The Nintendo NAS contains the following hardware.
CV860A Motherboard with onboard Via Eden C3 at 800Mhz
512 Mb RAM
400Gb 3.5″ IDE Hard disk.
3 * 100MB Lan connections
The LEDs on the front panel indicate power, disk activity and LAN activity. The power button turns the NAS on (funny that!) The reset button is not connected.
I’ve not put a CDROM drive inside the unit that utilises the cartridge flap on the front. Ive mounted the hard drive behind it instead.
The plan was to install FreeNAS, but I’ve now decided to put Ubuntu server on instead. I can then put a full Apache/MySQL installation on it and publish its website to the internet. I will put a guest book system on it, so visitors can sigh the log. Keep an eye on nintendonas.retrocomputers.eu . I should have the site live by the new year.

Netronics ASCii Keyboard with "FastVid" board in its original heavy gauge metal "Big Blue" case. Supplied as a self-assembly kit for use with the Netronics ELFII (RCA COSMAC 1802) and Netronics Explorer kits c1978. Modded by addition of power & shiftlock LED indicators. I really must replace those clumsy brass bolts with something more discrete.
My new baby. Arrived today with a lot of cool games: Atic Atac, Spy vs Spy, Dizzy, Jet Set Willy. And with a wonderful Bug-Joystick!
Humor me with these, the BBC Micro & Master were my first experience with computers, I learnt BASIC on a Master at Primary School.

Initial startup. Yay... it works. The wayward pink and white wires will eventually connect TP1-1 and TP2-1 from the ELF2K mainboard to the hex keypad. The CF/RTC/UART daughter board is yet to be installed. The 4 digit address and 2 digit data hexadecimal displays are legacy TIL311s.
There is a reason why I re-sprayed this VIC-20. It was soooooo yellow. No retr0bright solution was available at the time.
When I was spraying the machine, I ran out of paint. You can still see some of the original colour around the edges. Im going to get another can of paint soon and finish the job. Need to get rid of a couple of finger prints too! :)

Its my dads 60th birthday later this week. He is a bit of a Apple fan, so my wife made him a iCake 6.0. Not only does it look great, it tastes great too.

This is a modified CPC Plus cartridge. I have removed the EPROM that was soldered onto the PCB and replaced it with a IC socket. I can now burn my own games onto a 27C1001 EPROM.
There is a blog post about it here wp.me/p11CVu-wq

EasyFlash is a cartridge for the C64 expansion port. In contrast to traditional cartridges, this one can be programmed directly from the C64.

The Apple Macintosh IIci was an improvement on the Macintosh IIcx. Sharing the same compact case design with three expansion slots, the IIci improved upon the IIcx's 16 MHz Motorola 68030 CPU and 68882 FPU, replacing them with 25 MHz versions of these chips.

AMD produced what is probably the first floating point "coprocessor" for microprocessors, the AMD 9511 "arithmetic circuit" (1979), which performed 32 bit (23 + 7 bit floating point) RPN-style operations (4 element stack) under CPU control.
________________________________________________________________
AM9511 APU (arithmetic processing unit) performs floating point calculations that would be too time-consuming or cumbersome if done on Z80 microprocessor.
In addition to the four basic operations, the 9511 can implement transcendental functions (sin, log, etc.), and it can also perform conversion from floating point to fixed point and vice versa. It can also perform operations in 16 or 32 bit fixed point two's complement integer representation.
The fastest instruction is 16 bit fixed point addition which takes 4 microsec, the slowest instruction is arc-tangent which takes almost 2 milisec; 32 bit floating point addition takes 14-87 microsec.
The 9511 is an autonomous processor: it acts like a peripheral and it in not tied to any particular microcrocessor. AM9511 is configured as a pair of I/O ports with the capability of causing the Z80 to pause for completion of the processor's operation if it has not been completed by the time the Z80 code requires the results.
The 9511 is a stack orientaded processor. Operands are first pushed onto the internal stack, and then a comand is issued to the processor to perform an operation on the stack. Results are removed from the stack.
All transfers, including operands, results, status and command information, take place over an 8-bit bidirectional data bus. The internal data paths and the internal ALU are 16 bits wide, even though some operations are on 32 bits operands (this fact indicates that extending the 9511 to handle double precision format could have been implemented internally quite easily). The transcendental functions are evaluated using Chebyshev Polynomials which provide an even distribution of errors within the selected data representation.
The 9511 was in 1980's an high cost device: the APU was far more complex than the CPU and the volume of sales was not so high. As a result this was reflected in the price: in 1983 the Am9511@2Mhz cost £90 (considering inflation it would cost £240 now in 2009), the 3Mhz £123.75, the 4Mhz £146.25 ..

One of my hobbies is collecting retro-computers, focusing on computers made by Atari. I have currently have eleven different Atari-models, three from Commodore and one other model in my collection.
The Atari Stacy was Atari's first attempt at building an portable computer based on the Atari ST. It it the market in the end of 1989.
In 2011 I was looking to buy an Atari TT, inspired by a friend who just bought a Commodore SX64, a portable Commodore 64, which was kind of his dream computer. The TT was the computer I always dreamt about owning, so now I was searching Ebay and other places for one.
At the same time as I the TT I was going to buy on Ebay, there was an Atari Stacy for sale on Ebay as well, located in Stockholm. As this is a quite rare model as well, I thought it could be worth to try to win the action, and luckily I did.
My friend who bought the SX64 picked it up for me in Stockholm. The seller told him he was glad I won it, I was bidding against someone from South America, so the seller worried about how he would pack it and ship it.
This Stacy is pretty battered and well used, it has been used for what the Atari ST is best known for, it's MIDI-capabilities. The floppy drive was replaced and not working very well, and the 20MB hard drive was just making lots of noise. The ASCI-port and the internal SCSI-adapter seems broken as well, and the back light, which is known for it's limited life span, is barely working. Some keys on the keyboard isn't working due to a broken connection, but still it has one of the nicest keyboards I've ever used.
I've replaced the floppy and removed the hard disk (it had leaked some gooey fluid too all over the internals of the computer). I'm thinking of replacing the backlight with a modern LED backlight.

L'8 luglio 2015 è stato presentato ufficialmente a Highgate, Londra, la nuova console di videogiochi ZX Vega. Basato sull'architettura del Sinclair ZX Spectrum, il Vega è sviluppato e prodotto dalla Retro Computers Ltd (www.zxvega.co.uk), un'azienda fondata da Clive Sinclair, Chris Smith, David Levy e Paul Andrews ed è stato finanziato attraverso una campagna su Indiegogo che ha raccolto circa 150.000 sterline, il 50% in più del traguardo inizialmente fissato. Io sono stato invitato all'evento, unico italiano presente, in quanto nella dotazione iniziale di 1.000 giochi compare anche il mio Cousin Horace, uscito nell'ottobre 2014 (per saperne di più: www.alessandrogrussu.it/diario-2014-10-01.html).
Nella foto: il dott. David Levy legge un saluto ai presenti di sir Clive Sinclair, assente a causa di un incidente che lo ha colpito pochi giorni prima dell'evento. A sinistra, Chris Smith; a destra, Paul Andrews.

I was invited, the only one from Italy, because my Cousin Horace, released in October 2014, has been included in the initial set of 1,000 games coming with the console (more on this can be found at: www.alessandrogrussu.it/diario-2014-10-01.html).

APOLLO181 has been conceived and assembled in Italy in 2012 by Gianluca G. (author of the homemade Z80/AM95 microcomputer) using early 1970s TTL technology. Designed and tested with the aid of a hardware simulator, APOLLO181 is running today at 2.5 MHz on a 12x12 inches single perfboard.
APOLLO181 is a multi-chip board and its peculiarity is that all the employed TTL components were described in the Bugbook® I & II (LOGIC & MEMORY EXPERIMENTS USING TTL INTEGRATED CIRCUITS, written by Dr. Peter R. Rony © 1974, 1st edition), as a Gianluca G.'s personal tribute to these books. By happy coincidence we are also approaching the 40 years Bugbook® publication anniversary.
