I bought the hardware…I bought the software. Reading this. And wanting to run CP/M…found these images. Using the trs80gp emulator in 4P mode…Using cp22232a.zip from Montezuma Micro, as a guess.pointed to MMCPM232.DSK and replaced diskette drive0Pressed the Reset button from the File menuand… Success! Running 8-bit software on an emulated 8-bit Z80 hardware. Looking at …

Edit/re-upload Kdenlive video to YouTube
Looked at my “Kdenlive – Highlight areas on screen” YouTube Video which had 80 views. Realized I never showed the step to make the background transparent…which is rather important. So fixed it and reuploaded it, causing views to go to zero.
Using the TRS-80 4P
OK I found the hardware and it powers on. I found the software. Will 40 yo floppies read/boot? If so how long would they be reliable? I have to admit I like classic condition. I don’t like seeing classic cars with modern rims and tires. Actually the answer is no. None of my TRSDOS disks …

Found a box… Model 4P can run Model III programs too Which explains the last 2 Model III books From here. Use Thousands of Programs. Model 4P can use all Model 4 disk software. It can also run all Model III TRSDOS and LDOS disk programs (in Model III mode) without change. So a huge …
My 39 year old TRS-80 Model 4P

Maybe blank or horizontal lines…I just don’t remember. Anyway a neighbor that had a career in electronics said he would look …
3D Printing
I don’t think I’ve said anything about this before…but I’m interested in trying it someday when money is less of an issue. Seems like a strange interest for someone admittedly not very artistic/creative. But it’s a tech thing. And 3D printers are cheaper than I imagined.
PDP-11 & Heathkit
It’s about time I mention Heathkit a popular electronics kit maker…back in the day! I ran across articles about the H11 that said it was similar to a DEC PDP-11/03. I’m sure I was aware of at the time because I got their catalogs. But the fear of spending that much money without the kit …
kdenlive video compress
I think I talked about this before under the title YouTube video compress. Anyway it’s just so easy and dramatic, I’m mentioning it again. I created 9.5min video with kdenlive and it was 475MB. I simply ffmpg in and out and it reduces it to 35MB. Pretty dramatic. To my eye, I see no difference …
