Im having trouble getting this 8088XT philips computer running cant find many information about it for example beep codes
the problem is I cant get anything on monitor, have a videocard with 9 pin and composite and the composite works but not the 9pin digital monochrome TTL
NOW IT COULD EVEN BE THE MONITOR but how can I test a TTL monitor anyway, is it waiting for a signal ?, dont have any other sistem or monitor to test.
tried 3 other 8-bit videocards nothing worked, it gives 3 short beeps two times
Do you know what kind of BIOS it uses? Everything I've found so far doesn't mention three short beeps two times, however three short beeps by itself indicates a base 64K RAM failure
Are those RAM DIPs soldered in? If not, try popping them out and see what you get.
Basically, try removing as much shit as you possibly can first, then slowly rebuild it and see if you get anything out of it.

I get this when i tried composite out on a ATI graphic card
So I think the motherboard seems fine, and it even beeps here
Caleb Stewart
These are the cards I have, on the ATI card there is a composite out that the only signal I got out of it so far,see upper pic
I already tried dip switches/jumpers but only on the ATI card which I found information on these others cant even find the info
Justin Williams
dont know , there should be a socketed chip on the motherboard that tells bios right ??
the motherboard is a PHILIPS P3105/NMS9100 if that helps
Aaron Reed
>I already tried dip switches/jumpers but only on the ATI card which I found information on these others cant even find the info
lemme fix that
I only tried combinations of dips only on the ATI card for which I found accurate info but on these other card I cant find any info
Joseph Torres
The black white dip switches might be the problem, on the motherboard, depending on video mode you might have to change them.
Justin Jones
yea but finding what a particular DIP switch does will be fun now
Its a XT comuter with no build in BIOS ,from wat I heard
Christian Scott
I think I found the dips for motherboard but someone needs to confirm
The dip switches: 1 on=8087 coprocessor not installed off=8087 coprocessor installed 2 on=one diskette drive installed \ setting of drive type is not off=two diskette drives installed / needed, bios will determine 3 mem size 4 mem size 5 on=parallel port disabled off=parallel port enabled as lpt1 6 reserved 7 on=serial port disabled off=serial port enabled as com1 8 on=fixed disk port disabled off=fixed disk port enabled at 320-323 hex The p3105 uses a XT-IDE type hard disk at this port. It can also use regular mfm hard disks with a controller card in one of the slots. When you do this, sw8 should be ON.

I also found this
W1-1: On: 8087 FPU not installed Off: 8087 FPU installed SW1-2: On: One floppy drive installed Off: Two floppy drives installed SW1-5: On: Parallel port disabled Off: Parallel port as LPT1 SW1-7: On: Serial port disabled Off: Serial port as COM1 SW1-8: On: HDD controller disabled Off: HDD controller enabled at 320h-323h
and
Then these two are for memory configuration: SW1-4 SW1-3 On On No memory On Off 256K memory Off On 512K memory Off Off 640K memory
SW1-6 is reserved.
would this have anything to do with video-cards ??

dont be a jerk and help, these things are rare as fuck,a atleast here in Europe
Dylan Collins
What are you gonna do with that thing if you fix it? Just curious
Jose Hall
im sick of all these windows 10 and 8
want to learn computers and programing bare-bone style
also got a amber monitor TTL and I really want to see that monitor work and for that I need functional videocard
Isaac Myers
anyone HELP
Easton Walker
Do you have a battery for the CMOS?
Caleb Ward
YES I have it ,removed it too see if it helped but nothing
Evan Turner
You should ask the vintage computer thread on /vr/. They might be of more help.
Isaac Martin
yea but its not very active there
might wait 2 hours for a reply
Jaxson Clark
Is the battery actually charged? I've bodged 3AAA's into my AT to replace its leaking CMOS
Nicholas Wright
This has to be the most interesting thread I've seen in a long time. OP is based.
Since the error message on the screen is looking for a bootable drive, that should mean all the system memory is good.
The picture of the mobo looks like it's missing the CR2032 battery, that's something you'll want to replace eventually.
Looks like the Philips P3105 is a cycle-perfect clone of the IBM 5150/5155/5160, looking for info from those systems may help. It was also sold as the Philips NMS9100.
What kind of beeps do you get with the ATI card, is it the same code as the other video cards? Could point to the power supply or keyboard.
Brody Sanchez
Ignore this, it looks like it's for part number 168248, not the 168238 you have.
Thomas Kelly
And the manual I linked earlier is for ATI Graphics Solution, not ATI Graphics Solution SR which you have. Shit. They have the same chipset, maybe the dip settings are the same?
Connect a floppy to it, it will probably boot fine. Your EGA monitor is probably fucked, do this:
Wyatt Edwards
maybe it will but I really want this Amber TTL monitor to work they are rear as hell, the monitor looks like new absolutely no burn in as I can see
I am starting to suspect the monitor might have a problem, how could I test the monitor ? dont have any other XT machine
but I do have a working 386 which is 16 bit, but then you have to set jumpers everywhere again to make a 8bit work in a 16bit architecture
Justin Ward
What's the model of the monitor?
Carson Nguyen
I thought XT era machines had some DIP switches to choose the monitor type, between CGA, MDA, and EGA/VGA. The BIOS has to initialize MDA and CGA cards, while VGA cards are supposed to have an onboard BIOS chip.
Jordan Lee
True, but OP's machine seems to be a custom clone without those
Blake Thomas
OP posted incorrect information about the mobo dip switches before. For XT computers, switches 5 and 6 should be turned off to select a monochrome display.
