8 inch floppies, decaying

Hi folks, Tonight I got my imaging PC to successfully read some of the 8” disks from my CPT8500 word processor using one of its own Tandon TM848-01 drives, sadly it seems the boot disk is toast but I’ve been able to dump some of the data disks as well as the Utilities. Since I have a box of

Strange Teledisk question

Hi folks, For the last few weeks I’ve been helping the owner of a PPG2.2 synthesizer get the ‘computer’ side of it, a Waveterm A, running. The Waveterm is a 6809-based single board computer running FLEX that was designed to use 8” drives, then at some point they modified it slightly to use

Weird Lear-Siegler ADM-3A board

Hi folks, A friend of mine has said ADM-3A and is baffled by the tiny board it contains, not the usual ‘covering entire base’ discrete logic board they normally have. Centre of this board is the Nat Semi NS405 ‘display processor on a chip’ which is obviously why the board is so small but

I used to be site engineer at A Well Known British Newspaper printers, they have those little DGs controlling part of the press process. This was back in 2004, I was down there again last year to fix some old HP servers and those little DGs are still going strong. -- adrian/witchy Owner of
