Now that we have a goal in sight (bringing up BigMac in timely fashion), I thought we should formalize and agree on how we are to reach this goal. I see it as a four stage process. First is of course, the delivery of the breadboard machine on or about 8/15 to the software group. Second stage is to get some kind of debugging environment in the machine. Third is to download our version of The ROM into ram and get as much of it working as we can andlor as is necessary to boot. The last stage is to get the machine to boot up and hopefully run an application. I propose that we try to use the MacDB debugger from the MDS system. This debugger uses a Mac as a very intelligent terminal talking to a small monitor «1k bytes) in the target machine. This is a very powerful debugging system that is for the most part done and should require little to port to BigMac. The one thing that it lacks is the ability to disassemble 68020 code (ho'lVever I have a line on a possible updated version) but I don't see that as much of a problem as very little 68020 specific code is in the system. I have the sources to the monitor (Macl'~ub) and the debugger (MacDB) so that we can modify them as nee.d be. Tom will be providing a ROM image for BigMac to be downloaded and debugged. Rodger has been working on a debugger/downloader that we can modify to use the MacDB protocol for downloading the ROM image. Once the image is in RAM we can debug the initialization parts leading up to booting the disk. From my discussions with Tom and Rodger last week it was decided that we would boot from the hard disk. This is a win for two reasons. First it greatly simplifies the boot process by not having to get wrapped up in the Sony driver (and EEEK!, the IWM) and second it is too cool for words to boot from the hard disk. First pass is will be getting the Finder to run. With some luck their might be time to get Paint or Write to work. So much for my view of the world. Please let me know if you see any problems in this strategy or perhaps we can discuss it at the next BigMac meeting. team: Rodger Mohme Peter Ashkin Tom Saulpaugh Rich Page from: Mike Hanlon

Rich Page 6/29/85 Yideo/Sound Timing Gate Array: VIG The VTG implements the horizontal and power supply sync signals, the sound clock, the system timer and the interfaces for the front desk bus modem and the clock chip. The horizontal and power supply sync signals are derived from the video dot rate clock divided by 32 (ie. 2.1888 MHz) using a six bit counter and write registers 10 thru 13 which provide control of the horizontal period, horizontal blank stop, horizontal sync start and horizontal sync stop. The default at reset provides a horizontal rate of 1!l.75KHz and a power supply sync at twice the horizo~tal period at 99.5KHz. The refresh/sound counter is fixed at four times the sound rate using a divide of 41.5 from the 3.6864 Mhz clock which yields a clock of 88.8 KHz. The system timer is a, 16 bit counter which counts at a rate of one fourth of the 3.6864 Mhz clock (ie. approximately once every microsecond). The timer counts upwards to zero. When the timer rolls over to zero, a time out interrupt is generated (ie. s,ets ~ROJ and the system timer is loaded from the the system timer latch (write registers 6 and 7). The front desk bus (FOB) interface is a five line interface which is controlled by write register 4. The five signals are STO, ST1, FS7 (data), FC (clock) and FINT. The, FOB shift register is located at register 2. --===-;z The real time clock (RTC) interface is a four line interface which is controlled by write register 5. The four signals are CINT (1 sec interrupt), RC (clock), CE (clock enable) and RS7 (data). The VTG is located at $FFFOOP0~ with a register spacing of $10. There are six read registers and ten write registers implemented as follows: Bead Register 0: Status $FFFOOOO 0 Bit 0 SRO Status Reg 0, set by the RTC one second interrupt. Bit 1 SR1 ( Status Reg 1, set by the System Timer timeout. Bit 2 FINT . FOB Interrupt input. Bit 3 RSIN RTC serial data input. Bit 4 RA3 VTG Register Address bit 3 .. Bit 5 ES:E Enable ENC pin as sound counter enable. Bit 6 ErA Enable output buffer to RTC if set Bit 7 S10 Set if er~her SRO orSR1 is set.

Since you may be developiflg;expansion card produds which might interfere with the ROM daughterboard, we have also provided you with a set of masked ROMs that are electrically and mechanically identical to the final ROM.
