A less messy way would be simply to bend out pins 18 and 21 slowly towards a more horizontal angle, enough to clear the socket when inserted, then
put some wires into pins 18 and 21 of the socket and solder to pins 21 and 18 of the eprom. The rest of the pins can go in as normal.

Looks like You have wired it up properly, all pins go to the exact same position except 18 and 21 which are crossed over. Any chance of a photo of Your adaptor? It's interesting that the character Rom is the same chip, 2332, as is used in the c64, except there the PLA is responsible for chip selecti...

See here http://sleepingelephant.com/ipw-web/bulletin/bb/viewtopic.php?f=11&t=7058, this topic was discussed very recently. Looks like You just leave pin 20 as is, then rewire 2332 A11 and CS2 to the respective A11 AND /OE on the Eprom, although that sounds exactly like what You have done. Check...

If You look at some of the other schematics there You will see 1.2mh and 1.5mh, or in other words 1200 and 1500uh (Henry's). Personally I would just short it out with a piece of wire, The drawback might be some extra noise getting through on the 9v AC. I had a look at RS components here and Futurlec...

You are correct, but that is AFTER more than 3.15 Amps has been pulled through the fuse. If You are lucky only the rectifier and/or regulator will be shorted. It's well worth taking a look though. The Motherboard pic you posted is a PAL unit, exactly the same as mine :) and has a 74ls74 chip next to...

Time to get out the soldering Iron, Multimeter, Vic-20 schematic, and get testing. A 4A fuse would suffice for testing purposes only, get a proper 3.15A part if You get it up and running. It may help to know where You are, also post a pic of the mainboard so we have a clue what revision You have. Cl...

Fantastic stuff Groovydrifter, always a good feeling resurrecting an old Computer. Try here for a MOS 6502 http://www.aliexpress.com/w/wholesale-mos-6502.html?site=glo&SearchText=mos+6502&SortType=price_asc&groupsort=1&initiative_id=SB_20141011005045&shipCountry=au&filterCat=...

Using non-MOS 6502's can give some strange effects in some games, and likely break others completely. Take a look at the thread about Doom video glitches. I bought 5 Rockwell R6502AP versions from Aliexpress, they work fine and are brand new condition, but I still got some slight video issues in Doo...

Obviously You have a NTSC Vic, so cannot help there. PAL Vic chips are actually quite plentiful from China, and NOT fakes. I purchased a batch of them, 6561-101's and they all tested AOK. http://www.aliexpress.com/wholesale?SearchText=6561-101&catId=0&initiative_id=SB_20141008232521 yxchip i...

Good video, always like watching old tech vids. Did You check the 9v AC as well? at the plug I mean, obviously it's there as You wouldn't get +5v DC without it. If all voltages on the pins are good then obviously the next step is to pull the Vic apart and get checking inside. Looking forward to a fu...

I'd first try reseating the VIC chip, next replace the electrolytic capacitor which is c16 in older Vic's and c11 on the newer boards. It's a 1uf 16v part. Also check that there are no dry joints on the video/audio socket on the main board. Hopefully You can solder and don't mind pulling apart Your ...

yes that will definitely work, same as my Vic-20 has currently installed.

According to the diagnostic info from Ray Carlsen's website, Your problem should be One of the VIA (6522) chips. UAB1 6522 VIA INTERFACE, KEYBOARD-SERIAL Startup screen normal, but no cursor. Keyboard doesn't work at all. Partial failure: some keys "stuck" or don't work... may be a whole r...

You are correct, the 65C02 doesn't do undocumented opcodes, there were also other changes. Doom was the only game I tried that gave problems, although there is still a lot of software I haven't tried. Interestingly whilst doing some research about this I found out that when the Apple2C was released ...

I have an Avermedia H727 capture card in my PC, it has Analog and Digital tv. Composite, s-video, component, and Hdmi inputs. I captured that through s-video from my Vic-20 with the Avermedia software which is absolute rubbish except capture functions produce a decent result. The Digital TV is so ba...
