Hello, I'm the one who cloned that card in the video. In it I mentioned someone who had another CM153, they had actually modified it for use with the CM50 like you are trying to do. The CM153 wasn't meant for use with the external power drives but you can at least feel confident it can work with...

Thanks! That's really good to know that they should be compatible. I don't know if I'll have any other way of transferring data between systems. So that will be very helpful. I definitely will not be. If there is any chance at all that retrobrighting damages plastic it's not worth the risk on...

I recently had the incredible opportunity to be able to pick up a very complete Data General Nova system set. I went into this knowing essentially nothing and did as much research has I could before buying it and picking it up. What I ended up with are a 16 slot Nova 4/X and a 9 slot microNova...

I replaced the FDC flat flex cable with a ribbon cable so it won't be a problem again in the future. It is an IDE cable so the cable's connector is 2x20 but as long as both sides are in the same row it is basically a 20 pin cable with shielding every other conductor. This did not fix the...

I have a TRS-80 Model 4 (26-1069 Late Non-Gate Array) I picked up recently as a parts/as-is unit that had the floppy drives removed and was completely dead. After removing the line filter caps, reflowing the main power connector, replacing a shorted C401 on the CRT board, and resocketing all the...

Hello, I recently have designed an adpater for the PCjr that let's you use an ATX power supply on it rather than the 18VAC external that it *should* come with. My PCjr was found without the AC PSU after after seeing the scarcity and price of them on ebay I figured there had to be better way, so...

Wow, I have that manual on the table in front of me and I didn't see that in there! There are a bunch of examples in there I'm going to be trying out now! The ASSIGN command doesn't work. The closest equivalent is ASSIGN# but that is for saving data. I omitted that part and replaced the @Dmm...

It's working great! I'm going to have a lot of fun with this. That code sets it up to measure a DC voltage between 22V and 0.001V. Then I read it back while I put the probes on a 12V source. The DMM always returns the value in x10 notation. I'll have to convert it to a decimal value manually on...

I found a local listing for a white TI-99/4A that was sold as-is stating "Does not power on". I was able to get them to do pickup and grabbed it for $25. It came with the PSU, the box /w foam, and a few of the docs. They keys all looked ok to me, they all had minor cracking though. The keys fit...

That's very relieving to know there was a much more common computer that used the same switches. I was afraid I was screwed. I'll key an eye out for a beat up beige one to part out. I don't want to take one of the pretty metal ones out of service. I'll head over there and check it out, thanks...

Yesterday I picked up an HP-86 from someone looking to give it a good home and now I'm starting the process of getting to know it. One thing I know is that I got a very complete setup: I got it with: HP 86A 64kB HP 82908A 64kB Memory Module HP 82900A CP/M System HP 82939A Serial Interface HP...

I've stumbled onto yet another computer and am trying to spec it up right now. I've got a Gateway 2000 Liberty laptop with a 486DX4-100. It's pretty jam'n. Unfortunately there seems to be very little information out there on these and definitely no parts available. I'm currently trying to give...

I've been using my datasette with my PET and a the car adapter you are talking about. I just got a cheap one from Walmart's automotive section. It fits just fine in the unit with the lid closed. If you do get one that you can't fit the cable well the lid comes off easily. Make sure to have...

I've got a Commodore 8050 that works perfectly fine but the felt pad on drive 1 is scratching any disks I put in it. I've put two layers of painters tape under the catch that sets the height to help stop the scratching. This is a pretty lazy workaround and it still just barely scratches the...

The killer poke is a side effect of a workaround to increase draw speed on older model Commodore PETs. To summarize the problem, on early PETs an undocumented pin register was set low to disable waiting for the beam to return to the top left before accessing video memory. As Commodore made...

I really didn't plan on being a vintage computer collector. I was happy with my rather robust game console collection(Atari Jaguar anyone?). But then I was given an 800XE in part because it was like the 5200. Then I saw a VIC20 for $30 in box at a local store and thought it was too good to pass...
