Hello all, Recently picked up a Macintosh II (Rev A, I think) and am attempting to get it setup with System 7.1 Pro. I had success installed 7.1 on a MacSD scsi emulator, but over the last week I've experienced some oddities with relation to SCSI, specifically "locking up" during writes. At...

I have two Sun Rem RAM boards, and one has RAM errors while the other one seems to work fine. I'll have to pull both out and try them in my 2/5 to see if it's an Error 45 like you've got or something else entirely. Been a few years since I paid attention to it.

For the 2/5 and 2/10, the I/O, CPU and main motherboards are all reproduced (w/ improvements) and sold by Sapient Technologies (via VintageMicros, usually). There have also been efforts to reproduce some of the boards, including memory cards, and whose KiCad files can be found on GitHub. The...

There's an app on the iPhone called "DSLR Camera" that allows you to change the shutter speed to match the refresh rate of the Lisa monitor and capture images with little to no banding. I can't recall the speed offhand, so you'll have to play with it. Didn't realize you figured out how to...

You can make one pretty easily with two DB25 connectors and the color cable of your choosing, but a crimper comes in handy here. Unless you plan on sending that cable back, just remove Pin 7 from the cable or cut it out. I find needle nose pliers work well enough to bend the pin, or some small...

Thanks for the update. My battery case does not seem interested in being opened, and rather than destroy the battery permanently, I've decided to just run on AC whenever the machine comes out to play.

It is with a heavy heart that I share our friend and mentor, Ray Arachelian (sunder), passed away this week after a hard-fought battle with cancer at the age of 51. Ray was a member of 68kmla for over fifteen years and is well known within the hobby as the creator of LisaEm – “The First Fully...

Currently researching what it will take to rebuild both the main battery and the PRAM battery in my Wallstreet PDQ/300. I've got a good feel for the PRAM battery rebuild, since the removal is documented on iFixIt and the VL batteries are still around. I'm a little more worried by the main...

FWIW, EETools recently added the TBP28L22N to its list of supported ROMs after I sacrificed a few for another project I was working on. So, if you can find someone with a TopMax you should be good to go. I have some blanks if you have the image. Feel free to PM me. 

I appreciate the tips! Upgrade to commence shortly.

Don't mean to hijack, but curious to know the details of your SSD drive(s). My TAM doesn't seem to like this mSATA/IDE adapter combo I'm workin' with.

Appreciate the update. I'd rather do away with the Mac-in-the-middle, but I'm also trying to use some powerline-ethernet adapters that may be giving me grief. 

Well, not sure what to say here other than installing 8.6 seemed to help things considerably. Currently using a switch capable of 10Mbit and another Mac with Internet Sharing enabled, as I could not get DHCP to work. Regardless, things are in a good place now, and AppleShare via home NAS works...

Hello all, I've finally gotten around to setting up my TAM after a long period in the box. I picked up an Apple Comm Slot II ethernet board about two years ago and stored it away. I've installed it in the TAM, and noticed briefly the green link light, but cannot for the life of me remember...

@Kai Robinson I’ll be your huckleberry. I have a donor board (albeit, with no known battery damage) and an underutilized Hakko FR-300. If you’re still looking for paying volunteers, lemme know.

@Trash80toHP_Mini I’ve got family in town, and limited time to work on this while they’re here. Working on buzzing out connections to compare to what you have done so far and maybe fill in the blanks. Almost done with U3; it’s a busy one! What are the chances these GALs have had their fuses...

I've considered tacking the 68000 to the Performer as a quick test, but I suspect U7 will absolutely be needed. Using an ohmmeter and visual inspection I was able to determine the following (for what it's worth): I'll try and pick up some better hardware to buzz things out more completely if...

I have not verified power at the accelerator. The only visual differences between the SE and Plus/Classic models appear to be the GAL at U7. That GAL appears to connect to the CLK line on at least the PDS and 68-pin 68000 connector. I don't have good visuals on the rest of the lines. For...

For those interested, I finished soldering the DIP64 sockets to the Performer and the SE motherboard, and connected them using 1x32 strips: Installed the RAM, reinstalled the board, closed the case, and fired it up: There was no startup sound played, only the thick, vertical lines you see...

With some spare time at hand, I've taken upon the task of determining whether or not the MicroMac Performer 68030 upgrade for the Macintosh SE can be installed directly to a DIP64 socket on the motherboard rather than the using the SE PDS slot. This would be similar to operation on a Macintosh...
