I picked up this computer a few years ago on eBay for only $125. It was in nearly perfect condition with some initial signs of rust on the inside of the case cover that I was able to get completely cleaned before it did any permanent damage. I vividly remember seeing this exact computer in the...

I just picked up a Macintosh SE SuperMac SpeedCard accelerator. This accelerator has a MC68000 clocked at 15.67MHz along with a MC68881 math coprocessor at the same clock speed. Finally it has 16K SRAM cache. I have been interested in getting one of these for quite some time to see just what...

This is a really cool motherboard, but is extremely finicky when it comes to hardware and software compatibility. I think I finally have this 99% solved and just wanted to share what I have found out. Intermittent parity errors: I first thought this was a memory issue, but all the ram chips...

I thought I would share my opinion if it is worth getting or not. jrIDE compatibility: It does indeed work right along side a jrIDE. I have included a screenshot from the memory timings using the Quarterdeck Manifest utility. As you can see, the fast 512K is coming from the MCL86jr. The first...

I saw the recent video about the Tandy CM-1 monitor on Adrian Black's YouTube channel. Finding out this monitor was made by Mitsubishi and was used on the PC-9801 computers, I tried the RGBtoHDMI profile for the PC-98 400 lines, but the text output blinks and the graphics mode is distorted. I am...

The Tandy 2000 uses an 80186 CPU running at 8Mhz. I was just curious how a Tandy 1000 SL with an 8Mhz NEC V30 would compare performance wise. I have managed to get a couple of working Tandy 2000s with the help of a friend. I ran a couple different benchmarks on both systems to see how they both...

These are all 2MB 30-Pin SIMMS. I am trying to find out if these are PAL SIMMs and if they would work in a Macintosh II before I make an offer to the seller. The seller said they do work in a IIsi and Color Classic. I think the answer is no, but I just want to make sure. Any help would be...

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...

I just acquired a Macintosh II. Installing 8x4M 30-pin SIMMs, I get a black screen and a sad mac tone. 8x1MB 30-pin SIMMs work just fine. It does have the FDHD upgrade but, still has the Apple AMMU installed. The ROM version is $0178 according to the info screen in SpeedOMeter. So is this a ROM...

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.

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 a MacEffects Thunder PDS accelerator. With the accelerator installed the audio is distorted. Has anyone else had this problem with an LC II and a accelerator installed? If so, any known workarounds?

I have a genuine Mac edition Radeon 9200 128MB PCI video card that I cannot get to work in this computer. I have tried all 3 PCI slots. Every set of drivers both official and patched that I have tried have the same issue. The mouse cursor moves around, but I cannot click on any menus or icons on...

I recently picked up a Macintosh Display Card 8*24 GC NuBus video card. The one thing I immediately noticed is how hot the Am29000 CPU got. I was looking for an inexpensive passive cooling solution and this is what I came up with. I found this 4 pack of aluminum coolers for $10.99 on Amazon. I...

I have a Daystar Turbo 040 33MHz accelerator that is currently not work. When putting into any one of three IIci computers I have, I just get a black screen and nothing else. I have tried swapping out the CPU for a known working one and it has not made any difference. Visual inspection shows no...
