Machines We Ran, and Kept

We have been trading since 1989, and over that time a good deal of hardware has passed through our hands. Some of it we kept. We threw away far more than we saved, usually because at the time it was simply taking up space that a rack needed, and we have regretted most of those decisions since. What survived is listed below, and much of it still works.

This is not a reconstruction bought at auction. These are the machines we ran, the machines our clients ran, and the kit we used to connect them to each other before there was an internet to connect them to. Our history tells their story, and a fair amount of what it describes is sitting on shelves in Lincolnshire.

Kept, Sealed and Still Working

What is listed here is only part of it. The rest fills two large rooms, sealed in argon-filled vacuum bags to keep it exactly as it is, and every so often something comes out for attention. An AlphaMicro AM1200 and its AM102 terminal have just been on the bench, broken, and are now working again before going back into their bag. The HP LH4s are the exception: they are not bagged yet, because they are enormous.

Early Micros

IBM

  • IBM PC 5150 with two floppy drives, and its 5151 monitor
  • IBM PC/XT with a 10MB hard disk

The same model, with an eight port serial card, ran our first dial-up trial.

Nokia

  • Communicator 9000, which we wrote the initial software for
  • Its successor, which we ported the software to
  • 3310 and 6110

The Communicators carried GEN email and storage to the field in 1998.

Acorn

  • Acorn Electron
  • BBC Micro and BBC Master
  • Drives and monitors

Commodore

  • An early PET
  • Commodore 64 and VIC-20

Tandy

  • TRS-80 Models 1, 2, 3 and 4

Apple

  • Apple II and IIe
  • Mac Classic and SE

Research Machines

  • Several 380Z

Amstrad

  • PC1512 and PPC640

Psion

  • Series 5 and Series 7
  • Organiser II LZ64

Epson

  • HX portables and accessories

Servers and Minis

AlphaMicro

  • AM-100/L, the 68000 version of the AM-100, on the S-100 bus (S-Bus to everyone at the time), running AMOS
  • AM1200, a 68000 single board mini with a 20MB hard disk, and its AM102 terminal, both recently repaired
  • AlphaTerm terminal, in orange

AlphaMicro was where one of our founders worked before 1989.

Hewlett Packard

  • HP 9000, with drives
  • HP LH4, an early Intel server, and too big to bag

Racks of LH4s replaced our DEC AlphaServers.

DEC

  • AlphaServer 1000, early RISC
  • DEC Rainbow, now parts only

Our first web hosting platform ran on AlphaServers.

IBM

  • IBM 6150 running AIX, RISC

Part of the deliberately mixed estate we kept our options open with.

Systime

  • Systime 500, in parts: the chassis had to be left behind

Ferranti and Wyse

  • Ferranti Intel-based server
  • Wyse Intel-based server

Peripherals and Modems

Modems

  • Pace Nightingale
  • Hayes Accura and Optima
  • US Robotics Courier, and others
  • Motorola NT1D

Eight Pace Nightingales carried our first dial-up trial.

Hayes Century

  • Century R/RAS remote access racks

At its height we ran 80 of them, the largest Hayes Century operation in the world.

Control Data

  • CDC 500 Hawk drive
  • Around twenty Hawk cartridges

Disk Packs and Tape

  • A stack of multi-platter disk packs from a DEC system running TOPS, and from Allied Business Systems (ABS), an early and short-lived maker of minis and mainframes
  • A paper tape punch and reader, as a pair
  • Magnetic tape

Phoenix Peripherals

  • Phoenix 1500

And a great deal more

Hard drives, adapters, couplers and test gear, most of it in the argon bags.

Software, Manuals and Loans

GEN keeps a large archive of software, source code, manuals and documentation for legacy systems on the GEN WIKI. Only a small part of it is downloadable yet, because we have not had the time to curate it all, so if you are looking for something specific, ask and we will see if we have it.

If you are a museum wanting to borrow something for an exhibition, let us know and we will do our best to help. And we are always glad to hear from anyone restoring a machine of this vintage, whether you are after a manual, a disc image, a part, or simply confirmation of how something was meant to be wired.
