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”

A few months ago bought my first ever vintage radio, a 1970s Ajax Commander S-74 “solid-state” AM/FM set, which is among the oldest items in my collection.

1974 Sinclair Scientific Calculator Repair & Restoration

I recently acquired a Sinclair Scientific calculator from 1974, alongside a large bundle of vintage computers – this was an unexpected (but very welcome) surprise and is in fact my first vintage calculator, though it is basically a pocket computer, so it is certainly in keeping with the rest of my collection.

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”

Microsoft Xbox (Original) Repair & Restoration

I recently picked up an original Xbox, boxed with accessories, and in good condition.

The Xbox wasContinue reading “Microsoft Xbox (Original) Repair & Restoration”
