| BASICare Modular Expansion System | This modular system was designed to expand a ZX81, TS 1000 or TS 1500 computer into machine capable of handling advanced applications. The cornerstone is the PERSONA, a module that is the interface between the computer and the other modules. With the PERSONA and other modules, the TS 1000 could be expanded to one megabyte | Timex/Sinclair 1000 |
| DROM | DROM stands for Development Read Only Memory. This module can have up to 8K of RAM, via plug-on 2K RAM chips. The memory is backed by rechargeable battery for non-volatile storage of programs and data. Behaves as normal read/write RAM when the computer is in use. Individual 2K blocks can be protected against overwriting. DROM | Timex/Sinclair 1000 |
| LINK a | A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
| Minimap | Memory mapping device to expand address space from 64K bytes to 1 megabyte. Organized into vertical 64K pages. Up to 16 pages can be supported. All memory can be dynamically defined from within a program, allowing (for example) a program in one segment to manipulate the contents of various data segments. A module in the | Timex/Sinclair 1000 |
| PERICONa | General purpose, user-programmable 24 lines of input/output. Up to 4 PERICONa can be used together. Up to four can be used simultaneously allowing basic I/O, strobed I/O, and bidirectional 8 bit data transfer with handshakes. A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
| PERICONb | 24 lines of heavy duty output to access and control the outside world. Lines are capable of operating relays or driving long signal lines. Up to 4 can be used. A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
| PERICONc | Centronics printer interface. A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
| Persona | The PERSONA is the base module of the BASICare Modular Expansion System, interfacing to other modules. It buffers all the signals from the expansion port via a ribbon cable. It connects to other modules via a 64-way Organic Bus, configured to fit into the ZX81/TS1000 memory map. Gladstone Electronics planned to introduce a PERSONA module | Timex/Sinclair 1000 |
| RAM 08 | Low cost memory expandable from 2K to 8K. Located in an address space not used by BASIC. Ideal for data or machine coded routine shared by second program. A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
| RAM 16 | 16K memory module. On-board address decoding permits simultaneous use of many RAM 16 modules in conjunction with Minimap. A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
| RAM 64 | Arranged in 4 blocks of 16K; all can be used under MINIMAP control. On board address decoding allows simultaneous use of many modules with MINIMAP. A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
| SONUS | Three-voice, AY-3-8910 sound-chip based module with stereo option. A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
| Toolkit | Uses up to four 2K EPROMs. Address space after on-board ROM. Allows calling TOOLKIT-held routines with USR function. Several TOOLKIT modules can be used under MINIMAP. A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
| Userfont | User defined characters for use with DROM or RAM 08. Define a set of 128 characters. Characters can be stored in EPROM by using TOOLKIT. A module in the BASICare Modular Expansion System. | Timex/Sinclair 1000 |
