The original Commodore 64 had a pretty long run for a computing platform, released in 1982 and discontinued in 1994. Its fortunes mirrored that of the company which developed it as Commodore achieved its greatest success with the C64 and never quite managed to achieve a similar level of market...
A very happy holiday season and Merry Christmas to those of you who celebrate it (timezone may vary). Also, I don't think I nearly say thanks enough to my regular patrons through Ko-fi, and I want to also thank them on behalf of the geriatric systems their generosity — and all of you who have...
Way back (well, six months ago, anyway), when I was wiring up a Gremlin Blasto arcade board, we talked at length about this 1978 arcade game's history and its sole official home computer port by Milton Bradley to the Texas Instruments 99/4A. In the single player mode you run around in a maze and...
Pretty sure this will end up as one of my longest-term restoration projects, but I'm back in the Southern Hemisphere for a little while to visit my wife's side of the family and giving me another opportunity to see if we can make progress on our defective PAL 128DCR, my favourite Commodore...
To those people familiar with the MS-DOS command prompt, have you ever wondered how similar tasks are accomplished with non-PC compatible systems? Well, I am one of those people and I have wondered, so I have written this blog article to compare common disk operations with the DOS for the IBM PC,...
In the calendar year of 1986 Tandy introduced two all-in-one computers, the Tandy 1000 EX and the Tandy Color Computer 3. Both were competitively priced at $799.00 and $219.95, respectively. At first the budget-conscious consumer may have chosen the CoCo 3 over the EX. By the next year the price...
The 1977 Trinity, Courtesy of Wikipedia, Image by Timothy ColegroveConsider that you have been transported back in time to the heady and hot summer of 1977. You are wanting one of these new "personal computers" that you see advertised in Popular Mechanics and Byte Magazine. Maybe you've seen an ad...
Recently a friend of the museum sent us his breadbin Commodore 64 that he acquired online with complains that there is garbage on the screen and there is no cursor. As much as we like restoring vintage computers and dealing with newer problems that enrich our knowledge base, we have never actually...
I bought a "dead" 1551 drive a few months ago. It's a european model, only 220v, and they said "it smoked when it was on". Well, i figured it was dead but I figured maybe not dead dead.So, step one was removing the .. huge ass transformer.I stripped off the regulators and hooked it up to a pair of...
So as we left it, we should have something like you see in fig. 1, the mains side of the PSU is wired up with the fuse and the optional lamp.On to the tricky bit!I was lucky, and had an existing DIN connector from an old non-functional c64 power supply that came with the c64 I bought from eBay,...
PSU in action - you too can build this!After watching the amazing Jan Beta build a c64 PSU from bits, effectively cobbling a 5v PSU and a 9v transformer together, I thought I'd give it a go myself.The c64 is that iconic 8bit computer we all loved back in the eighties. It has a very odd PSU which...
