Cheap RAM

It may interest somebody that 8K battery-backed RAM for a Rombox+ can be obtained for £3.00, in the form of an 8K NV RAM chip, which is a direct replacement for the 6264 but non-volatile. Cambridge Computer Science sell them at:

The possibility of running the Elk from a 12V car battery was mentioned in EUG #2, what about a Plus 3? Will that operate from 12V DC too?

If anyone has a screen dump for an OKI 20 printer in machine code, they could really help me out. It takes about one and a half hours to dump out a screen in BASIC! I've got a single density monochrome machine code dump, but I really can't get my head around the coding for a colour dump.

Can anyone tell me what the connector on the Plus 1 cartridge slot labelled ROM STB is? Most of the others are described in the Advanced User Guide but not this one. Is it FE05 address?

I don't think a Plus 3 will run on 12 volts as it requires 21 volts to power itself and the Electron. (I'd better shut up as I'm getting out of my depth here!) I don't know if John Brown has got round to tinkering with the Plus 3 yet, but if he's reading this, he might like to get involved. OKI colour dump, anyone? Cartridge slot label? Please help if you can!
