Amiga Joke of the Century

Tuesday night I was reading up to see what it might take to revive either of my Amiga 1200’s. As it happens, both appear to have fairly common failure modes. In reading up on the dead video, I learned that it’s often on the Composite Out, but not the monitor. I bought these two systems

TU58 dump tool on Linux?

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

I have a few basic Amiga machines which hopefully will be listed soon. Also have a couple of spare keyboards. Cindy -Original Message- From: cctalk [mailto:cctalk-boun...@classiccmp.org] On Behalf Of Zane Healy via cctalk Sent: Wednesday, June 10, 2020 11:05 AM To: General Discussion:

Re: Malfunctioning VT240 - help please

OK. the keyboard is working properly as far as I can tell, data is going in and out, and I even swapped it for the keyboard on my VT220 and the same symptoms persisted. I just verified all four ROMs on the T11, and the ROM for the 8085, against the images I found on the MAME site. So far so

The really interesting thing (to me anyway) is just how it works. The cells are 3T1C (3 transistor, 1 capacitor). There’s a good diagram here: https://electronics.stackexchange.com/questions/477173/the-detailed-working-steps-of-the-dram-3t1c-cell I assumed that the photons were just

I found AmigaKit.com in the UK, are there any Amiga vendors left in the US? I need to order some parts, and not only do I not remember who I used to use in the US, I assume they’re gone. Zane

Re: Restarting Old Amiga's

use that instead - the T model looks a bit too much like a crazy mid-90's PC for my tastes (although the SCSI's nice). The 4000T has IDE! I have one of those CF card to IDE boards on a back expansion slot, allowing it to be removed. Thoughts on this, incidentally?

RE: Ever seen a Cromemco Cyclops in the wild?

Hi Tim, No problem. I'll use this as an excuse to put a want ad in cctalk: I have a working example of everything in the August 1976 Cromemco catalog EXCEPT the EXC-2 extender board on the back cover. I would really like to complete this little "sub-collection" of mine. Consequently, I would

Re: DEC Alphaserver 4100 CPU fans

If you have a model number and/or pictures, we could probably figure out a modern replacement. The biggest things to try to match would be size, CFM, voltage, and the number of wires (for any PWM control and RPM sensor). Digikey seems to have a fairly good assortment of available fans. Pat On
