I LOVE Micro Men! It's such an awesome film and tells the story of the early 80s UK computer industry really well. Plus it also has some funny moments in it, too.
There was a batch of micro PDP-8 kits that sold out last year. I think they were around $500 a kit.
Anyways, friends of Facepunch I have a challenge for you.
I picked up an Apple Lisa but there was one big problem with the unit.
Some asshole thought it was a good idea to paint the skin panels black.
Thankfully the guy who did it sucked ond there is only one thin layer but I don't know how to get it off. The stamping says it's "TP" (probably Thermoplastic but that's still a fucking vague name) so I can't just start throwing cleaning agents on them. Some agents like acetone will attack some plastics and ruin them. Others won't do anything. I had mild success when I coated one panel in DOT 3 brake fluid but that shit is expensive There is no way I could treat all the panels and even then I was still getting black paint stuck in the texture of the plastic.
What should I do?
Why the hell did they always have to show bar graphs on computer screens in ads for them in the 80's? Why not show something cooler.
According to a post on the forums, they're moving or something. Let me find it...
(Also, my new goal: Track down a TRS-80 Model 102)
EDIT: "We are moving all of the kit parts from one house to another. In a few months we will be able to sell kits again."
Gonna get a BBC Model B off eBay, I miss chuckie egg :D
The results of my paint stripping experiments were a total success.
I knew from a previous test that DOT 3 brake fluid worked best at softening the pain without doing anything to the plastic that I could see. The problem was that the brake fluid thinned out and I lost a lot of the stripping efficiency.
The experiment consisted as follows:
-A bottle of DOT 3 brake fluid
-Metal cookie tray (grab an old or a cheap one because you don't want to use it again after this)
-Cheap non-synthetic paintbrush
-Small Plastic container (a small peanut butter or jam jar will do)
Start off by placing the panel on the tray and start using the brush to cover the panel with brake fluid.
Once that's done, place a sheet of paper towel on top and soak it using the paintbrush and more brake fluid. The paper towel helps keep the panel soaked by preventing the brake fluid from easily flowing away and into the tray.
Leave the panel alone after this for a few hours.
I came back and checked on my piece after four hours and lifting up the paper towel showed that the black paint had wrinkled which meant that it had been stripped off the panel.
Now take off the paper towel and if you have more pieces, put it in the tray under the panel so it does not make a mess, otherwise put it in a bag and throw it out.
Now take the putty knife and start scraping the paint. You should not need much effort and the result will look like this:
The paint will have completely separated from the plastic leaving a skin of black sludge.
Continue scraping off the sludge and use the small jar to put the toxic scrapings into.
Once you have scraped off all you can (there will probably be a few places where you can't get the paint to come off) you can take the garden hose or something with a sprayer and blast off any residue.
You can see that for the most part it was a total success with the exceptions where I didn't properly coat or in the vent grilles. For the most part you can get the last of it off using a bit more brake fluid and a toothbrush but otherwise the plastic is fine.
I haven't tried it myself, but the photos on the site look promising.
It's hard to get Retr0Bright supplies here. There's a few key components the locals use to make meth.
I wonder what sort of heartless bastard would defile a lisa like that?
Also, i kind of want to get one of the TRS-80 pockets and take it with me on my next vacation like a bobblehead.
...alright, i admit it. that post about the TRS-80 Model I piqued my interest. I'd get everything i could afford if it weren't for my limited cash and space. Still, i have space for a Model 102 and at least a few of the different pocket models.
Can anyone help identify this old computer?
Haven't been able to find anything on this old beast myself.
Linking instead of image tagging, since they're huge and this computer is gimped so I (somehow) can't use MSpaint.
Half the reason for that is probably because it's missing it's proprietary keyboard and the OS floppy disk.
It's so old it doesn't have a harddisk.
http://www.grafityp.com/English/about.htm If you'll note, it says it's a Grafityp CSR, meaning Computerized Signmaking Robot, in your photos. Here on this about page for Grafityp it mentions the CSR, made in 1984. It seems like it was designed as a computer to operate a sign cutting machine for large signs/sign-making materials, and the about page mentions adhesive film a fair bit.
It's a clone PC/XT I believe that was made by Philips. It should take DOS 3.3 no problem.
I would however recommend opening it up, removing any unnecessary cards besides video and also pressing down on any socketed chips in case they have "creeped" out of their sockets a little.
Also gonna work on some more photos I took of it before I upload and post them.
Photodump of the old beast:
better picture of one of the logo's on the back.
Serial expansion card.
The GFX card for the special monitor it was sold with, it apparently doesn't work with the onboard port.
Notice the green wires on the card, seems like it's been modified.
manufacturing date for the motherboard.
20'th july 1984
half filled RAM bank (I guess)
DIP switch I suspect isn't set correctly
general inside picture
bottom picture, note the small plug and cable on the bottom.
That's apparently for the keyboard which i though was the wrong one at first.
general back shot.
Four ISA Slots means it's an 8088 PC clone. You're not going to find any onboard I/O on that thing. With the exception of the keyboard port the only way to add things such as serial/parallel, sound, disk drives, memory, and even a clock have to be done through the ISA slots.
If you open it up right now the very minimum you will find inside for cards will be the video card and a floppy controller. To add a hard drive you'll need an ST-225 and a compatible MFM controller. Unless you want to dig deep, you won't get IDE working on this.
After doing some research on my own, it seems like MIPS is right.
The computer is basically a tweaked clone of the IBM Personal Computer model 5150 if I'm not mistaken.
EVERYBODY made at least one PC/XT/AT Clone. China cranked out MILLIONS of cheap marginal quality boards which were generally okay to use (because the were straight copies of the original IBM boards) and all a company like Philips had to do was look for a case, drop in the board and bam, you had your OEM PC product.
Guess they did most of the work, and Philips just assembled it and slapped on their badge.
Or they at-least made the monitor and the special 8-bit ISA gfx card for Philips to use in this computer model..
Goddamn this thread interests the FUCK outta me
