Picked up this 5150 today. cracked it open and found what appeared to be -256k on board - quadram expansion board with 512k on it - some sort of hard card type device.. can anyone identify it? (at least its IDE!) http://i.imgur.com/vDS9Yxnl.jpg http://i.imgur.com/ItfFbiul.jpg http://i.imgur.com/ …

thanks for the lead... i decided to crack open the machine, and lo and behold, there were some mangled chips in banks 2 and 3.. two chips were half in the socket, and one chip had half the pins broken off... 8-O Inside, i was surprised to find a hard card, so I popped that out - i bet the drive is …

I recently picked up a clean 5150. When I boot, it first shows 2004 201 then shortly after 1701 and then it goes into 40 column mode and indicates: Parity Check 1 can someone help me decipher this? I'm pretty sure at least one of the memory chips are bad, but I haven't the foggiest on how to isolate …

IMG_20170408_233427.jpg So i have a very late model IBM 5170 AT. Trying a 4.3gb Quantum Fireball and a 420mb Conner IDE drive along with a Future Domain enhanced IDE controller (with its own BIOS). So the problem i'm having is that during boot, I'll get the Future Domain BIOS message, and it'll …

Hi all. I have a later vintage 5170, (rev 3 bios i believe) that SHOULD support 1.44mb drives. However when i boot off the setup disk, it only has options for 360k/1.2mb/720k drives, no option for 1.44. I chose 720k, and sure enough it won't read 1.44mb disks. Do I need a newer version of the setup …

So i recently picked up an AT and have been trying to do a few upgrades.. totally forgot that i needed drive rails to add drives to this machine. I don't have any AT drive rails, but i managed to find these (which don't fit).. can someone ID these rails? I don't recall ever using these. They're a …

Thanks for the insight! At first I thought the missing pins were for keying but looking at a standard floppy controller pinout , pin 34 seems like it's a required pin. I've never seen a floppy connector missing this pin. I looked at the connector on the cable and there are no blocked off holes.

I'm curious how much GPU this thing can run before it becomes a bottleneck. Do you think it can handle a modern gtx1080?

thanks for the responses. Upon closer inspection, i am noticing that just about every connector on this card is missing a pin. both RS232 connectors are missing the top right pin. game port is missing top right pin. the floppy controller connector is missing the top right pin - pin 34. I've never …

Its definitely a video controller. Plugged my EGA monitor into it and it puts up a display - which is what makes this a very strange animal. it has FDD, serial, parallel, and joystick. Doesn't look like it's a video controller. Based on what I see, it's a combo mfm/rll hard drive controller with an …

thanks for your help! attached as few more pictures (pardon the dampness on some of the chips, i had just swabbed them with rubbing alcohol to clean the dust off) Filename IMG_20170123_205908.jpg File size 374.5 KiB Views 1978 views Filename IMG_20170123_205904.jpg File size 489.74 KiB Views 1978 …

IMG_20170123_181110.jpg I have it working on an RGB monitor, but can't tell if its CGA, EGA, etc (because i don't have a keyboard! aarggh!) I do know it's color, but thats all i can determine without having a working keyboard. it has connectors for serial and gameport, built in parallel port. 2nd …

Does anyone know offhand a good source for a nice clean EGA or CGA monitor? I'm trying to recreate my first PC as a kid - unfortunately the only parts of it I kept were the XT motherboard, but i'm getting there. The hardest piece to track down is a period correct monitor - even Ebay is seemingly …

thanks for the feedback. I have a mixer, so I think I can handle the audio outputs. Prices on used SC55s and SC88s are pretty close, can't make up my mind!!

I do all my vintage gaming on my primary PC via DOSBOX. I currently have an MT32 1st gen hooked up via an Emu 1x1 Midi tab USB adapter for all the classic Sierra titles I play. 1. Would a sound canvas 55 or 88 work with this setup? 2. Which one would pair best with the mt32? Are there any …
