The 68SEC000 is the same price and MUCH faster and cooler. Also, two more address lines than the PLCC version and four more than the DIP-48.lezanderson wrote:68008 CPU (HD/MC68008P12) 12Mhz Max.
I wish Sinclair used the DIP-52 version of the 68008 back then, before the PLCC one was available.

Oh, make it easy why don't you? If you can do VHDL I can get you the documentation you need - mostly, it's all here and provided with explanations by the very talented Mr. Nasta.lezanderson wrote:CPLD to emulate ZX8301,ZX8302
Microdrives are handled by the 8302. The 8049 does keyboard scanning, sound generation and the receive side of serial.lezanderson wrote:Modern MCU to do functions of 8049 including Handling Microdrives

If you replace the MC1488/1489 with a single voltage serial transceiver, you don't even need +/= 12V.lezanderson wrote:Voltage Regulator to supply +12V, +5V to Board.
Yes, we've all had these thoughts 1000 times.
