I did some checking and was able to find a reliable source for purchasing one of these. I did find one other source but it was double the cost. Here is the weblink for a company in the Netherlands. Origineel Motorola XC68851RC16 MC68851 – Van Dijken Elektronica You cannot purchase directly...

A big problem I have had was finding a modern Tandy SmartWatch replacement for my Tandy 1000 SL/2. The Tandy 1000 SmartWatch+ from Cybernetic Systems on Tindie is too long because of the way the ROM socket is right up against the drive bays. I had been using a small ISA RTC that I bought a few...

I just acquired a Macintosh II. I am looking for a MC68851 PMMU to get 32-bit mode and virtual memory capability. If anyone has one for sale please send me a PM. Thanks!

I was just wondering if there is a RGBtoHDMI profile for the Tandy 2000 640x400 color mode instead of using a CM-1 monitor? It would be nice to take the monitor out from time to time, but I would rather put less hours on it and use the RGBtoHDMI instead.

I decided to give this a try to see how well it works. After a little trial and error I can say this is a really cool option if you have writable memory between 640K-1MB. I tried it out in my NuXT v2.0 motherboard which has UMBs enabled for C800-DFFF. I specified C800 as the start address in the...

I bought a NuXT v2.0 motherboard back in April 2020. It has worked with no issues since I have gotten it. All of the sudden the 8087 math coprocessor is not working. It is as if it is not even plugged into the socket. Now I now the 8087 itself is Ok, since I have tried it in another computer and...

I recently picked up this computer at the local FreeGeek Twin Cities for only $120. You don't see these too often. It was ComputerLand's first house brand computer released in 1986. It was manufactured by Sambo Computer in Korea where it was sold as the TrimGem 88. What made this computer...

I am looking for a power adapter for a SimCheck INN-8448 ram tester. I believe it takes a E87297 Plug-In Class 2 Transformer. Does anyone know a specific source for getting this? I have seen different variations online I am not sure which one to purchase.

Looking for one of these for my Tandy 2000.

Does anyone know the size of the two front cases screws on the Tandy 1000A? I need to get two replacements screws for the case.

I am in the process of acquiring this computer from a seller in Bulgaria. I have only read about Pravetz computers, but what I found so interesting about this one is that is IBM PC compatible with a 80186-8 CPU. The computer is listed as in perfect working condition. I am very anxious to get it...

I just picked up this EGA video card. I have been unable to find any documentation for it. It has SPEGA-00 Rev 1.2 silk screened along the bottom. I think it may be a Sigma Designs card. Any help would be appreciated, specifically the 4 dip switch settings for this card. Thanks!
