I’ve decided to sell of a few PDP-8’s as the hoard is getting rather large at the moment and so I’m prepared to part with the following:

• PDP-8/M, 8KW core, M8650 serial UART, very clean machine in working order. This machine is currently listed on ebay here: http://www.ebay.co.uk/itm/ws/eBayISAPI.dll?ViewItem&item=320762438517&ssPageName=STRK:MESE:IT
• PDP-8/E, 4KW core, M8650 UART, requires a full rebuild
• PDP-8/A, 16KW core, extended memory, serial, paper tape drive and controller (non DEC). Very clean and in working order
• RX8E + RX01 drives
• PC8E + PC04 paper tape
• DECmate III
• WP78 (aka a VT78)

Email offers to toby@pdp11.co.uk . Machines are located in UK

A new arrival in my collection was a fairly clean PDP-8/E chassis. The box came with no cards but I have sufficient spares to populate.

First step in rebuilding it is to strip it down and remove all the foam gunk before moving onto reviving the power supply.

Here are some pictures from the strip down

Here are a collection of You Tube videos featuring PDP-8s playing music:

A rather nice new arrival for my collection is a PDP-8/E. The machine is in 3 H960 racks and has a pair of RK05 drives and a pair of Magtape drives (with pertec interfaces).  The 8/E has an expansion box giving a total of 40 slots. The machine has 12KWof memory, 3 x serial ports and a posibus interface. Alas there were no disk packs with the RK05s although I do have one 16 sector pack (unique to PDP-8s)

The machine was owned by a local company who had it in the basement of their country house and they were the owners from new. Removal required us to get the machine up a very steep and narrow staircase and so we had to dismantle the machine considerably in order to get it out. Careful notes and pictures were taken to aid in reassembly.

The machine is going to get pride of place in my office alongside my PDP-11/70 and PDP-8/Ms.
