MITS Altair firmware on 1702A EPROM!
See the "Altair Firmware" section near the bottom of this list.
 
Altair computers were manufactured in Albuquerque by MITS, Inc., which was later acquired and dissolved by Pertec Computer Corporation (Pertec did the same thing to another of their acquisitions, Icom Microperipherals.  Remember Icom’s "Frugal Floppy"?).  Altairs have become valuable acquisitions among collectors of technical and data processing equipment because of their status as being the first to introduce affordable computing to the general public.  MITS produced them years before Apple and IBM PCs existed.  In conjunction with the Altair, MITS introduced the first personal computer magazine (“Computer Notes”), the first personal computing accounting software, and the first personal computer conventions (the World Altair Computer Convention).  Of course, Microsoft got their start at MITS, too, writing the first high-level language (BASIC) for the Altair.  Before the Altair, another MITS first was the manufacture and kitting of many models of electronic calculators.  They also manufactured many types of electronic test equipment and hobbyist products.
All of those devices have their greatest value if they are operable, and that's why I am making copies of technical manuals available.  Although the great majority of these manuals are for MITS components, I also have manuals from several other companies whose 1970s products worked with, or competed with, MITS products.  Most of my manuals include theory of operation, operating instructions, parts lists, and assembly sections. In all cases, I will supply copies of everything I have available.  Sections concerning kit assembly may be missing from a few, and additional “in-house” information may be included with some.   Several pages may have annotations and other markings on them. This is because some of them were actual MITS technicians' working manuals and drawings.  I will always supply copies of the cleanest documents available, but you should not consider marked-up drawings to be inferior; usually the annotations will supply valuable technical information that would otherwise be difficult to find.  All are “technical” manuals, including schematics where applicable, unless otherwise noted as “operator’s” or “user’s” manuals only.
Please remember that these are copies of original manuals.  Be aware that, with very few exceptions, MITS originally supplied manuals that were loose-leaf photocopies of their in-house master documents.  There were very few offset-printed publications shipped.  Thus, there is usually little or no apparent difference between an "original" MITS document and my copies.  No matter what form the original is in, though, my copies are as close in appearance to them as possible.  (The page counts listed for the manuals are approximate).

TO ORDER:
Please contact me by email at
steveshepard@earthlink.net
           
Tell me the Product ID of the item(s) you want.  I'll answer back with total cost, shipping date, and any other necessary information. 

The prices listed include handling and First-Class postage within the US unless noted otherwise (prices are subject to change as postal and copy rates change). All manuals can usually be shipped within four business days after receipt of payment.  Payment from US residents may be made by  Money Order or Cashier's Check. 
VISA, Mastercard, Discover, and American Express payments may also be made via PayPal (click on the link at the bottom of this list to learn more about PayPal's free services).  Non-US customers please ask about payment options (many countries outside of the US can now use PayPal, too).  Please, no personal checks or COD shipments.
About my firmware and EPROMs
These are old stock (circa mid-1970s) chips.  Twenty-five year old code will often be partially erased by time, so I will  erase, re-program, and verify the chips when I receive your order.

l The prices include shipping by first-class mail in the US, packaged in anti-static materials.
l The prices do not include documentation, but it can be included for an additional $5.00, if ordered at the same time, and if I have it (see descriptions of currently available firmware documents above). 
l Supplies of 1702A EPROMs are limited, and my costs may vary wildly.  Prices and availability may change.
l I have much more MITS/Altair/Icom firmware that's not yet listed here.  Contact me about the chip you're looking for.
l I have the facilities to duplicate your existing 1702A firmware.  Confidentiality is assured.  Please contact me for details.
DISCLAIMER:  No guarantees are given as to the ability of any particular firmware to function with your computer's configuration.  The only guarantees given are that the code contained in the EPROM is the same as that which was contained in the original chips that were released by the original manufacturer (except for blank chips), and that the chip has been verified to be electrically functional..  You are responsible for furnishing any other software, firmware, or working hardware that may be necessary to make proper use of any chip(s) supplied by me.
If you have questions about what documentation you need for your MITS/Altair product, please ask.  I may be able to help you figure things out. 

If you are looking for a copy of a particular manual for an Altair era personal computer product that’s not listed here, please drop me a note.  I have lots of documentation that's still uncataloged, and I may have what you need. 

Do you have any MITS or Altair original manuals or documents that are not listed here, or that you think might be more complete than mine (see the “page count” columns)?  I would be interested in acquiring them, either by purchase or trade.  I am specifically seeking these manuals:

l  MITS laser transmitter manual
l  MITS Audio Sweep Generator manual
l  MITS "MITScope" digital LED oscilloscope (I'm looking for both the manual and the scope itself)
l  IMSAI 8080 complete operating and technical manual

In addition, I’m always in the market for MITS (or Micro Instrumentation & Telemetry Systems) hardware, and especially their calculators, test equipment, and other pre-Altair products.
Thank you for your order
