    Source for purchasing a MC68851 PMMU for a Macintosh II

    I just wanted to add I did get another quote from www.ovaga.com that came in at $120. Again a bit steep, but it is another source if someone is looking for one.

    Macintosh II supporting more than 8MB of RAM issues

    I found out you need PAL SIMMs if you want to use more than 8MB of ram on the Macintosh II. There are some on Garrett's Workshop on Tindie, but are currently out of stock.

    Macintosh II supporting more than 8MB of RAM issues

    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...

    Tandy 1000 SL/2 Keyboard?

    This must be the Tandy 1000 SL I gave to a friend who gave it to you. Well anyway.... I have a couple of converters I use for my Tandy 1000 SL/2, TL/2 and TL/3 computers. Just look for the seller geralds_retro_pc on eBay. Those are the ones I have and they work without issue. There are...

    ComputerLand BC88 computer from 1986

    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...

    SimCheck INN-8448 power adapter

    Awesome, that is exactly the information I needed. I am going to order an adapter from Amazon for only $10. Mine appears to have a plug in for power on the back, if not I should be able to solder this internally with no issue...

    Pravetz-16ES 80186-8 IBM PC compatible computer from Bulgaria

    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...

    Distorted audio with new MacEffects Thunder PDS accelerator in an LC II

    The response I got back from MacEffects was that the issue is most likely due to issues with the sound chip at UB10. I checked that area with a 30x loupe and did not see any corrosion. They offered me a replacement accelerator or a refund, but I think it is something with the logic board at this...

    Distorted audio with new MacEffects Thunder PDS accelerator in an LC II

    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?

    Radeon 9200 PCI card issues in Beige Power Macintosh G3 w/OS 9.2.2

    The 2D performance of the card was extremely slow, much slower than the onboard video. The video acceleration was not working even when it was supposedly enabled. The card works just fine under OS X, so I know the card itself is just fine. It just did not play nice with OS 9.

    Radeon 9200 PCI card issues in Beige Power Macintosh G3 w/OS 9.2.2

    I finally threw in the towel trying to get the video card working on OS 9. That being the case I did the next best thing. I installed a Sapphire Radeon 7000 64MB PCI card. That is working just fine and is at least much better than the Rage Pro Turbo 6MB onboard video.
