![Another broken Mac Plus with some odd symptoms
On the channel today we have a broken Mac Plus machine which is a come-back. This is a machine I had previously worked on and given to a friend, but it was returned to me broken. Can you guess whats wrong with it based on the symptoms?
Unrelated, it seems like a bunch of other channels ha4ve been fixing Mac Plus machines as well, but I can assure you this is complete coincidence. (I had actually worked on this machine before those other videos came out.) So lets fix this busted Mac, hopefully once and for all!

![Lets fix a dead VARTA ravaged 486 motherboard
#repair
If you are into retro computer from the late 80s and into the 90s, you are probably fully aware of how destructive the NiCD VARTA batteries are to these systems when they leak ... and this 486 motherboard had one such battery leak and cause some severe damage to the motherboard.
So, lets try to get this motherboard working again to keep it out of the recycle bin!

Patron stynx found this about the Orchid Turbo Graphics card: Orchid Technology. The Turbo Graphics Controller (TGC), which is functionally compatible with the IBM Professional Graphics Controller, runs 4 to 25 times faster than IBM’s product. The TGC offers 640-by-480 pixel display resolution and can run on a less expensive display than IBM’s. It writes directly to screen memory (bit-map), and has RAM designed specially for video applications. Approximately $2,000.

Nick Griebel found that a Computer chronicles episode makes a reference to TOP technology, and kind of describes how you can transfer IBM files to an Apple via Appletalk and TOPS. https://youtu.be/lyHm8u_AR30?t=180
