ZX-Spectrum MB02+IDE - last mod 22.10.2007
News:
22.10.2007 ... solved a problem with the NMI-Menu Vsn: 1.3.1 => so now it is possible to save and load snapshots with MB02+IDE
on IDE device as well as on FDD;
format is *.sna, devastace is also running, so there is no need of using additional Multiface
22.10.2007 ... some days ago I began to recreate / reorganize a new booting and utility disk which will contain only programs
which work with this hardware; all utilities will be commented, so user knows what for it is made;
utilities will be grouped for its functionality into named subdirectories
22.20.2007 ... first lot of PCBs just ordered - now I have to wait for plausibility statement of the producer, if there is no problem after
10 working days the PCBs will be send to me
20.10.2007 ... added jumpers for RESET line, replaced jumpers for ROM-selects of +48, +128, +2A/+2B/+3
layouted an additional board for RESET at +2A/+2V/+3 ==> in case of using one of this computers one have to remove
two jumpers (one for ROM-select, one for Reset) and instead of the jumpers place the additional board
(4 transistors, 1 diode, 4 resistors) - this board solves problems with RESET
17.10.2007 ... placed the socket for the 3 V backup lithium cell on the board (no cable neccessary)
14.10.2007 ... added optional 5 V - switching regulator to the layout - enables input 0f 7.5 V - 16 V
