Cases

A number of different style cases were used to house the Microbee as it evolved.

Microbee Kit
  • This case type was supplied only with the original Microbee kit.
  • It consists of 2 parts:
    • A folded black anodised aluminium base plate.
    • A black or beige coloured moulded Noryl (plastic) top cover. Early kits used the black cover and later kits used the beige.
  • The top cover is attached to the base plate with 4 self tapping screws, 1 in each corner.

All Standard models
  • This case replaced the original kit style and was offered as a upgrade option for owners of the earlier kit machine.
  • It is constructed of injection moulded plastic and has 3 parts:
    • Base, coloured off-white/light grey.
    • Keyboard surround, coloured black.
    • Top cover, same colour as the base.
  • The 3 parts are assembled using 6x M3 screws.
  • There are a series of separate peripheral ports at the rear of the case marked (from left to right as viewed from the rear) as:
    • Power - 1x or 2x round ports. The right port provides access to a 5 pin DIN socket carrying power, video output and cassette interface signals. The left port, if present, is unused.
    • User Port - not used by any standard Microbee.
    • Expansion Interface - either a 50 way expansion bus or 34 way floppy drive port, depending on model.
    • Serial Port - a 25 way D socket providing an RS232-like serial port.
    • I/O Port - a 15 way D socket providing an 8 bit parallel port.
Premium

All Premium models, including Premium Plus.
  • This case is very similar to the Standard case with these variations:
    • The keyboard surround has a larger cutout to accommodate the 4 additional Premium arrow keys.
    • The top cover incorporates a hole underneath the badge to allow ventilation airflow.
    • Individual peripheral ports at the rear have been merged into a single wide slot.
  • The top cover has the same peripheral name markings as the Standard case, but has only 3 holes in total:
    • Power - 2x round ports. These are unchanged from the 2x DIN port Standard case.
    • A single slot providing access to sockets for the Expansion Interface, Serial port, Parallel port and CGA video output.

256TC Case Bottom View


TeleTerm & 256TC
  • This case was originally developed for the Microbee "Delta" project which never proceeded to production. It was subsequently repurposed to house the TeleTerm and 256TC instead.
  • The case has 5 main parts:
    • Top cover - injection moulded plastic, coloured off-white/light grey.
    • Base - injection moulded plastic, coloured black.
    • Rear panel - folded aluminium, painted matt black on the external face with white port/control labels.
    • Internal disk drive/power supply mounting bracket - folded aluminium, unpainted.
    • Keyboard module - unpainted steel base, grey-green plastic top, grey-green and blue coloured keytops.
  • The main parts are assembled using 11x round head self tapping screws (3mm x 9mm). The rear panel is also attached to the 3x port sockets using 6x D port post screws.
  • Ports and controls available at the rear of the case are (from left to right as viewed from the rear):
    • Power - 1x round port providing access to a 5 pin DIN socket carrying power, video output and cassette interface signals.
    • Reset - a push button that resets the machine.
    • Colour - a 9 way D socket providing CGA video output.
    • Volume - internal speaker volume control.
    • Expansion slot - unmarked and normally unused, but can provide access to the internal 34 way floppy drive port for connecting an external drive.
    • Serial Port - a 25 way D socket providing an RS232-like serial port.
    • Parallel Port - a 15 way D socket providing an 8 bit parallel port.

 

Badges

The Standard and Premium cases feature a prominent branding badge at the rear of the top cover. The badge design evolved over time and does not appear to be a directly linked to changes in Microbee series or models, though there is some correspondence. Adding to the mix, customers were able to purchase a separate case upgrade at any time and most likely the current badge design would have been supplied with that new case regardless of whether that was a normal match for the customer's particular machine. The information presented here is based on a study of Microbee Online journals and brochures and should be considered as a guide only.

Microbee Viatel Labels
DEL and BREAK keytops and keyboard fascia.
Standard Models with Viatel upgrade option fitted. Premium models have only the keytop labels fitted (see Notes).
  • The Viatel upgrade option for Standard models was supplied with 3 labels. The first 2 labels are attached to the top of the DEL and BREAK keys to mark Viatel specific functions. The third "VIATEL" label is attached to the keyboard fascia right side - behind the Backspace key.
  • Later Premium models have Videotex (ex-Viatel) functionality included as standard. These models only have the 2 keytop labels fitted.
  • The keytop labels had a hard and limited life so may no longer be in place on machines today.
