I recently came across a joblot of these Panavia Tornado aircraft frequency displays, according to the listing anyway. I could just about see the LED displays through the glass on the online photos and knew I had to take a gamble on them as I was sure I knew what they were. When they arrived I was quick to open one up and I was definitely not disappointed as each of these units contained two beautiful *Siemens IPD2133 hermetically sealed ceramic military spec displays, I've seen these displays before under different manufacturers and model numbers but never come across one myself so I plan to try and desolder one and fire up and have a play with it, although quite scary as these displays can cost quite a lot of money so I'll try not to break one Let me know in the comments if you've had any experience with one of these cool displays before? And yes I know taking the sticker of the eprom will potentially erase the data, but I don't plan on using these again anyway, so don't worry.

. I recently managed to acquire a piece of a rather unusual bit of British military/sonar electronics taken from a (DOWTY WAVERLEY) Digital Cassette Recorder for Passive Sonar called DICARPS. . DICARPS was a high-density digital data recording and replay system designed primarily for passive sonar data, using modified VHS cassettes as the recording medium. The system could store around 2.7 GB per cassette, with a sustained data rate of over 125 kB/s and up to 6 hours of recording time. . The piece I managed to get my hands on is part of the tape control section going off what the buttons says, and it's packed with some interesting vintage electronics. . Inside are several ceramic ICs, including a really cool Motorola MC68008LC8 microprocessor, along with some fantastic old-school HP HDSP-2002 LED displays. . #Electronics #VintageElectronics #MilitaryElectronics #vintagedisplay #LED

. I picked up another couple of these vintage Cossor radio frequency control units a while back because they were really cheap, I have five in total now (yes I'm a hoarder 😂) . Each unit has eight HP 5082-7356 LED displays, these displays have their own integrated decoder/driver IC built directly into the display itself. . The decoder logic decodes positive 8421 Binary Coded Decimal (BCD) logic inputs into characters O-9, a minus sign (-), a test state pattern, and four blank states. . Inside the units there is also a selection of vintage ceramic ICs and a really cool Melcher SMRF 51-6 which is a high reliability step-down switching mode DC-DC regulator . I'm still trying to find out exactly where these were used. The information I've found so far doesn't make it clear whether these particular units were part of an aircraft system or a ground based system, so that's something I'm hoping to uncover. . . ⚠️ If you like what you see please drop a follow to see more 👍🏻 . . . #VintageElectronics #VintageTech #CeramicIC #LEDDisplays #MilitaryElectronics
