I have an old Zenith “laptop” that runs on an 80c88 processor, and apparently was manufactured around 1985. It’s quite a beast of a laptop - size and weight, rather than computing power!.
I’ve started digging for any info that will help with a fix, with not much to find on the error or generally on the computer itself. The manuals have some basic hardware descriptions, but I’ve not found any schematics or technical fault finding manuals. If anyone has any hints or tips, your advice would be much appreciated. Also, if there are any other online forums that are better for this kind of question, appreciate the info.
I’ve already posted on a retro computer forum on Facebook, with some good advice for fault finding, however the fix remains elusive, so looking to the experts on this forum for any further advice. Discussion on FB forum
Appreciate any help getting a fix for this. Thanks Rob
