SAPI-1
rdfs:comment
The SAPI-1 was a computer produced in the former Czechoslovakia by Tesla since 1980. It was designed by Eduard Smutný (hardware) and his brother Tomáš Smutný (software), and based on the Intel 8080/2 MHz clone (and later Z80). The was also developed as an 8086 clone of the PC. The SAPI-1 had a modular construction with modules: 3 versions of SAPI-1 were produced: * SAPI-1 ZPS 1 (základní průmyslová sestava - basic industrial set): integer Micro-Basic was stored in ROM, as well as simple machine code monitor, tape was used as main storage device, using single block recording. * SAPI-1 ZPS 2:

The SAPI-1 was a computer produced in the former Czechoslovakia by Tesla since 1980. It was designed by Eduard Smutný (hardware) and his brother Tomáš Smutný (software), and based on the Intel 8080/2 MHz clone (and later Z80). The was also developed as an 8086 clone of the PC. The SAPI-1 had a modular construction with modules: * JPR-1 - processor board based on MHB 8080 processor, 1 KB SRAM, 4 KB ROM modules and 6 IO ports * JPR-1Z - processor board based on Z80 processor * ARB-1 - bus unit * JZS-1 - power supply with rack * ANK-1 - non smart, no ergonomic membrane keyboard (comparable with Sinclair ZX-80 and ZX-81) * REM-1 - extension board with EPROM and SRAM modules * AND-1 - alfanumeric video adapter, 40 columns x 24 rows, black and white with 2 KBytes of video buffer at 3800 * AND-1A - alfanumeric video adapter, 40 columns x 24 rows, black and white with 2 KBytes of video buffer at E800 * RAM-1 - board of 32 KB of dynamic RAM * DSM-1 - modem and serial interface (based on MHB 1012 UART) used to communication with tape recorder * BDK-1 - universal developer board * DPP-1 - parallel port board (based on two MHB 8255 chips) * DGD-1 - B/W graphic video adapter - requires second monitor, cannot output to monitor connected to AND-1 * RPD-1 - floppy disk controller, due to its complexity (discrete glue logic) was built on two boards connected by cable. This came very late. 3 versions of SAPI-1 were produced: * SAPI-1 ZPS 1 (základní průmyslová sestava - basic industrial set): integer Micro-Basic was stored in ROM, as well as simple machine code monitor, tape was used as main storage device, using single block recording. * SAPI-1 ZPS 2: MIKOS (mikro kazetový operační systém - micro cassette operating system) with better machine code monitor was stored in ROM, any other programming language was loaded from tape, using blocks of 255 data bytes. * SAPI-1 ZPS 3: ROM contains CP/M booting sequence, CP/M is booting from 8" Shugart floppy disk drives. Position of VideoRAM was moved from 3800 to E800 to allow CP/M running.The "Z" version of SAPI-1 ZPS 3 used Z80 processor clone instead of 8080 clone, video with 64 characters per line instead of 40.
