Commodore Amiga 500/500+ Keyboard Repair

A couple of weeks ago, I was testing out some upgrades on my 1995 Commodore Amiga 500+, when the keyboard died. It would sometimes work intermittently for a minute after power-on, but for the most part it was either partially or completely dead. The keyboard in the A500 and A500+ is its own separate embeddedContinue reading “Commodore Amiga 500/500+ Keyboard Repair”

1987 Commodore 1901 CRT Monitor Repair, Modification, & Restoration

I was recently given a 1980s Commodore 1901 CRT display by a friend, the third Commodore display for my collection (following a 1701 and 1084S-D2). It was in quite good condition physically, though it was missing its front control cover (a common problem with displays of this era) – it also came with a non-standardContinue reading “1987 Commodore 1901 CRT Monitor Repair, Modification, & Restoration”

IEC64W IEEE-488 Parallel Interface Adapters for the Commodore 64 & 128

I recently repaired and restored a 1983 Commodore 2031-LP 5.25″ floppy drive, which is unusual in that it uses the came IEEE-488 parallel interface as the earlier Commodore PET series of computers (GPIB connector), as opposed to the IEC serial interface used by the later Commodore 8-bit series of computers (DIN connector). This made testingContinue reading “IEC64W IEEE-488 Parallel Interface Adapters for the Commodore 64 & 128”

1983 Commodore 2031-LP 5.25″ FDD Repair & Restoration

I recently acquired my first Commodore 2031-LP 5.25″ FDD, another vintage disk drive to add to my collection, and a rather uncommon one at that. The drive was in reasonable condition, however it was bought untested and sold-as-seen with no accessories after being stored at the bottom of a wardrobe for several decades. The Commodore 2031 andContinue reading “1983 Commodore 2031-LP 5.25″ FDD Repair & Restoration”

Serial & Parallel Port Loopback Adaptors for the Commodore Amiga

I like to test all of the machines that I restore as thoroughly as possible, because thorough testing is necessary to verify correct operation – electronic devices are complex systems with lots of functionality and components, so just because something looks like it works (i.e. it boots), that doesn’t necessarily mean that it works properly.Continue reading “Serial & Parallel Port Loopback Adaptors for the Commodore Amiga”

Amiga A1010 3.5″ FDD Repair & Restoration

I recently acquired my first Commodore Amiga A1010 3.5″ FDD, another vintage disk drive to add to my collection. The drive was in reasonable condition and came with several accessories and its original box, however it was bought sold-as-seen. The Commodore Amiga 1010 3.5″ FDD was released in 1985 alongside the Amiga 1000, or A1000,Continue reading “Amiga A1010 3.5″ FDD Repair & Restoration”

Commodore 1540 5.25″ FDD Restoration

I recently acquired my first Commodore 1540 5.25″ FDD, another vintage disk drive to add to my collection. The drive was in reasonable condition and came with several accessories and its original box, however it was bought sold-as-seen and had several modifications and missing parts. The Commodore 1540 5.25″ FDD was released in 1981 forContinue reading “Commodore 1540 5.25″ FDD Restoration”

Commodore 64 (ASSY 250425) Board Repairs

Alongside purchasing complete systems, over the past few years I’ve also accumulated a large quantity of incomplete circuit boards for “spares and repairs”, primarily from Commodore computers (VIC-20, VIC-20CR, C64, C64C, C16, Plus/4, C128, etc). I got these for cheap in various job lots, with the intention of fixing up as many as possible andContinue reading “Commodore 64 (ASSY 250425) Board Repairs”
