Apple II clones: “BOSS-1″ – Multi-System Personal Computer” – Part II:

 

board_with_z80_installed

The original power supply let the magic smoke out of itself and is been repaired by a fellow hobbyist. Meanwhile i took a power supply from the Apple //e clone that came built inside a IBM 5150 XT styled case as the pinouts were the same.

rom-card_for_boss-1_topside

I also got the original BOSS-1 ROM-card from Juha Seppänen of https://kakkostyypinomenat.blogspot.com a while ago. I dumped the ROM contents and they are now in Asimov archives if somebody needs them.

bad_ic_s

I inspteced visually the chips on board, pressed them down, cleaned some and swapped some as they had rusty legs on them. Luckily i have few clone boards that are great for donating parts now..

 

fixed_trace_s

There was some broken trace close to Slot 7, but it was reapaired earlier on. So i didn’t touch it.

 

boss1-rom-card_s

The BOSS-1 manual says to my understanding, that you can boot the BOSS-1 two ways:

-ROM-card installed to system slot that is the slot 0
OR:
-ROM-chip installed to location U6 that contains the “OS” (Applesoft) that should start an boot menu when unit is booted.

M.S.P.C. VAR 4.1
1) FP BASIC
2) Z-80 CP/M

So it’s basicly a boot-menu, after choosing what you want to use, you insert the floppy and press 1 or 2.

-First i tried with just the ROM at U6, but nothing, buzzing sound and garbage on screen.
-Then WITH the ROM-card, with the same results.
-Last just the ROM-card installed and the unit booted fine to text on screen “BOSS ][“.

When i got this unit in the first place, it came with the ROM-chip at U6, no Z80 CPU but a cloned Apple ROM-card with 6 x Applesoft ROM chips and it naturally booted “APPLE ][” on screen before the power supply releated the magic smoke (it wasn’t just the typical RIFA’s). But really it doesn’t matter, i’ll keep the original ROM-card in Slot 0 as it’s not a big deal.

boss_1_cpm

As i had some loose clone boards i removed one Z80 processor and installed it in BOSS-1 and CP/M 56k booted without a problem.

 

 

HARDWARE TESTING:

boss-1_setup_s

All ROM and RAM were OK. Colors are very vibrant when using JVC PVM 9″ CRT and not so much with a modern LCD. The colors when using modern LCD are hossibly ghostly, black & white.

50-60-hz_pads_s

The board is 60Hz NTSC. It’s pretty clear that your luck with Plus era Apple II’s and LCD’s is really depend of the model and maker of the display. I’ve not been able to get my Apple II PLUS units output colors with just swap of the crystal. 

Tested few cards to see how this clone would work as the ROM-card might cause issues etc.

 

RAM-cards:

saturn_multirom_cards_s

As the ROM-card needs to be used, there’s no ROM in main logic board, RAM cards do not work well. I tried with the original ROM card and Saturn Reboot 128k card as well original 32k RAM card but it didn’t work at all.

locksmith6ramcardok_s

Only with David Mutimer’s MultiROM card and Saturn Reboot 128k i was able to get 16k RAM card functionality, by installing the 128k card in Slot 0, and the MultiROM card in Slot 1 (Applesoft).

80-column card:
I had boxed clone 80-column card so i installed that. The monitor i used (9″ CRT) is quite small so it was difficult to read the text, but it did work. 

total_replay

Booti (ProDOS HDD-emulator)
Slot #6, booted Total Replay hdd-image succesfully and played some games. 

accelerator_s

Accelerator II (clone) 65c02@4MHz
3.58MHz, Slot 0 = MultiROM (Applesoft), Slot 1 = Accelerator II (clone), Slot 6 = Disk II interface + wDrive.


Game Controller DIP16:
There’s regular, standard DIP16 game controller connector on board where you can install the paddles or joystick.

Bebek Electronic catalog 1-3/1984

catalogs_1_3_1984_s

I found these Bebek Electronics catalogs from online auction site for few euro’s so i naturally just had to get them. I saw there were few ad’s about BOSS-1 clone that i have, so i was super excited to obtain any additional information about the model and it’s history. There’s so little information of anykind of this model.

 

Brief Bebek Electronics history:

“Bebek Electronic began operations in Lahti in the mid-1970s, when Resit Bebek, who first moved from Turkey to study in Germany and came to Finland after graduating as an electronics engineer with his Finnish wife, did not find a job elsewhere”.

– Then I had to try it myself.

“From Lahti, operations gradually expanded to Helsinki, Tampere and Kuopio. In addition to the four locations, supplies are  currently sold in the company’s own Bebek.fi online store”.

Some interesting ad’s from those catalogs:

boss-1

BOSS-1

boss-1c

BOSS-1c

 

hitachi_compact_3inch_drive

Hitachi 3″ compact floppy disk drive. These were sold in here in Finland in few places. I have one as well. The 3″ format itself wasn’t really popular, it was used in Amstrad computers in UK. It works as any floppy drive with Apple II, regular Disk II interface card will do. It’s dual sized.

cards_for_boss_mack64 cards_for_boss_mack_apple

Some cards they sold for Apple II and clones (MACK-48, BOSS-1). I assume those cards were also clones from Taiwan/HK.
I’d like to find that 6809-card long with the FLEX-OS they bundled it with. There were 6809 card made in Germany by IBS as well.

cards_for_apple_ii

These cards look clones as well to me.

I am very interested finding more about the BOSS-1/BOSS-1C computer so please contact me if you have anything about BOSS-1/1c.

Also interested if somebody have more of these Bebek Electronic catalogs from 1980’s.
