More additions en extensions on the Mainboard
One of the things that need an improvement is to provide the printerport with an eighth bit. Read here about it.
The memory can be extended in several ways. -
By piggybacking ICs on the existing 2114 memory chips.
- By replacing the main- and / or the video-memory with CMos Ram chips.
- By the addition of a 16K memory-card, a 64K RAM-card and / or a bankswitching-card, on which EPROM's and Ram for the #A000 block.
Next. - Using a bankswitching-card, it is inevitable to modify your F-Rom.
- A sufficiently regulated powersupply is necessary. And be sure it is able to deliver enough power.
