I'm starting to think about diving down the rabbit hole of building an 8800 clone. It goes back to the first computer I was exposed to back in the 70s, which I'm fairly sure was an 8800. I learned to program in 1979 on the TRS-80 Model 1, and I have several of those....but I've never gone back...

Does anyone have any need for some? I know someone who has some that are no longer needed; I am more than happy to pass them along to you for whatever it costs me to get them from her to you. -Kevin

I have a Model 1 monitor that was working when I got it. Now, I no longer get video. I know the Model 1 I'm hooking it to is good, as it'll generate output on another monitor I have. Anyone have any troubleshooting ideas? Note that I've never worked inside a CRT display before, and I'm aware of...

I was just given a pair of Coco Deluxe joysticks, new in their boxes. I don't have a Coco and it's not on the list of things I'm likely to acquire any time soon. I'd like to get these into the hands of someone who would appreciate them, but I don't want to give them to someone who's just going...

Earlier today, I acquired an Apple ][+ from its original owner. With it, I received three drives -- two Disk II, and a 1/2 height drive of a brand I've not seen before. One Disk II works just fine, the other does not. I'll disassemble it and clean the heads sometime this weekend. Assuming a...

The instructions say to install a switch that allows you to switch modes (autoboot ROM or standard ROM). I'm looking for info on where others have placed the switch for their FreHD autoboot ROMs in Model 1s. I'm thinking that having a pigtail on the switch that allows it to be plugged...

I'm not finding a lot of information on testing to make sure a freshly installed LC mod is working properly. Since I don't have any floppies for mine, nor do I even know if the floppy drive works, I'm looking for methods that minimize the amount of other potential issues I have to bring into...

Anyone know of someone who has a copy? -Kevin

I've got my FreHD up and running on my Model 4, and it's working beautifully. The auto-boot ROM is a lovely creation. :) I'm not happy, however, with the SD card I'm using. Before going off and buying a new one, I'm looking for information on SD card compatibility. In addition, I'm curious to...

When I last put my Model 4 away, it was operating correctly and would boot from floppies. I (finally) got a FreHD and decided that before I installed the new FreHD boot ROM, I'd make sure things were working properly....but they're not. Holding down break, it'll boot into Cassette BASIC...

So...a friend and I were doing diagnostics work on my bad Expansion Interface board. Part way through, we discovered that my power supplies have both crapped out. At the same time. sigh Today I had them plugged in and in use for longer than I've run them to date, and I suspect the heat from...

I have a Model 1 that has the buffered cable modification. Can that system be used with a newer version EI that does not have the modification? I'm finding information about the differences and why the various versions exist, but I've not yet found anything about compatibility. -Kevin

So the Expansion Interface on my Model 1 doesn't appear to be working properly. First thing I want to do is thoroughly clean the card edge connectors. They're pretty gunked up and an eraser doesn't seem to be having much impact. Are there other methods recommended? -Kevin

I just managed to arrange the acquisition of a Model I in unknown condition. It has an expansion and at least two floppy drives; I don't know what else is there. I'll know more when I pick it up (should be tomorrow). I'm just a wee bit excited as the first computer I did any programming on was...

In the process of reconnecting things in my Model 4, the cable to the RS-232 board is separating. Does anyone know of a source for replacement cables? -Kevin

I recently acquired a Model 4 26-1067 that has been upgraded to dual floppies and 128K prior to my acquiring it. With both floppies connected, it does not boot. With power removed from the top floppy, it books, the bottom floppy spins but it never displays the "Diskette?" prompt. Instead, I get...
