Build protection and defence

Great project and looks like your pieces are in good restoreable condition, plus you are starting with 64K of RAM; good for you. The used price, in general, of H8's have come up in the last 2 - 3 years. Probably due, in part, of the HIGH cost of clean Altair and IMSAI systems. I built my first H8 while in college and have since acquired 4 other H8's over the years in all sorts of configurations. I am a retired employee of DEC and was there from the PDP8 series through the VAX 8000 and the beginning of the Alpha series; what an amazing company to work for!!! No idea what your electronics background might be but the tantalum caps are the biggest issue. Whenever I have one fail, I swap all of them on the board while I have it out. You already mentioned the issue with some oxidation on some of the IC pins. That will mostly clean up with foam brush and contact cleaner as well. Sometimes, depending how bad the oxidation is, you may need to CAREFULLY pull that IC(s) out and clean the pins with an exacto blade.. The IC sockets Heath used are not great and I have swapped many of them out with Au plated round pin type and will change most out over time As far as having the NON Au connectors, I would not worry too much with that. Once you go through and clean things up, get a good contact cleaner and wipe all of the pins with a foam swap and shoot some into the female connectors. I doubt you'll have any issues for years. I use to use deoxit but in the last couple of years, the WD40 line of chemicals now includes a great Contact Cleaner, zero residue. It's half the price of Deoxit and each can has ~twice the volume; it works very well. Most any auto store has this in stock. Good luck with your project and if you need any help, email me: glenn@dsmlabs.com

For octal, you just need 0 to 7 (not 9) 😁 The "controller board" is the hard-sectored controller typically used with the H-17. It is also possible to use the H-17 external drives with the H-37 soft-sectored controller to get about 180k per drive.

Let's see... You attended VCF West, which is in the South Bay Area. You used a PDP 8/E system in high school in the late Seventies. Did you have Mrs. Kurzweil? She's the one who got DEC to donate that system to our high school. I had her for both Intro to Computing and Intro to Typing in '76.

Power and Control

Great video, I made number 85 a few weeks ago! My main complaint is that the new pieces don’t lock into place, so they end up coming loose when you spin the saber for a second. Shouldn’t be hard for them to do better with that

And i scrap old radio..and anything electronic.

I have a:100-in-1 electronic project kit from science fair.😊from the tandy co. For Radio Shack.

I got started in electronics when I was 14 i think. I got one of those 200 in 1 science fair kits. I got into CB and ham radio. Now I find myself building kits for the kids and teaching them to solder. They think it's amazing that I build kits, fix microwaves, computers, plumbing, cars. Everything is so interconnected. I'm so glad that I grew up when I did. They don't believe me when I tell them we didn't have cable TV, computers, Internet, cell phones, digital cameras, GPS, high speed Internet etc. I shouted at you to put in the pic but I think my microphone was broken. Lol

I want a TRS80 Model I computer restomod.

They should just keep both and give you more options because the price increases for only2-3 out of the 4 looking good is not acceptable when previously all 4 looked great

90 is the first one I made. Looking forward to building another on my next trip.

I see this as a lightsaber bace that you can buy different parts(aftermarket) and really make it your own not just a Disney preset(80) is the way to got for me

ya its normal

35 is my current one

42 is my Saber With a green kyber crystal

I’m building a sabre tomorrow and this is exactly what I needed to help me decide, thank you!

What is the model of the TV that is connected to your CoCo2? The display quality is superb, even with RF!

What a nice CoCo1! Congrats! And I'm curious how come its video output is so clear and sharp. You mentioned that you used RF to channel 3 , right? I recently got a CoCo2, but its video output is a bit blurry.

In my opinion, they look ugly.I kind of like the old ones better when Galaxy edge first came out

Number 95 is my favourite, looks really clean. I like how the design lines up and has the grip at the top. Can't wait to go and build my own later this year!

Thank you so much for this! I’m building my first tomorrow, and didn’t want to be overwhelmed by having to make a choice in such a short period of time. Now I can pause this and look at exactly what I’d want!

Not me screenshotting every configuration so i can pre plan my build

I built a Peace and Justice saber back in 2021 when I went for the 50th anniversary. I have to say I'm really not a fan of the 2nd Gen P&J and Elemental Nature compared to what was there previously. On the other hand, I think Power and Control and Protection and Defense are improved over their 1st gen Counterparts. I'm not sure I'll ever build another one but it was a really cool experience to do once and I'm happy with the P&J Saber that I built.

You can get a good chunk of the RAM back from Extended BASIC by doing a PCLEAR 1. By default Extended BASIC reserves 6144 bytes of RAM for 1 page of he largest graphics modes (either PMODE 3 OR PMODE 4), which is a 4 page (each page is 1.5K) graphics mode. If you don't need high res graphics (or at least not that high res), PCLEAR can return some of that RAM.

How are you changing a 24 pin rom with a 28 pin?

Great work! 🎉

#75 is my favorite! Great job and thanks for the insight!

First thing you didn't do right was to RESEAT the keyboard connector.

I love seeing Color Computer 2s being used. Grew up in my formative years with one and feel like I know every nook and cranny of it. Had a lot of second hand peripherals because my dad would bring home prototypes or salvage from Tandy when he worked there.

5th

I had one of them when I was a kid

Good video and work

Would be total of 1536? If you combine all for types of sabers with kyber crystals?

7:17 No. 34 customize lightsaber is my favourite once I return to Disneyland in Orlando, I gonna made almost like Luke or Cal or like Rey make this

A staff you say at the end. Do you mean like a double lightsaber like Dart Maul's, or do they have a staff too. Probably a stupid question, but I feel like I had to ask.

Oh boo hoo…geez people just whine…

woo hoo like 100!!!

This is exactly what I’ve been looking for! Thanks for this video!

This is indeed a fairly early example. The earliest serial numbers start with "S" which includes the very early silver labels. The "S" designation (Stands for Santa Clara, CA) only went up to 100,000 at which point they switched to "P" (West Chester, PA). So "P00303535" is likely the 303,535th c64 ever made (actually, there's evidence that the S serial numbers started with 1000, not zero) since most of the other facilities were just starting up production at that point. That serial number puts yours into early '83 as the date of manufacture, which also matches the late '82 and early '83 date codes on some of the chips.

Great video! Very insightful!

Great stuff. We had a Dragon 32 and somehow I never used the SKIP command, but I've just checked in the manual online and there it was.

Great video but too bad it came out after I had already went. This video would have helped me out alot if it had came out before October

That was my second computer!

Interesting! I never heard of the SKIP-command. It is only useful when you keep track of all the programmes stored on tape. I remember from the old day that the tape counter was used to find approximately the point where a programme was stored. But you need to make a list and write down the numbers of the tape counter. Simply nobody ever made a computer programme to do that, that was a lost opportunity.

I never enjoyed the cassette tape as a storage medium for files, due more to the sequential access than the speed. I was spoiled by the Apple IIs and their disk drives at school. That is quite the vintage Coco. It seems to be in perfect condition. It's nice that you're treating it with the respect it deserves. I had a Coco 3 in the '80s which I kept until 2001. At that time I was moving and I threw the Coco in the trash. It was a weird time for 8-bit micros-no longer of any real use, but not yet collectible. Most importantly, I was not trying to relive the glory days as I am today. I hope someone saved the Coco, but I doubt it.

I grew up in New Jersey, we had a similar store called Consumers Distributing. I bought many games for my Atari 2600 & C64 there. They eventually went out of business some time in the 1990s. I'm not sure if any catalog stores even still exist.

Good luck. The Coco was a fun computer to play with. The Coco 1 with standard BASIC was severely limited. It wasn't until they released the Coco II with Extended BASIC that they started to be more than a toy. I was a writer for a couple of small market Coco magazines back in their heyday. They were great fun to play with and to hack into. They were reasonably sophisticated thanks to the 6809 CPU, but electronically simple enough that someone with a bit of skill and knowledge could get into them and mod them up. Especially the Coco III if you abandoned TRS-DOS and upgraded to OS9. The last one I had I'd upgraded to 512K, dual drives, a decent keyboard, composite video and other goodies.

That SKIPF command is cool. I don't think we had that on BBC BASIC.
