the CPU) is:
7 1 GND 5 TxDA (Keyboard)
8 6 2 GND 6 RxDA (Keyboard)
5 4 3 3 Vcc 7 TxDB (Mouse)
2 1 4 RxDB (Mouse) 8 Vcc
