The repairs of my #Enterprise64 continue. It can run an old 32K ROM but not a newer 64K ROM. Also it fails the RAM test. Replaced the old soldered RAM chips with new socketed ones. Same result. Main suspect now is one or more of the address lines on the PCB. Unsure how to test it, as one of the ASICs does some clever memory banking, which probably means they're not directly attached to the #z80 CPU.
I'm way out of my comfort zone here, but I'm trying to diagnose and fix a 40 year old #vintagecomputer.

Would you like to hear what the radio transmission of the game sounds like? 📻 Here's a recording for those who missed it. 🎙️ PS. You can also record the game from this video. 📹
40 years later, a game for the ZX Spectrum will be once again broadcast over FM radio! 📻 Anyone who still has a working Spectrum ZX will then be able to test the game. 🎮 Those who do not have one can do so at the museum or online. 💻
📻 We are broadcasting a ZX Spectrum game over the air in collaboration with Radio Student! This week marks Radio Student's 55th anniversary, and they were among the European stations broadcasting computer programs over the radio in the 1980s, a tradition we are reviving. The game being aired is Kontrabant 2, originally released by Radio Student in 1984. 🎮

🧠💻 This isn't just a personal organizer - this little HP 200LX (1994) means business, boasting a 7.91 MHz 80186 processor and running the MS-DOS operating system 🤩
The Tandy Portable Computer 100, was a pioneering portable computer released in 1983 by RadioShack, part of Tandy Corporation. It featured an integrated keyboard, a built-in LCD screen, and ran on four AA batteries, making it highly portable for its time. 📠💻
The MSX Philips VG-8010, a younger sibling to the more famous 8020, was released in 1985 as part of the MSX standard (despite lacking certain features like a Centronics port and expansion bus.) It was the second MSX computer from Philips 🖥️ and came with 32kB RAM, a chiclet keyboard, and two cartridge slots (missing the cover in our case).
🧼💾 An unused cleaning kit for 5.25'' and 3.5'' disk drives. The liquid, we fear, may have evaporated by now. There's also the question of whether the material in the cleaning disks is still in a condition that we'd dare bring it into contact with the drive head 😅
I finally got my hands on a USB floppy drive so I could test these! #Free to a good home: Nine Verbatim high density floppies, one Maxell high density floppy, one 3M high density floppy, and two Fujifilm high density floppies. 😀 💾 💾 💾 💾 #RetroComputing#Floppy#Disk#VintageComputer
📚🔑 This is one of the first USB flash drives - the IBM DiskOnKey - with a capacity of 8 MB, equivalent to over 5 floppy disks 💾 And yes, it still works, we tested it 😍
