What is Included with Tom Durston's Custom system?


Hardware supporting a 60K Altair 8800a configuration. An 88-PMC boards allows for additional firmware and provides a powerful PROM monitor.

Hardware supporting 64K Altair 8800b configuration. This dual drive system is the functional equivalent of a MITS 300/25 Business System

Supplemental Hardware for Ethernet/Internet and USB Console.
  • An RS-232 to USB adapter allow direct connection to a PC or laptop.
  • An Ethernet allows console operation over a network.
  • Remote CP/M capability allows remote operation over a LAN or the internet
  • Major MITS Software including DOS, Fortran, BASIC versions, Utilities and application software.

Provenance: The system is owned by the original owner, an Engineering Manager at the Altair factory MITS. The system was used to develop MITS products, including the 8800b. Some boards have markings identifying MITS Engineers and internal MITS use. The system was used to develop multiple Altair products.

Time Saving: This system is highly functional and can be assembled into a working system will little work. It would take a very long time to assemble a similar collection of working parts. Getting two working drives and a controller pair is very difficult.

Risk Reduction: Disk drives serviced and tested. System assembled and tested just prior to shipping. RAM tested and passed two memory tests.

Power: A full 64K of static RAM. Three serial ports. Software includes MITS and CP/M diskettes with Altair Accounting, DOS, BASIC, and Remote CP/M.

Services: Boards tested and repaired. Drives tested, repaired, and serviced.

Enhanced firmware and software including Remote CP/M and Altair Accounting Software (download). Powerful AltMon PROM monitor.
