Hi All, I need a little help ID'ing these parts. The box the CRT and dual 5.25" floppy drives were in has a label "Eagle II CP/M". This seems to match some online pictures. The other box had no label but had the 8" drive, back-plane, and cards together. The person I got these from says he think...

I would have thought this was something baked in to Win10. WOW !! Not even close ! Googling around found nothing free to rip a simple old motherboard driver CD to an ISO file !! This is simple for audio CD's But data CD's, CD-Rom's seem to be much more difficult. (at least for free) Please...

I did something bad. I dropped a screwdriver on this motherboard. It hit just right to take the top off U8 and expose the chip die inside. Needless to say this chip is dead. It is a MSL828S You can see it pretty well in the first pic here: U8 is in the upper left just behind the co=processor...

I have several of these keyboards. The coiled cables are all sticky to the feel. I am unsure how to clean them. This appears to be a issue with age. And not that something has been spilled on them. These keyboards are from many difference sources around the country. I have seen many IBM and...

I have some DOS IBM boxed Dos boxes. They have stickers for the version they contain. I have similar stickers on other boxed items. I have a couple below 2.10, 3.0 for example. Notice the pink sticker, being very closer the binder fabric. Many I have seen are like this, for 1.0 to 6.22 I want to...

I need some advice how to remove these chips without too much damage to the PCB. The card is a Everex EV-159 I have not done anything to it yet except dusting and a little rubbing with ISO. I'll remove the bracket and deal with that later. Both chips and the resistor pack are effected. There is...

My friend found this LOMAC LM-25 A computer. Or at least I think It is a computer. It appears to be a S-100 system judging from the cards. But I can not find ANY info about it online. It has 2 8" floppy drives. The backplane cage is part of a desk. Take a look at the pictures he sent me...
