Amiga 1200 has IDE on motherboard (using a 44-pin IDE connector), not SCSI. Are you sure you have a correct drive?

Re: IBM L40SX external keypad cable/pinout + RAM question
Posted on 2022-02-01, 20:41
Thanks! I tried a Covox clone on my L40, too! At the moment it was the easiest machine with a parallel port to dig up! Works, but had to keep the sample rate pretty low. I also have a RS232 Wifi modem, which I quickly tested in Windows 3.1's Terminal, cool stuff! With baud rates low enough, the …

Thanks! Ah, it appears I forgot to update on my progress here (I posted on several forums about the cable pinout). I eventually solved all the issues I had. I friendly Redditor sent me a pinout for the external numpad cable and I posted it on reddit: https://www.reddit.com/r/retrobattlestations/ …

99%+ of ISA slots you'll be putting an Adlib in will have phosphor bronze mating pins. It is corrosion/oxidation tolerant to lead and tin -- of course tin because it is partly made of tin itself. Also, lead is often melted in with it on purpose to give it better casting ability and flexible …

Oh, ok. As I will probably be swapping the cards around, guess I won't be using these after all. I don't want to ruin any of my ISA slots nor the new board! I didn't like the fact that the replica didn't have an AdLib logo, so I guess I'll add it myself (with a clear marking that it is a replica, …

PCB card-edge connector gold plating

Hi. I ordered some PCBs of the AdLib replica board from PCBway. But due to my newbieness in these matters, I ordered the boards without the gold-plating on the card egde connector (they are beveled though). So now have five of these boards (and soon all the components needed) and I am wondering …

If you go with hubs, I've seen this come up in second-hand market quite often: 8-port CentreCom MR820TR (pic: https://commons.wikimedia.org/wiki/File:AlliedTelesis_Hub_MR820TR.jpg ). I think it looks very nicely 90's techy and the "network load" indicator (in addition to the collision light, which …

MIDI-file players for modern macOS?
Posted on 2021-01-19, 16:47
Hiya. Ok, I have a Roland SC-55 and a Roland UM-One MkII USB-MIDI interface. From time to time, I would just like to connect the SC55 to my MacBook (running Big Sur) and play some MIDI files. Are there any good players for just basic playback of MIDI files? So far I have only found MIDITrail, but it …

IIRC you need a 256kbytes rom so a 27C020 and variants will work fine Thanks for this, and other pieces of information on this thread! I just updated my SC55 MkI from 1.20 to 1.21 ROM (using a 27C020). I am not expecting to ever notice the fixes, but I thought why not go all the way and do the …

I received the part from keropi today, and I just fitted the part in. Very nice - looking like new again! I also replaced the front-panel switches as some of those were in pretty much non-working condition. https://i.postimg.cc/56D7PbHK/20190925-180609.jpg My unit is now one of those ultra-rare …

Hi! I have an IBM L40SX laptop. I have been doing some repairs on it, I have replaced the hard disk with an CF card (I even managed to get the old drive unstuck and grab the files) and have replaced the CMOS battery so I don't have to use the config disk on every boot. I am also thinking of …

Hi! I have recently bought my first Roland SC-55. I just finished replacing the front panel switches as they were having serious contact issues (just like in AkBKukU's video here: https://www.youtube.com/watch?v=dBseVsGzx7M). The unit is working very nicely now, but it has a small visual defect; …
