IBM PC BASIC ROMs
|
|
---
|
|
|
|
The project contains the following IBM PC BASIC ROMs:
|
|
|
|
* [IBM BASIC C1.00](BASIC100.json)
|
|
* [IBM BASIC C1.10](../../5160/basic/BASIC110.json)
|
|
|
|
These built-in versions of BASIC were also referred to as Cassette BASIC, because no disk drive was required.
|
|
Only the original IBM PC (Model 5150) actually provided a cassette interface, but IBM continued to use that
|
|
name to describe the built-in BASIC, at least up through the IBM PC AT (Model 5170).
|
|
|
|
Both versions of Cassette BASIC where 32Kb and spanned physical addresses 0xF6000-0xFDFFF. They were produced by
|
|
Microsoft, and unlike the IBM PC BIOS ROMs, no source code listings of these BASIC ROMs were ever published.
|
|
|
|
Here's an [IBM PC Machine](/devices/pc/machine/) XML excerpt that shows how to include a BASIC ROM:
|
|
|
|
<rom id="romBASIC" addr="0xf6000" size="0x8000" file="/devices/pc/rom/5150/basic/BASIC100.json"/>
