Now I really want to find the original Mac version so I can do a comparison of the three versions (Survival Math on Apple II, Hot Dog Stand on Mac, and Hot Dog Stand: The Works on Mac/PC).

The following announcement is from here: The Computer Museum at System Source is hosting a swap meet and warehouse sale on May 2nd and 3rd. During this event, System Source will have the warehouse open for people to purchase some of their duplicate artifacts, and help them clear some space. The...

Does anyone have a copy of Hot Dog Stand by Sunburst Communications (copyright 1991) out there? I remember playing it in middle school and would like to do a video on it... and I'm sure others would appreciate if it were archived, too. It's a black and white game where you are running a snack...

Update: Nominations are now closed. Seeing as we have only two nominations and two open board positions, it appears as if we have our new board - congratulations to @clay and @phunguss, I will be contacting you both in the next day or so to let you know what the next steps are. It’s time to put...

Do you have a IIsi? Have you tried overclocking it by replacing the 40.0000MHz oscillator at G1 with a faster one? Then let's collect our successes and failures here. I'll go first. I have a IIsi (well, four actually, but three are still broken) that I have successfully overclocked to 25MHz by...

I've seen the LCD panel upgrade available for the Macintosh SE/30, and got a crazy idea: put an LCD panel into an IBM 5155 and connect it to the internal composite output on the IBM CGA card. Or maybe the internal composite output on an ATI EGA card. Or, worst comes to worst, the VGA output on...

The motherboard likely needs to have jumper settings changed for a DX2-66 processor to work. If you post a photo of the whole motherboard, we might be able to help figure out which one it is. And if a site like The Retro Web has the motherboard listed, we might even be able to help with which...

I'm glad I found an amber CRT for my 5155 by means of a parts 5155: while the white phosphor CRT should work, it would likely encounter the same challenges as putting the amber CRT into a Mac. However, there's always the matter of that parts 5155, if I solve the case challenges (it looks like...

It is a swap meet, so presumably you would be allowed to bring an iBook to “swap”… that’s my guess, at least, I only posted this event for additional exposure (I’m one of the vendors.)

On August 24, 2025, the Retro Bits and Bytes Indoors Swap Meet will be held at the Dulles South Recreation and Community Center from 1:30-6PM. General Admission is $5 and includes a beverage and a raffle ticket for a SONY VIAO vintage computer. Kids under 10 are free. (I will be attending as a...

I just found switch settings for the Belkin F3H1381... both versions. Hopefully this helps someone with this adapter, especially because some places have only one of the two manuals. One version of the Belkin F3H1381 does not have a rotary knob, and this version is configured as follows...

I’ve been told that the 10MB limit is in the ASIC itself, which would mean that it would not be possible to overcome the limit with an extension. There was a PDS accelerator card that allowed more than 10MB of RAM, but that extra RAM was on the PDS card, allowing it to bypass the ASIC on the...

The LC II is compatible with standard 30-pin SIMMs that are rated 100ns or faster (-10 or smaller for the timing). The LC II doesn’t do parity, but the extra chip shouldn’t be an issue. I always suspect memory first: Try running Snooper 2 (not the Emergency Disk version) after booting with...

I usually use this book (Apple II Plus/IIe Troubleshooting & Repair Guide) as a starting point in troubleshooting. Given how throughly you've gone through the system reseating items, you might have a component failure.

DOS Fox told me that the Cisco 34-0874-01 power brick is another candidate for making an Atari 520ST power supply. Might be good to keep in mind if you have friends in IT, or if you have access to a cheap source. It’s rated for 3A @ 5V, 2A @ 12V, 0.2A @ -12V, and a maximum of 30W. This is...
