  IMSAI 8080 computer
The IMSAI was certainly the best-looking of the early micro-computers, and was sold as both a kit or already-assembled and tested.
Like all early S-100 based systems, the IMSAI is really just a large metal case with a power supply, and numerous slots to insert the expansion cards.
Some call the IMSAI the first clone of another computer system, in this case, of the MITS Altair 8800, a similar computer which was release just a few months earlier.

  The IMSAI 8800
The name IMSAI 8080 was displayed in the upper right-hand corner of the panel.
Once the Imsai cover was removed, you could see that the obvious and most impressive difference between the Altair and the Imsai was the power supply.
In fact, the Imsai 8080 became one of the less popular computers in the stores.

It was compatible with its main competitor, the earlier MITS Altair 8800, by which it was inspired.
Full scale development of the IMSAI 8080 was put into action, and by 1975 an ad was placed in Popular Electronics, receiving positive reactions.
By October 1979 the IMSAI corporation had gone bankrupt, and the 'IMSAI' trademark was sold to Fisher-Freitas Co, who continued manufacturing the computers under the IMSAI name; however these models are different than the originals produced by IMS and IMSAI Manufacturing Corporation.

 The IMSAI 8800
This allowed the Imsai to be made with the motherboard perpendicular to the front panel so that the front panel itself could be plugged into the first connector on the motherboard.
One very important thing that Imsai did to advance the use of floppy disks was to license the best disk operating system, later to be known as CP/M. In fact, it was money from the Imsai license that encouraged Gary Killdal to form Digital Research Incorporated and to get into the CP/M operating system business.
While Imsai never became a successful systems house as did Cromemco and others, the Imsai 8080 with its massive power supply and 22-slot chassis was a foundation for almost any 8080 or Z-80 system you could think of.

Molti si chiedono a cosa servissero: ebbene, il caricamento di un programma nella memoria dell' IMSAI 8080 avveniva spesso byte per byte, ovvero impostando manualmente i singoli byte di dati tramite gli interruttori.
Bisognava impostare sugli interruttori dell' IMSAI 8080 i singoli bytes che definivano un "loader", poi leggere con una macchina speciale il nastro perforato con il programma di compilazione.
Questo fu uno dei piccoli inconvenienti che caratterizzò la nascita dell' IMSAI 8080: presto si resero disponibili lettori di dischi da 8 pollici e schede aggiuntive, che facilitarono ogni operazione.

 The Official IMSAI Web Site
Actually, that article told of an early predecessor to the IMSAI 8080 that was developed prior to the announcement of the Altair, but tentatively based on a DEC bus instead of what became known as the S-100 bus, introduced by MITS in the Altair.
I replied to Ed that I have always rejected the notion that the IMSAI 8080 was the first "computer clone" since it doesn't resemble the Altair in any way other than choice of bus and cabinet color.
Happily, all seems to be reconciled, with the unexpected result that Ed Roberts and IMSAI 8080 creator Joe Killian have "virtually" met and communicated in a polite and respectful manner for the first time ever, a direct result of my having copied e-mail communications to each during resolution of the misunderstanding.

La IMSAI ebbe il merito di diffondere la cultura del computer tra gli appassionati: il primo prodotto, l' IMSAI 8080, fu il principale concorrente dell'Altair, il primo computer della storia venduto in kit.
Migliaia di appassionati trovavano nell' IMSAI il punto di incontro tra professionalità e flessibilità offerta da un sistema "aperto" a modifiche ed interventi manuali.
L' IMSAI VDP-80 arrivò nel museo una mattina di gennaio, ricoperto dal fango e reduce, forse, da una traversata atlantica.

The computer they designed, the IMSAI 8080, was very similar to the Altair 8800 and was designed to run the same software.
The IMSAI 8080 aimed to take advantage of the Altair's popularity, the inability of MITS to meet a growing demand for the product, and the need to improve on some of the internal components.
At the production starting, the IMSAI was shipped deliberately missing many parts in the kit version, because the company hadn't received them yet.
