I have scanned the User's Manual for anyone that is interested.
Got this yesterday (along with 4 others) in a lot of stuff I bought. Fresh out of the box, never been used. Even the plastic film was still over the screen when I opened the box up. This baby will work perfectly for a few projects I have. I have scanned the User's Manual for anyone that is interested.

Bull electro-mechanical keyboard. This puppy is a bit more than just vintage. When I came across it, I had no idea what it was from, or how old it was, but I suspect it goes back to the days before micro-computing. It looks like it is from the 1950s at least. It is from a punch card key punch machine similar to an IBM 526 or 26.
It has quite the complex looking connector, but I was able to find a mating one from Digikey. This should be interesting to play with. I have installed this ESDI drive in my IBM 5170. I low level formatted it, I Fdisked it and formatted with with MS-DOS 6.2 (system transferred). However the system refuses to boot from that drive for some reason.
Using a Maple MC-1175 ESDI controller with a Seagate ST4182E drive. Using an IBM 5170. Any ideas? Using Word Perfect on the IBM 5170 that I got from a friend She works like a charm. Boy does this bring back memories. Word Perfect 4.2 is what I used back in university.
A few weeks ago, I was given this IBM 5170 from a long time friend. At one point he upgraded it to a 386 and added a 3.5 inch drive and a 420 MB drive. I managed to procure an original IBM 5170 AT board but it came without any memory installed. Today the 41256 RAM chips arrived, so I finally got to test it out. Here are some photos.
This thing is just weird. It stopped working unless I pressed on the PCB, leading me to believe that the board had a crack trace somewhere. Tried to solder where it looked dicey. That didn't work. Decided to reflow solder at every point on the board I could, hoping that would fix it. In the end it seemed still pooched. Turned the thing on today, and it decides to work. Bizarre.
This is my RP1250, which is nearly identical to my RP1280 except for some minor detailing in the cover plate over the speaker I was going to remove all the components and do a thorough inspection of the board, and replace the caps. There are not many components in this radio, so its doable. However, since its working for the time being I'll put that on hold. Pictures of my Apple ][+ that I got given to me in 2000 by a work colleague. This computer was bought in 1981 and the original owner had lots of add-ons for it and several boxes of diskettes. The second Apple drive shown below was one that I picked up recently from Kemner's Surplus in PA before they closed. Originally, it came with a Mitac drive (shown below). When I was a teen, I knew other students that owned (or had access to) Commodore 64's (like myself), Vic-20's, Tandy Model-III's, Timex-Sinclair 1000's, or TI-99's to name a few. However, I didn't meet a single person that owned an Apple ][ until my first year of university in 1987. In fact that was the only one I had seen until I got this one. They were just too expensive for most people. Below are some pictures of the accessories and cards that came with the computer.
