In 1984 Sinclair launched the ZX Spectrum+. A fully suitable name, because the 'Plus' was nothing more then a face lifted normal ZX Spectrum, the big bang for Sinclair that was launched two years before.
The Spectrum+ tried to solve the biggest minus of all Sinclair computers so far: the awkward keyboard.

Retired objects
My computers seem to stay around forever. Here is my first color computer -- MacIntosh LC dating from about 1990, and my first PowerMac -- the 7100 from about 1994. Both have been retired for 25-30 years. I don't know why I hang on to them.
I didn't look at it carefully, but on top may be my first ever external hard disk. If it is, I paid roughly $1000 for 100 MB hard drive in 1990. At the time, that seemed like an enormous amount of storage compared to the 640 KB you could put on a floppy disk.
Since this photo was taken deep in our dark and dirty basement, I was inspired to finally dig out my speed light to provide lighting. Until today, every other photo that needed lighting was done with the ring light I bought when we were doing on-line instruction during last year's COVID lockdown.

I've always been fond of the IIe - the first one I saw was at Myers back when they had a dedicated business computing department (although technically it was the Platinum model), and I really impressed - it seemed so much fancier that the VIC-20s and Commodore 64s I was used to.

My first computer (1980) with 64K of memory! Using a Motorola 6809 processor it had Multitasking / Multiprocessing - Up to 4 users at once could work on it. Not seen is my Epson MX-80 dot matrix printer $400.
Some years back I met someone with a pile of IIc's in his shed, which he passed on for me to look after. I still hope to do something in order to display them properly one day. Interestingly, one of them had the LCD display shown here - they're quite unusual, as they were truly awful at the time, so comparatively few were sold.
I'm very fond of the IIc - it see it as one of the three computers which seem to best exemplify Steve Job's particular vision, for good or ill.
Here is the Powerbook Duo 230, which was the only one of the three that we were able to power on to a working operating system.
The Oric Handbook by Peter Lupton and Frazer Robinson. Published by Century Communications in 1983, this is one of those books that aims to provide an alternative to the official manual.
this is one of a series of portraits I was hired to to for a software company. All of the portraits are of employees that have been chosen to represent the company in an ad campaign that will appear in the Behavioral Healthcare Magazine. I was hired to do the portraits and design and write the copy.

The Osborne Vixen was conceived as the replacement for the popular Osborne 01 portable computer, which was released three years earlier in 1981.
Originally, the Vixen consisted of a light-weight black plastic case, with two horizontally-mounted 400K floppy drives, and a 5-inch green CRT. The keyboard is permanently attached, and folds down to act as a stand to support and raise the front of the system.
A vast improvement over the Osborne 01, the Vixen 4 is smaller, lighter, and has higher-capacity floppy drives.
The small 5-inch (diagonal) CRT screen displays 24 lines of 80 characters each. Fortunately, it is very sharp and crisp, as the tiny 1mm-wide characters would be unreadable on a lesser monitor.
Unfortunately, in September of 1983, the Osborne Computer Company (OCC) ran into financial difficulties, declared bankruptcy, and the Vixen in its original incarnation was never publicly released.
It's not certain how a few of these never-released Vixens escaped into the wild.
As luck would have it, the Osborne Computer Company survived bankruptcy and in 1985 returned to viability, to officially release the Vixen into the public. This re-designed system has the drives mounted vertically to allow the use of a larger, 7-inch amber display. Other changes include an off-white case instead of black
