Hello, im new to the forum, im from Catalonia so english its not my native languaje, but ill try.
I've recenly picked an old Kenitec 286 plus from a dusty warehouse, but its not working at all, may be i can get some help in here...
First things first, the specs:
- 286 processor at ??mhz (since cant boot)
- Motherboard is "suntac 286-12" well not exactly, but it is the same in this post: Weird behavings SUNTAC 286 motherboard.
- Memory Unknown....may be 2 Mb or 640Kb
- HDD 20MB 5.25" ST225
- FDD 1.2MB 5.25"
- Controller card for 2 HDD and 2 FDD
- Graphics card: Peaktron electronics (CGA ¿?)
- Coaxial network card
- Monitor 14hp33t 14" monochrome, 9 pins. Dont know if its working, because computer wont start.
Now the problem. On switch on, PSU starts functioning, and leds on computer, HDD and screen turn on, but:
- No beeps at all
- No image at all
Today got some time and discovered some corrosion arround the keyboard DIN connector and battery, so i've removed both and did some cleaning. Also tested the most damaged paths, all OK.
Now i've tested the PSU giving me some high volt values:
5V -> 8V
12V -> 19V
Thats pretty high, but hey... thats ancient tecnology, may be its normal?? any ideas?
My next steps are:
- Get advide here 😁
- Buy a isa VGA card, so i can test it on a 15 pin VGA monitor.
- Test more components?¿ witch?
