Software jumpers have a problem if there's no software. That is, when a self-booting program (game) runs on the fancy new machine, it doesn't know about the existence of any software registers that did not exist on the old machines. For certain things (like the NTSC vs PAL setting) it makes sense to have a mechanical jumper (or EEPROM) so the right values are set up at power-on. I agree there should be a way for intelligent software to later on override the defaults set by the jumpers. -- Joe Smith (408)922-6220 | SMTP: jms@tardis.tymnet.com or jms@gemini.tymnet.com BT Tymnet Tech Services | UUCP: ...!{ames,pyramid}!oliveb!tymix!tardis!jms PO Box 49019, MS-C51 | BIX: smithjoe | 12 PDP-10s still running!
