You do not have permission to edit this page, for the following reasons:

This IP address has been blocked from editing Wikipedia.
This does not affect your ability to read Wikipedia pages.
Most people who see this message have done nothing wrong. Some kinds of blocks restrict editing from specific service providers or telecom companies in response to recent abuse or vandalism, and can sometimes affect other users who are unrelated to that abuse. Review the information below for assistance if you do not believe that you have done anything wrong.

The IP address or range 54.163.0.0/16 has been blocked (disabled) by ‪Blablubbs‬ for the following reason(s):

The IP address that you are currently using has been blocked because it is believed to be a web host provider or colocation provider. To prevent abuse, web hosts and colocation providers may be blocked from editing Wikipedia.
You will not be able to edit Wikipedia using a web host or colocation provider because it hides your IP address, much like a proxy or VPN.
We recommend that you attempt to use another connection to edit. For example, if you use a proxy or VPN to connect to the internet, turn it off when editing Wikipedia. If you edit using a mobile connection, try using a Wi-Fi connection, and vice versa. If you are using a corporate internet connection, switch to a different Wi-Fi network. If you have a Wikipedia account, please log in.
If you do not have any other way to edit Wikipedia, you will need to request an IP block exemption.

How to appeal if you are confident that your connection does not use a colocation provider's IP address:
If you are confident that you are not using a web host, you may appeal this block by adding the following text on your talk page: ((unblock|reason=Caught by a colocation web host block but this host or IP is not a web host. My IP address is _______. Place any further information here. ~~~~)). You must fill in the blank with your IP address for this block to be investigated. Your IP address can be determined here. Alternatively, if you wish to keep your IP address private you can use the unblock ticket request system. There are several reasons you might be editing using the IP address of a web host or colocation provider (such as if you are using VPN software or a business network); please use this method of appeal only if you think your IP address is in fact not a web host or colocation provider.

Administrators: The IP block exemption user right should only be applied to allow users to edit using web host in exceptional circumstances, and requests should usually be directed to the functionaries team via email. If you intend to give the IPBE user right, a CheckUser needs to take a look at the account. This can be requested most easily at SPI Quick Checkuser Requests. Unblocking an IP or IP range with this template is highly discouraged without at least contacting the blocking administrator.

This block will expire on 17:28, 10 March 2024.

Even when blocked, you will usually still be able to edit your user talk page, as well as email administrators and other editors.

For information on how to proceed, please read the FAQ for blocked users and the guideline on block appeals. The guide to appealing blocks may also be helpful.

))'''Sun-1''' was the first generation of [[UNIX]] [[computer workstation]]s and [[Server (computing)|server]]s produced by [[Sun Microsystems]], launched in May 1982. These were based on a CPU board designed by [[Andy Bechtolsheim]] while he was a graduate student at [[Stanford University]] and funded by [[DARPA]]. The Sun-1 systems ran [[SunOS]] 0.9, a port of [[UniSoft]]'s UniPlus V7 port of [[Seventh Edition Unix|Seventh Edition UNIX]] to the [[Motorola 68000]] [[microprocessor]], with no [[window system]]. Affixed to the case of early Sun-1 workstations and servers is a red [[Relief#Low_relief_or_bas-relief|bas relief]] emblem with the word ''SUN'' spelled using only symbols shaped like the letter ''U''. This is the original Sun logo, rather than the more familiar purple diamond shape used later.

The first Sun-1 workstation was sold to [[Solo Systems]] in May 1982.<ref>((cite web |first=Amar |last=Bhide |url=http://harvardbusinessonline.hbsp.harvard.edu/b02/en/common/item_detail.jhtml?id=390049 |title=Vinod Khosla and Sun Microsystems |publisher=[[Harvard Business School]] |date=14 December 1989 |archive-url=https://archive.today/20120709025144/http://harvardbusinessonline.hbsp.harvard.edu/b02/en/common/item_detail.jhtml?id=390049 |archive-date=9 July 2012 |url-status=dead))</ref>  The Sun-1/100 was used in the original [[Lucasfilm]] [[EditDroid]] [[non-linear editing system]].

[[Image:Sun100U Cardcage.jpg|thumb|Sun 100U Cardcage]]
The Sun-1 workstation was based on the [[Stanford University]] [[SUN workstation]] designed by [[Andy Bechtolsheim]] (advised by [[Vaughan Pratt]] and [[Forest Baskett]]), a graduate student and co-founder of Sun Microsystems.  At the heart of this design were the [[Multibus]] CPU, memory, and video display cards.  The cards used in the Sun-1 workstation were a second-generation design with a private memory bus allowing memory to be expanded to 2 MB without performance degradation.

The Sun 68000 board introduced in 1982 was a powerful [[single-board computer]].  It combined a 10&nbsp;MHz [[Motorola 68000]] [[microprocessor]], a Sun-designed [[memory management unit]] (MMU), 256 KB of [[zero wait state]] memory with parity, up to 32 KB of [[EPROM]] memory, two serial ports, a 16-bit parallel port and an [[Multibus|Intel Multibus]] (IEEE 796 bus) interface in a single ((convert|12|in|mm|adj=mid|-wide)), ((convert|6.75|in|mm|adj=mid|-deep)) Multibus form factor.

By using the Motorola 68000 processor tightly coupled with the Sun-1 MMU, the Sun 68000 CPU board was able to support a multi-tasking operating system such as UNIX. It included an advanced Sun-designed multi-process two-level MMU with facilities for memory protection, code sharing and demand paging of memory. The Sun-1 MMU was necessary because the [[Motorola 68451]] MMU did not always work correctly with the 68000 and could not always restore the processor state after a page fault.

The CPU board included 256 KB of memory which could be replaced or augmented with two additional memory cards for a total of 2 MB.  Although the memory cards used the Multibus form factor, they only used the Multibus interface for power; all memory access was via the smaller private ''P2'' bus.  This was a synchronous private memory bus that allowed for simultaneous memory input/output transfers.  It also allowed for full performance [[zero wait state]] operation of the memory.  When installing the first 1 MB expansion board, either the 256 Kb of memory on the CPU board or the first 256 KB on the expansion board had to be disabled.<ref>((cite book |title=Sun 1M Memory Board User's Manual |publisher=Sun Microsystems |date=February 1983 |id=Revision A ))</ref>

On-board I/O included a dual serial port [[UART]] and a 16-bit parallel port.  The serial ports were implemented with an Intel 8274 UART and later with a NEC D7201C UART.  Serial port A was wired as a [[data communications equipment]] (DCE) port and had full modem control.  It was also the console port if no graphical display was installed in the system.  Serial port B was wired as a [[data terminal equipment]] (DTE) port and had no modem control.  Both serial ports could also be used as terminal ports allowing three people to use one workstation, although two did not have graphical displays.  The 16-bit parallel port was a special-purpose port for connecting 8-bit parallel port keyboard and 8-bit parallel port optical mouse for workstations with graphical displays.  The parallel port was never used as a general purpose [[parallel printer port]].

The CPU board included a fully compatible Multibus (IEEE 796 bus).  It was an asynchronous bus that accommodated devices with various transfer rates while maintaining maximum throughput.  It had 20 address lines so it could address up to 1 MB of Multibus memory and 1&nbsp;MB of I/O locations although most I/O devices only decoded the first 64 KB of address space.  The Sun CPU board fully supported multi-master functionality that allowed it to share the Multibus with other DMA devices.<ref>((cite book |title=Sun 68000 Board User's Manual |publisher=[[Sun Microsystems]] |date=February 1983 |id=Revision B |url=http://sun1.sunhelp.org/198302_sun_68000_board_users_manual_revb.pdf))</ref>

The keyboard was a Micro Switch 103SD30-2, or a KeyTronic P2441 for the German market. The memory-mapped, bit-mapped [[frame buffer]] (graphics) board had a resolution of ((resx|1024|1024)) [[pixel]]s, but only ((resx|1024|800)) was displayed on the monitor. The graphics board included hardware to accelerate raster operations. A [[Ball Corporation|Ball]] model HD17H 17-inch video display monitor was used. An [[Ethernet]] board was available, originally implementing the 3 Mbit/s [[Xerox]] [[PARC (company)|PARC]] Ethernet specification, which was later upgraded to the [[3Com]] 10 Mbit/s version. An Interphase [[Storage Module Device|SMD]] 2180 disk controller could be installed to connect up to four [[Fujitsu]] 84 MB M2313K or [[Control Data Corporation|CDC]] 16.7 MB (8.35 MB fixed, 8.35 MB removable) 9455 Lark drives. All of the boards were installed in a 6- or 7-slot [[Multibus]] card cage.

Later documentation shows that a 13- or 19-inch color display was available. The color frame buffer had a resolution of ((resx|640|512)) [[pixel]]s, with ((resx|640|480)) displayed on the monitor. The board could display [[256 colors]] from a palette of 16 million. ½-inch [[9-track tape|9-track]] reel-to-reel tape drives and [[Quarter-inch cartridge|QIC]]-02 ¼-inch cartridge tape drives were also added to the offering.

There was also a second generation Sun-1 CPU board referred to as the Sun-1.5 CPU board.<ref>((cite book |title=Sun 120/170 Installation Manual |publisher=[[Sun Microsystems]] |date=March 12, 1984 |id=Revision C))</ref><ref>((cite newsgroup |title=Subject: Re: Performance of VAX/780/750, Pyramid & Sun |author=Mark Callow |date=August 8, 1984 |newsgroup=net.works |message-id= |url=https://groups.google.com/g/net.works/c/w1KEOk4wrxM/m/0imuUB56T2QJ |access-date=July 13, 2023 |quote=You might have a Sun-1.5 running 4.1c (which Sun have referred to as the Berkeley Beta Release of 4.2).))</ref><ref>((cite newsgroup |title=Subject: Re: Performance of VAX/780/750, Pyramid & Sun |author=Tim Mann |date=August 14, 1984 |newsgroup=net.works |message-id= |url=https://groups.google.com/g/net.works/c/w1KEOk4wrxM/m/euqQCudbSoYJ |access-date=July 13, 2023 |quote=there were some "Sun-1.5" processors shipped which ran 4.1c Unix.))</ref><ref>((cite web |url=https://github.com/ambiamber/4.1c.1-sccs2git |title=Explore 4.1c.1 BSD Source Code using Git |last=Mason |first=Amberelle |date=June 20, 2023 |website=GitHub |access-date=July 18, 2023 |quote=Sun hardware support was temporarily added to 4.1BSD and later removed before 4.2BSD was released.))</ref>

Sun-1 systems upgraded with [[Sun-2]] Multibus CPU boards were identified with a ''U'' suffix to their model number.
