Hi John, thank you for your reply.
Well that explains why each terminal is seperate, hehe.
OK, good to know. I'd wondered if any app developers had produced 'cassette' apps for iOS et. al. that can audibly play data tape files for use in old 8 bit systems.
Makes sense. Yep, am aware of how to discharge a CRT anode and still have a pair of old kangaroo leather motorcycle gloves that I'd wear when working on live tube guitar amps ;-) The fragility of CRTs does bother me a little. I'm kinda hopeful it powers on file and I can just get away with a hearty blast of compressed air to clean the innards.
It is quite a bit! I think the Repository already has everything I have, but if I come across anything not covered I'll be sure to scan it and make it available.
Me too! The modifications seem rather extensive, across both boards. I'll see if I can get hold of the previous owner (he left our company a couple of years ago) and find out more.

Quote:1) That's not a 9V battery holder. It's for the battery backed up SRAM and uses a special type of battery. (I have one Core board like that somewhere in my stash). It's apparently a camera battery and supplied 4.5V.

Quote:2) Neither unit has a DRAM / Floppydrive "Core" board so Gotek is out for now. Not the end of the world. You can either get a new Core board or just stick to tape input. (This is how I ran my machines before I flipped one of my SRAM Core boards out for a DRAM Core board.) I have found playing back audio files from an old smartphone takes a bit of effort to get the volume dialled in but otherwise works fine.

Quote:3) The switch on the monitor has probably failed. A lot from that era have. (Commodore monitors of that era are particularly notorious for it)
4) Just really be careful if you decide to work in the monitor. Even if off, the tubes can reaccumulate a charge and they are not fun if you accidentally short them. I used to service CRTs for a living and they still scare me.

Quote:5) That's a GREAT bundle of documentation there!

Quote:6) I'd love to know what all the mods to the second core board are for. I'm guessing something to do with all the RAM in there.
