Having collected everything I needed I set to work on building the tower based HD Electron, at the time I christened it 'Super Electron'. The BBC HD required connection via a 1MHz bus, I knew Pres had produced one at one time so onceĪgain I watched the adds. so I thought I'd have a go at fitting one to an Electron.
BATTLE CHESS ACORN HOW TO
It came with the circuit diagrams showing how to build the hard disk addonĪnd plenty spares. I eventually bought one with a 40 Mb hard disk and IBM PC 2nd processor. I started to look around for a BBC Master.
BATTLE CHESS ACORN UPGRADE
This required a User Port so it was off on the upgrade trail.I ordered the With the MRB installed the Electron was once again stable and working a treat.Īt this stage I wanted to have a go at the Slogger Stop Press (a conversion from the BBC AMX product). I spent some time trying to fix it but to no avail so the Slogger Master Ram Board was now on order. The E2P worked well for about a year then it would occasionally fail to start. Jafa Systems, I had most of the components so assembled it myself and if I remember correctly it took some time to get the timing right for the refresh rates of the dynamic RAM. I purchased this as a circuit board and diagram from the Jafa Systems E2P, the Electron 2nd Processor. Not content, I saved up and bought a Pres +6 so I could have more EPROM based programs at my finger tipsĪnd to free up a cartridge slot on the Plus 1 for what was going to be my next expansion.
Sinclair QL, which paid for the Electron and part of a Pres +1/+3, my first of what turned out to be one of many expansions. My first Electron was purchased from a small shop in Glasgow in October 1987 for £40.
