This means also a very small number of chips and a compact board too.Įvery logic devices are fully reprogrammable on board enabling changes to original design in real time. Chrome project was developed starting from Speccybob design (Thanks Mike) but while speccybob was made only with TTL chips, Chrome features 2 CPLD from Xilinx that emulates not only 48K spectrum but a more powerful 128K, 7 MHz Z80 clock and floppy disk interface.
