    New Retro Case - A bit pricey but very clever

    This is on my wish list, I'm running old server case that I've had for the last decade or so, and it's black, but has a beige 360k and 1.44mb floppy installed (Greaseweazle), so this case will be perfect for me. I rarely use my spinning drives anymore since I have 2 nas units in the rack.

    I have a Mac SE with 6.08 loaded on it. Looking for insights and/or hardware to connect to outside world

    I've used a localtalk to ethernet adapter to get online a while back, but it wasn't work the trouble in my opinion (And that was a se30..) The bluescsi v2 (With pico w) allows for a wifi connect using MacTCP, here's the link to a guide. https://bluescsi.com/docs/WiFi-DaynaPORT

    What to do with 90 extra 27c512-120s???

    I've been on a cleaning / organizing kick lately, and I realized I still have over 100 TMS27c512-120 eproms. We used to sell these back in the day and when the orders dried up the boss sent them home with me. Are there any projects out there that call for these anymore? I've mainly switched to...

    Drop-in NEC V20 CPU Emulator with EMM and MicroSD - MCLV20_Max

    Ok, looking at your video and github, I can make just one suggestion. Add a current description of features and roadmap to the github. You don't even have a readme up. So, can you layout the following? 1. Can you use this to expand the base memory of the unit (i.e. 256k-640k) 2. You say you...

    Drop-in NEC V20 CPU Emulator with EMM and MicroSD - MCLV20_Max

    I got one of the MCL86+ boards a long time ago, is it the same board with a software update? (I also need to grab a psram chip or 2.) Also can I use a teensy 4.1 that doesn't have ethernet on this? Thanks.

    C128 black screen / blank screen

    But grabbing a deadtest / destest (Brand new diag rom) cartridge is a good idea.

    C128 black screen / blank screen

    There's actually a diag rom for the 128 that can plug straight into the motherboard at u36 if you have a spare eprom and a way to program it. C-128 Diagnostic Rev. 789010 World Of Jani (Click here)

    Any success using VICMODEMs?

    I used one of these back in the day. (Panasonic Easa-phone Va-8120) It has a l/h volume control for the handset. There is one on ebay at the moment for $21+shipping currently (That's where I stole the picture.) I only used the 1600 for a little bit, then got a 1660. (Then a volksmodem, and...

    VGA Monitor for AMIGA 3000

    This advice comes from years of working on arcade monitors, Multiple bad caps can cause you to keep chasing your tail over and over, and the cost of the caps isn't that much to just go ahead an eliminate them as the root cause, so that you can then start finding any other problems that exist.

    VGA Monitor for AMIGA 3000

    First off inspect all the capacitors, they are the main suspects in monitors. You should just go ahead and recap the monitor to see if that fixes the problems, but make sure to notice ratings/size/ and if they are bipolar caps or not.

    Looking for info to replace TRS-80 4P boot rom with 2732 eprom

    Looking here https://forum.vcfed.org/index.php?threads/model-4p-rom.65138/ It seems you need to lift out CE on pin 18 and connect it to ground, and then take pin 21 (A11), and connect it to a11 on the pcb. On the original rom A11 is pin 18, and 21 is a12, which isn't on a 2732.

    Anybody still using spinning hard disks on their newer machines?

    My daily driver has a 4tb NVME for the OS and programs I use, then 3 4tb spinners for data storage, but most of my data store is on a Unraid Box with a 90TB store.. (I keep everything... :) ). Power is pretty cheap around here, but I'm glad colder weather is finally getting here, so the AC can...
