Re: Malfunctioning VT240 - help please

One trick I found with the -5V if it is driven by  a charge pump: check the voltage. If it is being pulled down since the charge pump cannot supply the current, just disconnect the charge pump and put a lab supply in its place.  The increased current will clean out whatever is shorting it to

Is there anyone that has already built a tool to dump TU58-tapes on a Linux machine? I have the drive of course. There is PUTR. But it is DOS only and is written in assembler so it cannot be ported easily. The other option is running RT11 on a PDP-11, but then there is the hassle of getting the

You are glossing over the fact Amiga users are technically 3/5ths of a person by law. Unfortunate but that also means Amiga user's opinions are 3/5ths important by extension. International law is very clear on this. Sorry. :) -A On 2020-06-10 12:54, John Foust via cctalk wrote:

I think you might be subscribed to both cctalk and cctech. So you get the cctalk message immediately, and the cctech one when it's moderated. At the moment the lists are largely the same since everyone is good at not posting off-topic stuff. On 11/06/20 11:01 am, Johan Helsingius via cctech
