Yea. 5151 for the 5150 and 5153 for the 5162 and IBM model M and F, Spanish variant, keyboards.

I'm finally doing this. Getting rid of Atari and Amiga machines and keep my collection of Apple machines and the three IBMs that I have (5150, 5162 and PCjr). Thank you all for your thoughts and ideas.

Haven't made my mind yet, but it seems that the 5162 would be the logical choice...

Too many machines. I'm getting rid of about 80% of my collection.

Hi. I'm running low on space and some of my vintage computers will have to go. I'm really overwhelmed trying to decide which IBM PC to keep. I need to choose between a 5150 and a 5162. The 5150 is the OG but, on the other hand, the 5162 is quite rare and special. I need to tell you that I'm in...

Hi there! I decided a couple of months ago to enhance my Apple IIe. Since I had a 65C02 CPU and some 28C64 EEPROMs on hand, I unearthed the EPROM burner... When it was the time to burn the Video ROM however, I realized that I needed a 27C32. I don't have any 27C32 but as they have a similar...

I'm having issues with my Tandy 1000TX. I was first using it with a CM-11 monitor, but it is out of focus so it is really annoying. Because of that, I changed the CM-11 for an IBM 5153. However, the 5153 started to make a high frequency sound that is almost unbearable. I would really like to...

Is it possible to add 24bit address RAM expansion? I know the TX only has 8bit ISA slots, but I'm wondering if there is any CPU socket expansion piece of ingenuity out there... Thanks.

Hi guys. I have the opportunity to acquire an extremely low serial number PET 2001-8. It's a Blue label and screen trim model in very decent shape. However, it's not working and the screen only displays that classic non-working-PET garbage. How much do you think it is worth? Thanks.

I know... they are as rare as it can be... :( But, I need a complete set to replace the AppleSoft ROMs in my II... So if anyone still has some that can share... :D

Hi there! I just got an IBM 5155 in very nice condition. At first, it was really pleasant to realize that the hard drive was upgraded by a previous owner so now it runs on 32MB! :wow: However, the fact that it didn't show any sign of CGA snow was what captured my attention. So I decided to look...

Hi folks! I have a very nice Tandy 1000TX that I enjoy playing old games with. However, the Tandy CM-11 monitor is too bright, even when I lower down all brightness. This is specially annoying for the white color. What could be wrong with this old guy? Thanks.

Hi! I have this AppleColor monitor which works with my Apple IIgs. The thing is that it is out of focus. I tried the, for me scary, open bucket tuning twice and it worked for a while. But after a couple of days off it turns on completely blurry... like it doesn't likes to wake up :D I know...

Hi everyone, I was lucky to find a very nice looking and working Apple II from 1978. It has very few cosmetic issues, but there's one in particular that I would like to fix. The problem is that it is missing the top of the power key. This machine has the first type of keyboard, the one with the...

Hi there! as the title says, i'm looking for the rare SIMM modules for the IBM PS/2 30/286. I have the stock 1Mb (4x256Mb) and would like to upgrade to 2-4Mb. Thanks.
